联轴器的改进和优选制浆造纸厂大量使用了泵类设备。将泵轴和电动机连接起来的联轴器,通常都是采用弹性圈柱销联轴器。由于这种联轴器具有补偿两轴的位移、缓和冲击、吸收振动、结构简单等优点,所以应用很广泛。但是这种联轴器加工要求较高,制造困难,特别是弹性圈很易损坏,柱销 Improvement and Optimization of Couplings Pulp and paper mills make extensive use of pumping equipment. The coupling that connects the pump shaft to the motor is usually a snap-fit ​​coupling. Because this kind of coupling has the advantages of compensating the displacement of two axes, absorbing shock, absorbing vibration and simple structure, it is widely used. However, this coupling machining requirements are higher, manufacturing difficulties, especially the elastic ring is very easy to damage, pin
