Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0032] Such as Figure 1-4 As shown, a bearing includes a stator 2 and a rotor 1 arranged in the stator 2;

[0033] The inner wall of the stator 2 is provided with an annular protrusion along the circumferential direction, and the outer wall of the rotor 1 is provided with an annular groove matching the annular protrusion.

[0034] The bearing can be a hydrostatic bearing or a conventional oil-lubricated bearing. The rotor 1 has a structure with a large diameter at both ends and a small diameter in the middle, that is, an annular groove is set in the middle, and a matching annular protrusion is provided on the stator 2. This structure cannot be produced separately by the stator 2 and the rotor 1. The preparation method needs to be integrally formed. Preferably, the stator 2 and the rotor 1 are int...

Abstract

The invention relates to the technical field of bearings, in particular to a bearing and a manufacturing method thereof. The bearing comprises a stator and a rotor, wherein the rotor is arranged inside the stator; annular bulges which are arranged in a circumferential direction are arranged on the inner wall of the stator; annular grooves matched with the annular bulges are formed in the outer wall of the rotor. Diameters of two ends of the bearing provided by the invention are larger than that of the middle part, precise radial support can be achieved after the rotor and the stator are integrally molded and used, precise axial direction can be achieved as well, the bearing is simple in structure, furthermore production and manufacturing processes can be simple, and the production efficiency can be relatively high.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing and a manufacturing method thereof. Background technique [0002] Aerostatic bearings refer to plain bearings that use a gas (usually air, but possibly other gases) as a lubricant. Air is less viscous than oil, high temperature resistant, and non-polluting, so it can be used in high-speed machines, instruments and radioactive devices, but its load capacity is lower than that of oil. Bearings fall into three main categories: aerostatic bearings, aerodynamic bearings, and extruded film bearings. In general industry, bearings are widely used. [0003] Aerostatic bearings provide extremely high radial and axial rotational accuracy, and since there is no mechanical contact, wear is reduced to a minimum, thus ensuring that the accuracy remains constant at all times. The low shear force inside the aerostatic bearing can provide extremely high speed while minimizing power l...
