Abstract

One of the essential requirements of a modern car is that the interior noise level should be low. Preloading of a bearing is an essential method to make sure that the bearing runs perfectly well under its dynamic working conditions. Preloading value of a bearing is decided upon forces applied to it in its working condition. When the preload is applied correctly, it reduces all possible causes of bearing failure and ensures low noise high stiffness at high temperature and speed. This paper investigates methodology to calculate the correct preload level for a combination of duel material housing fuel pump application. As the working conditions and load carrying capacities of fuel pump are extreme, and one bearing was mounted in cast iron housing and other in aluminum housing, due to the difference in coefficient of expansion it is difficult to adjust bearing preload at high operating temperature, and it’s becoming a major cause of onsite failures and it leads to repairs, rework and wastage of man-hours and cost. In order to overcome these failures, the accurate bearing preloading ensures required preload on each bearing, which reduces the onsite bearing failures.
