Generation and Meshing Analysis of a New Type of Double Helical Gear Transmission

Abstract EN

A study on the double helical gear transmission with curve element constructed tooth pairs is carried out in this paper.

Generation and mathematical model of tooth profiles are proposed based on the geometric relationship.

Tooth profiles equations are derived considering the developed equidistance-enveloping approach.

Design of tooth profiles with point contact is conducted and numerical example is illustrated.

And the solid models of double helical gear pair with curve element constructed tooth pairs are established.

Computerized design and meshing simulation are also put forward.

Furthermore, stress analysis of the gear pair is conducted and gear prototypes are manufactured using CNC machining technology.

Further tooth contact analysis, dynamic and experimental studies on transmission properties of gear prototypes will be carried out.
