What are power transmission devices?
Power transmission devices are very commonly used to transmit power from one shaft to another. Belts, chains and gears are used for this purpose. When the distance between the shafts is large, belts or ropes are used and for intermediate distance chains can be used. … Gear drive is used for short distances.

Types of Gears
- Spur Gear: The spur gear has a helix angle of 0°.
- Worm Gear: Worm gears are found in right angle gearboxes. They “turn a corner.”
- Helical Gear: This is an angle toothed gear. …
- Bevel Gear: Bevel gears tend to have a lower ratio and run at a higher efficiency than worm gears.
