They provide a positive, rigid connection between two shafts.
INSTALLATION AND REMOVAL INSTRUCTIONS FOR SHRINK DISCS IMPORTANT! Carefully Clean Shaft & Hub Bore & Keep Free of Any Lubricant Outer Collars Shrink Discs are supplied ready for installation. However, prior to tightening of locking screws it is necessary to remove wooden spacers located between outer collars, which are used during shipment of Shrink Discs.
SHRINK DISC COUPLINGS IFOR RIGID SHAFT CONNECTIONS- TRANSMIT TORQUES & BENDING MOMENTS- PERMIT AXIAL & ANGULAR TIMING RECOMMENDED SLEEVE DIMENSIONS FOR SHRINK DISC COUPLINGS USING SERIES 01 & SERIES 03 SHRINK DISC SIZE 140 & LARGER SHRINK DISC (PREFERABLY USE UNITS WITH INTEGRATED HUB STOP) REFER TO SHRINK DISC SPECIFICATION TABLE FOR SELECTION OF SHRINK DISC TO MEET YOUR TORQUE & SHAFT SIZE REQUIREMENTS. CONSULT WITH US IF A BENDING MOMENT HIGHER THAN 25% OF RATED TORQUE HAS TO BE TRANSMITTED.
3. Align the PLUNGERS with the tapered seats in the DRIVE PLATE. 5. Place BODY with the PLUNGERS face down on a solid surface. 4. Type C Clutch COUPLING: Insert mounting screws through the FLANGE PLATE into the tapped holes in the BODY π . Alternately tighten the screws until the flange plate is seated on the BODY. 6. Remove DETECTOR MOUNTING screws which will release the PLUNGER assemblies. Warning: The plunger assemblies are spring loaded and under tension.
Warning: Do not remove the detector mounting screws as they must retain the plunger assembly. 6. Place BODY with the PLUNGERS face down on a solid surface. 7. Remove DETECTOR MOUNTING screws which will release the PLUNGER assemblies. 6. Install the assembled clutch on the output shaft or flange of the INDEX DRIVE. 7. Prepare the DIAL, SPROCKET or DRIVEN MEMBER with a center hole and mounting holes to mate with the tapped holes in the DRIVE PLATE. (Refer to CAMCO assembly drawings.
