To install a gear-driven encoder (Figure 3-12), follow these steps:
1. Install the driver gear on the line shaft. Tighten the set-screws.
2. Position and install the encoder so that it is square with the driver gear.
3. Raise or lower the encoder to tighten the belt against the driver gear. (Ensure that the two sides of the
belt are not pressed together under the wheel.) Due to the low torque required, the belt should not be
extremely tight.
At least 7-9 teeth should engage in the line shaft driver gear.
It may be necessary to fabricate an adjustable bracket to
connect the encoder base to the parent machine frame.
