| Outline of Final Research Achievements |
A novel lightweight and low starting torque bearing was proposed with looped carbon fibers brush (LCFB). LCFB showed that the static friction coefficient was nearly equal to the kinetic friction coefficient. By applying LCFB as a slide bearing, a ratio of starting torque to regular torque of LCFB slide bearing is 0.93～1.07 which is smaller than that of the slide bearing which showed 1.19～1.33. When micro-spline shaft is used as a mating material of LCFB slide bearing, the torque reduces because of decrease of real contact area between LCFB and mating materials. We also define the load capacity of LCFB slide bearing by using buckling load of a carbon fiber bundle to avoid overload state.
