Full Tooth Surface Flash Temperature Distributions and Anti-Scuffing Optimization of Tooth Modification for Face Gear Drives
To rapidly calculate the full tooth surface flash temperature distributions of face gear drives
following Blok flash temperature formula
tooth contact analysis and loaded tooth contact analysis technology
a calculating model for full tooth surface flash temperature distribution of face gear drives is established by evaluating the tangential velocity comprehensive curvature radius of the discrete points on contact ellipse long axes load density and semi-width of the Hertzian contact band. Combining with the fast elitist non-dominated sorting genetic algorithm II
an antiscuffing optimization schedule of tooth modification for face gear drives is constructed by regarding eight parameters of curves on modified pinions as the optimization variables and the minimum tooth surface flash temperature as the optimization objective. The calculations examples show that the flash temperature on the contact ellipse long axes near the pitch cone approaches 0 ℃
the farther the contact ellipse long axis from the pitch cone
and the higher the sliding velocity and flash temperature on the contact ellipse long axis
the scuffing failure is more prone to occur on the mesh-out contact elliptical long axis. Once optimizing the modification parameters of the pinion
the maximum tooth surface flash temperature decreases by 29.9%
thus improving the antiscuffing capacity of face gear drives.
