Couplings are commonly used parts in mechanical transmission and are now standard parts. When in use, you can choose a suitable coupling according to the national standard and the requirements of use.
Due to manufacturing and installation errors, deformation after load, and the influence of temperature changes, the two shafts connected by the coupling often cannot guarantee strict alignment, but there is a certain degree of relative displacement.Therefore, the cross coupling is selected for the connection between the reducer and the clutch. The cross coupling is composed of a half coupling with grooves on both ends and an intermediate 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.In order to reduce wear and friction, oil should be injected from the middle oil hole for lubrication.
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, pay attention to the working speed not greater than the specified value when selecting.
