Tutorial of Hertzian Contact Stress Analys

resultant stresses are not of design significance, but in some cases failure can occur. Ball bearings or kinematic mounts that are repeatedly removed and remounted can start to show damage from fatigue caused by the Hertzian stresses. The Hertzian contact stress equations come in two forms, spherical and cylindrical.

Loa

When a radial load is applied to a single row angular contact ball bearing, the load is transmitted from one raceway to the other at an angle to the bearing axis and an internal axial load is induced. This must be considered when calculating the equivalent bearing ...

Contact mechanics - Wikiped

Contact mechanics is the study of the deformation of solids that touch each other at one or more points. A central distinction in contact mechanics is between stresses acting perpendicular to the contacting bodies' surfaces (known as the normal direction) and frictional ...

Angular contact ball bearings - skf.c

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis ().

Ball Bearing Mechanics - NA

fatigue life of ball bearings is developed in Section 3.5. Ball bearings can be lubricated satisfactorily with a small amount of lubricant supplied to the right area within the bearing. Section 3.6 considers the selection of a satisfactory lubricant, as well as describing systems that provide a constant flow of lubricant to the contact.

Chapter 28: Rolling Element Bearings - UF

28.2.1.2 Angular-Contact Ball Bearings Angular-contact ball bearings can be regarded as a variation of deep-groove ball bearings. Unlike deep-groove bearings, an angular-contact bearing has at least one race ring that has only one side shoulder. Angular-contact ball bearings are capable of carrying an appreciable thrust load in one direction with
