DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 6 The utility model provides a technical solution: a high-load-bearing deep groove ball bearing, comprising a protective ring 1, an inner ring of the protective ring 1 is provided with a slide groove 2, the interior of the slide groove 2 is slidably connected to a bearing body 3, and an adjustment component 4 is provided in the middle of the bearing body 3.
[0025] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the bearing body 3 includes a slip ring 301 slidably connected to the middle of the slide groove 2, the slip ring 301 is fixedly connected to the outer ring of the outer ring 302, the inner ring of the outer ring 302 is respectively provided with two engaging grooves 303 and an adjusting groove 304, the two engaging grooves 303 are each provided with a supporting ring 305, a plurality of balls 306 are fitted in the middle of the adjusting groove 304, two retaining frames 307 are provided on both sides of the plurality of balls 306, and one side of the plurality of balls 306 is fitted with the middle of the inner ring 308.
[0026] In this embodiment, Figure 3 and Figure 4 As shown, the outer ring of the inner ring 308 also has two snap-fit grooves 303, and the inner diameters of the two snap-fit grooves 303 are consistent with the outer diameter of the support ring 305; so that the support ring 305 is tightly attached to the inner wall of the snap-fit groove 303, which can play a sealing role, prevent external dust from entering the interior of the bearing, and at the same time enhance the radial bearing capacity of the bearing.
[0027] In this embodiment, Figure 3 As shown, a rolling groove 309 is provided in the middle of the outer ring of the inner ring 308, and the curvature of the rolling groove 309 is consistent with the curvature of the spherical surface of the ball 306, and the curvature of the adjusting groove 304 is smaller than the curvature of the spherical surface of the ball 306; and the width of the adjusting groove 304 is larger than the diameter of the ball 306; the rolling groove 309 can make the ball 306 always fit with the outer ring of the inner ring 308 and move with the inner ring 308, and the adjusting groove 304 can make the ball 306 move to a certain extent in the adjusting groove 304, so as to adjust the coaxiality error between the inner ring 308 and the connecting shaft.
[0028] In this embodiment, Figures 4 to 6 As shown, the adjustment assembly 4 includes four groups of fixed rings 401 fixedly connected to the inner ring of the inner ring 308, three groups of connecting rings 402 are fixedly connected between the four groups of fixed rings 401, and the inner rings of the three groups of connecting rings 402 are fixedly connected to the outer ring of the adjustment ring 403.
[0029] In this embodiment, Figures 4 to 6 As shown, four holes are opened on the two middle fixing rings 401 of the fixing ring 401, and reinforcing columns 404 are passed through the four holes. The reinforcing columns 404 are fixedly connected between the two outermost connecting rings 402. This structure can make the connection between the adjusting ring 403 and the inner ring 308 more stable. When a coaxiality error occurs between the adjusting ring 403 and the middle connecting shaft, the connecting shaft will squeeze one side of the adjusting ring 403 and cause the adjusting ring 403 to shift. At this time, the adjusting ring 403 drives the inner ring 308 to shift through the fixing ring 401 and the connecting ring 402, thereby driving the ball 306 to move in the adjusting groove 304 to adapt to the adjustment of the coaxiality error, and by setting the sliding groove 2 and the sliding ring 301, the bearing can continue to rotate.
[0030] When the utility model is in use, the working process is as follows:
[0031] like Figures 1 to 6 As shown, first, the rotating shaft to be installed with the bearing is fixed to the inner ring of the adjusting ring 403. When a coaxiality error occurs between the rotating shaft and the adjusting ring 403, the rotating shaft will squeeze one side of the adjusting ring 403, causing the adjusting ring 403 to deviate. At this time, the adjusting ring 403 synchronously drives the connecting ring 402 and the reinforcing column 404 to move, thereby driving the fixing ring 401 to deviate. The fixing ring 401 drives the inner ring 308 to deviate. Since the ball 306 is slidably connected in the rolling groove 309 of the outer ring of the inner ring 308, Therefore, the inner ring 308 drives the ball 306 to deviate synchronously, so that the ball 306 can move in the adjustment groove 304, thereby adjusting the coaxiality error between the bearing and the rotating shaft; by setting the slide groove 2 and the slide ring 301, the bearing can continue to rotate during this process; when the bearing is subjected to radial pressure, the protective ring 1, the outer ring 302 and the inner ring 308 can share part of the pressure, and the support ring 305 between the inner ring 308 and the outer ring 302 can also play a supporting role to enhance the bearing capacity of the utility model. It is worth noting that the thickness of the support ring 305 is smaller than the width of the engaging groove 303. This structure can prevent the inner ring 308 from being hindered by the support ring 305 when it deviates, and prevent the support ring 305 from locking the inner ring 308 and the outer ring 302.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
