Abstract

The invention discloses a bearing reducer center wheel shell in the field of machine transmission. The bearing reducer center wheel shell comprises a cylindrical side plate, the upper portion of the inner wall of the side plate stretches inward to form a ring-shaped upper end plate, the lower portion of the outer wall of the side plate stretches outward to form a ring-shaped lower end plate, the top of the upper end plate is provided with a plurality of installation holes in the peripheral direction, the inner side wall of the upper end plate is provided with a plurality of vertical slots evenly formed in the peripheral direction, the tops of the slots are connected with the top of the upper end plate, the bottoms of the slots are connected with the bottom of the upper end plate, the section outline of each slot is in an arc shape, smooth transition is formed between every two adjacent slots, and the section outline of the side wall of the upper end plate is a ring-shaped track in a curtate epicycloid shape. By means of the bearing reducer center wheel shell, a bearing reducer has the advantages of being small in radial load, high in transmission ratio, uniform in load distribution, low in noise, low in abrasion, long in service life and high in carrying capacity.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a center wheel housing of a bearing reducer. Background technique [0002] At present, there are two main types of reducers used in the field of robotics, one is the Rotate Vector reducer (RV reducer) of Japan's Nabtesco Teijin Seiki Co., Ltd., and the other is the harmonic reducer of Japan's Harmonic Drive. They almost monopolize The world's robot reducer. In the robot joints, because the RV reducer has higher rigidity and rotation accuracy, the RV reducer is generally placed on the base, the boom, the shoulder and other heavy load positions, and the harmonic reducer is placed on the forearm, arm, etc. wrist or hand. [0003] The transmission of the harmonic reducer is through the radial elastic deformation of the thin-walled flexible gear to realize the speed conversion and power transmission. The load-carrying capacity and transmission stiffness of the thin-walled flex...
