These hub - mountable aluminum gears are perfect for transferring motion from a motor or servo to a wheel or shaft. They have 48 teeth with a 32P gear pitch, an outer diameter of 1.563 inches, a 0.50 - inch bore, and use a 0.77 - inch hub pattern. Actobotics is a robotics building system featuring extruded aluminum channels, gears, precision shafts, and ball bearings. With two standardized hole patterns, almost all Actobotics components can be easily connected. The wide variety of components makes it possible to build complex electromechanical prototypes or finished projects. Dimensions: 48T at 32P teeth, 1.563 - inch OD, 0.50 - inch bore, 0.77 - inch hub pattern. Documents: SketchUp Part, Product Page (615190).
Using these gears is quite simple. First, make sure your motor or servo is ready. Then, mount the gear on the hub according to the 0.77 - inch hub pattern. Connect it to the wheel or shaft where you want to transmit the motion. When using, avoid applying excessive force that could damage the teeth. Keep the gears away from dirt and dust as much as possible. For maintenance, you can clean the gears gently with a soft cloth. If you notice any signs of wear, it might be time to replace the gear.
