In this article, a mathematical description of tooth flank surface of the globoidal worm and worm wheel generated by the hourglass worm hob with straight tooth axial profile is presented. The kinematic system of globoidal worm gear is shown. The equation of globoid helix and tooth axial profile of worm is derived to determine worm tooth surface. Based on the equation of meshing the contact lines are obtained. The mathematical description of globoidal worm wheel tooth flank is performed on the basis of contact lines and generating the tooth side by the extreme cutting edge of worm hob. The presented mathematical model of tooth flank of TA worm and worm wheel can be used e.

Then the selected contact lines should be brought to the one tooth side of worm wheel, as shown as example in Fig. Buckingham E. It is now 0.
Maruda R? De Donno: Comput. The longitudinal bearing contact on the face-gear tooth surface has been obtained which will increase the contact ratio. The presented mathematical model of tooth flank of TA worm and worm wheel can be used e?
In order to reduce the sensitivity of straight bevel gear drives to misalignment, a new geometry of such gear drives is proposed in longitudinal direction. Point contact instead of line contact of tooth surfaces is achieved by longitudinal crowning of pinion tooth surface. The tooth surface modeling and tooth contact analysis TCA of straight bevel gear drives have been established. Request Permissions. Litvin ,J.

Keywords: Gears, Stiffness, Helical, External, FE Abstract: The gear stiffness has a direct influence on the dynamic response of transmission systems that include a gear box, the stiffness also controls the load distribution among the teeth in mesh. The stiffness of a gear tooth varies non-linearly as the contact line with the meshing gear tooth moves along the surface of the tooth and the resulting meshing stiffness also includes discontinuities.
