Production & Maintenance Engineer Interview Questions and Answers for Freshers

There are three main types of views shown in engineering drawings: front view, top view, and side view.

• Front view: Shows the object as it would appear from the front

• Top view: Shows the object as it would appear from the top

• Side view: Shows the object as it would appear from the side

Spur gears have straight teeth and are used for high speed applications, helical gears have angled teeth for smoother operation, and rack internal gears are used in linear motion systems.

• Spur gears have straight teeth that are parallel to the gear axis

• Helical gears have angled teeth for smoother and quieter operation compared to spur gears

• Rack internal gears are used in linear motion systems where a gear rotates around a fixed rack

There are several types of gears including spur gears, helical gears, bevel gears, worm gears, etc.

• Spur gears: Most common type with straight teeth

• Helical gears: Teeth are cut at an angle for smoother operation

• Bevel gears: Used to transmit motion between intersecting shafts

• Worm gears: Used for high reduction ratios and high torque applications
