ZLYJ series extruder gear reducers revision notice.

November 1, in the effort with group purchasing and quality assurance departments, under the careful development and manufacturing of a lean manufacturing technology sector, the country's two new revision ZLYJ173 Mao and ZLYJ200 prototype, once developed. Older contrast, the new revision of these two ZLYJ series gear reducers products, mainly significant breakthrough following five aspects -
First, the original wooden box mold mold, all replaced by a new design of the mold. Mold has three advantages: 1, casting surface is more smooth, flat, you can spray paint directly on the surface, eliminating the old original box Pihui milling and grinding processes, not only shorten the processing cycle, and improve efficiency, but also cost savings. 2 directly wooden mold easily exclude defective situation legacy foundry sand in the box in the corner. 3, according to the mechanical requirements, the new design is more compact shape, adding many rounded design, better thermal performance, while products are also more in line with the requirements of modern industry artistic taste.
Second, the internal high-speed shaft bearing original tapered roller bearings, replace all self-aligning roller bearings. Aligning bearings have three advantages: 1, self-aligning bearing operation more stable, longer life. 2-aligning bearing on the accuracy of axial clearance adjustment, requiring significantly lower and easier to mass production. 3, self-aligning bearing, even when the axial movement is generated, not like, like the formation of a conical taper bearing exercise, causing fatal injuries to seal. Thus, the lower the probability of oil spills.
Third, through technological innovation, high-speed level labyrinth seal cover method, a single seal structure, compared to the old conventional double seal structure, not only reduces the probability of oil spills, but also cost savings.
4. All ZLYJ225 following models, the combination of surface screws from the original studs, replace the unified hex screws. Hexagon has three advantages: 1, hex screw stud directly ruled out opening and closing boxes difficult and fragile and screw nut length protruding level of inconsistency, the disadvantage intractable. 2, the appearance of a more unified appearance, assembly efficiency improved significantly. 3, some screw models, with other GM models, reducing the material type, easier purchasing and inventory control.
Five, after a new optimized design technology sector, external lubrication pipes have such three advantages: 1, more uniform appearance of lines, modular, to eliminate the appearance of older products are not unified, greater randomness shortcomings. 2, reducing the technical requirements for piping layout, making it simple, simple, and easier to operate. 3, small machines increases the external piping type small filtering equipment, so cleaning and maintenance, easier, simpler, and improved lubrication conditions, extending the life of the equipment.

The way to oversea market of the engineering machinery

With the rapidly changing world economy by the international economic situation, the domestic economy into the new normal. And as China's construction machinery industry basis, has been a four-year downturn. Overcapacity, insufficient market demand persists. In this market environment, "along the way" strategy proposed like a panacea, into the long-sluggish construction machinery industry.
In construction and along the domestic construction, machinery as a necessity in the process of roads, railways, airports and other infrastructure, and become an indispensable machinery. Excavators, loaders, bulldozers and other machinery products are in a big demand and will be the direct beneficiaries of the infrastructure. Engineering machinery industry began to take along all the way to the east, the momentum out to sea. Then, on the way to the sea of mechanical engineering, what are the difficulties and challenges?

On June 18, 2015, Liugong global R & D center was officially inaugurated and National Engineering Research Center for earthmoving machinery listing ceremony was held in Guangxi Liugong. It not only enhances Liugong research and development, but also will become an important milestone in the development history of Liugong. Zengguangan, who isChairman of Liugong, said that in Liugong building and investment will be without any slowdown and hesitation. Because they know that establish R & D center is not only a matter of the future of the core competitiveness of enterprises, but also related to the China's construction machinery industry morale.

Liugong's initiative is a microcosm of the whole construction machinery. As technology advances and innovative technology industry, there is a a huge progress in product development and manufacturing, from relying on technology imports to absorbed into a completely independent technological innovation, China's manufacturing industry has been rapid growed. Data shows that main share in the major overseas markets continued to rise, such as that the United States imports from China accounting for construction machinery increased from 10.08 percent in 2012 to 12.02 percent and the Asian market grew from 43% to 47% and the African market from 12% to 15%.

Studies have shown that, as in Zoomlion, Sany, XCMG, Liugong who are the construction machinery leader in technology research and development has always maintained the attitude of the times of business, have a good export performance. This is also from the side, excess capacity is relative, continuous technological innovation, to make technology products with core competitiveness, will not excess capacity.

The reason why using helical type in gear reducer manufacturing.

The main disadvantage is that they helical gear is vibration. Whether it is due to the design, manufacture or deformation, etc., at the same time along the entire tooth surface may occur some changes involute shape. This will lead to a regular, once per tooth incentives, it is often very strong. The resulting vibration caused both large load on the gear, and cause noise. Another negative point is that the contact time, and sometimes additional strength by two pairs of meshing obtained and can not be used, because the stress is circulating in the situation of a single tooth meshing defined.


Helical gears can be seen as a group of gear misalignment sheet should be placed into the cylindrical gear, so that each piece is touching a different part of the tooth profile, resulting in the role of the compensation of each sheet gear error, the compensation due to the wheel elastic teeth and is very effective, and thus come to such a result, the error is within 10mm of teeth can make the error from the average effect, which under load conditions, can such error is within 1mm teeth as running smoothly. Because in any transient, about half the time (assuming the coincidence of about 1.5) will have two teeth mesh, which brings additional benefits in terms of strength. Therefore, the stress can be established in 1.5 times the tooth width, rather than a tooth width of the base.


Manufacturing and assembly spur a lot of flakes is both difficult and uneconomical, and therefore manufactured integral gear teeth along the helical direction of the gear. Helical gear is not as straight, it will lead to undesirable axial force. But the benefits in terms of vibration and strength far better than the disadvantage caused by the axial thrust and a slight increase in manufacturing costs brought. So use helical gear rather than straight gear reducer such as the manufacture of four series:. R series coaxial helical gear reducer, K series of spiral bevel gear reducer, S series helical worm gear reducer, F series parallel shaft helical gear reducer Note 1: What is a spur gear: Spur is parallel to the shaft of the gear teeth. We will only discuss the parallel shaft gear theory, therefore, any money perpendicular to a cross section of two gear shaft are identical.

Some FAQs for worm gear speed reducer

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.

 

Selection of gear reduction motor for conveyor duty

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?
