This paper presents a standardization model for the analysis of rolling bearings in transmission systems. A procedure was applied to assist gearbox prototype development. A solid methodology with robust software, based on international standards, allowed the development engineers to shorten simulation time. In this case, the calculations were performed taking into account system elasticity, which resulted in an exact calculation of the internal load distribution in the bearing, including contact pressure, tilted position and with rolling element profile, considering effects of lubrication conditions and contamination. The program also evaluates the resulting forces of gears, displacement, shaft deflection, contact pressure, stresses, torsion and inclination of the shafts. All the information processed aims at providing safe design, optimal solution and cost impact.

Clutch systems applications require that their components resist to high dynamics and static efforts that should be considered in the development process. These requirements are determined taking account the vehicle application, such as loadcases, materials, life time and environment conditions. In the case of CRB components generally the design is based on contact angular ball bearing. Normally static analysis are performed, computing stresses and displacements, however in this specification the results are checked using static and fatigue safety factors according to the strength assessment evaluation, Germany standard: FKM (Richtlinie - Rechnerischer Festigkeitsnachweis für Maschinenbauteile). Actually more powerful computers have reduced gradativally the cost for industries and with the constant improvements of FE programs, it is possible to simulate the complete assembly using contact interactions to get closer to the reality.
