Title:
COMBINED BEARING
Document Type and Number:
WIPO Patent Application WO/2021/129427
Kind Code:
A1
Abstract:
A combined bearing comprising a radial bearing (100) and a thrust bearing (400) that are fixedly connected, wherein the radial bearing (100) comprises a rotating shaft bearing (101) and a stator bearing (102), the rotating shaft bearing (101) is a contact type bearing, the rotating shaft bearing (101) is arranged on a rotating shaft (200) in a sheathed manner, the stator bearing (102) is a non-contact type bearing, the stator bearing (102) is arranged outside the rotating shaft bearing (101) in a sheathed manner, a gap is reserved between the stator bearing (101) and the outer wall of the rotating shaft bearing (102), the stator bearing (101) is fixed on a stator, the thrust bearing (400) comprises a foil (401), an elastic body (402) and a thrust bearing shell (404), the thrust bearing shell (404) covers a thrust disc (300), the thrust disc (300) is fixed to or integrally provided with the rotating shaft (200), the thrust bearing shell (404) is arranged on the rotating shaft (200) in a sheathed manner, the inner side end face of the thrust bearing shell (404) is fixedly provided with a foil sheet (401) by means of the elastic body (402), a gap is reserved between the foil sheet (401) and the thrust disc (300), a thrust bearing air inlet (403) is provided in the thrust bearing shell (404), and the thrust bearing shell (404) is fixed on the stator. The combined bearing not only solves the problem of wear in the radial direction of the support bearing, but can also limit the rotating shaft displacement in the axial direction.
