[0002] The core function of axial thrust bearings is to bear axial loads and limit axial displacement of the shaft system, while achieving efficient transmission of rotating parts. They are usually composed of a shaft ring, a seat ring and rolling elements. The inner diameter of the shaft ring is smaller than that of the seat ring. Traditional thrust bearings are widely used due to their simple structure and other advantages. During the actual installation of current axial thrust bearings, workers are required to accurately distinguish between the shaft ring and the seat ring, and ensure that the shaft ring is connected to the rotating shaft. Otherwise, reverse installation will easily cause hidden dangers such as dry grinding. It is not convenient to independently set the shaft ring and seat ring after installation to prevent reverse installation and ensure installation quality. Repair and replacement are time-consuming and labor-intensive. At the same time, the service life consistency is poor, which makes it inconvenient for rotation and inspection and observation of rolling element wear.

The roller positioning member 2 is used in conjunction with the bearing mounting member 1, which can facilitate the staff to quickly perform precision maintenance work, and can facilitate a more intuitive understanding of whether the ball 103 rotates normally. The detection is simple, and the thrust bearing can be used to be easy to disassemble to quickly assist the staff in maintenance, which is lower in cost and more intuitive. Rotate the upper bearing ring 101 to observe whether the prompt mark 104 rotates around the prompt groove 2012. Once the prompt mark 104 rotates, it means that a circle of balls 103 can roll normally and rotate with reduced resistance.

[0023] Among them, the shaft control part 3 includes: a closing cover 301, a pressing stud 302 and a positioning stud 303, the closing covers 301 are fixedly installed on the two bearing rings 101 respectively, and the two closing covers 301 are respectively threaded with a circle of pressing studs 302, and the ends of the circle of pressing studs 302 are respectively tapered structures; the closing cover 301 is threaded with a positioning stud 303, and the ends of the positioning studs 303 are tapered structures; the pressing stud 302 and the positioning stud 303 are respectively provided with hexagonal holes on the top; the driving part 4 includes: a driving ring 401 and a positioning groove 402, the two bearing rings 101 are respectively rotatably sleeved with the driving rings 401, and the two driving rings 401 are respectively provided with a circle of positioning grooves 402; a circle of positioning grooves 402 and a circle of pressing studs 302 on the same side are staggered; the end of the positioning stud 303 is inserted into the driving ring 401; the positioning stud 303 is used to The driving ring 401 is positioned; the positioning groove 402 is a conical groove; the driving member 4 also includes: a fitting magnet 403, a circle of V-shaped grooves is provided on the driving ring 401, and the circle of V-shaped grooves on the driving ring 401 are respectively used to squeeze the clamping member 5; a circle of fitting magnets 403 is fixedly embedded on the driving ring 401, and a circle of fitting magnets 403 are respectively located on both sides of the circle of V-shaped grooves on the driving ring 401; the clamping member 5 includes: a clamping block 501 and an expansion inclined surface 5011, a circle of clamping blocks 501 are respectively slidably inserted on the two bearing rings 101, and the ends of the two circles of clamping blocks 501 are respectively arc-shaped structures; the tail ends of the two circles of clamping blocks 501 are respectively provided with expansion inclined surfaces 5011, and the expansion inclined surfaces 5011 are respectively attached to the V-shaped grooves opened on the driving ring 401 on the same side; the two circles of fitting magnets 403 magnetically adsorb the two circles of clamping blocks 501; the clamping blocks 501 are used to squeeze the rotating shaft inward;The bottom of the closing cover 301 is attached to the clamping block 501 and the drive ring 401, and a clamping member 5 is adopted. The clamping member 5 is used in conjunction with the drive member 4 to control the clamping shaft, that is, the rotating end. This structure uses the method of providing clamping members 5 on the two bearing rings 101 respectively. The two bearing rings 101 do not need to be distinguished. After installation, the staff can independently control and determine that any one of the two bearing rings 101 is connected to the shaft through the clamping member 5 to achieve independent setting, avoiding the need for traditional thrust bearings to ensure that the shaft ring is connected to the shaft, otherwise it is easy to cause dry grinding and other hidden dangers if it is installed upside down. Once the staff installs it incorrectly, it is time-consuming and labor-intensive to disassemble it. At the same time, thrust bearings often need to be used in conjunction with traditional ball bearings. The disassembly workload is large, and dry grinding is also prone to cause dry grinding and other hidden dangers. This structure is compact and easy to operate. By directly placing any bearing ring 101 on the installation part The stationary end, such as the shaft seat, is directly sleeved on the rotating end, that is, the shaft, without distinguishing. Then, the positioning stud 303 on one side of the shaft end is rotated to release the squeeze of the drive ring 401, and then the pressing stud 302 is tightened one circle. The pressing stud 302 and the positioning groove 402 are misaligned. When the pressing stud 302 is tightened one circle, the conical inclined surface structure at the end of the pressing stud 302 presses the positioning groove 402, so that the driving ring 401 is rotated. The V-shaped groove on the driving ring 401 squeezes the expansion inclined surface 5011, driving the clamping block 501 to move inward to clamp the shaft end. The operation is simple and convenient. Similarly, after the staff clamps and installs the shaft end, if the staff mistakenly tightens the clamping block 501 on the bearing ring 101 on the delicate end, the rotating end cannot rotate normally. Adjustment is simpler and more direct when the staff needs to.

