    摘要： A pin which acts as a spring directly extends through an outer race without use of an outer-race casing and a pin holder and the central portion of the pin supports the outer race. Axial movement of the pin beyond a predetermined range is restricted by snap rings fitted on the both ends of the pin. An oil film is formed between the outer peripheral surface of the outer race and the inner peripheral surface of casings and oil reservoirs are also defined to damp axial movement of the outer race. That is, the pin which acts as a spring directly extends through the outer race of the bearing in parallel with a rotating shaft and the central portion of the pin elastically supports the outer race. The ends of the pin are supported by the casings through the snap rings. A space in which an oil film functioning as an oil film damper is formed is defined by the outer peripheral surface of the outer race and the inner peripheral surface of the casings. Furthermore, the oil reservoirs which act to damp the axial movement of the outer race are defined by the end faces of the outer race and the casings.

    摘要翻译： 用作弹簧的销直接延伸穿过外圈而不使用外圈外壳和销保持器，并且销的中心部分支撑外圈。 销超过预定范围的轴向运动受到安装在销的两端的卡环限制。 在外圈的外周面和壳体的内周面之间形成油膜，并且油槽也被限定为阻止外圈的轴向移动。 也就是说，作为弹簧的销直接通过轴承的外圈平行于旋转轴延伸，并且销的中心部分弹性地支撑外圈。 销的端部通过卡环支撑在壳体上。 形成作为油膜阻尼器的油膜的空间由外圈的外周面和箱体的内周面形成。 此外，用于抑制外圈的轴向运动的储油器由外圈和外壳的端面限定。
