Abstract

Предложена опорная секция для оправки, расположенной, по меньшей мере частично, во внутреннем отверстии корпуса. Каждая из радиальной опоры и осевой опоры расположена вокруг оправки и во внутреннем отверстии корпуса. Радиальная опора содержит наружный цилиндрический элемент, внутренний цилиндрический элемент и множество сферических элементов, расположенных в пространстве между внутренней поверхностью наружного цилиндрического элемента и наружной поверхностью внутреннего цилиндрического элемента. Одна из внутренней поверхности наружного цилиндрического элемента или наружной поверхности внутреннего цилиндрического элемента имеет ровный профиль, и другая содержит множество круговых канавок. Ровный профиль обеспечивает возможность осевого перемещения внутреннего и наружного цилиндрических элементов друг относительно друга без поглощения какой-либо осевой нагрузки радиальной опорой.
