Right Answer is: B

SOLUTION

Explanation:

Spur Gear: The teeth are cut parallel to the axis of rotation. The spur gears are used to transmit power between two parallel shafts.

In spur gear, the tooth profile starts from the base circle, covers the face and flank region and finally ends at top of the tooth.

Forms of teeth:

  • Two curves of any shape that fulfil the law of gearing can be used as the profiles of teeth.
  • An arbitrary shape of one of the mating teeth can be taken and applying the law of gearing the shape of the other can be determined. Such gear is said to have conjugate teeth.

Teeth that satisfy the law of gearing are:

  1. Cycloidal profile teeth.
  2. Involute profile teeth.
