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.
Specification:
1. Demonstration and student experimental unit on the set-up and principle of a worm gear 2. Bronze worm gear wheel 3. Steel worm 4. 2 Aluminium side drums 5. 2 sets of weights 6. Worm, worm gear wheel and pulleys ball bearing-mounted 7. Anodised aluminium base plateTechnical Data:
Side drum diameter
- on worm shaft: d=40mm - on worm gear wheel shaft: d=120mm
Worm drive
- axle base: 80mm - transmission ratio: 30:1 - modulus: m=4mm - number of gears: 1 - power transmission: 10
Weights on worm side
- 1x 50N - 1x 20N - 2x 10N - 1x 10N (suspended with balance mass)
Weights on worm gear wheel
- 1x 5N - 4x 2N - 1x 1N - 1x 0,5N - 1x 0,5N (suspended)
Base plate
- LxWxH: 250x200x12mm
