Problems solved by technology

Since the RV reducer has extremely high requirements on the processing and assembly precision of parts, and the processing technology of parts such as pin gear housing and cycloidal wheel is poor, it is difficult to achieve efficient processing on existing general-purpose machine tools, and it is necessary to develop expensive special-purpose machine tools. thus higher manufacturing costs
In addition, the cycloidal pinwheel transmission is very sensitive to the eccentricity error of the cycloidal wheel, and the eccentricity error has a great influence on its contact, force and transmission accuracy

Embodiment

[0033] A reducer that can be used to connect to the joints of industrial robots, including a first-stage planetary gear mechanism and an involute planetary gear mechanism with few teeth difference. The first-stage planetary gear mechanism is composed of a central gear and a planetary gear, and the involute few teeth The differential planetary gear mechanism consists of an eccentric shaft, an external gear and an internal gear housing (including internal teeth). The power is input from the central gear, and transmitted to the outer gear through the eccentric shaft fixedly connected with the planetary gear. Driven by the eccentric shaft fixedly connected with the planetary gear, the outer gear swings in a plane under the force of the inner gear housing, which means it orbits the inner gear. The axis of the gear housing revolves, and then rotates around its own axis, and outputs the rotation motion of the external gear through the W mechanism.

Abstract

The invention provides a 2K-V speed reducer. The speed reducer comprises a primary planetary gear mechanism and an involute small tooth difference gear mechanism. A planetary mechanism is composed of a central gear and a planetary gear. The involute small tooth difference gear mechanism is composed of an eccentric shaft, an outer gear and an inner gear casing. Under the drive of the eccentric shaft of the involute small tooth difference gear mechanism, the outer gear performs planar motion by the action of the inner gear casing, rotates around own axis reversely while revolving around the axis of the inner gear casing and outputs own rotation through a planet carrier. The speed reducer can be used for being connected with joint portions of industrial robots.

Description

technical field [0001] The invention relates to a precision reducer, in particular to a reducer which can be connected to the joint part of an industrial robot. Background technique [0002] The reducer widely used in the joints of industrial robots is mainly composed of a first-stage planetary gear mechanism and a first-stage cycloidal pinwheel mechanism. And there is a tendency to gradually replace harmonic gear transmission. The reducer using one-stage planetary gear transmission and one-stage cycloidal pinwheel transmission is called RV reducer. Since the RV reducer has extremely high requirements on the processing and assembly precision of parts, and the processing technology of parts such as pin gear housing and cycloid wheel is poor, it is difficult to achieve efficient processing on existing general-purpose machine tools, and it is necessary to develop expensive special-purpose machine tools. Therefore, the manufacturing cost is higher. In addition, the cycloidal ...
