Description
本实用新型属于联轴器技术领域，具体涉及一种用于长轴泵的防振动型联轴结构。The utility model belongs to the technical field of couplings, in particular to an anti-vibration type coupling structure for a long-shaft pump.
联轴器是用来联接不同机构中的两根轴使之共同旋转以传递扭矩的机械零件，一般动力机大都借助联轴器与工作机相联接。现有的市场上联轴器一般通过橡胶垫等弹性材料进行振动缓冲，但是橡胶垫的减震效果有限，对于一些震动更加强烈的器材，联轴器连接处的两侧传动位移不能及时补偿，缓冲减震效果不佳，联轴器容易受到较大冲击，导致联轴器内部部件容易损坏。Couplings are mechanical parts used to connect two shafts in different mechanisms to rotate together to transmit torque. Generally, power machines are mostly connected to working machines by means of couplings. Couplings in the existing market generally use elastic materials such as rubber pads for vibration buffering, but the shock absorption effect of rubber pads is limited. For some equipment with stronger vibration, the transmission displacement on both sides of the coupling joint cannot be compensated in time. The effect of buffering and shock absorption is not good, and the coupling is easily subjected to large shocks, resulting in easy damage to the internal components of the coupling.
