ABSTRACT

Manufacturing methods of gears for intersected-axes, as well as for crossed-axes approximate real gearings, are based on a design of the gear-cutting tool for machining gear teeth. Gear and mating pinion tooth flanks, Gr.app and Pr.app, are generated as enveloping surfaces to consecutive positions of the generating surface, T, of the gear-cutting tool in its motion in relation to a reference system, which a machined gear is associated with. Two main reasons can be noted for designing, production, and application of approximate real intersected-axes gears in the current industry. First, the tooth flank geometry of perfect real intersected-axes gearing, Gr, is not considered when determining the geometry of the generating surface, T, of the gear-cutting tool for machining gears for approximate real intersected-axes gearings. Second, for the purpose of transmitting a uniform rotation from a driving shaft to a driven shaft, intersected-axes gears that have various generic shapes are used.
