5-2 Mounting Connector
- When mounting connector, do not give an impact or excessive axial load to the shaft. Otherwise, the bearing may be damaged or
collar may come off.
- shrinkage-fit is recommended.
(1) When Using a Coupling
The alignment accuracy (A, B, X) in figure 5-6 should be no greater than that shown in Table 5-1.
(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.
- Select a sprocket or gear pitch diameter that is at least three times 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 5-7)
(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 5-8)
- When using multiple V belts, use a matched set having the same length.
