Tip
of a tooth of a mating gear digs into the portion between base and root circles
Gears
do not move smoothly in the absence of lubrication
Pitch
of the gear is not same
Gear teeth are undercut
Tip
of a tooth of a mating gear digs into the portion between base and root circles
●Mating
of two non-conjugate (non-involute) teeth is known as interference because the
two teeth do not slide properly and thus rough action and binding occurs.
●Owing
to non-involute profile, the contacting teeth have different velocities can
lock the two gears.
Hence,
the correct option is (A).
