Question

State the worm and worm wheel machine is reversible or not. Give reason.​

Answer 1

Answer:

Unlike with ordinary gear trains, the direction of transmission (input shaft vs output shaft) is not reversible when using large reduction ratios. This is due to the greater friction involved between the worm and worm-wheel, and is especially prevalent when a single start (one spiral) worm is used.

Explanation:

Some machine can produce in product both in straight and reverse direction (raw material to product, product to raw material).

There are only few of this type of machines.
