The invention relates to a rotary reducer, which comprises a rotary vertical shaft and a shell which are connected by a thrust upper bearing and a thrust lower bearing, wherein the head part of the rotary vertical shaft is connected with an internal spline on a secondary planet carrier through an external spline; the inside of the secondary planet carrier is provided with a secondary sun wheel engaged with three secondary planet wheels; one end of the secondary sun wheel is engaged with an internal gear of a primary planet carrier; a primary planet carrier gasket is arranged inside the primary planet carrier at a position close to the secondary sun wheel, and is provided with a primary sun wheel engaged with three primary planet wheels; an annular gear is arranged on the primary sun wheel; a shell cover plate is fixed at one end of the annular gear through six bolts; and the other end of the annular gear is connected with the shell through two positioning pins. The rotary reducer has the advantages of compact structure, little volume, light weight, large transmission ratio range, high transmission efficiency, stable operation and low noise.
Description
technical field [0001] The invention relates to a rotary reducer. Background technique [0002] At present, there are many kinds of reducers on the market. The structure includes oil distribution plate, plunger, cycloidal plate, housing, cylinder head, etc., mainly relying on three planetary gears on three crankshafts in the housing, and a sun gear connected to the motor shaft. Power synchronous rotation. The structure is complex, the processing precision is high, it is easy to produce various interferences, the vibration and noise are large, and the motion stability is poor. The transmission efficiency is low. The main reason for this is the short bearing life caused by the radial load of the planetary bearings. Contents of the invention [0003] The purpose of the present invention is to provide a rotary reducer, which solves the problems of high processing precision and complicated process, and further improves the product quality. [0004] The purpose of the presen...
