The top 10 gear manufacturing companies in world。Gear mechanism is one of the most widely used transmission mechanisms in modern machinery.The top 10 gear manufacturing companies in world。 It can be used to transmit motion and power between any two axes. It has a large transmission power range, high efficiency, accurate transmission ratio, long service life and safe operation. Reliable and so on.


The gear mechanism is a high-assist mechanism and is widely used in various mechanical equipment.
The gear transmission is an intermeshing transmission.The top 10 gear manufacturing companies in world。 Its main advantages are: the instantaneous transmission ratio is constant; the applicable peripheral speed and power range are large (speed up to 300m/s, power can be from 1W to 100000kW); The top 10 gear manufacturing companies in world。transmission efficiency is high (up to 0.99); Reliable work, long life (up to 10~20 years); compact structure. However, the gear manufacturing is complicated and requires special equipment; The top 10 gear manufacturing companies in world。the gear with low precision has large noise, large vibration and impact during transmission; it is not suitable for transmission between two shafts at a long distance.The top 10 gear manufacturing companies in world


In the research, design and production of gear transmissions, the following two basic requirements are generally met:
1. The transmission is stable - keep the instantaneous transmission ratio constant in the transmission, and the impact, vibration and noise should be as small as possible.
The top 10 gear manufacturing companies in world,the carrying capacity is large - under the premise of small size and light weight, the gear teeth are required to have high strength, good wear resistance and long service life.
