 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.
WH oldham coupling oldham coupling with the characteristics of oldham coupling structure similar, the difference is between the cross slide block is square block, using the slider in the middle on both sides of the half coupling end of the corresponding radial sliding groove, in order to realize the two and a half coupling. The coupling noise is large, low efficiency, wear fast, generally not selected, only the low speed of the occasion, such as the ball mill. Allowable compensation: axial delta x=1~ 2mm, radial delta y is less than 0.2mm, and the Angle is less than 40
