What
type of contact occurs during meshing of helical gears?
Point
Line
Area
Volume
Point
●In
helical gears, the teeth are cut in the form of a helix on the pitch cylinder,
the contact between meshing teeth begins with a point on the leading edge of
the tooth and gradually extends along the diagonal line across the tooth,
results in smooth engagement.
●In spur gears the teeth are cut parallel to the axis of shaft. Hence, the contact, between meshing teeth occurs along the entire face width, is line contact.
Hence,
the correct option is (A).
