Disclosed is a bearing unit (6) having at least one first ring (8) and at least one second ring, which are rotatable relative to each other and define a bearing interior (12) therebetween, the at least one first ring (8) being designed to be attached to a component part (2) by means of a press-fit, the at least one second ring (8) being designed to be connected to the component part (2) by means of a press-fit, and the at least one second ring (8) being designed to be connected to the component part (2) by means of a press-fit. The component part (2) is formed from a first material having a first coefficient of thermal expansion, the at least one first ring (8) is formed from a second material having a second coefficient of thermal expansion, the second coefficient of thermal expansion differing from the first coefficient of thermal expansion, the at least one first ring (8) is provided with at least one insert element (14-1, 14-2, 14-3) on the side facing the bearing interior (12), the at least one insert element (14-1, 14-2, 14-3) is formed from a third material having a third coefficient of thermal expansion, which is substantially at least as high as the first coefficient of thermal expansion.

    公开了一种具有至少一个第一圈(8)和至少一个第二圈的轴承单元(6),至少一个第一圈(8)和至少一个第二圈能够相对于彼此旋转并且在它们之间限定轴承内部(12),至少一个第一圈(8)被设计为利用压配附接到组成部件(2),组成部件(2)由具有第一热膨胀系数的第一材料形成,至少一个第一圈(8)由具有第二热膨胀系数的第二材料形成,第二热膨胀系数不同于第一热膨胀系数,至少一个第一圈(8)在面向轴承内部(12)的一侧设置有至少一个插入元件(14‑1、14‑2、14‑3),至少一个插入元件(14‑1、14‑2、14‑3)由具有第三热膨胀系数的第三材料形成,第三热膨胀系数基本上至少与第一热膨胀系数一样高。
