Oldham couplingAlso known as the metal slider coupling, the slider is in the shape of a circular ring and consists of a half coupling with grooves on two end faces and a middle disc with convex 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.
This kind of coupling material is generally made of 45 steel. The working surface needs to be heat treated to increase its hardness. In order to reduce friction and wear, oil should be injected from the oil hole of the intermediate plate for lubrication during use, because the half coupling and the intermediate plate are composed The moving pair cannot rotate relative to each other, so 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.
