Description

Technical Field

[0001] The utility model relates to a T-shaped magnetic coupling box. Background Art

[0002] The coupling is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. The traditional T-type or L-type transmission coupling relies on mechanical gears for meshing motion, which is a rigid motion. When the load on the load end fluctuates over a large range, it will cause instantaneous or continuous overload to the power equipment on the drive end. Long-term operation will cause large fluctuations in the input current of the power equipment and high heat generation, which seriously affects the service life of the power equipment and greatly increases the maintenance cost of the power equipment, especially the equipment with higher costs.
