Description

Technical Field

[0001] The utility model belongs to the technical field of bearing rings, and in particular relates to a spliced ​​automobile constant-speed drive bearing ring. Background Art

[0002] A bearing is a supporting component and a standard part used in the mechanical field. The structure of a bearing is very simple. It is generally composed of an outer ring, an inner ring, balls and a cage. The outer ring cooperates with the bearing seat hole or the housing of a mechanical component to play a supporting role. However, in some applications, the outer ring rotates and the inner ring is fixed, or both the inner and outer rings rotate. The inner ring usually fits tightly with the shaft and rotates with the shaft. The balls are evenly arranged between the inner and outer rings with the help of the cage. Its shape, size and number directly affect the bearing's load-bearing capacity and performance. The cage evenly separates the rolling elements, guides the rolling elements to move on the correct track, and improves the internal load distribution and lubrication performance of the bearing.

[0003] At present, the common outer ring structure is an integrated structure, which makes it difficult to operate when installing the ball. In addition, due to the specification restrictions of the outer ring, the specifications of the bearing are strictly restricted. In some occasions where the opening is slightly larger, it is often necessary to fill the space between the outer ring and the opening to fix the outer ring or ensure the stability of the installation of the outer ring. In addition, the filler has the problem of deformation, expansion and contraction, which leads to the problem of loose installation. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a spliced ​​automobile constant velocity drive bearing ring.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A spliced ​​automobile constant velocity drive bearing ring comprises an inner ring, wherein the inner ring is matched with a rolling ball, a retaining frame and an outer ring;

[0007] The outer ring comprises a male outer ring and a female outer ring, the male outer ring is integrally connected with a protrusion, the female outer ring is provided with a groove, the groove matches the specifications and dimensions of the protrusion, the female outer ring is symmetrically provided with threaded holes and round holes on both sides of the groove, the protrusion is provided with a through hole whose position matches the threaded hole and the round hole, the threaded hole is threadedly connected with a threaded column, and the threaded column is located inside the round hole and the through hole;

[0008] The threaded column is threadedly connected to a threaded barrel, the end of the threaded barrel is integrally connected to a rectangular block, two arc circles are symmetrically installed on the outer side of the outer ring, and the two arc circles are provided with placement grooves with specifications and sizes matching the threaded barrel and the rectangular block.

[0009] It is further defined that the rectangular block is provided with a fixing hole, the arc-shaped circle is provided with countersunk holes whose positions correspond to the number of the fixing holes, and the countersunk holes are installed with locking screws threadedly connected to the fixing holes. Such a design locks the rectangular block in the placement groove and enhances the connection effect.

[0010] It is further defined that the groove does not completely penetrate the female outer ring. Such a design can quickly make the surfaces of the male outer ring and the female outer ring on the same horizontal plane when the protrusion is placed in the groove.

[0011] It is further defined that the diameter of the threaded column is not less than one centimeter. Such a design ensures the strength of resistance to pulling and supporting.

[0012] It is further defined that the depth dimension of the groove is greater than half of the thickness dimension of the female outer ring. Such a design correspondingly ensures the thickness dimension of the bump and ensures the structural strength of the bump.

[0013] The beneficial effects of adopting the utility model are:

[0014] With the structural design of the utility model, the outer ring is formed by splicing the male outer ring and the female outer ring, so when installing the ball, it is easier to install and the technical requirements are reduced;

[0015] The structural design of the utility model is adopted, and two arc-shaped rings are added outside the outer ring, thereby adapting to the installation in the occasion where the opening size is slightly larger than the outer ring size;

[0016] By adopting the structural design of the utility model, the distance between the two arc circles can be changed by adjusting the overall length of the threaded barrel and the threaded column, thereby changing the size of the circular ring formed by the two arc circles, thereby adapting to the installation of different opening sizes and improving the installation adaptability.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a spliced ​​automobile constant velocity drive bearing ring of the utility model comprises an inner ring 1, and the inner ring 1 is matched with a rolling ball 2, a retainer and an outer ring;

[0025] The outer ring includes a male outer ring 4 and a female outer ring 5. The male outer ring 4 is integrally connected with a protrusion 6. The female outer ring 5 is provided with a groove 7. The groove 7 matches the specifications and dimensions of the protrusion 6. The female outer ring 5 is symmetrically provided with threaded holes 9 and circular holes 10 on both sides of the groove 7. The protrusion 6 is provided with a through hole 11 whose position matches the threaded hole 9 and the circular hole 10. The threaded hole 9 is threadedly connected with a threaded column 12. The threaded column 12 is located inside the circular hole 10 and the through hole 11.

[0026] The threaded column 12 is threadedly connected to the threaded barrel 13, and the end of the threaded barrel 13 is integrally connected to a rectangular block 14. Two arc circles 15 are symmetrically installed on the outside of the outer ring. The two arc circles 15 are provided with placement grooves 16 with specifications and sizes matching the threaded barrel 13 and the rectangular block 14.

[0027] In this embodiment, when a spliced ​​automobile constant velocity drive bearing ring is used, after the ball 2 and the retainer are placed on the outside of the inner ring 1, the male outer ring 4 and the female outer ring 5 are enclosed on the outside of the ball 2 through the cooperation of the protrusion 6 and the groove 7, and then the threaded column 12 is passed through the circular hole 10 and the through hole 11 and screwed into the threaded hole 9 to realize the splicing of the male outer ring 4 and the female outer ring 5. It should be noted here that if there is no need to use the arc ring 15 to expand the diameter of the outer ring, the threaded column 12 here is changed to a stop screw, then there will be no interference on the outside of the outer ring, which is not difficult for people in the relevant field to understand;

[0028] Furthermore, when the diameter of the outer ring needs to be expanded due to installation requirements, the threaded barrel 13 is screwed onto the threaded column 12, and then the rectangular block 14 at the end of the threaded barrel 13 is placed in the placement groove 16 of the arc ring 15. At this time, the arc ring 15 acts as an outer ring. Furthermore, by rotating the threaded barrel 13, the distance between the threaded column 12 and the threaded barrel 13 can be changed, thereby changing the outer diameter formed by the two arc rings 15, and then adapting to the installation of different opening sizes, thereby improving the installation adaptability.

[0029] Preferably, the rectangular block 14 is provided with a fixing hole 17, and the arc ring 15 is provided with a countersunk hole 18 whose position and number correspond to the fixing hole 17, and the countersunk hole 18 is installed with a locking screw threadedly connected to the fixing hole 17. Such a design locks the rectangular block 14 in the placement groove 16 to enhance the connection effect. In fact, the fixing method of the rectangular block 14 can also be considered according to the specific situation.

[0030] Preferably, the groove 7 does not completely penetrate the female outer ring 5. With this design, when the protrusion 6 is placed in the groove 7, the surfaces of the male outer ring 4 and the female outer ring 5 can be quickly placed on the same horizontal plane. In fact, the depth dimension of the groove 7 can also be considered according to specific circumstances.

[0031] Preferably, the diameter of the threaded column 12 is not less than one centimeter. Such a design ensures the strength of resistance to pulling and supporting. In fact, the diameter of the threaded column 12 can also be considered according to specific circumstances.

[0032] Preferably, the depth dimension of the groove 7 is greater than half of the thickness dimension of the female outer ring 5. Such a design correspondingly ensures the thickness dimension of the protrusion 6 and the structural strength of the protrusion 6. In fact, the depth dimension of the groove 7 can also be considered according to specific circumstances.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
