Worm gear speed reducer is a compact, with big transmission ratio and with self-locking function.
A general problems for this are high temperature and oil spills and worm bearing damage.
Then solving these problems, how do we want it? Next we come to analyze.
1. Selection of lubricants and additives. Worm gear reducer 220 # gear oil is generally used for heavy, frequent starting, the bad environment, which can use some lubricant additives. so when you stop running gears, oil is still attached to the gear surface, forming a protective film to prevent direct contact between the metal heavy load, low speed, high torque and starts.
2. The establishment of lubrication maintenance system. According lubrication "five" Principles of gear maintenance, so that each person has a responsibility to gear regularly checked and found significant temperature exceeds 40 ℃ or oil temperature exceed 80 ℃, the quality of oil drops or oil We found more copper and produce abnormal noise and other phenomena, should immediately stop using and timely maintenance, troubleshooting, replacement of oil. When refueling, pay attention to oil, to ensure correct lubrication gear.

3. To ensure assembly quality. Can be purchased or made at a number of special tools to remove and install gear parts, try to avoid tapping with a hammer and other tools; change gear, when worm, try to use original parts and be replaced in pairs; assembly output shaft, pay attention tolerances; to use anti-adhesive or red lead oil to protect the hollow shaft, with the area to prevent rust or dirt wear, difficult disassembly maintenance.
4. Select reducer installed. Lower position permitting, try not to use vertical installation. When installed vertically installed a lot more than the amount of the lubricating oil level, could easily lead to fever reducer and oil spills.

For the 21st century is an industrial society and assembling of conveyor line in the mass production is indispensable in many enterprises and factories. Many manufacturing jobs on production line has been from manual assembly into semi-automatic or automatic assembly. Conveyor line assembling is by changing the belt speed to meet the requirements of different production processes. For this reason, the gear reduction motor is the necessary spare parts for the conveyor line body. The following conveyor line is a example diagram.
Cross arranging is the most commonly used in transmission belt line, using the continuous or intermittent movement of conveyor belt to convey various light and heavy items, such as the transport all kinds of powder, all kinds of cartons, plank, bags, etc. Conveyor line has a very wide usage range. With the rapid development of the automatic production, Selection of gear reduction motor has become one of the important work of the engineers.

Assembling conveyor line dedicated gear reducer motor need to be considered in the selection of what respect need to consideration?

1 How much big for the start power and load torque of the convey line?
2 Is Speed adjustment convenient and the variable speed is in line with the requirements for The one selected?
3 the gear reduction motor size is in accordance with the equipment installed outside the body space;
4 Is it forward reverse ?
5 the work environment if there are special circumstances, such as the temperature too low or too high, larger amount of dust, corrosive or other chemical gas or liquid and so on.

Speed reducer industry, as China's major equipment with mechanical means, which has a important applications in all areas of the national economy and defense industry. For the past two years, China gears industry's technological transformation, doing a series of investigations, particularly in terms of the gear reducer, particular emphasis on stability and enhance the efficiency of economic growth, research import and export situation, strengthening the deep adjustment reducer industry .

Our country in these areas have done a lot of work and effort. First, China's implementation of standardized construction slowdown in the industry in order to meet the national industrial development strategy. Standardization strategy aimed at implementation of technological innovation, so that the industry by the policy-oriented, trend-oriented speculative demand-oriented, technology-oriented small and medium enterprises all over and get rid of the status quo no real coordination of industrial clusters development. To this end, our enhanced industry-standard access mechanism, will manage to advance to the corporate design, research and development, and strive to make it meet the requirements of the development of the industrial sector. Backward production capacity and excess production capacity is Zhiai factor in the development of standardization strategy to coordinate the newly overcapacity in production relations and, through the elimination of backward production capacity, absorb the excess capacity means of alleviating the industry burden, and strengthen the standardization of innovation and basic research.

