摘要
The invention relates to a tapered roller bearing (1) and to a method for assembling the same. The tapered roller bearing (1) substantially consists of an outer bearing ring (2) and an inner bearing ring (3) and a plurality of tapered rollers (4) arranged between said bearing rings (2, 3). The tapered rollers have two respective lateral faces (5, 6) that are symmetrically flattened from a basic spherical shape and that are maintained at a constant distance to each other in the peripheral direction by a window-type cage (7). Each cage pocket (8) of said window-type cage has the entire contour of each cross-sectional contour (9, 10) of a tapered roller (4), said cross-sectional contour arranged alongside and at a right angle to the peripheral direction. The tapered rollers (4) have a width (b?) of approximately 70% of the diameter (d?) of their basic spherical shape and roll off with their raceways (11) in two groove-type raceways (12, 13) machined into the outer bearing ring (2) and into the inner bearing ring (3), said groove-type raceways being axially delimited by respective two lips (14, 15, 16, 17). The radial height of said lips is chosen such that the radial distance (SR, SL) between the lips (14, 15) on the outer bearing ring (2) and the lips (16, 17) on the inner bearing ring (3) is smaller than the width (bK) of the tapered rollers (4). The invention is characterized in that the height of the lip (14 or 15) on the outer bearing ring (2), which lip is designed to absorb the lower axial forces, is radially reduced to such an extent that its inner diameter (DI) is larger than the outer diameter (DA) of a pre-assembled unit consisting of the inner bearing ring (3), the window-type cage (7) and the tapered rollers (4).
