Abstract

The invention discloses a multi-disc permanent magnet eddy current speed regulation device capable of reducing axial load. The multi-disc permanent magnet eddy current speed regulation device comprises an equipment shell, an input end, an output end, a magnetic disc synchronization device and a driving device; the input end comprises an input shaft, a first conductor disc assembly, a second conductor disc assembly and a connecting sleeve; the output end comprises an output shaft, a first magnetic disk assembly and a second magnetic disk assembly; the magnetic disk synchronizing device comprises a central disk, a first synchronizing rack, a second synchronizing rack and a synchronizing gear; the driving device comprises an actuator sleeve, a sleeve supporting bearing, a driving seat and a magnetic disk connecting rod; a spring is further included and installed between the second magnetic disc and the third magnetic disc. A multi-disc series structure arrangement form is adopted, so thatthe space occupied by equipment in the radial direction can be reduced; due to the application of the technology, the driving mechanism of speed regulation equipment can provide very small driving force to meet the driving requirement of the whole equipment, and the driving structure of the original equipment technology is small, exquisite, simple and easy to arrange through the optimization of the technology.

Description

technical field [0001] The invention belongs to the technical field of transmission equipment, in particular to a multi-disc permanent magnet eddy current speed regulating device which reduces axial load. Background technique [0002] The permanent magnet eddy current transmission technology of the disk structure includes a conductor disk and a permanent disk. The magnetic force generated by the eddy current in the conductor disk interacts with the permanent disk to realize energy transmission. The transmission state is related to the air gap between the conductor disk and the permanent disk, and the transmission torque and rotational speed can be changed by adjusting the air gap between the conductor disk and the permanent disk through the adjusting device. Due to the characteristics of the magnetic steel, a large axial force will be generated between the conductor disk and the disk. This axial force will cause the drive bearing to bear a large axial load. The magnitude an...
