Description

Technical Field

[0002] A coupling with an elastic deformation compensation structure is usually called an elastic coupling. An elastic coupling uses the elastic deformation of the elastic element in the coupling to compensate for the relative displacement of the two shafts. Its working principle is: when there is a relative displacement between the two shafts, the elastic element will undergo elastic deformation, thereby absorbing and compensating for this displacement, ensuring smooth transmission of power. Elastic couplings are widely used in various transmission systems that require compensation for relative displacement of shafts, such as ships, wind turbines and other high-speed and high-power application environments, as well as precision transmissions, servo transmissions and shaft angle detection devices.
