Abstract: The meshing equation of the toroidal drive with cylindrical tooth is established by using space meshing theory, and the calculation formulas of pressure angle of the planet worm gear and the toroidal internal gear are also given,and the major influencing factors are analyzed and forecasted. The project is carried out by adopting the orthogonal experiment table including four row influencing factors and three column influencing factors, the influencing factors and the changing law of the mechanism pressure angle are obtained. The pressure angles of the planet worm gear and the toroidal internal gear are changed by the planet worm gear rotation. The pressure angle of the planet worm gear is sensitive to its radius and the pressure angle of the toroidal internal gear is sensitive to transmission ratio, and they both are least influenced by the radius of roller. The maximum value of the pressure angle is obtained at the middle point of the meshing process. The ideal pressure angle and maximum efficiency of toroidal drive are achieved by adopting reasonable parameters. The presented results provide the theoretical basis for the design and manufacture of toroidal drive.
Key words: Meshing equation, Pressure angle, Toroidal drive
