Geometric Modeling of Spiral Bevel Gear under Virtual Reality

摘要

Based on machining principles of spiral bevel gear and coordinate transformation matrix, the formate-cut wheel model was built. The gear tooth surface of the model has controllable error and can be imported into the Virtual Gear Measuring Center (VGMC) to be virtually measured. The various factors that affect the gear model accuracy were analyzed and the error control strategy was proposed, which lays a solid foundation for the realization of the gear tooth surface measurement and error analysis of spiral bevel gears.
