Research on evolution laws of pitch cones and characteristic values on whole tooth surface of hypoid gears

Abstract

A new method for calculating the parameters of the hypoid pitch cone, which simplifies the calculation process, is proposed. The method can easily obtain the evolution laws of hypoid pitch cones. The evolution limits of the hypoid pitch cone can be obtained by calculation. The pinion pitch cone evolves from cylinder to cone, and the gear pitch cone evolves from plane to cylinder. In the evolution process, all pitch cones can meet the preset values of key parameters. The variation law of the values representing lubrication and contact characteristics on the whole tooth surface during the evolution of pitch cone is studied.
