At present, the world made linear reducer, to do more in Japan, better. The basic structure of the pendulum reducer includes input eccentric roller bearings, planetary cycloid gear teeth, body and outer pin teeth, etc.. The characteristics of the pendulum reducer is that it can be found that the speed reduction ratio is high and the range is large, and the reduction ratio of the single-stage drive is 50~200. The transmission efficiency is higher than the worm gear reducer, and with the reduction ratio, the efficiency of the single-stage transmission is 60 ~ 70%. Another characteristic of his is that the torsional rigidity is lower due to frictional motion.

This kind of machine is that: because it is part of eccentricity, friction movement, transmission assembly is easy to wear, a shorter working life, and the machine is easy to produce temperature heating, so allow the input speed is not high, but also in the following 2000rpm.

Worm gear reducer is composed of input and output characteristics of the worm gear, transmission torque is high, speed high and large range of speed single stage transmission ratio is 5 ~ 100; the input and output of the coaxial transmission mechanism does not belong to the application, is not easy, and the transmission efficiency is low, not more than 60%.

The industry said, because it is a kind of sliding friction drive, worm gear reducer torsion rigidity value is slightly lower, and the transmission assembly is easy to wear, short service life, and easy to produce temperature reducer, so allow input speed is not high (2000rpm), which limits the use of worm.
