5-2) Coupling Installation
• When installing a coupling, do not impact or apply excessive thrust load to the shaft ; otherwise, the bearing may be
damaged or collar may be left.
• Thermal shrinking is the recommended installation method.
• when a sprocket, gear or pulley is coupled with the variator, use within the range of the allowable radial and axial load
defined on our catalog.
(1) When Using a Coupling
The accuracy of the dimensions (A, B, and X) shown in Fig.5 should be within the tolerance shown in Table 4.
(2) When Using a Chain Sprocket and Gear
• The chain tension angle should be perpendicular to the shaft.
• Refer to the chain catalog for the chain tension.
• Select sprockets and gears whose pitch diameter are three times the shaft diameter or greater.
• Install sprocket and gears so that their point of load application will be closer to the variator side with respect to the
length of the shaft. (Fig.6)
(3) When Using a V-belt
• Excessive V-belt tension will damage the shaft and bearing. Refer to the V-belt catalog for proper tension.
• The parallelism and eccentricity (ß) between two pulleys should be within 20'. (Fig.7)
• Use a matched set with the same circumferential length when more than one belt is to be installed.
• Install V-pulley so that their point of load application will be closer to the variator side with respect to the length of the
shaft.
