Abstract: In this paper, the theory of gearing and the concept of differential geometry have been applied to deal with the relations of two mating gears and of their bearing contact. The gear tooth ...

Abstract: A dual-lead worm gear set is frequently used for machines to operate without backlash, which can be adjusted along the worm’s axial direction. The ZK-type dual-lead worm is generated by a ...

Abstract: Contact ratio is an important gear design parameter for gear bending and contact stresses. A higher contact ratio may reduce the stresses and kinematic errors of the gear set. In this study, ...

Abstract: This paper proposes and analyzes a new meshing condition between a modified hyperboloidal roller follower and a spatial cam surface. This new geometrical model can be utilized to avoid the ...
