Problems solved by technology

This kind of work not only leads to low production efficiency of robot manufacturers, but also brings the following problems:
In the robot manufacturing site, the operation of adding lubricating grease to the cavity of the RV reducer is extremely cumbersome, and it is easy to bring metal dust or powder into the cavity of the reducer, causing internal grease pollution, thereby reducing the service life of the reducer
Moreover, the amount of grease added and the sealing of grease are also highly technically difficult.

Abstract

The invention discloses a RV reducer with a novel structure. The RV reducer with the novel structure comprises a RV reducer shell, a first level planetary reduction mechanism and a second level cycloid reduction mechanism are arranged in the RV reducer shell, a planetary gear of the first level planetary reduction mechanism is meshed with a center gear on one end of an input shaft, the input shaft and an output shaft of a servo motor are the same shaft, and the center gear is manufactured and made at the tail end of the output end of the servo motor; one end of the RV reducer shell is connected with a servo motor shell through a flange, the output shaft of the servo motor and the flange are sealed through a skeleton sealing ring, and an output end cover is arranged on the other end of the RV reducer shell. The RV reducer with the novel structure is reasonable in structure, the precision is high, and the noise is low.

Description

technical field [0001] The invention relates to an RV speed reducer. Background technique [0002] The RV reducer has the characteristics of high precision, small size and high load torque, and is widely used in the field of industrial robots. figure 1 It is a simplified structural diagram of a traditional RV reducer. Both sides are open structures, and both sides need to be sealed when in use. One end of the input shaft is the central gear, which meshes with the planetary gear of the RV reducer to form a first-stage planetary reduction mechanism; the other end of the input shaft is connected to the servo motor. Cycloid wheel, needle roller and pin gear housing constitute the second stage cycloid reduction mechanism. figure 2 It is a schematic diagram of the permanent magnet brushless AC servo motor, which is widely used in the transmission parts of industrial robots. Together with the RV reducer, the servo motor constitutes the joint part of the industrial robot. [00...
