Helical gears have the advantages of smooth transmission,large bearing capacity and small axial force,and are widely used in reducers of aviation gas turbines,large crane structures and core drive components of marine power system.This paper summarizes the development of elastohydrodynamic lubrication theory at home and abroad,elaborates the application and calculation method of elastohydrodynamic lubrication theory in gear transmission system,discusses the research status of Point Contact Elastohydrodynamic Lubrication of helical gears,and points out the research focus and development direction in the future.
