Cycloidal lantern gear reducer

Abstract

The invention relates to a cycloidal lantern gear reducer. A rolling bearing is arranged between an output disc and a pin gear housing of the cycloidal lantern gear reducer and comprises a bearing inner ring, a bearing outer ring and a rolling body clamped between the bearing inner ring and the bearing outer ring, wherein the rolling body comprises a plurality of cylindrical rollers and spherical rollers; the cylindrical rollers and the spherical rollers are arranged along the same circumference alternately; retaining frames are arranged between adjacent cylindrical rollers and spherical rollers; the shaft axes of the cylindrical rollers are parallel to the shaft axes of the shaft axis of the bearing; the diameter of the spherical rollers is smaller than that of the cylindrical rollers; and the diameter of the spherical rollers is greater than the height of the cylindrical rollers. The cycloidal lantern gear reducer of the invention is compact, small in volume and low in cost.

Description

technical field

[0001] The invention relates to a cycloidal pinwheel reducer. Background technique

[0002] Most of the domestic cycloid reducers are large in size, low in transmission accuracy, and large in hysteresis, and generally can only be used in equipment with low requirements, such as metallurgical and mining machinery, lifting equipment, etc. One of the influencing factors is that the end support bearings used in the cycloid reducer are difficult to meet the actual needs. There are two types of end support bearings on common miniaturized cycloid reducers:

[0003] One is the angular contact ball bearing, which can be changed to a non-standard thin-walled bearing in order to reduce the volume, and the inner ring of the angular contact ball bearing is removed for the reducer with a smaller volume, and the roller table is directly used as the gland and the output on the plate. However, through the transformation of the above structure, the bearing has become a non-...
