Abstract

The invention relates to the technical field of mechanical transmission, and concretely relates to a disc type self-adjusting air gap permanent magnet flexible connection device. The device comprises: a first connecting shaft on which an induction disc is fixed; a second connecting shaft, wherein a permanent magnet disc is mounted on the second connecting shaft in an axial sliding manner; a limiting piece located on the second connecting shaft and located between the permanent magnet disc and the induction disc; a tensile elastic piece located on the second connecting shaft, wherein the free end of the tensile elastic piece is connected with the permanent magnet disc; and a centrifugal driving assembly located on the side, away from the induction disc, of the permanent magnet disc and comprising a guide rod, a centrifugal block, an elastic piece and a linkage block, wherein the guide rod is fixed to the second connecting shaft, the centrifugal block is slidably arranged on the guide rod in a sleeving mode, the linkage block is fixed to the permanent magnet disc and connected with the centrifugal block through an inclined surface or a surconical face, and the inclined surface or the conical surface is suitable for driving the linkage block to move in the direction away from the guide rod when the centrifugal block moves outwards in the radial direction. By adopting the scheme, the air gap can be automatically adjusted during starting, the structure is simple, the weight is light, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a disc-type self-adjusting air gap permanent magnet soft connection device. Background technique [0002] In order to solve the problem of excessive starting torque, a hydraulic coupling or soft starter is generally added between the motor and the load. The hydraulic coupling can delay the start-up time of the motor and slow down the start-up impact, but it has the problems of low efficiency, oil leakage and large space occupation; the conventional soft starter can realize the soft start of the system, but all require a special control system, Complex structure and inconvenient maintenance. [0003] For this reason, a permanent magnetic coupler specially designed to solve the above problems has been developed on the market. Existing permanent magnetic couplers mainly include disc permanent magnetic couplers and barrel permanent magnetic couplers. There is a cer...
