SCREW CONVEYOR DRIVE

The TL screw conveyor drive consists of a component gear drive (which equals the TR gear drive plus the gear drive adaptor and minus the torque arm assembly), a drive shaft kit and a trough end adaptor kit.
To convert a TR to a TL, a TR/TL conversion kit, along with a drive shaft kit and tround end adaptor kit is required.
The TL drive shaft kit contains a removable shaft, locknut, lockwasher and key. TL drive shafts have a tapered output end to avoid binding.
The trough end adaptor kit contains the trough end adaptor and packing gland assembly.  Dorris trough ends are available.

TROUGH END ADAPTORS

trough_end_adaptors

All dimensions are typical.
All trough end adaptors can use either the standard or high performance packing gland assembly.
C69 adaptor uses 1-1/2 inch drive shaft; C924 adaptor uses 2 through 3-716 inch drive shaft.

MOTOR MOUNTS (2MM - 90 LBS.)

Motor brackets are shown in the intermediate position.  The brackets can be raised or lowered 6 1/4 inches to the high or low position by moving to the next set of mounting holes.
