Modeling and Dynamic Simulation of TI Worm Drivebased on GearTrax

Rail transport conveyer is a kind of special transportation equipment commonly used in the metallurgical industry. One of the crucial reasons leading to the inefficient/poor reliability and low kinetic accuracy of rail transport conveyer is closely related to the transmission system. A precise three-dimension solid model of the TI worm and worm gear is established, which serves as the main transmission structure is built with GearTrax and Solid Edge. ADAMS simulation analytic software is utilized to conduct kinematic simulation analysisthrough inputting modeling of worm transmission structure in rail transport lifting system with Hertz contact theory, and the change rules of driven link bevel tooth rotation speed and worm and gear engaging force are obtained and analyzed. Therefore, it has improved the reliability and efficiency of rail transport conveyer transmission system, and a reference method is provided for 3D solid modeling of TI worm transmission and the dynamics modeling and analysis of worm and gear transmission mechanism.
