摘要：
This paper deals with the prototype of a new pivot bearing having two degrees of freedom. The idea of the pivot bearing is based on a continuous velocity joint (CVJ). The experimental axial stiffness and contact pressure are compared with those determined by theoretical analysis. Then, it is confirmed that the pivot bearing swings smoothly with a range of +/- 25 degrees. Furthermore, the stiffness of the bearing increases as the swinging angle becomes larger. Therefore, this newly developed pivot bearing may be applied to a parallel mechanism, a joint of robot and so on. (c) 2006 Elsevier Inc. All rights reserved.
