The invention provides a hysteresis coupling. The hysteresis coupling comprises a first sleeve body, a second sleeve body arranged outside the first sleeve body in a sleeving mode, a bearing, a permanent magnet, a hysteresis ring and a friction ring, the bearing, the permanent magnet, the hysteresis ring and the friction ring are arranged between the first sleeve body and the second sleeve body, the first sleeve body comprises a ring plate and a cylinder body formed by extending outwards from the periphery of a central hole of the ring plate, the bearing is supported between the cylinder bodyand the second sleeve body, the permanent magnet, the friction ring and the hysteresis ring are arranged outside the cylinder body in a sleeving mode and clamped between the second sleeve body and thering plate, and the first sleeve body and the second sleeve body transmit torque through attraction force of the permanent magnet and the hysteresis ring and friction force between the permanent magnet and the hysteresis ring and the friction ring. The first sleeve body and the second sleeve body of the hysteresis coupling transmit the torque through the attraction force of the permanent magnet and the hysteresis ring and the friction force between the permanent magnet and the hysteresis ring and the friction ring, so that the permanent magnet and the hysteresis ring can slide relatively after the torque is limited, the permanent magnet and the hysteresis ring can output constant torque by limiting the torque, and the structure is simple.
Description
technical field [0001] The invention relates to a shaft coupling, in particular to a magnetic hysteresis coupling. Background technique [0002] In industrial production, in order to decelerate unpowered moving objects and avoid excessive impact force, dampers are usually used to block moving objects, and specific deceleration purposes are achieved according to different damping characteristics and damping forces. When the moving object is accelerated, an additional driving device is required to realize the acceleration and deceleration of the object with constant acceleration. In the transmission system, more stop positions are required. In order to achieve separate acceleration and deceleration, each stop position needs to be equipped with a set of independent damping devices and driving devices. In addition to the damper, the damping device also needs to be provided with the avoidance of the damping system. The device enables the objects to be continuously conveyed along...
