Abstract
<p>Ball joints are automotive products that perform reciprocating sliding motion of metal and resin components with grease lubrication between them. Understanding the effects of temperature on the characteristics of product components and their elements is necessary to design ball joints that are applicable to a wide range of temperatures. The viscosity of the grease base oil has the most effects of temperature. To investigate the applicability of PDMS base oil grease, which has a smaller viscosity dependence than the current PAO base oil grease, the lubrication properties of PDMS oil and PAO oil between resin (POM) and metal (chromium molybdenum steel) were studied by reciprocating sliding friction test. Seven PDMS oils with a wide range of viscosities were used in the experiments, assuming that the viscosity of the oil changes over the temperature range required for practical use. Lower viscosity PDMS showed an increase of contact areas in mixed lubrication mode but effect on the friction coefficient was small while higher viscosity PDMS caused lubrication starvation in the latter half of the test. These results indicate that there is an upper limit of viscosity where lubrication can be maintained.</p>
