ABSTRACT:
There is disclosed an infinite circuit using rolling bearings for providing the rectilinear motion. This circuit comprises: rolling elements consisting of rollers or balls; rolling bearings, constituted by the rolling elements, for providing the infinite rectilinear motion by endlessly circulating the rolling elements in an infinite circuit while keeping the direct contact relation with each other; rectilinear track and return passages; two direction reversing passages which connect both ends thereof. The direction reversing passage consists of two quarter-circular passages and an intermediate rectilinear passage provided therebetween. The cross section of each rolling element has the same diameter. In this invention, the traveling amount of each rolling element at each position in the infinite circuit can be made uniform, thereby minimizing the stick slip of the rolling elements while they are rolling in the circuit, so that it is possible to obtain the infinite circuit with less sliding resistance. Also, the moving direction of the rolling elements can be smoothly reversed.
