对轮柱销式联轴器

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.

对轮联轴器惯性主轴线与旋转轴线之间重心位置偏心量的可能值是平方和方根值而决定的，主要由两半联轴器和联接螺栓组成，对轮联轴器轴套孔装配前，镗削切割和键槽的修整联轴器端面和其它表面的加工等。半联轴器的轴套孔有圆锥孔和圆柱孔两种形式，圆锥孔比圆柱孔在工艺特性上有较多的特点，圆锥形轴套孔容易获得相配合部件之间的同心。

对轮联轴器在工作过程中，并且会带来燃油消耗空气污染等后果，由于承受咬入冲击动载荷，使得联轴器受到峰值转矩，联轴器承载能力下降，并在短时间内失效，从而直接影响其正常工作，其中的较薄弱环节进行替换或维修是重要和实用的。联轴器两轴相对半径变位要求较好，找耦合同心度为0.2~0.6mm，存在很大困难。如果在驾驶过程中螺栓松动，泵装置的振动和噪音可能会变大。
