B.Mounting the worm gear reducer
(See figure below)
Use 1/2'' - 13 SAE Grade 5 hex hd. Mounting Bolts and Lockwashers.
Make sure the mounting surface is thoroughly cleaned and free of any burrs of surface defects that would cause misalignment.
1. Check the fit for the Thru-Shaft by sliding the Thru-Shaft back and forth through the hub bore to make sure that it is a smooth slio-fit.
Check the fit of the Thru-Shaft with the key installed. Make sure that there is no binding around the keyway.
NOTE- Use Never-Seeze or a good synthetic high temperature grease on the shaft and key.
2. Install the gear reducer on the machine. Only hand tighten the mounting bolts at this time.
3. Install the Thru-Shaft and tighten the pillow block bearings.
4. Align the input Shaft to the Power Source. Use an adequate non backlash coupling. Make sure the Axial, Parallel and Angular Alignment is correct as per the couplings manufacturers' Alignment Specifications.
5. Shim under the motor as needed to assure correct alignment.
NOTE-If the Thru-Shaft deteremines the vertical position of the gear box, you may also have to shim under the gear box feet to accommodate for any vertical space to the mounting surface.
6. Tighten down mounting bolts. Torque to 60 Lb.Ft.
7. After the worm gear reducer has been in operation for a new hours, make sure the mounting bolts are tight and re-check alignment.
8. After the worm gear reducer has been in operation for 40 hours, make sure the mounting bolts are still tight. Tighten if necessary.
