Abstract
A roller segment is rotatively mounted on a trunnion and rolls along a track. The trunnion may be one of the arms of a tripod element of a homokinetic joint, in which case the track is carried by the other element of the homokinetic joint. In the unloaded state, the inner peripheral wall of the segment has such a shape that its part deformed under load will have an extended area of contact with the trunnion. The material which defines the wall beyond the section of revolution corresponds to the deflection the segment will undergo in service under the effect of cumulated stresses of bending moment and shear under the effect of the load applied at a point by the track and in the distributed form by the trunnion. Utilization thereof for achieving a conformity whose precision allows a hydrodynamic lubrication.
