1 | g e a r s & i t " s t y p e s. 1. 1 advantages and limitations of gear drive over chain and belt drives. 1. 2 definition of gear: classification of gears, spur gear. 3. 1 advantages & disadvantages of spur gears: helical gear. 4. 2 types of helical gears: bevel gear. 5. 1 types of bevel gears: worm gear. 2 | g e a r s & i t " s t y p e s. Gears are toothed wheels used for transmitting motion and power from one shaft to another when they are not too far apart and when a constant velocity ratio is desired. In comparison with belt, chain and friction drives, gear drives are more compact, can operate at high speeds and can be used where precise timing is required. Also gear drives are used when large power is to be transmitted.
