The invention relates to an eccentric bearing sealing and riveting retaining device and an eccentric bearing sealing and riveting structure, and the eccentric bearing sealing and riveting retaining device comprises a limiting ring which is coaxially arranged outside a small-diameter section of an eccentric bearing in a circling manner and is attached to the inner wall of a steering gear shell; the at least two riveting pieces are connected to the outer wall of the limiting ring, are arranged at intervals in the circumferential direction of the limiting ring and are used for being riveted to the end face of the steering gear shell; the riveting ring is arranged in the limiting ring and is coaxial with the limiting ring, the riveting ring is connected with the limiting ring through a connecting structure, the riveting ring is used for being arranged outside the small-diameter section of the eccentric bearing in a surrounding mode and attached to the outer wall of the eccentric bearing, the riveting ring is provided with at least two riveting points, and the at least two riveting points are arranged in the circumferential direction of the riveting ring at intervals; the riveting ring is suitable for being damaged at the riveting point and riveted to the end face of the eccentric bearing. The eccentric bearing and the steering gear shell are connected through the sealing rivet retaining device, the sealing rivet retaining device and the eccentric bearing are two independent workpieces, quenching treatment is conducted during manufacturing, and the part manufacturing difficulty and cost are reduced.

    本发明涉及一种偏心轴承封铆保持装置及偏心轴承封铆结构,包括:限位环,其用于同轴圈设于偏心轴承小直径段外并贴合转向器壳体内壁;连接于限位环外壁上的至少两个铆接件,至少两个铆接件沿限位环周向间隔设置,铆接件用于与转向器壳体端面铆合;铆接环,其设于限位环内且与限位环同轴,铆接环通过连接结构与限位环连接,铆接环用于圈设于偏心轴承小直径段外并贴合偏心轴承外壁,铆接环上设有至少两个铆接点,至少两个铆接点沿铆接环周向间隔设置,铆接环适于在铆接点处被破坏并与偏心轴承端面铆合。本申请通过封铆保持装置连接偏心轴承与转向器壳体,封铆保持装置和偏心轴承为两个独立的工件,制造时分别进行淬火处理,降低零件制造难度和成本。
