Abstract

The invention discloses a mechanical joint and a robot arm comprising the mechanical joint. The mechanical joint comprises a hollow shaft, a first gear, a plurality of motors, a plurality of second gears, an encoder and a digital processing and driving unit. The first gear is fixed to the hollow shaft. The motors surround the hollow shaft and are respectively provided with a rotating shaft. The second gears are fixed to the rotating shafts and meshed with the first gear. The motors drive the second gears to rotate the hollow shaft. The encoder is arranged at the side, opposite to the corresponding second gear, of one motor. A signal of the encoder is transmitted back to the digital processing and driving unit to drive the motors. According to the mechanical joint, as the motors drive the hollow shaft to rotate in cooperation with the gears, output torsion of the hollow shaft can be effectively increased, and magnitude of deceleration is lowered. A user can adjust the number of the motors according to different requirements to change torsion and rotating speed of the hollow shaft of the mechanical joint. Due to the fact that the encoder and the digital processing and driving unit are located on the same plane, space allocation can be effectively saved.

Description

technical field [0001] The invention relates to a mechanical joint, in particular to a mechanical joint applied to a mechanical arm. Background technique [0002] The robot arm (robotarm) is an automatic control device that imitates the function of the human arm and can complete various tasks. This robot system is multi-jointed and allows movement in a plane or three-dimensional space or using linear displacement. Structurally, it is composed of a mechanical body, a controller, a servo mechanism and a sensor, and a certain specified action is set by a program according to the operation requirements. For example, the servo mechanism can be used to drive the mobile robot arm to the position, and then perform the action of the clamp, and accurately feed back to the programmable logic controller. [0003] Most of the robotic arms are mainly aimed at completing the movements of the wrist and hand. After inputting the operation sequence into the controller, it can repeat countles...
