Background

The coupling is a device for connecting two shafts or a shaft and a rotating part, rotating together in the process of transmitting motion and power and not being separated under normal conditions. Sometimes, the coupling is used as a safety device to prevent the coupled machine parts from bearing excessive load and plays the role of overload protection, the coupling is divided into a fixed rigid coupling and an elastic coupling, the rigid coupling has the advantages of simple structure and easy manufacture, and the elastic coupling is divided into a movable coupling and an elastic element elastic coupling.

A coupling is disclosed in CN201827259U, which solves the problem that the conventional coupling is composed of two separate parts connected together, that is, a coupling connecting a driving shaft and a driven shaft, and a connecting portion located between the two couplings. When the motor drives the driving shaft and the driven shaft to rotate at a high speed, the fastening screw for fixing falls off, causing equipment damage. Meanwhile, as the axes of the couplers are manually closed, the phenomena of unbalanced centrifugal inertia force, centrifugal inertia coupling force and dynamic deflection (vibration mode) are generated during operation, the unbalanced phenomenon inevitably causes vibration of a shaft system, so that the normal work and the service life of a machine are influenced, but the problems that the gap of the existing coupler is inconvenient to adjust when in use, the existing coupler cannot be adjusted when connecting pieces with different sizes are inserted, the couplers with different sizes are required to be reused for operation, the use effect is poor, the cost is increased, the use feeling is reduced, and the operation is difficult when the coupler is manually operated and installed are still not solved, and therefore the self-adaptive gap tooth-shaped coupler is provided.
