Seeking New way to the development of gear reducer industry

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

S series gearmotor

S series helical-worm gearmotor is replaceable to SEW  S series motor reductor. Inside with helical and worm combined gears, this gearbox is used in light industry mainly such as Textile, food, water industry etc. The efficiency is lower than the helical type , R series helical gear reducer. But the advantage is that it is cheaper and compact. Easy to install. Moreover, it has self-lock function which most other type gearbox not have. 

The output shafts of our S series are vertical to input shafts. Units of S series consist of single stage helical gears and single stage worm gears. There are many mounting types for the installing.

The main types of our S series is as following:

1. Horizontal type, with foot mounted and solid output shafts. Two sides output or single side.

2. B5 flanged mounted helical-worm gearbox with solid shafts. There are holes in the flange for the installation  

3. SA series gear units with hollow shaft output. The diameter of the hollow shaft can be changed according to customers’ requirement in certain range.

4.SAF series speed reducer with B5 flange and hollow shaft. This type is combined type with item 2 and 3.

5.SAZ series geared motor. This type mounted with a B14 flange which is smaller than B5.

6.SH series helical-worm gear reudctor with hollow shaft and shrink disk. This device is installed in the output hollow shaft and it can lock the shaft coupled in the hollow and can used in some places that need stopping and starting very often.

7. SHF series with B5 flange and hollow shaft and shrink disk. This type has the fuction of above item 4 and 6.

8. SHZ type gear drive with electric motor. This one have a B14 flange and hollow shaft and shrink disk mounted.

9. SAT/SHT gearmotor type. With torque-arm-mounted, it can fix the entire geared motor tightly. SAT is a hollow shaft with torque arm and SHT is hollow shaft with shrink disk with torque arm. When this gearbox works, the torque can stop the complete unit shake. This is very useful.

10.S..SZ..AD. Compared to the above types, this type is with no electric motor coupled and the input part is with solid shaft. And the output part is also a solid shaft.

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.

Packaging machinery industry

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.

High Efficient motor rapidly developed with policy support

With China's accession to WTO, the domestic motor industry faced enormous competitive pressures and challenges. Seeing from the international and domestic development trend, developing China's high-efficiency motors is necessary and it is also a market requirement. So that make our electric motor products keep up with the international trend,. According to statistics, in 2002 China accounted for more than 60% on the electrical motor power consumption of the country. And the power is about 35%, which is power-hungry.

three asynchronous motor

 

It is reported that China's industrial energy consumption accounts for 70% of total energy consumption, including electrical energy consumption accounts for 60% to 70% of industrial energy consumption, coupled with the non-energy industrial motors, motor actual energy of the total energy consumption more than 50%. Now low proportion of applications of energy efficient motors. According to the National Quality Supervision and Inspection Center of small motors for domestic motor 198 key enterprises sample survey, the proportion of energy efficient motors which reach more than 2 only 8%, which on the whole society had a tremendous waste of resources. Why efficient motor has not really enter the market? The higher prices, the market situation is not ideal, so that fewer manufacturers, resulting in user awareness of efficient motor is not enough, this is one of the main reasons. This year, the Ministry of Industry on March 26 issued the "2013 industrial energy efficiency and green development special action plan" put forward the notification, in 2013 will focus on promoting the implementation of special programs to enhance the energy efficiency of the motor. Target special action is: to achieve savings of 1% of the country's industrial electricity consumption (about 300 million degrees), to explore the pattern of industrial energy efficiency and green development and implementation of ways to achieve a point, and drive energy conservation and comprehensive utilization of overall industrial progress. According to an embodiment, in 2013 the Ministry will promote efficient motors, eliminating six aspects of the existing inefficient motors and motor systems and other aspects of energy-saving technological transformation, extension, elimination and energy-saving motors and motor systems 100 million kilowatts, expand market share high efficiency motor and promote the upgrading of electrical products and industrial upgrading. Thus, the government is to promote efficient motor, but needs to continue to increase promotional efforts. But in the current market economy, short-sighted companies are reducing their procurement costs, which is a high efficiency motor price become a contradiction. Therefore, the promotion of efficient motors also need politicians to improve the focus on efficiency, high efficiency motor conduction efficiency can quickly link to the downstream market in order to present the hugely popular scene.

