Study of the Kinematic and Dynamic Characteristics of a Wormgear Transmission forHelicopter Applications

摘要

The first phase of the study of the performance of a wormgear transmission isreported. In this phase the work included the selection of a double-enveloping wormgear type, and its dimensions, suitable for use in helicopter transmissions; the 3-D graphics representation of the selected wormgear using the I-DEAS software; the analysis of the kinematics of meshing; the analysis of load sharing among the meshing teeth; and the implementation of the analyses in a computer program. The report describes the analyses, their results, and the use of the computer programs.
