柱销联轴器轴头间距

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。

弹性柱销联轴器是一种结构简单制造容易，无需润滑，装拆弹性柱销便捷的传动基础件，利用两个带法兰孔的半联和置于起重的非金属弹性柱销来传递扭矩，适用于中低速和中低扭矩场合。

弹性柱销齿式联轴器采用非金属弹性柱销和两个带齿形半联以及一个外圈的齿形套环设计，利用非金属弹性的变形来传递扭矩同时缓冲减震，补偿角向位移。

弹性套柱销联轴器设计简单巧妙，适用性较广的联轴器，利用带弹性套的柱销联接两个带销孔的半联，实现扭矩传递的同时兼具较大的角向补偿，同时减震缓冲性能良好，可以用在速度较快的场合，无需润滑，销套更换便捷。

The pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement. The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions. The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, Pin and bush couplings has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
