Installation Instructions New shrink discs are supplied ready for installation. rior to tightening the locking screws, remove the spacers (used to protect the inner ring during shipment) from between the outer collars. Figure 1 shows a cutaway drawing of a typical shrink disc. Non-Contact Area IMOTANT! Carefully Clean riven Shaft & Hollow Shaft Bore & Keep Free of Any Lubricant Outer Collars 4. With shrink disc in its proper position on the gear drive hollow shaft, use a torque wrench and tighten all locking screws ¼ turn at a time, progressing around the flange in either direction until the specified torque is achieved on all locking screws. imum outer collar gap variation is listed in Table 1. Locking screw tightening torques are listed in Table 2. emoval emove the drive from the shaft using the following procedure: 1. Loosen locking screws ½ turn at a time progressing around the flange in either direction until the shrink disc is loose on the hollow shaft. o not completely remove the locking screws. On vertical drives, support driven shaft before loosening the shrink disc fasteners and removing keeper plate/ driven shaft fastener. The keeper plate has a tapped hole for a larger fastener to assist in shaft removal if needed. 2. Suspend gear drive assembly. isconnect tie rod or drive mounting and slide gear drive off of driven shaft. Clean hollow shaft O outside of shrink disc and slide shrink disc off of hollow shaft. riven Shaft Hollow Shaft FIGE 1 - TYICAL SHINK disc Metric Hex Head Locking Screws IN 931, Class 10.9 Inner ing IMOTANT: Never tighten the shrink disc locking screws unless the driven shaft is inserted into the gear drive hollow shaft with full engagement under the shrink disc. Without the driven shaft in place, plastic deformation of the hollow shaft and shrink disc inner ring can occur. Install using the following procedure: 1. Clean hollow shaft O and shrink disc inner ring bore. Lightly lubricate hollow shaft O with light mineral oil. Slide shrink disc onto shaft to its proper position (Figure 2, age 2). Be certain that inner edge of shrink disc inner ring is not hung up on a shaft radius. Hand tighten three or four locking screws equally spaced around flange while maintaining outer collars parallel. Hand tighten remaining fasteners. 2. Carefully clean hollow shaft bore under shrink disc and driven shaft O of all lubricants with solvent before assembly of gear drive to driven shaft (Figure 1). Any traces of lubricant left on the driven shaft or hollow shaft bore under the shrink disc will significantly reduce the torque transmission capacity of the shrink disc. 3. Suspend and slide the gear drive into its proper position on the driven shaft (Figure 3, age 2). Install keeper plate assembly (when used) and tighten fasteners to the torque specified in Table 3 (Inch) or Table 4 (Metric). einstallation In clean operating conditions, shrink discs can be reused without cleaning and relubricating the inner ring, outer ring tapers and locking screws. Shrink discs that require cleaning should be thoroughly cleaned. The tapers of the inner ring, tapers of the outer collars and the locking screw threads and head washer faces should be lubricated with molybdenum disulfide grease before reinstallation. amaged O-rings should be replaced.
