Combined double-row tapered roller bearing with rear stopper

The invention relates to a combined type double-row tapered roller bearing with a rear stopper. The combined type double-row tapered roller bearing comprises a bearing outer ring, a bearing inner ring and two rows of tapered rollers, wherein the two rows of tapered rollers are respectively mounted between the bearing outer ring and the bearing inner ring in a rolling manner through retainers; the rear check ring is mounted at a shaft shoulder of the axle and is propped against the positioning end surface of the bearing inner ring; and the bearing inner ring is fixedly connected with the rear check ring through a clamping ring. The bearing inner ring and the rear retainer ring are fixed together through the retainer ring, so that the positioning end face at the end face of the bearing inner ring is prevented from generating peristaltic wear relative to the end face of the rear retainer ring, and the service life of the double-row tapered roller bearing can be prolonged. 本发明涉及的带后挡组成式的双列圆锥滚子轴承，包括轴承外圈、轴承内圈以及分别通过保
