    • A rotating machining device includes a segmented support housing arranged to be mounted on a work piece and a segmented headstock mounted on the support housing and rotatable relative to the support housing about an axis. The rotating machining device also includes at least one bearing assembly disposed between the headstock and the support housing. The at least one bearing assembly includes a first race having a first set of bearing elements arranged to dynamically contact a first portion of the headstock and reciprocate within the bearing assembly in a first direction. The at least one bearing assembly also includes a second race having a second set of bearing elements arranged to dynamically contact a second portion of the headstock and recirculate within the bearing assembly in a second direction opposite the first direction so as to promote distribution of a load applied to the bearing assembly.
    • 旋转加工装置包括被布置成安装在工件上的分段支撑壳体和安装在支撑壳体上并且相对于支撑壳体围绕轴线可旋转的分段主轴箱。 旋转加工装置还包括设置在主轴箱和支撑壳体之间的至少一个轴承组件。 所述至少一个轴承组件包括具有第一组轴承元件的第一座圈,所述第一组轴承元件布置成动态地接触所述主轴箱的第一部分并且在所述轴承组件内沿第一方向往复运动。 所述至少一个轴承组件还包括具有第二组轴承元件的第二座圈,所述第二组轴承元件布置成动态地接触所述主轴箱的第二部分并且在与所述第一方向相反的第二方向上在所述轴承组件内再循环,以促进负载的分配 应用于轴承组件。
