Bearing pressure is a particular case of contact mechanics often occurring in cases where a convex surface (male cylinder or sphere) contacts a concave surface (female cylinder or sphere: bore or hemispherical cup).

This page provides the chapter on the bearing stress (also referred to as contact stress) from the Air Force Stress Manual.

PV is determined by multiplying the specific bearing load or pressure(p) by the sliding speed (v). Bearing materials are rated by a PV limit, with the PV limit representing the highest combination of load and speed under which the bearing material will operate.

experimental study of the stress and lubricant distribution plain pin and bushing pairs. A finite-element study is conducted to determine the contact stress distribution at the interface of the pin and bushing, and comparisons are made to the Hertz contact theory.

Ball bearings, which are designed mainly for rotational motion, are designed with a very small contact area, causing extremely high contact stress. They are unsuitable for oscillation when compared to the large contact area of a bushing.

This research aims to investigate the impact that a bush-bearing surface has on a bearing's ability to operate well when subjected to dynamic load by using CATIA 5.1, ANSYS 2021R1, and MINITAB 19.

Nov 2, 2024 · Bearing stress is the term used to describe the pressure exerted by one object on another at their point of contact. It is essential as it can occur in most pin connections, bolted joints, or surfaces under load.

Static structural analysis of small end bush of connecting rod is done by considering three different materials and they found the Vonmises stress for three materials. S. Dharani Kumar et al (2017) discussed with structural analysis of Connecting rod and crank shaft bearings using ANSYS APDL 15.0.

Summary The big end bearing of a connecting rod is one of the most highly loaded bearings in marine engines. This paper presents a feasibility study and optimization of the geometrical parameters of a bush-cut bronze bearing for connecting rods in large-bore marine engines.
