The tapered roller bearings serviceability is significantly affected by contact conditions between the roller ends and the ring flange. In this regard, the actual task is to determine influence of the contacting surfaces geometric shape on the value of the limiting contact force, where the contact spot boundary reaches the boundary of the contacting end surfaces area projecting on each other, and formation of the oil film between them becomes impossible. The stress-strain state was simulated by the finite element method in the CAE ANSYS software package making it possible to adequately evaluate the complex geometry and describe in detail all the features of this contact. The contact pressure fields obtained as a result of the finite element calculations allowed determining the limiting contact force values depending on the value of the contacting ends reduced curvature.
