KL nylon slider coupling

KL nylon slider coupling is a kind of slider coupling, the structure isOldham coupling相似，不同之处在于中间块为尼龙块，利用中间滑块在其两侧半联轴器端面的相应径向槽内滑动，以实现两半联轴器联接。

KL尼龙滑块联轴器适用于传递转矩较小的场合，具有   补偿两轴相对偏移量、减震和缓冲的性能，工作温度为-20℃-70℃，许用转速为1500-10000r/min，传递转矩为16-5000N.m 许用补偿量：轴向△ x=1~2mm , 径向△ y ≤ 0.2mm ,角向△α≤ 40 ′。该联轴器噪声大,效率低,磨损快,一般尽量不选用,只有转速很低的场合,如球磨机等才选用。

The KL nylon slider coupling is composed of two half couplings $, L with grooves on the end faces and a middle plate with convex teeth on both sides". Because the convex teeth can slide in the surface groove, it can be compensated. The relative radial and axial displacement between the two shafts during installation and operation. The two halves of the coupling and the intermediate disc form a moving pair, which cannot rotate relative to each other. Therefore, the angular velocity and angular displacement of the main and driven shafts are equal. But when the main and the driven When the axis of the shaft has a radial displacement, the speed and acceleration of each point are different in magnitude and direction, which generates a large inertial force, which increases the dynamic load, friction loss and wear.