Gear Lubricants knowledge introduction

Gear Lubricants knowledge introduction
Bevel gear, helical gears ,cylindrical gear (SPUR GEARS),spiral bevel gear,worm snail bar (WORM & WORM WHEELS),reducer (SPEED REDUCERS) / gearbox, etc.
Gear Lubricants referred gear oil, which is mainly used to lubricate the various mechanical gears.Gear oils and engine lubricants, as also the group consisting of mineral oil type (or synthetic) base oil and additives corresponding
A. Gear oils and gear oil can be divided into two categories industrial gear oils.
Gear oil Introduction
Vehicle gear oil is mainly used in automobile, engineering machinery transmission, steering, front and rear drive axle. Gearbox, universal joints needle bearings and other parts, but also for tanks, ships, and the corresponding load and working conditions
Gear member. Industrial gear oil is mainly used to open under various load conditions, semi-open, closed and Worm gear.
First, the gear oil working conditions and its role:
A variety of mechanical transmission gear mechanism, according to its different axes of the mutual positional relationship can be divided into parallel Shaft drive, intersect and cross shaft drive shaft drive. According to the shape of each type of transmission in different gears and teeth have different
Transmission methods, such as parallel shaft drive spur gears, helical gears, spur gears herringbone; Intersecting axis drive straight bevel gears, helical bevel gears, spiral bevel gears; staggered shaft drive has hyperbolic
Gears, worm, helical gear.
1. gear characteristics and working conditions of gear oil
    (1) high-efficiency gear, generally cylindrical gear transmission efficiency up to 98%, compared with the bearing, gear
Equivalent curve radius wheel is small, wedge poor conditions.
    (2) gear tooth is in line contact with the teeth, and therefore, the contact area, contact pressure units high.
General Automotive gear unit contact pressure up 2000-3000MPa, while higher hypoid gear up to
3000 a 4000MPa.
    (3) gear not only line contact, there is sliding contact, especially between the hypoid gear, tooth
They have a higher relative sliding velocity, generally up to about 8m / o. This is in the high speed high load conditions, will
Thin film and even a partial rupture, leading to increased friction and wear, and even cause abrasions and bite.
    (4) gear oil operating temperature is generally lower than the internal combustion engine oil, in large part with the ambient temperature changes
Changes, vehicle gear oil temperature is generally not higher than 100'C. Modern cars use hypoid gear, its axis
Line a large offset high gear side will ask the vehicle speed is high relative sliding speed, the oil temperature reaches
160'C a 180'C.
2. The role of gear oil in the gear
   (1) reduce wear gears and other moving parts, prolong gear life.
   (2) reduce friction, reduce power loss.
   (3) dispersing the heat, since a certain cooling effect.
   (4) to prevent corrosion and rust.
   (5) reduces operating noise and reduce vibration and shock effect between gears.
   (6) washing the dirt, especially among rushed tooth surface dirt, reducing wear and tear.
Second, the gear oil properties:
The purpose of the use of different gear oil, conditions of use varies widely with its performance as follows Claim:
    1. Good oil and extreme pressure anti-wear
    Oily refers gear oil can effectively adsorb oil film lubrication between moving surfaces, have lower
The nature of the low friction. Abrasion resistance refers to the oil held in the oil film between the moving parts, can effectively prevent the metal
Direct contact between the ability to add some of the active substance with polar molecules in the gear oil can improve its oil
Sex, oxides of these oily agents polar end and the metal surface adsorption occurs, to form a strong oily
Membranes, polar end oiliness agent may also form a metal soap type lubricant film and the metal oxide surface, to strengthen the tooth
Wheel lubrication oil, to prevent direct contact tooth surface, to reduce friction, thereby reducing wear. Some of the gear transmission
Move, often working under extreme pressure lubrication harsh conditions, the pressure, sliding speed and local temperatures
High, which requires adding extreme pressure gear oil additives. Extreme pressure additives are typically chemically active
Parathion, parathion chlorine-type or oil-soluble zinc compounds, these additives at high temperature and pressure conditions and extreme metal tooth shape
