Abstract
The invention relates to a mechanical arm joint which comprises a hollow shaft and a brake assembly, a motor assembly, a harmonic reducer assembly, an output assembly, a housing assembly, and a measurement assembly which are disposed outside the hollow shaft, the measurement assembly includes a torque sensor, and the torque sensor is provided inside the housing assembly and fixed to the housing assembly, the torque sensor is fixed to the harmonic reducer assembly at the same time. The torque sensor is provided in the joint, so as to ensure that the torque sensor is not damaged by external impacts during assembling and maintaining of the joint and the mechanical arm. The power cables and signal cables are connected to the circuit board at the right end of the joint from the side of the joint instead of through the joint center hole, so that the torque sensor cable and other cables in the joint are arranged separately, therefore the signal of the torque sensor does not interfere with the signal in other cables, and it is beneficial to the torque sensor signal transmission due to the length of cable is shorter, and the joint structure is more compact because of the diameter of joint center hole becomes smaller due to the number of the cables passed through the joint center hole decreases.
