TM 123: Spur Gear Lifting Apparatus

Print Ask to this Articlel

Spur Gear Lifting Apparatus

Product Details


Technical Description 
 
The mechanism demonstrates the relationship between the ratio of the number of teeth on spur gears and the transmission ratio of gears. With straightforward experiments, the torque conversion in gear wheel pairs and the efficiency of a gear unit are investigated.
The model is intended for wall mounting. The well-structured instructional material outlines the technological fundamentals and provides a step-by-step guide through the experiments.

Learning Objectives / Experiments

Learning the key variables and correlations of a spur gear:
- Velocity ratios of spur gears
- Gear with intermediate wheel or two-stage gearing
- Influence of friction on transmission
- Determining efficiency
 
Features
 
* Mode of operation and layout of toothed gearing
