Description

Technical Field

[0002] In the rapid development of modern industry, high-speed rotating machinery plays an indispensable core role in key fields such as aerospace, energy and power, and precision manufacturing. As the core support component of such machinery, the performance of hydrodynamic air bearings directly determines the operational stability of the entire mechanical system. Hydrodynamic air bearings use air as a lubricating medium to lift the rotor and achieve contactless suspension, which has significant advantages such as no friction, no need for lubricating oil, high temperature resistance, long service life, and clean and environmentally friendly operation.

[0003] The existing foil structure of bearings lacks effective protection and limiting mechanisms. Under the action of air film pressure generated by high-speed rotation, the corrugated elastic foil and the flat foil are prone to axial misalignment, and even local stress concentration may occur, leading to foil damage, which seriously affects the service life and operational stability of the bearing. At the same time, the assembly precision between the foil structure and the bearing housing and inner cylinder is difficult to control, and uneven gaps are prone to occur, resulting in an unbalanced air film pressure distribution, which reduces the bearing's load-bearing capacity and impact resistance.

[0016] Beneficial effects

[0017] 1. This invention, by having a protective ring frame that fits tightly against the outer side of the inner cylinder and against both sides of the flat foil and the corrugated elastic foil, can effectively limit the axial movement and protect the radial movement of the foil structure, preventing axial misalignment, edge curling, and local stress concentration damage of the foil during high-speed rotation; at the same time, the connecting groove and the outer surface of the protective ring frame are both provided with a smooth and wear-resistant coating, which can effectively reduce frictional loss during relative movement between the two.

[0018] 2. This invention, through the cooperation of auxiliary grooves and connecting protrusions, as well as guide strips and guide grooves, can accurately guide and position the inner cylinder, preventing the inner cylinder from shifting when the rotor rotates at high speed; at the same time, by using fixed ring A and fixed ring B and the supporting spring between them, the elastic buffering effect of the spring can absorb the vibration during operation, further stabilize the position of the inner cylinder, ensure uniform and stable air film thickness, and reduce rotor vibration and operating noise.

[0019] 3. In this invention, the elastic damping pads set at the crests of the corrugated elastic foil are made of high-temperature resistant elastic material and are tightly bonded to the flat foil. This effectively enhances the damping characteristics of the bearing, suppresses self-excited oscillations during high-speed rotor operation, and prevents bearing instability. At the same time, the elastic damping pads can buffer the contact stress between the flat foil and the corrugated elastic foil, reducing the fatigue wear of the corrugated elastic foil. Combined with the annular array arrangement of the corrugated elastic foil, the air film pressure distribution is further optimized.

[0020] 4. This invention, by setting a symmetrical installation mechanism and an auxiliary seat, enables the installation seat to be quickly snapped into the auxiliary seat, and the connecting block to be snapped into the connecting hole by means of the elasticity of the spring and its own inclined side, thereby achieving rapid fixation of the installation seat and enabling rapid installation of the shielding ring frame; at the same time, the reinforcing ring is snapped into the reinforcing groove, which can improve the connection between the shielding ring frame and the bearing housing, and ensure the overall assembly accuracy of the bearing.

[0021] 5. In this invention, the inner ring of the inner cylinder is set as a conical structure, and the guide grooves are spiral and distributed in a ring array on the inner wall of the inner cylinder. This can guide the air to flow in the spiral direction when the rotor rotates at high speed, accelerate the formation speed of the air film, and enhance the stability of the air film, avoiding local vacuum or pressure change in the air film. At the same time, the spiral guide grooves can guide the airflow generated during the rotor rotation to be discharged in an orderly manner, reducing vibration and noise caused by airflow turbulence.

[0049] The specific usage and function of this embodiment are as follows: In this invention, the flat foil 301 is attached to the outside of the inner cylinder 201. The inner cylinder 201 with the foil structure 3 assembled is coaxially inserted into the bearing housing 1, so that the connecting protrusion 202 is inserted into the connecting seat 108 through the guide groove 203 and the guide strip 109, thus achieving the initial positioning of the inner cylinder 201. Then, the guide rod 401 is inserted into the guide hole 205, so that the protective ring frame 402 is attached to the outside of the inner cylinder 201, while ensuring that the two sides of the protective ring frame 402 are tightly attached to the two sides of the flat foil 301 and the corrugated elastic foil 302. The inner cylinder 201 and the protective component 4 are fitted together to achieve limiting protection for the foil structure 3. The mounting base 501 is aligned with the C-shaped auxiliary base 102. With the help of the beveled structure at the end of the connecting block 502, the mounting base 501 is pushed into the auxiliary base 102. Under the squeezing action of the auxiliary base 102, the connecting block 502 compresses the spring and retracts into the mounting base 501. When the mounting base 501 is fully inserted into the auxiliary base 102, the connecting block 502 resets under the elastic force of the spring and is inserted into the connecting hole 103. At the same time, the positioning plate 504 is in the positioning groove 503. The inner sliding action guides and limits the connecting block 502, preventing it from shifting. At this time, the reinforcing ring 602 is precisely embedded in the reinforcing groove 1010, completing the assembly of the shielding structure 6 and the mounting mechanism 5. The protective ring frame 402 is then embedded in the connecting groove 603, ensuring a tight fit between the inner wall of the connecting groove 603 and the smooth, wear-resistant coating on the outer surface of the protective ring frame 402. The bearing is then fixed to the target equipment's installation position via the flange 101 on the outside of the bearing housing 1, ensuring a secure and stable installation. According to the rotor specifications, the rotor is inserted into the tapered inner ring of the inner cylinder 201. After assembly, the equipment is started to rotate the rotor. When the rotor rotates at high speed, the spiral annular array guide grooves 204 on the inner wall of the inner cylinder 201 guide the air to flow in the spiral direction, accelerate the formation of the air film and enhance the stability of the air film, and at the same time discharge turbulent airflow. With the help of the corrugated elastic foil 302 and the elastic damping pad, the rotor self-excited oscillation is suppressed, ensuring that the air film pressure distribution is uniform. During operation, the support spring 106 absorbs the vibration of the equipment and further stabilizes the position of the inner cylinder 201. The protective ring frame 402 and the shielding structure 6 jointly protect the foil structure 3 to avoid axial misalignment and wear.
