Worm and Wheel Apparatus
Description
Worm and Wheel Apparatus
Technical Description:
The permits investigations of the torques and the efficiency of the gear unit. The transmission ratio of the gear can be determined. Students learn the basic terminology of gearing in a simple manner: numbers of teeth; modulus; reference circle and axle base. The worm gear wheel and worm are ball bearing-mounted. The forces are generated by the sets of weights and can be quickly and easily varied. The model is intended for wall mounting. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
