Tata Chemicals Quality Inspector Interview Questions and Answers

Bearings are mechanical components that reduce friction between moving parts.

• Bearings are used in machines to support rotating shafts and reduce friction.

• There are several types of bearings including ball bearings, roller bearings, and plain bearings.

• Ball bearings use balls to reduce friction and are commonly used in applications such as skateboards and bicycles.

• Roller bearings use cylindrical rollers to reduce frictio...read more

Gears are mechanical components that transmit power and motion between rotating shafts. There are various types of gears.

• Gears are used to transmit power and motion between rotating shafts

• They are made up of teeth that mesh with each other to transfer torque

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

• Spur gears are the most common type and have straight teeth

• Helical gears have...read more

Coupling is a device used to connect two shafts together at their ends for transmitting power.

• Couplings are used to transmit power from one shaft to another.

• They are used to compensate for misalignment between the shafts.

• Couplings can also be used to absorb shock and vibration.

• Examples of couplings include gear couplings, jaw couplings, and fluid couplings.
