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.
结果表明:在MEMS微转子系统中,微转子轴衬偏心距离和转子轴衬半径影响线磨损率,以两者减至最小为较理想,但须注意设计中轴承半径的限制,并使轴衬偏心距离大于轴承内半径;在转子加工制造许可的范围内,可以通过调整转子轴衬的半径和偏心距离来减少摩擦磨损对微电机的影响,随着转子所承受载荷和转子旋转速度的增加,其磨损严重;接触区的应力分布不同于经典Hertz解,这是由于应力集中出现在不连续的曲率线上,且接触区的接触压力呈现轴对称抛物线状分布。
