Analysis of the relationship between improving the performance of worm gear sliding bearings and the use of fi lm-forming lubricants

The paper describes ways to increase the bearing capacity of sliding bearings. The possibility of replacing a rolling bearing with a sliding bearing on a high-speed worm gear shaft is shown. A description of the dynamics of self-oscillations occurring in the worm gear is given, followed by an assessment of the effect of fi lm-forming lubricants on the adaptive properties of sliding pairings. The resource of sliding pairings is calculated taking into account the growth of the dinamic coefficient.
