摘要:
In an embodiment, a bearing apparatus comprises a first bearing assembly including a plurality of circumferentially-spaced first bearing elements each of which includes a first bearing surface. The bearing apparatus further includes a second bearing assembly including a plurality of circumferentially-spaced second bearing elements each of which includes a second bearing surface oriented to engage the first bearing surfaces of the first bearing assembly during operation. At least one of the second bearing elements may be circumferentially spaced from an adjacent one of the second bearing elements by a lateral spacing greater than a lateral dimension of the at least one of the second bearing elements.
摘要(中):
在一个实施例中,轴承装置包括第一轴承组件,其包括多个周向间隔开的第一轴承元件,每个轴承元件包括第一支承表面。 轴承装置还包括第二轴承组件,其包括多个周向间隔开的第二轴承元件,每个第二轴承元件包括在操作期间定向成与第一轴承组件的第一支承表面接合的第二轴承表面。 第二轴承元件中的至少一个可以与第二轴承元件中的相邻的一个圆周间隔开大于第二轴承元件中的至少一个的横向尺寸的横向间隔。
