Description

Technical Field

[0001] This invention relates to the field of bearing technology, and in particular to an integrated corrugated hydrodynamic air suspension radial thrust bearing. Background Technology

[0002] Bearings are core components of modern mechanical equipment. Essentially, they are key components in mechanical systems used to support rotating shafts or moving parts. Their core function is to bear loads and ensure the smooth, low-friction operation of moving parts. Different bearings have different application scenarios. Among them, air suspension bearings can form a load-bearing air film through gas, eliminating direct contact between metals, making them irreplaceable in high-precision, high-speed, and clean environments. Traditional air suspension bearings have a relatively simple structure, only providing radial or thrust effects. Furthermore, their mounting methods are traditional, making disassembly and maintenance time-consuming and cumbersome. When misalignment occurs during use, it cannot be corrected in time, affecting their operation. Summary of the Invention

[0045] The specific usage and function of this embodiment are as follows: During installation, the locking screw 201 can be controlled to pass through the mounting hole 103 and be inserted into the connecting support ring 301. Before insertion, the inner sliding plate 501 and the sliding rod 504 need to be pressed down and slid by the pressing plate 502. The spring A503 on the surface of the sliding rod 504 is compressed and contracts, and the sliding rod 504 is pressed down and inserted into the top slot 202 of the corresponding locking screw 201. During insertion, the two sets of limiting posts 5064 on the side of the sliding rod 504 are in the guide groove 203. During the insertion process, the limiting posts 5064 Under compression, the device gradually contracts inward towards the support column 5061. Upon full insertion, the limiting column 5064 slides to the locking hole 204. The spring C5063 on one side of the support column 5061 pushes elastically, controlling the limiting column 5064 to insert into the locking hole 204, forming a limiting connection. Subsequently, the pressing control on the pressing plate 502 is released, and the sliding insertion rod 504 receives elastic push from the surface spring, causing the locking screw 201 connected to it to slide, pushing the top of the locking screw 201 into the threaded hole of the tightening rotating column 405. After multiple sets of locking screws 201 are inserted, the electrically controlled rotary control device can be inserted. The main control rod 403 is rotated via an electrically controlled rotary control device. Since the main control rod 403 has gears on its surface that mesh with the drive gear ring 402, it rotates the gear ring 402 and the rotating ring 401, thereby controlling the simultaneous rotation of multiple sets of tightening rotating columns 405. At this time, the locking screw 201 is pulled by a spring and inserted into the threaded hole of the tightening rotating column 405. The rotation of the tightening rotating column 405 controls the sliding of the locking screw 201, completing the fastening connection. During use, after gas injection, the integrated corrugated plate 102 and... The grooved surface of the bearing disc 101 provides radial and thrust protection. During disassembly, the tightening rotating column 405 can be controlled to rotate in the opposite direction, pushing the locking screw 201 to slide and separate. Subsequently, the pressing frame 5051 is controlled to slide, and the pull rope 5053 is controlled to pull the two sets of limiting columns 5064 to slide inward, releasing the limiting connection with the locking screw 201 and completing the disassembly. During bearing operation, if the internal shaft deviates, multiple sets of telescopic control push rods 602 can be activated simultaneously, pushing the contact wheel 604 to slide inward from multiple directions to position and move the internal shaft.
