弹性套柱销联轴器是利用一端套有弹性套(橡胶材料)的柱销，装在两半联轴器凸缘孔中，以实现两半联轴器的联接。它有结
构简单、制造容易、不用润滑、不会与金属硫化粘结，更换弹性套方便，不用移动半联轴器的特点，具有一定补偿两轴相对位移
和减震缓冲的特性。
弹性套柱销联轴器是依靠柱销组的锁紧力而产生与接触面的摩擦力矩，并压缩橡胶弹性套来传递扭矩:适用于安装底座刚性
好，对中精度较高、冲击载荷不大、对减震要求不高的中小功率轴系的传动。
Pin coupling with elastic sleeves is a connection mode that the Pin covered with elastic sleeve(made from rubber)in one
end is put into the flange holes of two half一couplings，which realize connecting the two half-couplings. It has the features of
simple structure，easy manufacture，and needless lubricating. It has no need of sticking with metal sulfuration，replaces the
elastic sleeves conveniently and does not move half-coupling. It possesses the characteristics of relative offset compensation
of the two shafts，Shock absorption and buffering.
Pin coupling with elastic sleeves generates frictional moment with contact surface depending on locking force of pin group,
and carry over torsional moment by compressing elastic sleeves of rubber. It is acceptable for the shafting drive of middle and
small transmission power，Which the rigidity of mount bottom is good，centering precision is higher，impulsive load is
moderate，and the ask for shock absorption is lower.
