chain tension by loosening the torque arm on the reducer, loosen set screws on shaft
bearings and slide pulley/sheave off shaft.
Spinner hangers use a variety of sheaves to drive the chamber drum and the
chamber spinner hangers. Roller conveyors use sheaves to drive rollers. They should be
periodically inspected.
Some spinner hangers use HTD sprockets and a HTD rubber belt to drive the
chamber drum. Inspect these sprockets periodically and replace if the teeth are worn,
chipped or cracked.
Always release the belt tension on any belt drive system before removing pulleys,
sheaves, or sprockets.
BELT DRIVE for SPINNER HANGERS and CONVEYORS
The proper alignment of the drive must be checked and maintained at all times. If
the drive is misaligned, the belts will rub on the sheaves/HTD sprockets causing reduced
belt and sheave/HTD sprocket life. Keep sheaves/HTD sprockets and belt free from dirt,
oil and grease. Rust nicks and burrs should be removed from the sheave/HTD sprocket
grooves and worn sheaves/HTD sprockets should be replaced. The locking devices on
the sheaves/HTD sprockets should be checked to assure and maintain proper tightness on
the shaft. Vibration or improper alignment could cause set screws, taperlock bushings or
locking caps to become loose. They should be checked and tightened periodically.
Urethane belts
are orange and round. They drive the spinner hanger mechanism
above the chamber. If conveyor is roller driven then each roller is driven by a urethane
belt. Replace belts when worn or cracked. Always release the belt tension before
removing the belt.
HTD rubber belts
are usually on Goff's heave spinner hanger machines. An
HTD rubber belt drives the chamber drum. Both urethane and HTD belts will be used on
heavy spinner hangers. Replace HTD rubber belts when the teeth are worn, chipped, or
cracked. Always release the belt tension before removing the belt.
