Hertzian Contact Stress — Engineering Notes

Witryna28 sty 2024 · For the maximum shear stress, often an approximation is used: 0.32*S hertz (S hertz = Hertzian contact stress). This maximum shear stress occurs below the surface at a depth of approximately 0.48*b (b = minor contact radius). However, this depth only applies to a circular contact. Witryna5 sie 2024 · These stresses are known as Hertz (or Hertizian) contact stresses. In rolling element linear bearings, Hertz contact stresses occur on the balls (or cylinders) and the raceways. In theory, the contact between two spheres occurs at a point, and the contact between two cylinders occurs as a line. In either case — point or line contact — the ...
