Contact temperature analysis of the classical Geneva mechanism through numerical methods

Abstract

In this study, the flash temperature of the classical Geneva mechanism has been studied using the numer- ical method. An excessive sliding motion between the wheel and pin leads to the generation of heat at the contact surfaces, which raises the surface temperature of the two contacting bodies. The flash tempera- ture has been anticipated for different loading cases and coefficients of friction. The analytical Blok equa- tion results are compared with the finite element results, and the results are satisfactory for maximum temperature. Based on the simulation results, the maximum contact temperature occurred in the driving crankpin within 10-15° and 70–75° of the angular position, and as the load increased the contact temper- ature also increases. In addition, the angular velocity increment produced higher temperatures than the torque load increments.
