The Hertzian pressure (normal stress) in the contact zone between the ball/roller and raceways causes a plastic deformation of the ball/roller contour. In the contact area, the oil-film thickness is nearly constant at the height h
and reduces to the height at h
min at the outflow of the contact zone (cf. Chap. 4). The Hertzian pressure p
in the oil film at the contact zone is calculated in the following section.
- Contact Zone
- Maximum Shear Stress
- Ball Bearing
- Curvature Difference
- Ceramic Ball
