Contact characteristics of helical conical gears used for V-drive marine transmissions

This article investigates the load-carrying ability of helical conical gears used in transmissions with intersecting and crossed axis for V-drive marine transmission. Mathematical models of helical conical non-involute gears, which can realize line contact, were established on the basis of the conjugated theory. Loaded tooth contact analysis was performed to examine the meshing and bearing contact of the helical conical gear pairs. The contact area was measured in an experiment and compared with theoretical results, and good agreement was observed.
