Abstract
Abstract Combined radial and thrust rolling bearing having inseparable component parts for a shaft defining an inner raceway for the radial bearing and a raceway for the thrust bearing. The combined bearing comprises; a radial cage for the needles of the radial bearing and a thrust bearing cage for the rolling members of the thrust bearing. A case defines a cylindrical outer raceway for the radial bearing needles and a radial support for the thrust bearing and defines at the end opposed to the radial support a flange for retaining the radial bearing cage. The outside diameter of the thrust bearing cage exceeds the diameter of a geometric cylinder inscribed within and tangent to the needles and this cage retains the thrust bearing rolling members in respect of movement away from the radial support. The needles are retained by the radial bearing cage in respect of movement radially inwardly of the bearing. The cages have adjacent rim portions capable of coming into sliding contact with each other and relatively rotating. Means are provided which define a raceway adjacent the radial support for the thrust bearing rolling members. The radial bearing cage is axially retained by direct contact with either the radial support or with a portion of the thrust bearing cage which is in direct contact with the radial support.
