Common
5-2 Mounting Connected Equipment
-When mounting connected equipment, do not apply impact or excessive axial load to the shaft. The bearing could be damaged, or
the collar could come off.
-Shrinkage fit is recommend.
(1) When using a coupling
The alignment accuracy (A, B, X) in figure 5-1 should be no greater than that shown in Table 5-3.
(2) When using chains, sprockets, or gears
- When using a chain, attach so that the chain tension angle is perpendicular to the shaft.
- Refer to the chain catalog or other reference for chain tension.
- The pitch circle of the sprocket and gear shall be more than three times of the shaft diameter.
- The working load point of the sprocket or gear should go from the center of the shaft to this product. (See figure 5-2)
(3) When using a V belt
- Over-tightening the V belt will damage the shaft and bearing. Refer to the V belt catalog or other reference for V belt tension.
- The parallelism, eccentricity β of the two pulleys should be within 20´. (See figure 5-3)
- When using multiple V belts, use a matched set having the same circumferential length.
