Desai Electronics Project Engineer Mechanical Interview Questions and Answers

Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings use balls to reduce friction between two surfaces (e.g. deep groove ball bearings)

• Roller bearings use cylindrical rollers to support heavy loads (e.g. tapered roller bearings)

• Plain bearings have a simple design with no rolling elements (e.g. bushings)

• Fluid bearings use a fluid film to support rotating shafts (e.g.

Types of gears include spur gears, helical gears, bevel gears, worm gears, rack and pinion gears, and planetary gears.

• Spur gears have straight teeth and are the simplest type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

• Worm gears have a screw-like appearance and are used for high torque applications.

• Rack a...read more
