Patent ID: 8721232

Claim:
A rolling bearing, comprising: a first ring comprising a first rolling surface having an undulating profile; a second ring comprising a second rolling surface, the first and second rings being coaxial to a rotation axis and rotatable one relative to the other; a first row of rolling bodies mounted in rolling contact between the first rolling surface and the second rolling surface, the first rolling surface being configured to impart in a steady-state operating mode a reciprocating axial movement to the first ring relative to the second ring; a first cage in which the rolling bodies are inserted, the first cage holding the rolling bodies with a predetermined angular difference; a third ring coaxial to the axis of rotation and comprising a third rolling surface having an undulating profile, the third rolling surface cooperating with either the first row of rolling bodies or a second row of rolling bodies held together by a second cage, the second row of rolling bodies being inserted between the third rolling surface and a fourth rolling surface of a fourth ring, wherein the first and third rings or the second and fourth rings are mounted to rotate as one in the steady state operating mode and are movable axially one relative to the other so that a relative reciprocating axial movement is imparted to them by the cooperation of the rolling bodies with the first rolling surface and the third rolling surface, and wherein the relative angular position of the first rolling surface and the third rolling surface determines an amplitude of axial reciprocating movements of the rings which rotate as one.
