Cycloidal pin gear reducer is a novel transmission mechanism that adopts K-H-V planetary transmission principle with little tooth difference and meshing of cycloidal pin teeth. It is widely used in driving and decelerating devices in the fields of textile printing and dyeing, light industry and food, metallurgy and mining, petrochemical industry, lifting and transportation and construction machinery.
At present, cycloidal reducers are manufactured in the world, and Japan has done more and better. The basic structure of the cycloid reducer includes the input eccentric roller bearing, the planetary cycloid gear plate, the body and the outer needle teeth. The characteristic of the cycloid reducer is that it is obvious that the reduction ratio is high and the range is large, and the reduction ratio of single-stage transmission is 50-200. The transmission efficiency is higher than that of a worm gear reducer. With different reduction ratios, the efficiency of a single-stage transmission is 60-70%. Another characteristic of him is that due to the frictional movement, the torsional rigidity is low.
The disadvantage of this type of machine is that because it is eccentric and frictional, the transmission components are easily worn out, the working life is short, and the machine is prone to heat generation and temperature rise, so the allowable input speed is not high, and it is also below 2,000rpm.
Worm gear reducer is composed of input worm and output worm. It is characterized by high transmission torque, high reduction ratio and large range. The reduction ratio of single-stage transmission is 5-100; transmission mechanism is not coaxial input and output, application It is not easy, and the transmission efficiency is the lowest, not exceeding 60%.
Due to the relative sliding friction transmission, the torsional rigidity of the worm gear reducer is slightly lower, and the transmission components are easily worn out, the working life is short, and the reducer is prone to temperature rise, so the allowable input speed is not high (2,000rpm), which is limited The use of worm gears is described.
