Types of gear Types of bearings

Question

Accepted Answer

Types of gears include spur, helical, bevel, worm, and rack and pinion. Types of bearings include ball, roller, and sleeve bearings.

Spur gears have straight teeth and are used for low-speed applications.
Helical gears have angled teeth and are used for high-speed applications.
Bevel gears have angled teeth and are used for changing the direction of power transmission.
Worm gears have a screw-like thread and are used for high reduction ratios.
Rack and pinion gears are used for converting rotational motion into linear motion.
Ball bearings use balls to reduce friction and are used for high-speed applications.
Roller bearings use cylindrical rollers and are used for heavy loads and low-speed applications.
Sleeve bearings use a sliding motion and are used for low-speed and low-load applications.
