Example Embodiment

[0049] Example one

[0050] The rotating shaft bearing 1 is a ball bearing, and the stator bearing 2 is an air bearing.

[0051] See figure 1 In this embodiment, the parallel bearing includes a rotating shaft bearing 1 and a stator bearing 2. The rotating shaft bearing 1 is sleeved on the rotating shaft 100, and the stator bearing 2 is sleeved outside the rotating shaft bearing 1 and maintains a certain gap with the outer wall of the rotating shaft bearing 1.

[0052] The air bearing is in the shape of an annular cylinder, the outer wall of which is parallel to the end surface is provided with at least one annular groove, a damper is nested in the annular groove, the damper is an annular rubber ring 21, and the top of the rubber ring 21 protrudes Air bearing outer wall.

[0053] See Image 6 , 7 8, 9, the annular end surface of the air bearing is circumferentially and uniformly provided with a plurality of protrusions 22, one end of the air bearing provided with the protrusions 22 is...

Example Embodiment

[0055] Example two

[0056] See figure 2 , The parallel bearing further includes at least one intermediate bearing 6, the intermediate bearing 6 is a contact bearing, the intermediate bearing 6 is sleeved between the rotating shaft bearing 1 and the stator bearing 2, the stator bearing 2 and the intermediate bearing 6 There is a gap between them.

[0057] The intermediate bearing 6 is a ball bearing.

[0058] Specifically, the parallel bearing includes a rotating shaft bearing 1, a stator bearing 2 and an intermediate bearing 6.

[0059] In this embodiment, on the basis of the first embodiment, an intermediate bearing 6 is sleeved on the shaft bearing 1 (or a plurality of intermediate bearings 6 are sleeved in sequence and each intermediate bearing 6 is coaxial), and the stator bearing 2 is sleeved on the outermost The middle bearing 6 is outside and a certain gap is maintained with the outer wall of the outermost middle bearing 6.

Example Embodiment

[0060] Example three

[0061] Further, the ball bearing, roller bearing, ceramic bearing or tetrafluoroethylene bearing is single-layer, double-layer or multi-layer. The ball bearing or roller bearing of the rotating shaft bearing 1 in the first and second embodiments of the present invention can be an integrated multi-layer bearing, and the ball or roller layer is arranged in multiple layers, see image 3 . A multi-layer ball bearing or roller bearing includes an inner ring, an intermediate ring and an outer ring nested in each other, and balls or rollers are respectively embedded between the inner ring and the intermediate ring, and between the intermediate ring and the outer ring.

Abstract

The invention discloses a combined bearing which comprises a radial parallel bearing and a thrust bearing. The parallel bearing comprises a rotating shaft bearing and a stator bearing. The rotating shaft bearing is a contact bearing, and the stator bearing is a non-contact bearing; the stator bearing sleeves the rotating shaft bearing; and a gap is reserved between the inner wall of the stator bearing and the outer wall of the rotating shaft bearing. The thrust bearing comprises a foil, an elastic body and a thrust bearing shell. The thrust bearing shell is a disc type shell with a center through hole; at least one end face in the thrust bearing shell is fixedly provided with the foil through the elastic body; and the side wall of the thrust bearing shell is provided with a thrust bearingair inlet. The technical problems that an existing contact type bearing is high in dependence on a lubricating agent, and the friction force between the existing non-contact type bearing and the rotating shaft rotating at a high speed is too large can be solved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a combined bearing. Background technique [0002] Theoretically, the thicker the diameter of the shaft, the greater the load it can withstand, and the greater the critical speed, but this will increase the DN value of the bearing that matches it, requiring higher performance lubricating oil , otherwise it will cause bearing wear, shaft jamming and other failures. The DN value is a reference value for selecting rolling bearing lubricating oil, where D is the diameter of the bearing, and N is the relative speed of the inner and outer rings of the bearing. Bearings with a high DN value have higher requirements for grease or lubricating oil adhesion, working life, and working temperature, and the price of such lubricating grease or lubricating oil is usually higher. [0003] For non-contact bearings, such as radial air bearings, it relies on the compressed air between the shaft an...
