径向滚珠轴承以及方法
摘要：
一种用于心轴的轴承部分，该心轴至少部分地设置在壳体的内部孔内。径向轴承和推力轴承各自围绕心轴设置且设置在壳体的内部孔内。径向轴承包括外部圆柱形构件、内部圆柱形构件和设置在外部圆柱形构件的内部表面和内部圆柱形构件的外部表面之间的空间内的一系列球形构件。外部圆柱形构件的内部表面或内部圆柱形构件的外部表面中的一个包括平坦轮廓，并且另一个包括一系列圆周凹槽。平坦轮廓允许内部圆柱形构件和外部圆柱形构件之间的相对轴向移动，而径向轴承不吸收任何推力载荷。
摘要（英）：

A bearing section for a mandrel at least partially disposed within an inner bore of a housing. A radial bearing and a thrust bearing are each disposed around the mandrel and within the inner bore of the housing. The radial bearing includes an outer cylindrical member, an inner cylindrical member, and a series of spherical members disposed within a space between an inner surface of the outer cylindrical member and an outer surface of the inner cylindrical member. One of the inner surface of the outer cylindrical member or the outer surface of the inner cylindrical member includes a flat profileand the other includes a series of circumferential grooves. The flat profile allows relative axial movement between the inner and outer cylindrical members without the radial bearing absorbing any thrust load.
