弹性柱销齿式联轴器是利用若干非金属材料制成的柱销，置于两半联轴器与外环内表面之间的对合孔中，通过柱销传递转矩实现两半联轴器联接，该联轴

器具有以下特点： 

●（1）传递转矩大，在相同转矩时回转直径大多数比齿式联轴器小，体积小，质量轻，可部分代替齿式联轴器。

●（2）与齿式联轴器相比，结构简单，组成零件较少，制造较方便，不用齿轮加工机床。

●（3）维修方便，寿命较长，拆下档板即可更换尼龙销。 

●（4）尼龙柱销为自润材料，不需润滑，不仅节省润滑油，而且净化工作环境。

●（5）减振动能差，噪声较大。 弹性柱销齿式联轴器具有一定补偿两轴相对偏移的性能，适用于中等和较大功率传动，不适用于对减振有一定要求和噪声需要严加控制的工作部位。

Elastic dowel pin coupling is the use of a number of non-metallic materials of the dowel pin, placed in two and a half coupling between inner surface and outer ring the involution of the hole, achieved by column pin transfer torque half coupling, the coupling

The appliance has the following characteristics:

(1) the transmission torque is large, and in the same torque, most of the rotating diameters are smaller than the tooth couplings, small in size and light in weight, which can be partially replaced by the dental coupling.

(2) compared with the tooth type couplings, the structure is simple, with fewer components and more convenient manufacturing.

(3) the maintenance is convenient, the life is longer, remove the plate can replace the nylon pin.

(4) nylon pin is self-run material, not lubrication, not only saves the lubricating oil, but also purifies the working environment.

(5) the vibration can be poor and noisy. Elastic dowel pin type coupling with certain compensation performance of the two axes relative offset, suitable for medium and high power drive, does not apply to have a certain request for vibration damping and noise must be kept under strict control of the work.
