The contorq unit has been developed to provide an accurate controlled torque for reeling cable and suitable for specialized application like CRD. The contorq itself is a slipping interface using UHMW polyethylene discs incorporated in a gear wheel of a contorq unit and gear is mounted on worm shaft of NUR worm gear box.
The pinion drives the gear wheel of contorq unit should be mounted on a output shaft of flange mounted geared motor.
The contorq is a continuosly slipping device consists of a series of discs held in position circumferentially and radially and pressing against friction, which are connected alternatively to a hub on drive shaft and to a gear, which runs freely on bearings mounted on hub.
The pressure of the friction disc on the faces is applied by spring pressure, which is adjustable. the whole assembly runs in synthetic oil ( servomesh SP – 460 ) which not only lubricates the gear and bearings but also act as a coolant.
Torque is transmitted, when slip occurs between gear and hub and this torque can be adjusted to suit requirement of drive.
Adjustment of torque of contorq unit is by castellated nut accessed by removing flanged mounted geared motor. Rotate the nut in clock wise direction to increase torque and in anti clock wise to decrease the torque.
