Steady Temperature of a Cylindrical Roller to Ring in Pump under Friction Heating – Analytical and Experimental Study

<div class="section abstract"><div class="htmlview paragraph">Friction heating in solid cylindrical body contact has been an interesting subject for a long time for physicists (i.e. tribologists) and application engineers. In the current environment where the industry product, such as Diesel Rotary Pump (DRP) which operates at higher speed, the temperature rise from the friction contact is of great importance to the manufacturer for thermal safety and its environment effect.</div><div class="htmlview paragraph">In this paper, a steady-state temperature rise under friction heating is studied on a pump roller to cam ring contact within a cyclic segment of a DRP using quasi steady thermal modeling by both the analytical solution developed to the equations from friction heating and thermal conduction and colling, and the finite element analysis (FEA) method constructed with heat flux data from actual hardware test.</div><div class="htmlview paragraph">In addition to the analytical solution and FEA results, an experimental test was conducted to measure and collect the thermal temperature data adjacent to the contact region to correlate the results from analytical solution and FEA simulation, they are found in good agreement.</div></div>
