弹性柱销联轴器的特点 
●本联轴器已列为国家标准GB5014-85，适用于各种机械联接两同轴线的传动轴，通常用于动频繁的高低速运动。工作温度为-20 ～+80℃；传递公称扭矩为40～20000N.m。 
●弹性柱销联轴器具有较大结构简单、合理，维修方便、两面对称可互换，寿命长，允许较大的轴向窜动，具有缓冲、减震、耐磨等性能。 
●轴孔型式有圆柱形(Y)、圆锥形(Z)和短圆柱形(J)。轴孔和键槽按国家标准GB3852-83《联轴器轴柱和键槽形式及尺寸》的规定加工。半联轴器采用精密铸造，铸铁HT20-40、铸钢ZG35Ⅱ，轴孔和键槽采用拉制成型，柱销采用MC尼龙b制成。

●弹性柱销联轴器是利用若干非金属弹性材料制成的柱销，置于两半联轴器凸缘孔中，通过柱销实现两半联轴器联接，该联轴器结构简单，容易制造，装拆更换弹性元件比较方便，不用移动两半联轴器。弹性元件（柱销）的材料一般选用尼龙，有微量补偿两轴线偏移能力，弹性件工作时受剪切，工作可靠性极差，仅适用于要求很低的中速传动轴系，不适用于工作可靠性要求较高的工况。

The characteristics of the elastic pin coupling

The coupling has been listed as the national standard gb5014-85, which is suitable for the transmission shaft of two coaxial lines of mechanical connection, usually used for high and low speed movement. Working temperature is 20 ~ + 80 ℃; The transfer torque is 40 ~ 20000n. m.

Low elastic dowel pin shaft coupling with bigger has simple and reasonable structure, convenient maintenance, bilateral symmetry, interchangeable, long life, allows larger axial channeling, buffer, shock absorption, wear-resisting performance, etc.

The axial hole type has cylindrical (Y), conical (Z) and short cylindrical (J). The shaft hole and keyway are machined according to the national standard gb3852-83 "coupling shaft and keyway form and dimension". Half coupling with precision casting, cast iron HT20-40, cast steel ZG35 Ⅱ, axle hole and the keyway USES the drawing forming, dowel pin with MC nylon made from b.

Low elastic dowel pin shaft coupling is the use of a number of non-metallic elastic material dowel pin, put in two and a half coupling flange hole, achieved by column pin half coupling, the coupling structure is simple, easy to manufacture, replace the elastic element installation is more convenient, need not move two half couplings. Elastic element (dowel pin) nylon material selection in general, there are two axis offset trace compensation ability, flexible work under shear, work reliability is poor and is only applicable to medium speed transmission shafting with low requirements, the operation condition of the high reliability requirement does not apply to work.
