Jiangsu KL nylon slider coupling

KL nylon slider coupling is a kind of slider coupling, the structure isOldham couplingSimilarity, the difference is that the middle block is a nylon block, and the middle sliding block is used to slide in the corresponding radial grooves on the end faces of the coupling halves on both sides to realize the coupling of the two halves.

KL nylon slider coupling is suitable for occasions where the transmission torque is small. It has the performance of compensating the relative offset of the two shafts, damping and buffering. The working temperature is -20℃-70℃, and the allowable speed is 1500-10000r. /min, the transmission torque is 16-5000N.m. Allowable compensation amount: axial △ x=1~2mm, radial △ y ≤ 0.2mm, angular △α≤ 40'.The coupling is noisy, low in efficiency, and wears quickly. Generally, it is not used as much as possible. It is only used when the speed is very low, such as a ball mill.

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.
