The pressure generation within the lubricant fluid present in the clearance between a thrust bearing and the collar attached to the shaft has a fundamental importance to avoid contact between solid parts with axial relative motion. Any existing contact can lead to friction, wear and, as a consequence, failure of elements on a rotating machine. Therefore, in order to design an effective bearing, it is important to know how the pressure is generated within the oil film and the magnitude of the load capacity transmitted from the collar to the bearing throughout the fluid. Thus, it is necessary to solve the Reynolds' Equation to obtain the distribution of pressure on the sections under Hydrodynamic Lubrication. Then several operational parameters can be obtained, such as, the total load capacity, lubricant fluid flow, position of the maximum pressure and so on.

The aim of this work is to adapt a product development process model for BorgWarner Brazil (Turbo Systems division). Campinas plant has not had an integrated model, meanwhile they have been working with different models from USA and Europe plants. Those models, created with different backgrounds, provide some negative points and reworks at Campinas process. The intention is to solve this problem by studying the process development theories, tools from the bibliographic references, and the models used by other plants of the corporation. The created model describes the activities that are current done for new products development, attempting successfully the customers. This project attended to the minimum requirements valid for the whole corporation, improved the current process, validated the company activities and met the requirements of the automobile market. As final result it was proposed cost reduction projects and the optimization of the current process.
