Description

Technical Field

[0001] The utility model relates to an auxiliary tool, in particular to an auxiliary tool for assembling a full ball angular contact bearing. Background Art

[0002] When assembling a full-fill angular contact ball bearing without a cage, first position the outer and inner rings correctly on the assembly station. Then, fill the grooves of the outer and inner rings with rolling elements until they are completely filled. For double-row bearings, an inner ring connecting ring is used to connect the two inner rings. Next, a sealing ring is installed between the inner and outer rings to create a seal and prevent the ingress of contaminants. Afterwards, an appropriate amount of grease is applied to all parts of the bearing to ensure smooth operation. Finally, a final inspection and assembly are performed to ensure that all components are correctly installed and in place.

[0003] However, since there is no retaining frame to limit the position of the rolling elements when they are loaded between the outer ring and the inner ring, the rolling elements are usually loaded one by one between the outer ring and the inner ring manually. This loading method is time-consuming and labor-intensive, and there is a problem that the rolling elements may fall to the ground due to instability in holding them firmly, resulting in the scrapping of the rolling elements. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a full ball angular contact bearing sleeve auxiliary tooling which improves the filling efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a full-ball angular contact bearing assembly auxiliary tooling, including a limiting groove for inserting and positioning the inner ring of the bearing to be assembled and an assembly groove for forming a positioning between the rolling body to be assembled and the rolling surface of the inner ring of the bearing to be assembled, the limiting groove includes a rest plane located on its bottom surface and a limiting surface extending axially perpendicular to the rest plane, the rest plane abuts against the inner ring of the bearing to be assembled to prevent axial movement of the inner ring of the bearing to be assembled, and the limiting surface abuts against the inner ring of the bearing to be assembled to prevent radial movement of the inner ring of the bearing to be assembled; the assembly groove is located axially above the limiting groove and the assembly groove includes an assembly inclined surface with one end connected to the limiting surface.

[0006] The beneficial effects of the present invention are as follows: the above-mentioned solution provides precise positioning and stable support, ensuring that the inner ring of the bearing does not move axially or radially during assembly, thereby improving the accuracy and efficiency of assembly. The abutment plane and the limiting surface of the limit groove prevent axial and radial movement of the inner ring, respectively, ensuring the correct position of the inner ring. The design of the assembly groove, especially the assembly bevel, helps guide the rolling elements to be correctly placed on the rolling surface of the inner ring, further ensuring the precise fit between the rolling elements and the inner ring. The use of this tooling simplifies the assembly process, reduces human error, improves the quality and reliability of bearing assembly, and also reduces the requirements for operating skills, making the assembly process more standardized and automated.

[0007] Furthermore, the inclination angle between the assembly inclined surface and the axial direction is such that when a limit is formed between the rolling element to be assembled and the rolling surface of the inner ring of the bearing to be assembled, the center of the rolling element to be assembled and the bottom of the rolling surface of the inner ring of the bearing to be assembled are in the same horizontal plane.

[0008] The angle of the assembly ramp in this solution ensures precise positioning between the rolling elements to be assembled and the inner ring running surface of the bearing. This design ensures that the center of the rolling elements and the bottom of the inner ring running surface are aligned during assembly, ensuring correct positioning and uniform distribution of the rolling elements. This precise positioning helps improve the bearing's load capacity and rotational accuracy, reducing the risk of wear and failure caused by improper installation. Furthermore, this design simplifies the assembly process, reduces operator skill requirements, improves assembly efficiency and reliability, and extends the bearing's service life, ensuring stable and consistent performance.

[0009] Furthermore, the inclination angle between the assembly inclined surface and the axial direction is such that when a limit is formed between the rolling element to be assembled and the rolling surface of the inner ring of the bearing to be assembled, the center circle diameter of the rolling element to be assembled is consistent with the center circle diameter of the finished bearing to be assembled.