Second, the development of the industry needs to cultivate strong productivity part, especially the brand strength. The implementation of medium-sized enterprises active support policies, foster large-scale enterprises in the international competitiveness of the industrial environment and maintain the momentum of the industry, so that the leading industry role in promoting enhanced. Actively involved, indirect guidance, are effective means of development. If they could have a few more of the large group of gear business, it must be able to maintain a certain advantage in the competition with foreign counterparts in.

China reducer Network noted, in general, China's reducer enterprises compared with foreign products in development and innovation has been slow, the independent production of some gear transmission equipment is basically a generic product, lack of development momentum. So companies want to fight for our gear in the high-end market share, we need to actively seek market opportunities, and take a new path of development, in national standardization strategy continues to advance the process, to grasp the development direction and strive to grow and strive in the "five-second" new year to obtain greater momentu

11. S..R. This is combined types which are the S series right angle gearbox and R series helical inline gear units. This can get a bigger ratio and can reduce the electric motor speed much lower.

As new product, Rotary gear drive has been the most popular in transmission industry. For its high scientific design and high production capacity requirements, making the rotary gears reputable. So what applications will rotary gear have? Slewing Drive can be used in the host of a circular motion machine, such as a crane turntable, rotating machinery, and some mechanical work in a circular. The products can be widely used for the truck crane, which represented engineering machinery and new energy as photovoltaic solar power represented, as wind power represented, and also other automation, machine manufacturing, aerospace, communications and other fields etc. we can say that, the market potential of the product is huge Here below is the field:

1, Beam carrier field: Traditional beam carrier’s core components is using traditional slewing ring product mostly, compared to the rotary gear drive, the old one has no slewing bearing housing, and corrosion resistance is bad. Moreover, by the hydraulic cylinder to push the tires steering systems, tire rotation angle is in a very limited range. Using the rotary gear device as a rotating part, not only can improved the corrosion resistance, also increase the steering angle of each set of tires.

2, Aerial field: Aerial is an important field of using rotary gear drive and the aerial device usually requires a higher safety factor. (self-locking worm) rotary gearbox’s the majority factor for users to choose is its high security. On the other hand, worm gears have a wide transmission ratio.

3, The Photovoltaic field: Photovoltaic power generation is an important application of rotary gearbox, using slew drive as a rotating component of solar PV modules, it can adjust a the precise angle according to the position the sun with a different location ,in best reception angle.

4, The wind power generation filed: Same as the Photovoltaic field, rotary gear drive can be used in wind turbine and achieve the level of organization of 360 ° rotation, in order to better adjust the angle of the receiver.

As a widely used type power transmission drive, R series helical gearmotor plays very important role in industry manufacturing. 

All dimensions of our R serial gear speed reducers are same as SEW's R serieal. Which can be well coupled as a replacement, but much more cheaper. We have multiple kinds of mounting ways for this type, foot mounted, vertical mounted, flanged mounted, long shaft mounted, and others. The gears from two stages to four stages, which can make larger torques.

For the motor connected, It can be coupled with AC motor or DC motor.

For AC motors, Y2 series standard electromotor or YD two speed electric motor or other types motor.  IEC motor NEMA motor can be fit as well. In a word, we can change the flange of the inoput side of the gearbox to make well fit in the types of motor. 

For the DC motors, we usually connect with Z4 serial DC motor whose power from 0.05kw to 300KW. There are plenty of mounting ways, from top to bottom or left or right. It concerns about the oil leaking. So this is a important factor for customer to choose the right model. 

Each powder drying mixer will be mounted on a reducer at the top next to the motor, mostly due to the mixing shaft operating speed range is within 30-600rpm far less than the rated speed of the motor, needing to mount a gear reducer at the end output shaft of the motor, which is a independent closed power transmission gears between the AC motor and the working machine to reduce speed and increase torque accordingly.

In accordance with the driving and structural characteristics, it can be divided into cycloid reducers, belt pulley reducer, worm gear reducer and helical gear reducers, when we choose the right gear reducer according to process requirements and operating environments Optional machines, in addition to satisfying the selection of output power and speed requirements should be easy and reliable operation and maintenance of high mechanical efficiency and low noise. Now we come to recognize that these four were reducer, learning under their works.

