Non-Standard End-of-Shaft Mounting Procedure
For mounting on a non-standard end-of-shaft, perform the following steps (
see Figure 13
).
The pulse wheel is designed to use one spacer washer for a motor shaft length of
0.400 ± 0.010 inch. If the motor shaft is a different length, please refer to Section
2.2.6 for axial position adjustment.
Select the appropriate bolt to go through the center hole of the pulse wheel and into the center tapped motor shaft.
Place pulse wheel shaft recess over the end of the motor shaft.
Insert center mounting bolt through pulse wheel center into motor shaft. Tighten so that the pulse wheel sits completely
flat against the motor shaft. Tighten to specified torque value for bolt.
This securely holds the pulse wheel onto the motor shaft. However, some
measure of pulse wheel anti-rotation should be taken.
Drill through the anti-rotation holes of the pulse wheel into the motor shaft.
Insert a roll pin sized to snugly fit the pulse wheel anti-rotation hole, through the pulse wheel, and into the motor shaft.
The pulse wheel should be seated flat against the motor shaft. The wheel should not appear
to wobble if the motor shaft is turned by hand. Excessive wobble can damage the pulse wheel and
sensor modules.
