The present application discloses a highly integrated high-performance robot joint unit, belonging to the technical field of robot apparatuses. When a reducer of an existing robot joint is in overload working state, it causes joint parts such as a reducer gear to be damaged, and a meshing tooth surface of each tooth of the reducer is unevenly worn. In the present application, when a torque transmitted to a gear ring by an output end of a motor rotor or a reducer assembly is greater than a friction torque between the gear ring and a motor base, the gear ring of the reducer assembly is driven by the output end of the motor rotor or the reducer assembly to overcome the friction torque generated under the action of a friction force generator, such that the gear ring and the motor base rotate relatively, thus realizing the frictional sliding between the reducer assembly and the motor base, limiting the torque borne by the reducer assembly, and preventing the reducer from being damaged due to the large torque from the motor end or the output end of the joint unit.

A spring mechanism is connected between the input shaft and the intermediate drive element for aligning the intermediate drive element and the input shaft in a driving configuration in which rotation of the input shaft at a torque below a predetermined threshold is transmitted to the output shaft via the jammer element, but in which torque above the predetermined threshold moves the input shaft rotationally relative to the intermediate drive element against the force of the spring mechanism so as to disengage that jammer elements from driving engagement with the output shaft.

The spacer ring is located between and contacts the arc-shaped protrusions of the external transmission device and the arc-shaped protrusions of the internal transmission device. When torque between the external transmission device and the internal transmission device is greater than a predetermined torque, one or more of the arc-shaped protrusions of the external transmission device or the arc-shaped protrusions of the internal transmission device deform and the external transmission device rotationally slips relative to the internal transmission device.
