Question

6. State velocity ratio of gear pulley block with single threaded worm and with double
threaded worm.​

Answer 1

Answer:

Explanation:

The velocity ratio of gear pulley block with single threaded worm and with double threaded worm is $20:1$ .

The worm geared pulley block formula is  the ratio of the product of the diameter of the effort wheel and the number of teeth on the worm wheel to the radius of the pulley, and is written as $i=(d\times T)\div R$, or $Velocity Ratio = (Diameter of effort wheel \times Number of teeth on worm wheel)/Radius of pulley$.

As a result, the gear ratio is the "size of the worm wheel - to - $1$" regardless of the worm's size (reasonable engineering constraints excepted). A $20$tooth worm wheel slows the speed by the ration of $20:1$ when used with a single start worm.

Answer 2

Answer:

velocity ratio of gear pully 20:1

Explanation:

regardless of the worm's size (sensible engineering limits notwithstanding), the gear ratio is the "size of the worm wheel - to - 1". Given a single start worm, as a 20 tooth worm wheel reduces the speed by the ratio of 20:1
