Euler device of cycloid speed reducer

Abstract

An Euler device of a cycloid speed reducer comprises an Euler element and a plurality of roller retainers. The Euler element comprises a ring body and a plurality of convex bodies. The ring body is provided with an inner ring surface and an outer ring surface opposite to the inner ring surface. The convex bodies are arranged on the outer ring surface of the ring body at intervals in a surroundingmode, and each convex body is provided with an arranging end surface opposite to the outer ring surface. The roller retainers are detachably arranged on the convex bodies respectively. Each roller retainer includes a retainer piece corresponding to the arranging end surface of the corresponding convex body and two clamping pieces which are spaced from each other, connected with the retainer pieceand arranged on the corresponding convex body in a matched and clamped mode. Each retainer piece is provided with two holding hook parts which extend outwards to the two opposite sides of the corresponding convex body and correspond to the outer ring surface respectively.

Description

technical field [0001] The invention relates to a cycloidal reducer, in particular to an Oldham component of the cycloidal reducer. Background technique [0002] refer to figure 1 , an existing Odan element 81 used for a cycloid reducer is sleeved on an input shaft 82 and connected between a cycloid wheel 83 and a flange 84, and the Odan element 81, the cycloid wheel 83 and the flange 84 are provided with a plurality of rollers 85, but the above-mentioned elements are all located in a casing 86. Because the structural design of the Odan element 81, the cycloidal wheel 83 and the flange 84 cannot resist the radial disengagement of the roller 85, it must pass through the casing 86 at the corresponding Odan element 81. A limit ring 87 is set to resist the radial movement of the roller 85. In this way, not only the casing 86 must be correspondingly increased in size to accommodate the limit ring 87, but also the Oldham element 81, It is difficult to assemble the cycloidal whe...

Problems solved by technology

The Oldham element 91 includes a ring body 911, four convex bodies 912 formed around the outer ring surface of the ring body 911 at intervals, and four pairs of limiters formed on the convex body 912 opposite to the end of the ring body respectively. The position hook 913, the limit hook 913 of the Oldham element 91 can resist the radial separation and movement of the roller 95. In this way, the problem of adding the limit ring 87 to the aforementioned cycloidal reducer can be solved. However, when the Odan component 91 is in the grinding process, the ring body 911 cooperates with each limit hook 913 to easily interfere with the grinding cam operation, causing each convex body 912 and the ring body 911 and the corresponding limit The surface of the connecting groove of the bit hook 913 forms a grinding step difference, and the grinding step difference formed by the Odan component 91 will cause the wear of the roller 95. Wan's special machine is used for the grinding process to overcome the above-mentioned grinding level difference problem
