WORM & WORMGEAR ADJUSTMENT
Excessive backlash may develop after
using system for some time. We have
incorporated a built in backlash
adjustment block to keep backlash at a
minimum.
Please review drawings shown for
more detailed information.
To adjust system:
1. Slightly loosen locking bolts to hand
tight.
2. Use a
3/16”
Allen wrench to turn
adjustment bolt.
3. One full turn of the adjustment bolt
will move adjustment block 0.010 of an
inch.
4. Clockwise rotation of the adjustment
bolt will move the adjustment block
down, moving the worm closer to the
worm gear and removing backlash.
5. Counter clockwise rotation of the
adjustment bolt will move the
adjustment block up, moving the worm
away from the worm gear and creating
more backlash.
6. Adjustments should be made with
the motor running. Use the motor drive
sound as gauge for friction between
worm and worm gear.
Note:
To much friction may cause gear
binding in rarely used sections of the
worm gear. Some finesse maybe
required.
7. Tighten locking bolts and test sys-
tem. Listen for motor running sound for
smooth system operation and minimal
backlash.
