A new device to limit or prevent damage to thickeners, clarifiers, mixers, elevators, hoists, conveyors, or other process or materials-handling systems where large torques are encountered, has been introduced by the Delroyd Worm Gear Division of Transamerica Delaval Inc.
Designated the TQ-8 torque monitor and controller, it is available on any Delroyd worm gear speed reducer. The new unit is adaptable to single or multiple reduction reducers with vertical or horizontal configuration, shafted or shaft mounted, so long as the reducer is driven through an induction motor.
A transducer pickup is installed on the motor mount, the monitor/controller itself being up to 200 feet away. Shaft speed is converted to slip (which varies linearly with torque in the 10-115 percent load range), and is compensated for temperature and line voltage variations with solid state circuits.
