The present invention discloses a method for modifying the tooth profile of a friction plate in a liquid-viscous speed regulating clutch, comprising the following steps: step 1, radial modification of external teeth: when radial deformation occurs to the external teeth of the friction plate, tooth top modification is adopted; three coordinate points after modification are obtained by the intersection of the involute equation and the tooth top circle equation and the deformation amount, the three points are connected by a hyperbola to obtain a modification curve, and radial repair of the external teeth is performed according to the modification curve; step 2, radial modification of internal teeth: when radial deformation occurs to the internal teeth of the friction plate, a radial displacement compensation mechanism is provided to compensate for the radial deformation, and radial modification of the internal teeth of the friction plate is performed; step 3, axial modification of internal teeth: when axial deformation occurs to the internal teeth of the friction plate, a displacement correction method is adopted to increase the tooth thickness for repair. The present invention takes into account the modification of deformation of the friction plate under different working conditions, improves the tooth contact stress and extrusion stress, and solves the problem that the friction plate teeth can still transmit normally after deformation under different working conditions.

This invention relates to a joint module integrating a torque sensor and a harmonic reducer, belonging to the field of robot joint module technology. The joint module includes a harmonic reducer and a hollow shaft, with the harmonic reducer and hollow shaft coaxially fixedly assembled. A brake housing is coaxially mounted behind the harmonic reducer, and an electromagnetic brake and friction plates are installed inside the brake housing. This invention eliminates couplings, additional connecting flanges, and other transitional connecting parts, highly integrating the torque sensor and harmonic reducer. The frameless motor is directly connected to the wave generator, and the controller is built-in. This reduces the overall axial length by 22%, the radial length by 25%, and the weight by 15%-30%, significantly improving space utilization. It is more suitable for collaborative robots, service robots, and other equipment with stringent requirements for lightweighting and miniaturization, solving the technical defects of large joint modules and large space occupation in existing technologies.
