Servomotor-speed reduction integrated mechanism

Abstract

The invention discloses a servomotor-speed reduction integrated mechanism, which comprises a servomotor output shaft, planetary gears, a planetary gear disk, an upper gearbox cover and a lower gearbox cover, a shaft end gear is arranged on one end of the servomotor output shaft, and is engaged with the planetary gears, the center of each planetary gear is provided with a through hole, the planetary gears are fitted on planetary gear-fixing pins, the planetary gear-fixing pins run through the through holes and are fixed on the planetary gear disk, the other end of the planetary gear disk is an output shaft, an output shaft bearing is arranged on the output shaft, the lower gearbox cover is provided with a through hole, the output shaft runs through the through hole, an output shaft oil seal is arranged in the through hole, an inner gear ring is arranged around the planetary gears, and is engaged with the planetary gears, an input end bearing is mounted on the inner side of the upper gearbox cover, the inner gear ring is fixed on the inner wall of the lower gearbox cover by positioning pins, and the upper gearbox cover is fixedly connected with the lower gearbox cover through big bolts.

Description

technical field [0001] The invention relates to a reduction mechanism of a servo motor. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. Mechanisms play the role of matching speed and transmitting torque, and are widely used in modern machinery. The reducer is generally used for low-speed and high-torque transmission equipment, and the power of the electric motor, internal combustion engine or other high-speed operation is passed through the input shaft of the reducer. The gear with a small number of teeth meshes with the large gear on the output shaft to achieve the purpose of deceleration. An ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the ...

Problems solved by technology

[0004] However, the existing structural settings have the following two disadvantages of connection methods: 1) Due to the limited space of the clamping method, the locking screws are very small, so it is easy to slip when locking; 2) The keyway connection is objective due to the processing The cumulative error that exists causes the two ends of the connection to be misaligned