[0010] The above solution ensures that the center diameter of the rolling elements to be assembled matches that of the finished bearing by utilizing the specific angle of the assembly ramp. This allows for more precise positioning of the rolling elements and the inner ring running surface, ensuring that the center diameter of the rolling elements matches that of the finished bearing. This precise positioning not only improves assembly accuracy but also reduces the need for rolling element position adjustments during assembly, thereby simplifying the assembly process, reducing labor intensity, and improving production efficiency. By eliminating the need for post-assembly adjustments to the rolling element position, this tooling helps minimize potential damage during assembly, extending the bearing's service life, and ensuring bearing performance and precision.

[0011] Furthermore, a through hole is provided at the center of the abutting plane, and a radial cross-sectional range formed by the through hole partially overlaps with a radial cross-sectional range of the inner ring of the bearing to be assembled abutting against the abutting plane.

[0012] A through-hole at the center of the abutment plane allows for the introduction of an adjustment mechanism during assembly. This through-hole, in conjunction with the adjustment mechanism, allows for convenient height adjustment of the inner ring of the bearing to be assembled if rolling element misalignment is detected during assembly quality inspection. This ensures that the center of the rolling element is level with the bottom of the inner ring's rolling surface, and that the center diameter of the rolling element is consistent with that of the finished bearing to be assembled. This precise adjustment capability significantly improves the accuracy and efficiency of bearing assembly, reduces rework and scrap due to misalignment, simplifies the assembly process, and reduces operator skill requirements.

[0016] The utility model embodiment of a full ball angular contact bearing sleeve auxiliary tooling Figure 1-3 As shown, the auxiliary tooling has a limiting groove 1, an assembly groove 2, and a pre-assembly groove 3 extending radially from its center toward its outer edge. The limiting groove 1 has a through hole 13, an abutment plane 11, and a limiting surface 12 extending radially from its center toward its outer edge. The radial cross-sectional area formed by the through hole 13 partially overlaps with the radial cross-sectional area where the inner ring 4 of the bearing to be assembled abuts against the abutment plane 11. Preferably, the inner diameter surface of the through hole 13 is threaded, and the corresponding adjustment mechanism (not shown) is a stud. The axial position of the inner ring 4 of the bearing to be assembled is adjusted by rotating the stud. The abutment plane 11 abuts the inner ring 4 of the bearing to be assembled, preventing axial movement of the inner ring 4. The limiting surface 12 extends axially perpendicular to the abutment plane 11 and abuts against the inner ring 4 of the bearing to be assembled, preventing radial movement of the inner ring 4.

[0017] The assembly groove 2 includes an assembly bevel 21. The inclination angle between the assembly bevel 21 and the axial direction ensures that when a limit is formed between the rolling element 5 to be assembled and the rolling surface of the inner ring of the bearing to be assembled (not shown in the figure), the center of the rolling element 5 to be assembled and the bottom of the rolling surface of the inner ring of the bearing to be assembled (not shown in the figure) are on the same horizontal plane. Here, the bottom of the rolling surface of the inner ring of the bearing to be assembled (not shown in the figure) refers to the point with the smallest outer diameter of the rolling surface of the inner ring of the bearing to be assembled (not shown in the figure); and ensures that the center circle diameter of the rolling element 4 to be assembled is consistent with the center circle diameter of the finished bearing to be assembled (not shown in the figure).

[0018] The pre-installed groove 3 is a flat placement plane, and a number of placement grooves (not shown in the figure) are arranged around the pre-installed groove 3 for the rolling body 5 to be assembled to form a preliminary positioning. The placement grooves are arc-shaped grooves so as to prevent the rolling body 5 to be assembled from rolling when the inner ring 4 of the bearing to be assembled has not yet been inserted into the limit groove 1.

[0019] The assembly process of this embodiment is as follows: the inner ring 4 of the bearing to be assembled is inserted into the limiting groove 1 to form axial and radial limitations; the rolling elements 5 to be assembled are then slid down the assembly inclined surface 21 until the full sphere distribution is achieved; finally, the auxiliary tooling together with the inner ring 4 of the bearing to be assembled and the rolling elements 5 to be assembled are turned over, the auxiliary tooling is removed and covered with the outer ring of the bearing to be assembled (not shown in the figure) to complete the assembly of the full sphere angular contact bearing.

[0020] The above embodiment is only one preferred embodiment of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
