    • A rotating machining device (100) includes a segmented support housing (102) arranged to be mounted on a work piece and a segmented headstock (104) mounted on the support housing (102) and rotatable relative to the support housing (102) about an axis (128). At least one bearing assembly (158) is disposed between the headstock (104) and the support housing (102). The at least one bearing assembly (158) includes a first race (162) having a first set of bearing elements (166) arranged to dynamically contact a first portion (133) of the headstock (104) and reciprocate within the bearing assembly (158) in a first direction. The at least one bearing assembly (158) also includes a second race (164) having a second set of bearing elements (168) arranged to dynamically contact a second portion (125) of the headstock (104) and recirculate within the bearing assembly (158) in a second direction opposite the first direction so as to promote distribution of a load applied to the bearing assembly (158).
    • 旋转加工装置(100)包括布置成安装在工件上的分段支撑壳体(102)和安装在支撑壳体(102)上并且相对于支撑壳体(102)可旋转的分段主轴箱(104) 轴(128)。 至少一个轴承组件(158)设置在主轴箱(104)和支撑壳体(102)之间。 至少一个轴承组件(158)包括具有第一组支承元件(166)的第一座圈(162),所述第一组轴承元件布置成动态地接触所述主轴箱(104)的第一部分(133)并在所述轴承组件(158)内往复运动 )在第一方向。 所述至少一个轴承组件(158)还包括具有第二组轴承元件(168)的第二座圈(164),所述第二组轴承元件布置成动态地接触所述主轴箱(104)的第二部分(125)并且在所述轴承组件 158)在与第一方向相反的第二方向上以促进施加到轴承组件(158)的负载的分配。
