Oct 31 2018 · Line of action. Due to the special design of the tooth shape of an involute gear (rolling a straight line on a circle) the intersection of two involutes rolling off each other describes a straight line. This situation occurs when two gears are meshing. The involute tooth flanks then slide along a straight line (black line in the animation below).

Chat OnlineWhat are bevel gears The standard definition of a Bevel Gear is a cone-shaped gear which transmits power between 2 intersecting axels. Looking at bevel gears from the differences in helix angles they can be generally classified into straight bevel gears which do not have helix angles and spiral bevel gears (including zerol bevel gears) which do have helix angles.
