Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] combine figure 1 The robot wrist drive mechanism specifically includes a load plate 2 connected to an external drive, a housing 1, a first deceleration unit 3, and a second deceleration unit 4. The load plate 2 is rotatably arranged on the housing 1, and the first The deceleration unit 3 and the second deceleration unit 4 are both arranged in the housing 1 , wherein the output part of the first deceleration unit 3 is connected to the load plate 2 in transmission, and the output part of the second deceleration unit 4 is fixedly connected to the housing 1 .

[0014] Due to the design requirement for a higher transmission ratio and a relatively compact space structure, the first reduction unit 3 and the second reduction unit 4 in this embodiment are both harmonic gear reducers.

[0015] The harmonic gear reducer includes a rigid wheel with an inner...

Abstract

The invention relates to the field of robots, in particular to a robot wrist driving mechanism. The robot wrist driving mechanism particularly comprises a load plate, a shell, a first speed reducing unit and a second speed reducing unit, wherein the load plate is in drive connection with the outside. The load plate is rotationally arranged on the shell, both the first speed reducing unit and the second speed reducing unit are arranged in the shell, the output part of the first speed reducing unit is in drive connection with the load plate, and the output part of the second speed reducing unit is fixedly connected with the shell. Two harmonic gear reducers are used for respectively driving two-freedom-degree motion of the wrist of a robot, and the robot wrist driving mechanism is small and compact in structure and high in drive stability.

Description

technical field [0001] The invention relates to the field of robots, in particular to a robot wrist driving mechanism. Background technique [0002] Industrial robots are used more widely in various fields in today's manufacturing industry. In industrial robots, the design of the wrist is a very important indicator. It not only needs to meet the performance requirements of the robot, but also hopes to be compact, so The design of the robot wrist has always been based on the principle of compact structure. The existing robot wrist movements are usually realized through a relatively complicated transmission mechanism, and the reliability is low. Contents of the invention [0003] The purpose of the present invention is to provide a robot wrist drive mechanism with small and compact structure and high transmission reliability, which is specifically realized by the following technical solutions: [0004] A driving mechanism for a robot wrist, specifically comprising a load p...