[0024] Embodiment 2, on the basis of embodiment 1, the anti-slip control part 6 includes: an anti-slip column 601, a circle of anti-slip columns 601 are respectively slidably inserted on the two closing covers 301, and the circle of anti-slip columns 601 are respectively aligned with the circle of pressing studs 302 and the positioning studs 303 on the same side; the two circles of anti-slip columns 601 are used to stop the two circles of pressing studs 302 and the two positioning studs 303; the anti-slip control part 6 also includes: a spring 602, the tails of the two circles of anti-slip columns 601 are respectively fixed with springs 602, and the two circles of springs 602 are respectively located inside the two bearing rings 101; the ends of the two circles of springs 602 are respectively connected The anti-slip control part 6 connected to the inside of the bearing ring 101 can be used to control the anti-loosening limit of the pressing stud 302 after the pressing stud 302 is tightened, which can improve the stability of the pressing stud 302 after installation, reduce the safety hazard of the pressing stud 302 being threaded off, realize automatic limit control, and also serve to remind the staff to tighten the pressing stud 302 into place. The structure is simple and reasonable. When the pressing stud 302 is rotated and pressed into place, the anti-slip column 601 loses its cover, and under the extrusion of the spring 602, the anti-slip column 601 can be extended to prevent the pressing stud 302 from slipping off.

[0025] The working principle of this embodiment is as follows: first, any one bearing ring 101 is directly placed on the stationary end of the mounting part, such as the shaft seat, and similarly, the other bearing ring 101 is directly sleeved on the rotating end, that is, the rotating shaft, without distinguishing, and manually using a hexagonal wrench to connect the hexagonal holes on the top of the pressing stud 302 and the positioning stud 303 to operate and rotate, rotate the positioning stud 303 on one side of the rotating shaft end, release the squeeze drive ring 401, and then tighten the pressing stud 302 one circle, and use the misalignment of the pressing stud 302 and the positioning groove 402. When the pressing stud 302 is tightened one circle, the conical inclined surface structure at the end of the pressing stud 302 will pressurize the positioning groove 402, so as to realize the toggle of the drive ring 4 01 rotates, the V-shaped groove on the drive ring 401 will squeeze the expansion inclined surface 5011, driving the clamping block 501 to move inward to clamp the shaft end. When the rotation pressing stud 302 is pressed into place, the anti-slip column 601 loses its shielding. Under the pressure of the spring 602, the anti-slip column 601 can be extended, and the stop pressing stud 302 can be pressed down. Similarly, when it is necessary to rotate the positioning stud 303 to contact the extruded drive ring 401, the anti-slip column 601 can be directly pushed inward to compress the spring 602 to release the limit. When it is necessary to understand the rotation of the ball 103, the prompt mark 104 on a circle of the ball 103 can be manually adjusted to the edge of the prompt groove 2012, and the prompt groove 2012 is kept eccentric, as shown in the attached figure. Figure 2The position shown in the figure can be rotated at this time to observe whether the prompt mark 104 rotates around the prompt groove 2012. Once the prompt mark 104 rotates, it means that a circle of balls 103 can roll and rotate normally to reduce resistance. On the contrary, if the local prompt mark 104 does not move or cannot rotate around the inside of the prompt groove 2012, it means that there is slippage or the balls 103 are severely worn. The inspection and observation are simple and accurate.
