Worm and Wheel Apparatus (30 : 1 ratio)

Product Description

Description of Worm and Wheel Apparatus (30 : 1 ratio)

Worm and Wheel Apparatus high quality example of an industry standard worm and wheel pairing is built on a substantial wall mounted bracket for vertical mounting. The Worm and Wheel Apparatus pair has a single start and a ratio of 30:1. The Worm and Wheel Apparatus are positioned a set distance apart to mesh correctly. Both parts run in bearings with the worm operating with an additional thrust bearing.

Attached to the end of the Worm and Wheel Apparatus is a pulley (EFFORT) of known effective diameter. This pulley helps exert the effort to raise a load. A cord is wrapped around its periphery and terminates in a load hanger for applying effort load. Attached to the front of the wheel is another pulley (LOAD) of known effective diameter. This pulley is used for the loading of the system. Again a cord is wrapped around its periphery and terminates in a load hanger. This hanger helps exert the loading onto the system via the weights set provided.

Experimental Capabilities of Worm and Wheel Apparatus (30 : 1 ratio)

1. Experimental determination of velocity ratio and comparison with calculated value
2. Determination of EFFORT with variation of load
3. Determination of friction with variation of load
4. Determination of efficiency with variation of load
5. Determination of limiting efficiency of the machine
