ASYMMETRICAL TAPERED ROLLER BEARING FOR THE PURPOSE OF MOUNTING A GEARWHEEL ON A GEARSHAFT

摘要

A bearing assembly for a transmission of a vehicle, including: a gearwheel; a gearshaft; and a double-row, asymmetrical tapered roller bearing between the gearwheel and the gearshaft, in an O arrangement and including a first row of tapered rollers, which adjoins a shaft end and a second row of tapered rollers, which adjoins the first row of tapered rollers. The first and second rows of tapered rollers are arranged between a shared outer ring arranged on the gearwheel and separate, dedicated inner rings arranged on the gearshaft. A first acute contact angle on the first row of tapered rollers is not equal to a second acute contact angle on the second row of tapered rollers. The first contact angle is at least 3° less than the second contact angle. A difference between the second contact angle and the first contact angle is at most 10°.
