The geometric structure of mating surfaces has a crucial influence on the friction and resulting wear processes. This is particularly important in the case of injection pumps, where ensuring appropriate surface quality and tightness in a long-term operation process is extremely important in order to maintain nominal operating parameters. It is extremely important during variable pump operation conditions,...
Badania zespołów napędowych potwierdzają, że do najszybciej zużywających się w wyniku wieloletniej eksploatacji podzespołów w silnikach wysokoprężnych maszyn i pojazdów należą pompy wtryskowe rzędowe i rozdzielaczowe. Trwałość pomp jest kilkakrotnie mniejsza od trwałości silników. W silnikach wysokoprężnych pojazdów stosowano kilkanaście różnych wielkości i rodzajów pomp wtryskowych rzędowych, co...
The paper presents the methodology for designing the injection shaft drive for diesel engines with 2,3,4,6 and 8 cylinders as well as power from 2.5 to 52 kW per cylinder using the FEM method and experimental research. The pump is the original solution of the authors. The shaft is a basic part of the pump with a complex structure. In order to assess the state of stress in the shaft, the FEM analytical...
