Coupling

Abstract

The invention belongs to the technical field of mechanical transmission, and particularly relates to a coupling. The coupling comprises a left half coupling, a right half coupling, magnets, air bags, windings, sliding blocks and a groove, wherein the left half coupling is fixedly connected with a driven shaft, the right half coupling is fixedly connected with a driving shaft, a circular groove is formed in the end face, close to the left half coupling, of the right half coupling, a hollow shaft connected with the left half coupling is arranged in the groove, the groups of magnets are uniformly embedded in the inner circumference of the side wall of the groove, mounting holes are formed in the positions, corresponding to the magnets, of the outer edge of the hollow shaft, the air bags are fixedly connected to the bottoms of the mounting holes, the windings formed by winding copper wires are arranged on the peripheries of the air bags, clamping blocks are arranged at the ends, far away from the bottoms of the mounting holes, of the air bags, and the sliding blocks are connected in the clamping blocks in a sliding mode. According to the coupling, magnetic induction lines of the winding cutting magnets generate currents for heating, so that the air bags expand to push the sliding blocks to abut against the side wall of the groove, power is smoothly transferred from the driving shaft to the driven shaft through the friction force between the sliding blocks and the groove, so that the service life of a prime mover is prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, in particular to a coupling. Background technique [0002] Coupling refers to a device that connects two shafts or shafts and rotating parts, and rotates together during the transmission of motion and power, and does not disengage under normal conditions. A mechanical component used to firmly couple the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. It is often composed of two halves, respectively connected by keys or tight fits, fastened at the ends of the two shafts, and then connected by some means. [0003] At present, some equipment will generate a large impact force when transmitting torque, and rigid couplings cannot be used. Therefore, such equipment usually uses rubber belts as couplings to transmit torque, but such couplings have a short service life and are difficult to maintain. Frequently, it cannot meet...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, the rubber belt is used as a coupling to transmit torque, but this type of coupling has a short service life and frequent maintenance, and cannot meet the transmission requirements of large impact forces. At the same time, the current flexible coupling is used in When the equipment is blocked, it will cause fatal damage to the prime mover. A coupling proposed by the invention
