By coupling a custom manufacturer Uliflex today to tell everyone coupling which performance is required. 1. Can be moved. Coupling of movable refers to compensate the relative displacement of two rotating components. Because be connected component between the manufacture and installation error, the operation factors such as temperature and deformation under load, so the movable sexual have certain requirements. Movable property compensation or relief because of the relative displacement between the rotary components caused by the additional load. 2. Buffer. In starting or working load change often load, coupling vibration and needs to have a buffer, the elastic element, to reduce the damage to the prime mover and work machine. 3. For safe, reliable, and have sufficient strength and service life. 4. Requirements of simple structure, easy installation and maintenance. Above is the performance of the coupling is required, hope to be of help.
