Mixed type dynamic pressurized gas radial bearing

摘要

A hybrid dynamic pressure gas radial bearing comprises an outer sleeve of the bearing, an inner sleeve and at least one elastic part of the sheet type arranged between the outer sleeve of the bearing and the inner sleeve, the outer circumferential face and the end faces. The left and right of the inner bearing sleeve are respectively provided with regular groove-type patterns, characterized in that the groove-type patterns on one end face are in mirror symmetry with the groove-type pattern on the other end face, and the axial contour lines of the groove-type patterns on the outer circumference face and the radial contour lines of the groove-type patterns on the left and right end faces are in one-to-one correspondence and are connected to each other .
