OPTIMIZATION OF PARAMETERS OF HELICON DRIVES ON THE BASIS OF THE TRIBOLOGY CONDITIONS

Abstract

The relationships being derived by the kinematic method make possible the digital simu- lation of the meshing conditions, the exact determination of the curvature of the meshing tooth surface during the engagement, the analysis of the conditions being necessary to avoid the undercut of the tooth surface on the face-typed gear. and the numerical analysis of the effect of the geometrical parameters. The positions of the line of contact change to a significant extent due to the position of the worm. The angle enclosed by the tangent of the pitch line in the point of contact with the vector of the relative velocity served for the qualitative estimation of the position of the pitch lines. Since the magnitude of the angle enclosed by the contact line and the relative veloc- ity vector is suitable only for an approximate estimation of the helicon drives. Complex kinematic and geometrical indicatrixes including the velocity and curvature, and charac- terising the hydrodynamical conditions served for the detailed analysis of the toothing data and for optimization of the position of the worm.
