Embodiment Construction

[0015] According to the problems existing in the output mechanism of the traditional planetary gear reducer, the present invention proposes an output device of the planetary gear reducer, which is characterized in that the output device includes two end faces, a floating ring arranged between the two end faces and One end is quartered and connected to the floating ring, and the other end is crossed and connected to two end faces with four connecting arms. The two end faces can be integrated with the externally connected parts, a through hole passes between the two end faces and the floating ring, the central axis of the two end faces, the floating ring and the through hole is the same axis, and passes through the two end faces The shape of the through hole of the floating ring and the floating ring is a circle, a square, etc., and the two end faces, the floating ring and the connecting arm all have connection terminals, which are used for the connection between the two end face...

Abstract

The invention relates to a planetary gear reducer. The planetary gear reducer comprises an output device, and is characterized in that the output device comprises two end faces, a floating ring and afour-branch connection arm, wherein the floating ring is arranged between the two end faces, one end of the four-branch connection arm is connected with the floating ring in a quadrate mode, and the other end of the four-branch connection arm is connected with the two end faces in a crossing mode. The connection arm can be a hinged rigid component and can be a fixedly connected elastic component.By adopting the planetary gear reducer, for example, a central wheel is fixed to a machine case, and the output device is arranged between a planetary gear and an output shaft, the output device can compensate the circumferential translating movement of the planetary gear around the central wheel axis, the rotational motion of the planetary gear around the self axis is transmitted to the output shaft to be output. The planetary gear reducer is simple in structure, less in part, small in return difference, low in manufacturing cost and good in user experience.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a planetary gear reducer. Background technique [0002] The involute planetary gear reducer belongs to the K-H-V planetary transmission and is a new type of mechanical transmission. The transmission device is composed of a center wheel (center wheel K), a planet carrier (ie eccentric shaft H) and a special output mechanism V. It has a large single-stage transmission ratio, compact structure, small size, light weight, convenient processing and reliable operation. , long service life, transmission efficiency and other characteristics, used in petroleum, chemical, agricultural machinery, light industry mining, construction machinery and other industries. Many published books on mechanical transmission technology have also elaborated on this type of transmission device. Generally, in terms of its transmission mechanism, it can be roughly divided into: pin shaft type,...