Packaging machinery is widely used for food, pharmaceutical, printing and other industries, with raise of people’s consumption, it brings a huge space for development of the China's packaging machinery. As the needs of various industries for packaging machinery is rising year by year, China's packaging machinery has been unable to meet the needs of many industries. Domestic packaging machinery company should actively look for ways to be better-developed from the demand of industry.

At present, China's packaging machinery manufacturing skill levels diversified, weak capacity, development of competition in the market has not kept pace. Now, some packaging machinery companies have increased ability to innovate, and actively adjust the product structure, basically meet the market demand, but there are still some products relied on imports.

In recent years, as China's technological level and that the gap is growing, investment in research and development enterprises accounted for 1% of business sales, the business to survive, accounting for 2% can barely accounted for only 5% competitiveness, and investment in research and development for an average of less than 1%.
According to statistics, the national R & D expenditure accounted for only 0.3% to 0.5% of corporate sales, R & D personnel employed only 3.4% to 4%. Abroad, a serious shortage of investment in research and compared, resulting in a low degree of automation equipment industry, with an average of 4 to 6 times the energy consumption in developed countries, it is difficult to meet the market demand. More large equipment performance gap, advanced model is about 1/2 of the advanced level, the overall level of technology behind the developed countries about 20 years.

According to local news in Myanmar on March 20, the Myanmar Commerce Department said, they will permit import of the used machinery and equipment from March of this year, in order to promote the development of Small and Medium-Sized Enterprises. Because of imported second-hand equipment is much more cheaper than the new one, to the businesses, buying used equipment can get greater profit margins and also can ease the financial pressure on SMEs. Commerce Department also said that in order to avoid becoming the focus of waste equipment developed markets, Myanmar imported second-hand equipment to strict import policy will be adjusted annually. Used equipment imported only allowed to be by sea through border trade imports. Prior to this, the Burmese do not have to allow imports of second-hand equipment.

K seires gearmotor is a right angle mounting way with helical-bevel gearing sets.  Industry Standard. Our dimensions of this gearmotor is exact same as SEW europedrive's. and aslo for the model number. So it is an ideal replacment for this famous brand. Quality is competitived but lower prices.

The helical-bevel gears gives a more efficiency than other types of gearing such as helical-worm types. Some clients often misunderstand these two type gears. Actually, they are much different. The helica-worm gearbox has a low effiency and right for some light industries. and the helical-bevel gears are higher price than the helical-worm type. Of course, in a suitable industry to choose a right model, this is the key.

Our K series gear reducers can be with motor in VFD or brake or both. In the gearhead, it also can be coupled with a torque arm, some calls Mounting plate. they are same. To provent the complete sets move and easy to operation. The complete sets with gearheads and motor, is in various mounting. Upper or  down or left or right. Almost for every usage industry. 

Output shaft can be made in a spline with key which is usually for crane or hosit duty. For the helical bevel gearbox, there might be  two soild shafts or hollow shafts output in both sides.

Input part, it is with flange to couple a electric motor. It is easy for the maintance. Also, the gearhead can be sole usage. with solid shaft input type.In the houllow shaft type, if needs, it can be with a shrink disk to controll the diameter of the output hole. 

Rotary feeder can be used as the bunker discharger in the material collecting system. Rotary feeder is the most advanced discharging device currently and commonly used as one of important equipment in dust removal system.

The temperature of conveying material can reach 280℃. On both ends of bearing and impeller has a certain isolation, which can prevent the superfine powder contacting the bearing. Connected by sprocket, The temperature of conveying material for high temperature resistant type discharger can reach 500 ℃. The cycloidal gear motor reducer and discharger shell has certain distance.

