Description

Technical Field

[0001] The utility model relates to the technical field of air suspension bearings, in particular to an installation and positioning structure of an air suspension bearing. Background Art

[0002] An air suspension bearing is a non-contact bearing that supports a rotating shaft by generating an air film, thereby achieving suspension and rotation of the rotating shaft. This bearing eliminates the physical contact in traditional bearings, avoids friction and wear between the bearing and the shaft, and thus improves the operating efficiency and life of the rotating shaft. Existing air suspension bearings, during use, usually weld or bolt a baffle or retaining ring on the bearing mounting surface to clamp the radial air bearing through the baffle or retaining ring to prevent it from radial displacement. Since the retaining ring is installed with one or more parts, the process complexity is increased, thereby increasing the failure rate. Therefore, we propose an installation and positioning structure for an air suspension bearing to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the existing air suspension bearings, a baffle or retaining ring is usually welded or bolted to the bearing mounting surface to clamp the radial air bearing through the baffle or retaining ring to prevent it from radial displacement. Since the retaining ring is installed with one or more parts, the process complexity is increased, thereby increasing the failure rate.

[0005] Preferably, after the foil wave plate is installed into the shaft sleeve, a pin is driven into the pin hole, and the bearing foil is squeezed with the help of the notch at one end to position and fix it, which reduces the installation time, ensures the precise position of the foil wave plate in the shaft sleeve, effectively prevents the risk of bearing failure caused by displacement of the foil wave plate during operation, enhances the stability of the bearing during operation, and reduces the wear of the foil wave plate during operation, prolongs the service life of the bearing, and uses the pin for plugging and fast installation and fixing, which is convenient for future maintenance and replacement, and improves the simplicity and efficiency of installation. By using pin positioning, the complexity of the bearing design can be reduced, the bearing structure is simpler, and the failure rate of the bearing is reduced. At the same time, the pin connection sleeve is movably fixed to the outer wall of the shaft sleeve, and can be disassembled and adjusted according to usage. It can be removed when not in use, reducing the installation of parts, simplifying the structure of the bearing, reducing the complexity of the production process, and reducing production costs.

[0006] Preferably, the installation and positioning component includes a flat wave plate, a foil wave plate and a pin hole. The inner wall of the sleeve is provided with a foil wave plate, and multiple groups of pin holes are opened around the interior of the sleeve. A notch is opened at one end of the pin hole. After the foil wave plate is installed into the interior of the sleeve, the pin is driven into the pin hole, and the bearing foil is squeezed with the help of the notch at one end for positioning and fixing. This reduces the installation time, ensures the precise position of the foil wave plate in the sleeve, effectively prevents the risk of bearing failure caused by displacement of the foil wave plate during operation, enhances the stability of the bearing during operation, and reduces the wear of the foil wave plate during operation, extending the service life of the bearing.

[0008] Preferably, the auxiliary components include a ferrule, a connecting buckle and a pin. The ferrule is located at the outer end of the sleeve. The interior of the ferrule is hollow. The outer wall of the ferrule is symmetrically provided with stepped grooves. By adopting a hollow ferrule to be positioned on the outer wall of the sleeve, the weight of the parts is reduced. After the weight is reduced, the stress on the bearing is reduced, thereby ensuring the stable operation of the bearing and extending the service life of the bearing.

[0009] Preferably, two sets of connecting holes are opened inside the stepped groove, and support rings are provided inside the connecting holes. The shaft sleeve is fixed by inserting screws into the connecting holes to prevent radial displacement, thereby ensuring the accurate position of the bearing, reducing the potential risks caused by changes in the bearing position during operation, and improving operational safety.

[0022] See also Figure 1-2In this embodiment, the installation and positioning component 2 includes a flat wave plate 201, a foil wave plate 202 and a pin hole 203. The inner wall of the sleeve 1 is provided with a foil wave plate 202, and the interior of the sleeve 1 is surrounded by a plurality of pin holes 203. A notch is provided at one end of the pin hole 203. After the foil wave plate 202 is installed into the interior of the sleeve 1, a pin is driven into the pin hole 203, and the bearing foil is squeezed with the help of the notch at one end for positioning and fixing. This reduces the installation time, ensures the accurate position of the foil wave plate 202 in the sleeve 1, and effectively prevents the foil wave plate 202 from shifting during operation. The risk of bearing failure is reduced, the stability of the bearing during operation is enhanced, and the wear of the foil wave plate 202 during operation is reduced, the service life of the bearing is extended, and the pins are used for plugging and fast installation and fixing, which is convenient for future maintenance and replacement, and improves the simplicity and efficiency of installation.
