Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to an integrated sealed thrust ball bearing. Background Art
[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Thrust ball bearings are designed to withstand thrust loads when running at high speeds. They are composed of washer-shaped rings with raceway grooves for ball rolling. Thrust ball bearings can only withstand axial loads but not radial loads. Thrust ball bearings are mainly composed of shaft rings, seat rings, and rolling elements.
[0003] At present, the rolling elements, shaft rings and seat rings of existing thrust ball bearings are independent of each other and have poor sealing performance. Dust or tiny particles are easily allowed to enter the thrust ball bearings during operation, resulting in increased wear when the balls move and shortening the service life. In this regard, we propose an integrated sealed thrust ball bearing to solve the above problems. Utility Model Content

[0006] A shaft ring and a seat ring, the seat ring is arranged on one side of the shaft ring, a fixing frame is arranged between the shaft ring and the seat ring, a plurality of annular equidistantly distributed rolling balls are rollingly mounted on the fixing frame, a first retaining ring is arranged at the outer edge of a side wall of the shaft ring close to the seat ring, a second retaining ring is arranged at the inner edge of a side wall of the shaft ring close to the seat ring, the first retaining ring and the second retaining ring are both slidably connected to the seat ring, a snap-fit assembly is arranged on the seat ring, the number of the snap-fit assemblies is two, and the two snap-fit assemblies are symmetrically arranged on the seat ring.
[0007] Preferably, the clamping assembly includes a slider and an elastic spring, the seat ring is provided with two symmetrically arranged sliding grooves, the slider is slidably connected in the sliding grooves, one end of the slider is fixedly welded with a clamping block, the clamping block passes through the seat ring and is slidably connected to the seat ring, an annular clamping groove is provided on the inner wall of the first retaining ring, and the clamping block is movably inserted in the annular clamping groove.
[0008] Preferably, a through hole is opened on a side wall of the slider away from the clamping block, a sliding rod is slidably connected in the through hole of the slider, one end of the sliding rod away from the slider is fixedly welded to the inner wall of the sliding groove, and the elastic spring is sleeved on the sliding rod.
[0009] Preferably, a pull block is fixedly welded on the sliding block.
[0010] Preferably, the first retaining ring and the second retaining ring are both integrally formed with the shaft ring.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model uses the first retaining ring and the second retaining ring to enclose the fixing frame and the plurality of balls between the shaft ring and the seat ring, thereby improving the overall sealing performance and preventing dust or tiny particles from entering the interior of the thrust ball bearing during operation, which causes increased wear when the balls move and shortens the service life. The seat ring is installed between the first retaining ring and the second retaining ring by providing a clamping assembly, which ensures that the shaft ring can rotate normally while the seat ring will not fall off easily. When the seat ring needs to be removed, it is only necessary to pull the two pulling blocks toward each other at the same time, so that the slider slides in the slide groove and drives the clamping block to disengage from the annular clamping groove, thereby improving the convenience of removing the seat ring and making it convenient to add lubricating oil to the balls inside.

[0021] The clamping assembly includes a slider 8 and an elastic spring 12. The seat ring 2 is provided with two symmetrically arranged sliding grooves 7. The slider 8 is slidably connected in the sliding grooves 7. A clamping block 9 is fixedly welded at one end of the slider 8. The clamping block 9 penetrates the seat ring 2 and is slidably connected to the seat ring 2. An annular clamping groove 10 is provided on the inner wall of the first retaining ring 5. The clamping block 9 is movably inserted in the annular clamping groove 10. The seat ring 2 can be limited between the first retaining ring 5 and the second retaining ring 6 by the cooperation of the set clamping block 9 and the annular clamping groove 10.
[0022] A through hole is provided on one side wall of the slider 8 away from the clamping block 9, and a slide rod 11 is slidably connected in the through hole of the slider 8. One end of the slide rod 11 away from the slider 8 is fixedly welded to the inner wall of the slide groove 7, and the elastic spring 12 is sleeved on the slide rod 11. The elastic force of the elastic spring 12 acts on the slider 8, so that the slider 8 can drive the clamping block 9 to remain inserted in the annular clamping groove 10.
