This method is for finish machining the teeth of rough machined bevel gears having longitudinally curved teeth where finish machining is undertaken subsequent to case hardening. To permit economical fabrication of such bevel gears at least in mass production, the bevel gears are ground as workpieces by a tool designed as a hypoid gear and provided with at …

HVPOIDGEARS If the axes between the gears are nonparallel and also nonintersect-ing, bevel gears cannot be used. Hypoid gears will accommodate this geometry. Hy-poid gears are based on rolling hyperboloids of revolution as shown in Figure 9-23. (The term hypoid is a contraction of hyperboloid.) The tooth form is not an involute. These

Spiral bevel gears (Figure 57.16) have curved oblique teeth that contact each other gradually and smoothly from one end of the tooth to the other, meshing with a rolling contact similar to helical gears.Spiral bevel gears are smoother and quieter in operation than straight bevel gears, primarily due to a design that incorporates two or more contacting teeth.
