摘要

The objective of this paper is to develop a new computational method of friction power loss of the spiral bevel gears transmission system of the helicopter tail reducer. At first, the velocity and force of the meshing point were analyzed during meshing process. Then a computational model of friction power loss for spiral bevel gear was established based on the principle of meshing and tribology theory, considering the effects of actual contact ratio and time-variant factors. This model considered the effects of actual contact ratio and time-variant factors including mesh point relative sliding velocity of mesh point, normal load, friction coefficient, etc.
