Integral shaft-connect type fan clutch bearing

Abstract

The invention discloses an integral shaft-connect type fan clutch bearing. The bearing adopts a row of rollers and double-row steel balls, the double-row steel balls adopt an angular contact structure in a geometric form, the bearing comprises a bearing outer ring, a mandrel, a steel ball holder, a roller holder and a seal ring, wherein channels and a raceway are machined on the bearing outer ring and used for bearing the rolling elements and guiding the rotation of rolling elements, the rolling elements comprise the steel balls and the cylindrical rollers, the mandrel is inserted into the bearing outer ring in the axial direction, inner channels are machined on the outer diameter of the mandrel and used for bearing the steel balls and guiding the rotation of the steel balls, an inner raceway is further machined on the outer diameter of the mandrel and used for bearing the cylindrical rollers, the steel ball holder is arranged between the bearing outer ring and the mandrel and makes the steel balls distributed in the channels at equal intervals, the roller holder adopts a design of a cylinder-shaped structure and a spring collar structure, a spring collar is assembled on the bearing outer ring in a matched mode to prevent the cylindrical rollers from springing out in the axial direction, and the sealing ring is installed in a seal groove formed in the end of the bearing outer ring in a pressed mode and remains still with the bearing outer ring.
