Analysis of the HCR gearing from warm scuffing point of view

Abstract

The issue of design and dimensioning of HCR gearing, particularly of the gearings with an internal engagement is nowadays especially in the design of hybrid cars drives highly topical. This kind of gearing has many advantages in operation, but at the same time it is more complicated in the stage of its design and load capacity calculation. Authors present in this contribution some results of warm scuffing research of internal and external HCR gearing. There are given the equations for calculation of warm scuffing resistance of both external and internal HCR gearing derived according to the integral temperature criterion.
