[0002] Spherical roller bearings, also known as outer ring bearings, are characterized by their spherical outer diameter surface, which fits into the corresponding concave spherical surface of the bearing housing, serving a self-aligning function. The internal structure of spherical roller bearings is similar to that of deep groove ball bearings, with rolling elements typically being steel balls (i.e., rolling elements). These balls, as rolling elements, play a crucial role in transmitting loads and reducing friction and wear in spherical roller bearings. They enable the bearing to operate more efficiently and extend its service life.

[0003] After the existing ball bearings are produced, they need to be screened according to their diameter. The common screening method is to use screening molds with different screen hole sizes. However, this screening method has certain drawbacks. It requires frequent replacement of screening molds, which is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, those skilled in the art have provided a ball screening device for the production of spherical bearings to solve the problems mentioned in the background art. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As mentioned in the background section of this application, research has found that existing ball bearings need to be screened according to their diameter after production. The common screening method is to use screening molds with different screen hole sizes. However, this screening method has certain drawbacks. It requires frequent replacement of screening molds, which is time-consuming, labor-intensive, and inefficient.

[0028] To address the aforementioned shortcomings, this application discloses a ball bearing screening device for the production of spherical bearings, which eliminates the need for frequent replacement of screening molds, saving time and effort while improving work efficiency.

[0029] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.

[0030] Please see Figures 1-5 In this embodiment of the present invention, a ball bearing screening device for the production of spherical bearings includes: a frame 1, and a screening cylinder 2 rotatably connected to the top of the frame 1. One end of the screening cylinder 2 is provided with a material guiding assembly, and the other end of the screening cylinder 2 is provided with a driving mechanism. This invention eliminates the need for frequent replacement of screening molds, saving time and effort while improving work efficiency.

[0031] In this embodiment, the screening cylinder 2 has four parallel annular plates 3 inside, which divide the screening cylinder 2 into five sub-cylinders. Each sub-cylinder has a grid 4 fixedly connected to its outer wall, and the spacing between the five grids 4 gradually decreases from the side closest to the material guide assembly to the other side. Different sub-cylinders can screen out balls of different diameters, with the sub-cylinders closer to the material guide assembly screening out balls of larger diameter.

[0032] In this embodiment, each of the annular plates 3 is provided with a guide seat 5, and a reinforcing rod 6 is fixedly connected between the guide seat 5 and the annular plate 3. A transmission rod 8 is provided through the center of the screening cylinder 2, and the transmission rod 8 passes through the guide seat 5 and is fixedly connected to it. The two ends of the transmission rod 8 are respectively connected to the material guiding assembly and the driving mechanism. The transmission rod 8 can drive the guide seat 5 and the annular plate 3 to rotate, thereby causing the entire screening cylinder 2 to rotate. The reinforcing rod 6 can improve the connection stability between the guide seat 5 and the annular plate 3.

[0033] In this embodiment, a guide bin 7 is fixedly connected to the frame 1 below the sub-cylinder. The guide bin 7 facilitates the discharge of the balls screened by the sub-cylinder.

[0034] In this embodiment, the guiding assembly specifically includes: a feeding support frame 17 fixed to one side of the frame 1; a concave guiding plate 18 fixedly connected to the top of the feeding support frame 17; and a guiding frame 19 fixedly connected to one side of the concave guiding plate 18. The guiding frame 19 extends into the screening cylinder 2, and a rectangular groove 20 is formed on the top surface of the guiding frame 19. Inclined guide plates 21 are fixedly connected to the inner walls of both sides of the rectangular groove 20. An intermittent feeding mechanism is fixedly connected between the two inclined guide plates 21. A first rotating seat 16 is fixedly connected to one side of the top surface of the guiding frame 19, and the first rotating seat 16 is rotatably connected to one end of the transmission rod 8. The guiding assembly can quickly and effectively guide the balls to be screened into the screening cylinder 2.

[0035] In this embodiment, the intermittent feeding mechanism specifically includes: an optical shaft 22 fixed between two inclined guide plates 21; a sleeve 23 movably connected to the outside of the optical shaft 22; inclined plates 24 fixedly connected to both sides of the sleeve 23; a counterweight 26 provided below the sleeve 23; and a connecting plate 25 fixedly connected between the counterweight 26 and the bottom end of the sleeve 23. The intermittent feeding mechanism allows the balls to be gradually introduced into the screening cylinder 2, preventing too many balls from entering at once and squeezing each other across the grid 4, thus reducing the burden on the grid 4 and improving screening accuracy.

[0036] In this embodiment, the driving mechanism specifically includes: a driving support frame 9 fixed to the other side of the frame 1; a driving motor 10 fixedly connected to the top of the driving support frame 9; a gearbox 11 fixedly connected to one side of the driving motor 10; the output shaft of the driving motor 10 being driven by the gearbox 11; a driving gear 12 fixedly connected to the output shaft of the gearbox 11; a driven gear 13 rotatably connected to one side of the driving gear 12; a chain 14 drivingly connecting the driven gear 13 and the driving gear 12; a second rotating seat 15 fixedly connected to the driving support frame 9 on one side of the driven gear 13; and the other end of the transmission rod 8 passing through the second rotating seat 15 and fixedly connected to the driven gear 13. Through the driving mechanism provided in this application, the screening cylinder 2 can be driven to rotate quickly and stably by cooperating with the transmission rod 8, the first rotating seat 16, and the second rotating seat 15, thereby improving screening efficiency.

[0037] The working principle of this utility model is as follows: In use, firstly, the drive mechanism drives the screening cylinder 2 to rotate. Specifically, the drive motor 10 drives the gearbox 11 to rotate, which in turn drives the drive gear 12 to rotate. Under the transmission action of the chain 14, the driven gear 13 follows, causing the transmission rod 8 to rotate. The rotation of the transmission rod 8 drives the guide seat 5 and the annular plate 3 to rotate, thus causing the entire screening cylinder 2 to rotate. Then, the balls to be screened are fed into the guide frame 19 along the concave guide plate 18 of the guide assembly, and then enter the screening cylinder 2 through the rectangular groove 20 for screening. Since the annular plate 3 divides the screening cylinder 2 into five sub-cylinders, and each sub-cylinder has grids 4 with different spacing on its outer wall, different sub-cylinders can screen balls of different diameters during the ball screening process. The sub-cylinders closer to the guide assembly screen larger diameter balls, and the balls screened by the sub-cylinders fall onto the corresponding guide bins 7 under their own gravity, where they are discharged. It should be noted that, in order to ensure that the balls can move forward, the side of the device closest to the feed assembly will be raised before use.

[0038] As the balls pass through the rectangular groove 20, the intermittent feeding mechanism within the groove 20 allows the balls to be gradually guided into the screening cylinder 2, preventing too many balls from entering at once and squeezing each other across the grid 4. This reduces the burden on the grid 4 and improves screening accuracy. Specifically, two inclined guide plates 21, together with the sleeve 23, form a hopper to catch the balls. Most balls enter the hopper first when passing through the rectangular groove 20. When the number of balls in the hopper reaches a certain level and continues to be impacted, the hopper loses its balance with the counterweight 26 below, causing the hopper to tilt. This allows the balls in the hopper to enter the screening cylinder 2. After the balls in the hopper tilt, the hopper returns to its initial position under the action of the counterweight 26 to receive the balls. In this embodiment, the drive motor 10 is model ZH-400-S-5, and the gearbox 11 is model HD09.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
