Abstract:
The paper presents the results of the research of an innovative scheme of a friction Variator with a large load capacity and minimized sliding in the process of adjusting the transmission ratio.
This is achieved by making the friction surfaces at the contact point have close modulus and different curvatures, i.e. one to be convex and the other concave, while they must be contours of centroid pairs. In this way the unwanted slippage is minimized when controlling the Variator.
Based on the differential geometry, the equations of the conjugated contours were obtained in the analytical form of which the friction rotary surfaces were constructed.
The range of change in the transmission ratio of the proposed, significantly exceeds three (D>3) - the most common in engineering practice.
