Geometric Modeling of Spiral Bevel Gear under Virtual Reality

Abstract

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.

Establishment of Straight Profile Hourglass Worm under Virtual Reality

“…The parameterized virtual workpiece model is fast to modify and reconstruct, which plays a very important role in shortening product design cycle, improving production efficiency and realizing product innovation. At present, Feng Hao has established the virtual workpiece of spur gear and completed the optimization of the face [1]; Wang Jianhua established the virtual workpiece of spiral bevel gear with controllable error and analyzed the factors affecting the accuracy of gear model [2]; Lu Chunxia optimized the virtual workpiece collision algorithm and improved the efficiency of the virtual workpiece model pre-processing algorithm IOP Publishing doi:10.1088/1742-6596/2501/1/012028 2 [3]. I established the virtual workpiece of the straight profile hourglass worm to provide the virtual workpiece model with controllable accuracy for the virtual measurement and TCA analysis of enveloping worm.…”
