Establishment of Straight Profile Hourglass Worm under Virtual Reality
Journal of Physics: Conference Series, 2023 Abstract Virtual workpiece is widely used in dynamic simulation and can be imported into the Virtual Gear Measuring Center (VGMC) to be virtually measured. The tooth surface of hourglass worm is complicated, so the dynamic meshing performance is often improved by modification of the tooth surface.
