Speed regulation type magnetic coupler with completely separated power source and load and small axial space

Abstract

The invention provides a speed regulation type magnetic coupler with a completely separated power source and load and a small axial space, and the magnetic coupler comprises a first transmission ringand a second transmission ring; good conductors are uniformly distributed on the first transmission ring, good conductor end rings for completely short-circuiting the good conductors are arranged at two ends of the good conductors, and the first transmission ring uniformly distributed with the good conductors is a conductor ring; permanent magnets are uniformly distributed on the second transmission ring, and the second transmission ring on which the permanent magnets are uniformly distributed is a permanent magnet ring; the conductor ring and the permanent magnet ring are not in mechanical contact in the axial direction and the radial direction and are air gaps; the first transmission ring is in rigid connection with the power source through a first bearing seat, the power source and thebearing seat are installed on the linear moving platform, and the linear moving platform is installed on the bottom plate. The second transmission ring is in rigid connection with a load through a second bearing seat, and the second bearing seat is installed on the bottom plate and keeps coaxial and concentric with the first bearing seat. The speed regulation type magnetic coupler has the advantages of being short in axial speed regulation length, high in speed regulation reliability, good in vibration isolation effect and the like.

Description

technical field [0001] The invention relates to the technology of a speed-regulating magnetic coupler, in particular to a speed-regulating magnetic coupler with a power source completely separated from a load and with a small axial space. Background technique [0002] The existing speed-regulating magnetic coupler generally has the following defects: [0003] (1) There are connecting bearings, and the vibration isolation effect is poor: the existing speed-adjustable magnetic couplers (such as ZL201210441925.0, a cage-shaped rotor magnetic coupler with adjustable speed, ZL201310340277.4, US6682430B2, US2002 / 0132671A1, etc.) are To ensure the axial fixation of the input end (power source) and the output end (load), the connection bearing (also called embedded bearing) is generally used to connect the input end and the load end together. Since the connection bearing is rigidly connected, the The use of connecting bearings greatly weakens the vibration isolation effect of the c...
