Slide Bearings for High Pressure Pump

By Marek Novotný


The goal of this diploma thesis is to design the journal bearings for high pressure diesel pump which is part of Common rail system from Motorpal Company. This producer is also submitter of this diploma thesis and as a result it is expecting the reduction of cost price and possible transfer to the diesel oil lubrication. Firstly, there is sum up of issues of high pressure pump by Motorpal. The next part of the thesis describes the journal bearings and its construction, tribology of the journal bearings and also the overview of the materials. These materials are currently being used for securing long time usage and do not require service maintenance during lifespan period. In the practical part there is applied the Multy Body System (MBS) approach with rigid bodies and after that there are used analytic relations, which however do not include impact of movement of the journal center during dynamic stress. The thesis concludes with a comparison of results of both calculations and determination of bearing parameters, which according to the calculations ensure an achievement of hydrodynamic lubrication
