The invention specifically relates to a tapered-roller hub bearing, and belongs to the technical field of bearings. A bearing outer ring is nested on the upper surface of a bearing installation table and assembled with tapered rollers, a roller retainer and a bearing inner ring so as to realize low-friction rotating connection, and the bearing inner ring is nested on the inner surface of a bearing rolling ring; a bearing rotating shaft is rotationally embedded into the inner surface of a hub shaft, so that the bearing rotating shaft rotates to drive the bearing inner ring to rotate, a bearing installation and fixing disc and a bolt table are communicated through a bolt hole, a threaded hole is in threaded fit with a fastening bolt, the bearing installation and fixing disc can be conveniently installed and fixed, and installation workers can conveniently install the bearing installation and fixing disc; and the taper of the bearing inner ring is the same as that of the roller retainer, so that the friction force of bearing rotation can be effectively reduced, roller installation holes of the retainer are formed in the inner surface of the roller retainer in an annular array mode, the tapered rollers can be effectively and conveniently fixed, and then the rotation stability of the tapered rollers is kept.

    本发明具体为一种轮毂圆锥滚子轴承,属于轴承技术领域,轴承安装台的上表面嵌套有轴承外圈并与圆锥滚子和滚子保持架,以及轴承内圈进行组装进而低摩擦的转动连接,通过轴承内圈嵌套在轴承滚动环的内表面,以及轮毂轴的内表面转动嵌入有轴承转动轴,可使得轴承转动轴的转动带动轴承内圈的转动,通过螺栓孔将轴承安装固定盘和螺栓台打通,螺纹孔与紧固螺栓螺纹配合可便于对轴承安装固定盘进行安装固定,方便安装工人进行安装,通过轴承内圈的锥度与滚子保持架的锥度相同可有效降低轴承转动的摩擦力,保持架滚子安装孔环形阵列的开设在滚子保持架的内表面可有效的便于圆锥滚子进行固定,进而保持圆锥滚子的转动的稳定性。
