Belt type hysteresis coupler

Abstract

The invention relates to a mechanical transmission different-axle coupler, in particularly to a belt type hysteresis coupler. According to the invention, the magnetic field induction is used to send an external drive source to an output shaft for completing torque output. The belt type hysteresis coupler comprises an output shaft, a heat-dissipating shell arranged on the output shaft and a permanent magnet disk arranged in the heat-dissipating shell, wherein one end of the heat-dissipating shell is provided with a belt pulley, the belt pulley is connected with a drive source through a belt, and the drive source drives the heat-dissipating shell to rotate through the belt and the belt pulley; magnetic steel is arranged on the inner wall of the other end of the heat-dissipating shell; the permanent magnetic disk is arranged on the output shaft of the inner cavity of the heat-dissipating shell, the permanent magnet disk is installed corresponding to the magnetic steel, an adjusting nut is arranged between the permanent magnet disk and the magnetic steel, and the distance between the permanent magnet disk and the magnetic steel can be adjusted through the adjustment nut so as to change the induction strength of a magnetic field. The mechanical transmission different-axle coupler can meet the requirement of constant output of torque and is applied to different use requirements; and meanwhile, the coupler has greatly improved service life, and the purpose of saving energy and reducing the cost is achieved.

Description

technical field [0001] The invention relates to a mechanical transmission different-shaft coupling device, in particular to a belt-type hysteresis coupling. Background technique [0002] The hysteresis coupling is a new type of coupling that connects the prime mover and the working machine through the magnetic force of the permanent magnet. It does not need a direct mechanical connection, but uses the interaction between rare earth permanent magnets, and the magnetic field can penetrate A certain space distance and the characteristics of the material are used to transmit mechanical energy. It is widely used in mobile winding machinery and equipment, which can effectively ensure the synchronization of mobile equipment and ensure a constant output torque. The commonly used hysteresis coupler is connected to the drive source with an elastic cushion, which is directly driven by the drive motor. According to the output torque of the coupler, a suitable drive motor is equipped. Th...

Problems solved by technology

Due to the use of elastic buffer pads, the buffer pads are prone to deformation and damage after long-term use. Once damaged, the coupling transmission cannot effectively buffer and easily cause damage to the hysteresis coupling.
