Embodiment Construction

[0033] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] Embodiment 1 of the air bearing of the present invention, such as figure 2 and image 3 As shown, it includes a housing 2 and a bearing base 3 arranged in the housing 2 .

[0035] The bearing matrix 3 is first made of metal wire as a raw material through a three-dimensional weaving process to make a plate material, and then the plate material is bent and deformed and then butted end-to-end. There are a large number of pores between the metal wires in the three-dimensional braided structure, and these pores are regularly arranged on the plate material, which can ensure the porosity and air permeability requirements of the air bearing. Tell me more.

[0036] The two ends of the produced plate material are butt ends, and the end faces of the butt ends are butt surface 5, and the butt surface 5 is an inclined surface that can be joine...

Abstract

The invention relates to the field of sliding bearings, in particular to an air bearing and a bearing matrix thereof and a manufacturing method. The air bearing comprises a shell and the bearing matrix arranged in the shell, the bearing matrix is manufactured in the mode that three-dimensionally braided plate block materials are bent and deformed and then connected end-to-end, the butt-joint surfaces are fixed through welding, and multiple strength strengthening points which are arranged at intervals in the circumferential direction and used for strengthening the strength of the bearing matrixare arranged on the circumference of the bearing matrix through a local heat treatment method. A large quantity of pores exist among metal wires in the three-dimensionally braided structure, influences of cutting machining on the material porosity can be avoided through overall sequential braided molding and welding after limiting and deforming, and meanwhile influences on the stability of the bearing matrix of the air bearing is avoided.

Description

technical field [0001] The invention relates to the field of sliding bearings, in particular to an air bearing, a bearing matrix and a manufacturing method thereof. Background technique [0002] The three-dimensional braided structure is finally formed by interweaving the metal wires participating in the movement through position transformation in space through a specific weaving process. like figure 1 As shown, there are a large number of pores 8 between the metal wires 7 in the three-dimensional braided structure 6, which is conducive to the infiltration and storage of lubricating substances. At the same time, the three-dimensional braided structure 6 is produced by the regular periodic weaving motion of the metal wires 7, and the final material is The internal structure of the pores 8 is regular, which facilitates the establishment of a mathematical model and accurate theoretical calculation of various properties of the material. Moreover, the three-dimensional braided ...
