Designing Aspects of Cylindrical Transmission

Abstract

The cylindrical transmission with balls is a new type of mechanical transmission, that allows movement transmission between two coaxial shafts [1]. In the first part of this paper presents the geometric and kinematics study of the elements of cylindrical -sinusoidal transmissions with balls, determining in this way the transmission ratios. In the second part of this paper presents the geometric and kinematics study of the elements of differential cylindrical transmission with balls, determining in this way the transmission ratios. An advantage of this transmission, as compared to other mechanical transmissions, is given by the possibility to obtain more transmission ratios. In case all cylinders of simple cylindrical transmission are moving elements a differential transmission it obtained. Another advantage is given by the possibility of obtaining complex transmissions by series and/or parallel arrangement of cylindrical transmission simple units.

Spherical Planetary Ball Transmissions: Geometrical Synthesis

“…Transmissions with radial [2] and axial [3] movements of rolling bodies in the process of work are well known. Some mechanisms contain many intermediate movable elements and are difficult to make and assemble [4].…”
