The present invention relates to a pre-assembly unit having two tapered roller bearings for a driven shaft, designed to be efficiently replaced and to maintain optimal sealing properties as in factory assembly. The bearing includes a rubber seal attached to a side of the inner race of one of the tapered rollers opposite the smooth face of the other tapered roller. The necessary widening of the inner race requires a second invention, i.e., a roller cage that allows the rollers to slightly rock so as to be assembled without causing damage or becoming damaged.

    本发明涉及一种预组装单元,其具有两个锥形滚柱轴承,该预组装单元用于从动轴,设计成被有效地更换并且像工厂组装那样维持最佳的密封性。所述轴承包括附接到其中一个锥形滚柱的内座圈的侧面上的橡胶密封件,所述侧面与另一个锥形滚柱的光滑面相对。内座圈的必要加宽需要第二发明,即,允许滚柱轻微地摇动以便被组装而不引起损坏或变得损坏的滚柱保持架。
