Helix angle: It is a constant angle made by the helices with the axis of rotation. 2. Axial pitch: It is the distance, parallel to the axis, between similar faces of adjacent teeth. It is the same as circular pitch and is therefore denoted by p c. 3 ... incdif ispifWebA parallel helical gearset uses a 20-tooth pinion driving a 36-tooth gear. The pinion has a right-hand helix angle of 30°, a normal pressure angle of 25, and a normal diametral pitch of 4 teeth/in.

Gears will only mesh with each other if they have teeth of the same module. Pitch (p) represents the distance between teeth, and since a larger pitch means a larger tooth size and a smaller pitch means a smaller tooth size, the pitch can be used to represent the tooth size. incdtxtWebTwo meshing helical gears have parallel shafts.