The Rotary feeder composition is made with the number of leaves, seals and motor reducer, motor rotor impeller, shell and so on. The star discharging device, also known as rotary feeder, lock valve, star discharge valve, the star feeder, rotary feeder. As a special kind of unloading equipment, Rotary feeder plays a large role in the cleaning and washing work, and it is necessary to summarize its characteristics. So we can make a better understanding of the rotary feeder to do comprehensive and maintenance.

As talked on yesterday, we are here now to introduce the fours types of Gear redactor in power transmission industry.

Cycloid gear reducer, using cycloid tooth meshing is an advanced design, new style structure of the reduction way, which can be both clockwise and reverse operation. The biggest feature is that it has the high transmission efficiency and also a wide ratio transmission range. And power is available from 10KW to 50000kW. Otherwise, its size and weight is much smaller than helical gear reducer and worm reducer. However, its structure is more complex high precision. It is widely used in petrochemical deceleration devices, light industry, pharmaceutical industry, textile, metallurgy, mining, sewage treatment and construction machinery and other transmission machinery.

Belt reductor, speed redactor with belt, it is high efficiency, long life, compact structure, smooth transmission, easy removal and other features that allow positive and negative direction of running, in large fermentation devices more often.

Worm gears, worm gearbox with worm gear drive is mainly used for large occasions, with smooth contours and other transmission compact size advantages of small work, but less efficient single-stage worm reducer thus used more two-Worm reducer is seldom used. Range of single-stage worm gear transmission ratio is generally 10-70.

Gear reducer, it mainly gets cylindrical gear reducer and bevel gear reducer. cylindrical gear reducer which is the most widely using. which can deliver the power range from small to 4000kW peripheral speed is also available from low 60-70m/s; and the input shaft and output shaft position bevel gear reducer to 90o configuration making it suitable for input and output shaft perpendicular to each other occasions. The main features of the gear reducer is durable and easy to maintain high efficiency, according to the reduction gear stages can be divided into single-stage, two, three or even multi-level, avoiding gear outside dimensions too large, generally when the ratio of 8 The following can be used when a single-stage gear reducer, the best selection of two or more stages and it is greater than 8.

Recently, India launched anti-dumping investigations to China cold rolling and hot rolled stainless steel products. and even levied anti-dumping duties, it will increase China's stainless steel products export pressure, influencing on the export of stainless steel.
India commerce ministry had made a statement that will make final anti-dumping on the imported 304 series hot rolled stainless steel, suggesting to levy anti-dumping duties on 304 series of hot rolled stainless steel come from China, South Korea and Malaysia
A Shanghai analysts said that this statement will increase China's stainless steel products export pressure, in 2015 China's steel export situation which is not optimistic, export of stainless steel products will also be suppressed.
In addition to hot rolled stainless steel products, the same to cold rolled stainless steels. In early the end of 2014, Indonesia's anti-dumping committee made announcement that according to the domestic industry application, decided to levy anti-dumping investigation for cold-rolled stainless steel from China, Thailand, Malaysia, South Korea, Singapore and Taiwan.

China is one of the biggest stainless steel producer and stainless steel output production gets half of the world's for many years. With the rapid development of the stainless steel industry, the export of Chinese stainless steel also sustained and rapid growth.

According to the data of China special steel enterprises association shows that in 2014 China's stainless steel production increased 14.27%, coming to 21.692 million tons which means almost half of global’s. All over 2014, China's export of stainless steel is 385 tons and increase of 1.197 million tons, a 45.12% increasing.

First, the selection of the planetary gear ratio selection:

When choosing a planetary gears, we must first get reduction ratio. determined after reduction ratio, add your choice of servo motor rated torque multiplied by the reduction ratio, the value obtained is less than the principle product samples provided similar gear rated output torque , but also consider the maximum operating torque of the motor overload and actual required driving. It is less than the required maximum operating torque of 2 times nominal output torque.

Second, get the size specifications planetary gear:

Please select the smallest gearbox after the above conditions which meets, small size and relatively low cost reducer. If you have enough space motor reducer straight line connection, you can also select a corner reducer, it can turn 90 degrees to the torque.

Third, the precision planetary gear (backlash) selection:
