Compound cycloid reducer with retainer

Abstract

A compound cycloidal gear reducer with retainer relates to transmission, its fixed wheel is fixed on the inner wall of shell, the centre is equipped with round hole and the right side is equipped with compound cycloidal groove; the output disc is matched with the shell rotationally through bearings, left side is equipped with compound cycloidal groove or several equispaced circular holes; the bow-wave wheel is installed between the fixed wheel and the output disc, the left side is equipped with compound cycloidal groove and the right side is equipped with compound cycloidal groove or several equispaced circular hole; the opposite compound cycloidal groove or round holes are equipped with corresponding balls in itself, each ball is maintained by corresponding retainer; the eccentric sheave and input axle pass through the fixed wheel central round hole and are nested in the bow-wave wheel, and they are combined into input device through bearings. The eccentric sheave input axle rotates, each compound cycloid and ball form decreasing function and the output disc decelerates and outputs. The device has the characteristics of high efficiency, low noise, simple structure and etc. it can be widely used in various automated mechanical systems.

Description

technical field [0001] A compound cycloid reducer with a cage that can be used in automatic mechanical systems related to transmission. Background technique [0002] The existing cycloidal pin reducer is a reduction device in the form of a single-curve desktop arrangement, which has the advantages of high efficiency and large torque, but the structure is very complicated and the machining accuracy is high. Chinese patent CN861044574A changed the structure of the cycloid reducer and provided a gearless differential reducer, which theoretically has high transmission efficiency and simple structure, but this kind of device has the following defects: the manufacturing accuracy is very high, and it must be in a tight state , and must be placed radially and horizontally, and the principle must be realized only at low speeds, otherwise the balls will gradually displace, the reducer will lock itself, and the transmission will fail. In fact, there is no application significance. Co...
