Description

Cam Clutch for Backstop and Overrunning Applications (BR)

Production introduction

USING THE BR SERIES PACKAGE TYPE CAM CLUTCH
Similar to previous types, the package type Cam Clutch is designed into a ball bearing cassette that makes installation with a torque arm and/or coupling fast and easy. The package type Cam Clutch is grease lubricated.
Installation and Usage
1. We recommend using shaft tolerances of h6 or h7 for Cam Clutch installation.
2. Use a ISO R773 (DIN 6885.1) parallel key. Make sure that the key does not move in the keyway. A loose key will damage the Cam Clutch.
3. When installing the Cam Clutch over a shaft, please follow the procedure outlined below. Never hit the clutch with a steel hammer or apply unnecessary impact loads.
1) Verify the Cam Clutch direction of rotation. The arrow on the inner race shows the free running (cam disengaged) direction. Make sure that the direction of cam engagement matches the intended application.
2) Tap the inner race lightly with a soft hammer moving around the race circumference so the Cam Clutch moves slowly and uniformly onto the end of the shaft. Make sure that the outer race does not become dislodged.
3) Place an end plate over the inner race and use the mounting bolts to pull the Cam Clutch onto the shaft as shown in the diagram at right.
4) Tighten the end plate securely to make sure that the Cam Clutch cannot move on the shaft.
4. If you using a torque arm, make sure that the bolts used to mount the torque arm have a tensile strength of 10.9 or greater, and tighten them securely.
5. Set a 2mm clearance between the torque arm and the torque arm stopper. If the torque arm is rigidly mounted, it will be applying a load to the Cam Clutch which can eventually damage it.
6. Install an appropriate coupling if there is a chance that the shaft will elongate from thermal expansion as encountered in some exhaust fan auxiliary drive system applications.
7. If thrust loads are encountered, install a thrust bearing which will prevent those thrust loads from being transferred to the Cam Clutch.
8. The Cam Clutch is pre-packed with grease before shipment and is ready for installation and operation. Refer to page 80 for lubrication guidelines.

Mounting example:

Installation and Usage:

1. If you are installing the outer race first, check the precision of the fit. The tolerances for outer race mounting are shown in the tables at right. Verify that the correct tolerances can be obtained. Out of spec installation could damage the Cam Clutch.
2. To lubricate the Cam Clutch, apply lubricant at the outer circumference of the inner race (see installation diagram). Avoid over lubrication, as it will cause the Cam Clutch to generate excessive heat.
3. When using the Cam Clutch at a reduction gearbox, make sure that oil from the gearbox cannot enter the Cam Clutch. Service life can be significantly shortened if the Cam Clutch comes in contact with gear oils that contain viscosity enhancing additives. Refer to page 80 for lubrication guidelines.
4. When installing a cover or seal support over the outer race, use bolts with a tensile rating of 10.9 or greater. Use a sealing agent or packing material between the mating services to prevent leakage.
