Abstract
Based on higher order contact meshing theory of conjugate curvature, to establish normal tooth profile model of a new tooth profile double helical synchronous belt transmission. Finite element analysis software is used for new composite double helical synchronous belt out the stress analysis of variable tooth profile parameters. According to the theory of rigid flexible coupling contact, use the ANSYS Workbench finite element analysis software carry out static nonlinear analysis to the three dimensional finite element model of single tooth meshing. Study on influence regulation of the stress and deformation of the spiral angle, side gap. Belt pulley structure for the belt tooth and strength layer, provides a digital simulation analysis and design method for tooth shape, structure design of the model. And further through the finite element analysis software analysis of some advantages of the new tooth profile double helical synchronous belt compared with the straight tooth synchronous belt.
