Abstract

The invention discloses a stepped coaxial transmission mechanism for a robot. The stepped coaxial transmission mechanism for the robot comprises a first-stage stepped transmission mechanism, wherein a first servo motor, a second servo motor and a third servo motor are arranged at the upper end of the first-stage stepped transmission mechanism. The tail ends of output shafts of the first servo motor, the second servo motor and the third servo motor are connected with a first synchronous belt wheel, a second synchronous belt wheel and a third synchronous belt wheel correspondingly, a first synchronous belt, a second synchronous belt and a third synchronous belt are connected onto the first synchronous belt wheel, the second synchronous belt wheel and the third synchronous belt wheel correspondingly. The lower end of the first-stage stepped transmission mechanism is connected with a second-stage stepped transmission mechanism, and the end, away from the first-stage stepped transmission mechanism, of the second-stage stepped transmission mechanism is connected with a third-stage stepped transmission mechanism. According to the stepped coaxial transmission mechanism for the robot, the problems that the internal space of the robot is small, a large number of assemblies exist, and much transmission is needed are solved, the internal structure of the robot is optimized to the maximum extent, and the equipment size is reduced.

Description

technical field [0001] The invention relates to the technical field related to single-arm transmission, in particular to a stepped coaxial transmission mechanism for a robot. Background technique [0002] A stepped coaxial transmission mechanism for a robot optimizes the inner space of the robot, reduces the volume of the robot, and effectively reduces the volume of the robot without reducing the working area. According to the different working environment, the synchronous belt with different pitches can be replaced to obtain a larger working area. In the field of application of manipulators on the market today, a servo motor is generally used to drive a section of the manipulator, and the volume is relatively large. The present invention adopts the stepped coaxial transmission mode, integrates the motor on the first-stage stepped coaxial transmission mechanism, and transmits the power to the various mechanical arms through the transmission shaft and the synchronous belt, t...
