Tapered roller bearing |
| abstract |
A tapered roller bearing comprises an inner ring having a conical surface-like raceway surface in it outer periphery and formed with a cone back face rib and a cone front face rib on the opposite sides of the raceway, an outer ring having a conical surface-like raceway in its inner periphery, a plurality of tapered rollers interposed between the raceways of the inner and outer rings, and a cage for holding the tapered rollers in predetermined circumferential intervals, wherein the ratio R/R BASE of the radius of curvature R of the large end face ( 32 ) of the tapered roller ( 30 ) to the distance R BASE from the apex of cone of the tapered roller ( 30 ) to the cone back face rib surface ( 18 ) of the inner ring ( 10 ) is set at 0.75 to 0.87, and the end face deflection of the large end face ( 32 ) of the tapered roller ( 30 ) is 3 μm or less. |
