Prediction of surface roughness of spiral bevel gears

The roughness model analyzes the tooth surface areas of five spiral bevel gears, predicts the surface roughness, and generates the surface morphology and roughness profile of these five areas. Therefore, different roughness along the tool feed direction XW can be predicted. Different tool side number (N) t and feed...

Prediction model of spiral bevel gear tooth surface topography

The developed model estimates that the tooth profile of spiral bevel gears depends on machining parameters, such as tool inclination and direction, cutting geometry parameters and tool feed and speed values. Two different finishing operations tests were carried out on the model, namely, a 5-axis machining operation and a...

Equation of lubricant film thickness for spiral bevel gears

First, confirm the parameters of lubricating oil. The parameters of lubricating oil commonly used on spiral bevel gears are as follows. Ambient viscosity of lubricating oil (kg/m · s) Ambient density of lubricating oil (kg/m3) Viscosity pressure coefficient of lubricating oil (1/Pa) Characteristic shear force of lubricating oil (Pa)...

Positive stress of spiral bevel gear

During the meshing and contact process of spiral bevel gears, the normal stress along the running direction is classified as the main contact surface, and vice versa, based on the running direction of spiral bevel gears. The normal stress value of the main contact surface represents the energy of...
