KL nylon slider coupling

KL nylon slider coupling is a kind of slider coupling, the structure isOldham couplingSimilar, the difference is that the middle block is a nylon block.The intermediate 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 coupling halves.

KL-type 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 ≤ 0mm, angular direction △α≤ 2'.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 rotation speed is very low, such as a ball mill.

The KL nylon slider coupling consists of two half couplings with grooves on the end faces and a middle disc with protruding teeth on both sides.Because the convex teeth can slide in the groove, the relative displacement between the two shafts during installation and operation can be compensated.Because the half-coupling and the intermediate disc form a moving pair and cannot rotate relative to each other, the angular velocity of the driving shaft and the driven shaft should be equal.However, when working with relative displacement between the two shafts, the middle disk will generate a large centrifugal force, which will increase the dynamic load and wear.Therefore, when selecting, pay attention that its working speed should not be greater than the specified value.
