AI Technical Summary
Technical Problem
The existing cycloid reducer has problems such as large size, high consumables, heavy weight, and high cost due to the installation of bearings on the input and output discs.
Method used
A cage and roller structure is used to replace the traditional cross roller bearing. The input disc and output disc are in contact with the pinion housing, and pinions are arranged inside the pinion housing to achieve power transmission, reducing consumables and weight.
Benefits of technology
It effectively reduces the volume and weight of the cycloid reducer, reduces costs, and maintains the stability of power transmission.

Abstract
The utility model discloses a cycloidal speed reducer, which belongs to the field of robot joints and comprises a pin wheel housing, an input disc and an output disc which are respectively and rotatably mounted at two ends of the pin wheel housing, a cycloidal disc which rotates in the pin wheel housing and is meshed with the pin wheel housing, and an eccentric shaft which sequentially penetrates through the input disc and the cycloidal disc and is connected with the output disc, the eccentric shaft is rotationally connected with the input disc, the cycloid disc and the output disc, and the input disc and the output disc are each provided with a first bearing making contact with the pin wheel housing. The first bearing comprises a retainer, containing grooves formed in the retainer in an annular array mode and pin rollers rotationally installed in the containing grooves. According to the cycloidal speed reducer, the retainers and the pin rollers are arranged between the input disc and the pin wheel housing and between the output disc and the pin wheel housing to replace traditional crossed roller bearings, the overall length and diameter of the cycloidal speed reducer can be effectively reduced, and therefore the cost of the cycloidal speed reducer can be effectively reduced while the size, consumables and weight of the cycloidal speed reducer are reduced.
