Tolerance Design of the Journal-Bearing Kinematic Joint. Numerical Analysis of the Effect of the Shape Variations on the Performances
In this work the authors deal with the problem regarding tolerance design of the journal – bearing kinematic joint, in which hydrodynamic lubrication conditions are realised. In particular, they propose a simplified numerical approach to analyse consequences of macro geometric variations on the performances of this kind of bearings. The final result is numerical formulation of new abacuses to be used in the design of such kinematic joints that show how the kinematic joint performances change when the functional feature has not the ideal shape. The designer can use the abacus starting from a performance objective and evaluating the maximum allowable macro geometric error (i.e. the tolerance value) that satisfies the functional requirements.
