Name: SL cross - block coupling

Description: SL cross - block coupling consists of two semi-couplings with grooves on the end face and a middle plate with convex teeth. The relative displacement between the two axes can be compensated for when the convex tooth can slip in the groove.

Label: KL cross - block coupling WP E type (with telescopic flanged long) cross axle universal coupling SWP F type (large expansion single) universal coupler

Product details:

The SL cross - block coupling consists of two semi-couplings with grooves on the end face and a middle plate with convex teeth. The relative displacement between the two axes can be compensated for when the convex tooth can slip in the groove.

The material of this coupling part can be made of 45 steel, and the working surface needs to be treated with heat treatment to improve its hardness. Q275 steel can be used at lower requirements, and no heat treatment is required. In order to reduce friction and wear, lubricate the oil in the oil hole in the center plate. Because the semi-coupler and the center disk make up the mobile vice, the relative rotation cannot occur, so the angular velocity of the active shaft and the follower axis should be equal. But in the case of the relative displacement between the two axes, a large centrifugal force can be generated in the middle disk, which can increase the dynamic load and wear. Therefore, it should be noted that the working speed should not exceed the regulation value. This coupling is generally used for rotating speed n < 250r/min. The shaft has a large rigidity and no violent impact.

45 steel is available for the material of the coupling part of the second SL cross sliding block. The working surface needs to be treated with heat treatment to improve its hardness. Q275 steel can be used at lower requirements, and no heat treatment is required. In order to reduce friction and wear, lubricate the oil in the oil hole in the center plate. The sliding-block coupling is also known as a metal sliding block coupling, which is made of a circular ring, made of steel or abrasion resistant alloy, which is suitable for low speed and high transmission torque.
