Abstract: The contact hydrodynamic theory of lubrication takes into account hydrodynamic and heat processes in the lubrication film and the elastic deformations of the solid surfaces being in contact. In the gear-drives the load is carried by the conjugate tooth surfaces and by the lubrication film between them. Òwo mutual connected problems – a hydrodynamic lubrication problem and a contact problem of elasticity are presented. The paper does not give a mutual solution of the above problems. The purpose is to suggest a quality estimate of the influence of some characteristics on the gear pair loading capacity. A kinematic approach to defining characteristics for estimating the hydrodynamic loading capacity of the Wildhaber type gearing is presented.
