Abstract

The invention discloses a bevel gear transmission robot joint mechanism which comprises a front joint, a rear joint, a bevel gear transmission mechanism and a bevel gear transmission mechanism. The rear joint comprises a second motor, a second speed reducer and a bevel gear assembly, and the rear joint is connected to the tail end of the front joint through the first speed reducer; the second motor is located in the front joint; the second motor is connected to the second speed reducer through a bevel gear assembly, and an adjusting gasket is arranged between the bevel gear assembly and the rear joint. According to the mechanism, the number of transmission chain parts is small, the influence of accumulated errors on bevel gear meshing in the assembling process can be reduced, and the situations of noise, overload and the like are avoided.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a robot joint mechanism driven by bevel gears and a robot formed therefrom. Background technique [0002] There are generally two ways for the sixth-axis transmission structure in a six-axis load industrial robot. The first type is directly connected to the motor reducer and arranged at the end of the robot arm. The second motor is combined with a synchronous wheel, a synchronous belt, a bevel gear and a reducer to be connected for transmission. Among them, in the second way, the motor is placed in the J5 joint, which can reduce the weight of the robot’s sixth-axis transmission structure load, effectively reduce the robot’s load moment of inertia, and avoid performance waste. Under the same output torque, it can grab More weight, at the same time, the synchronous belt and bevel gear can be used to reduce the reduction ratio to obtain higher joint speed, so the second method is ...