To iron chlorine, sulfur, phosphorus compounds or complexes, to form a high melting point of the inorganic film, this film has a very
Extreme pressure resistance properties, but also have the role of resistance to shock loading, can be effectively prevented under high load conditions
Tooth surface scratches and bite.
2. Good viscosity-temperature characteristics
      All kinds of lubricating oil viscosity decreases with increasing temperature, the smaller the proportion of decline, its viscosity-temperature performance
The better. Especially in the automotive and construction machinery gear oil operating temperature range varies greatly, therefore, hope that the gear oil
Viscosity change with temperature as low as possible. Gear oil viscosity-temperature characteristics as well, when you start the viscosity is too large,
Easy to start, and run to a temperature high limit viscosity is too small. Viscosity gear oil is also important usability
One great energy, viscosity influence on the formation of the oil film. In general, high viscosity gear oil can effectively prevent the gear
And bearing damage, reduce noise and minimize leakage mechanical operation; low-viscosity oil to improve the operating efficiency of machinery plus
Transmission is stronger cooling and cleaning action and the oil has an advantage. In order to reduce fuel consumption, foreign introduced hair
Engine oil, gear oil of low viscosity. The advantages of low viscosity gear oil agitating resistance is small gear teeth, and
Has good low temperature fluidity, at low temperature to ensure lubrication. In recent years, the country has produced some of the low viscosity
Degree of gear oil, in order to change its lubricating properties and Poor's added some pleiotropic additives which reduce power loss
Is very favorable. Of course, in the use of its body, to strengthen the gear box sealed to prevent gear oil
Leakage.
3. Good low temperature fluidity
    Automotive gear oil requirements at low temperatures can maintain the necessary fluidity, if the gear oil at a low temperature strip
Lower member wax precipitation, a sharp rise in viscosity, it can not ensure effective lubrication, low temperature start torque is increased, so that
Was an increase in fuel consumption.
   Tests showed low apparent viscosity gear oil lubrication reliability of the vehicle starting an important shadow
Ring. Inflows driving bevel gear axle vehicles after the start, rear axle (front axle) gear oil is Jijian to upper rear axle housing
Cheng, when asked if this is too long, there may be due to lack of oil bearing burned. Therefore, the requirements of the vehicle so that the gear oil
With the apparent viscosity at low temperature of not more than 1.5X100000mPa.s. Vehicle gear oil specifications apparent bid out
1.5X100000mpa.s temperature viscosity when it determines the gear oil for the minimum temperature, the election
One important basis for gear oil used. In order to be able to adapt to the requirements of gear oil under low temperature in winter conditions, tooth
Round to join the oil pour point depressants, to improve its low temperature fluidity.
4. Good thermal oxidation stability
     Gear oil under severe operating conditions, in air, water and metal catalyzed oxidation rate
Accelerate, the viscosity increases, resulting insolubles and corrosive substances and resin and asphaltene, nature deterioration and easy milk
Technology and produce foam, so Huanyouzhouqi shortened. To retard oxidation gear oils, typically added phenol in oil,
Amine or curing type antioxidant additives.
5. Good rust and corrosion
   Rust resistance refers to the gear oil to protect gear from corrosion, thus ensuring performance and prolong gear so
Life. Gear during operation, the moisture in the air condenses into water gearbox, thus requiring gear
Oil should have good rust resistance. In order to enhance rust resistance gear oil, generally added salt or salts of fatty acids
And other anti-corrosion additives. Plus there is extreme pressure gear oil additives, extreme pressure additives due to sulphide, sulfur on copper
Easy to produce corrosion, therefore, to join in the gear oil in anti-corrosion additives, which can form on the metal surface protection
Protective film to prevent corrosion of metal corrosive substances.
6. Good anti-foam
   Gear oils requires a good anti-foam to ensure under operating conditions, intense stir in gear
Mixing process produces less foam and easy to disappear.
