Results indicate that radial distance of the bushing from the rotor center and the radius of the hemispherical bushing significantly affect wear rate,and minimzing both two values will result in lowest wear for micro-rotor systems in MEMS.However,it is noted that the bearing radius sets a lower limit on the hemispherical bushing radius since the bushings are located beyond the rotor inner radius.It is desirable to reduce their effects on friction and wear on micro-rotors by regulating the radius of the bushing and the radial distance of the bushing from the rotor center within permissive range of micro-fabrication.Severe wear exists with increasing applied load and rotating speed of the rotor.Stress distributions in the contact region are different from Hertz solutions due to the convergence stresses apearing on the uncontinuous curvature line and the contact pressures display symmetrical parabola in the contact region.
