The Effect of the Ball-Track Connection on the Energy Behavior of the Roller Gearing Gearbox

Abstract

In this paper, I present an energetic study of the roller gearing gearbox by investigating the friction phenomena at the ball-track contact. The novelty of the subject is that the gearbox under investigation is a Hungarian invention, the energetic investigation of which has not been dealt with before. The study was carried out using a mathematical model based on analytical principles, in the course of which the principles and models used for ball bearings and ball screw drives were adapted and applied accordingly. It is important to mention that the study does not cover the complete gearbox, so losses outside the ball-race contact, e.g. bearing friction, seal friction, oil friction, air friction, etc., have not been considered in this paper.
