Product Summary
These three pairs of gears are driven by stepper motors or servo motors to make PASCO Structures move. These three pairs enable three different gear ratios (1:1, 2:1, 4:1) with the same shaft separation, making it easy to change gear ratios.
The gears are secured on the motor shaft or PASCO Structures axles using the included anti-backlash screws.
The 60T and 72T gears have the hole and threaded hole features that allow a Structures I-beam to be attached directly to the gear.
