Description

Technical Field

[0001] The present invention relates to the technical field of bearings, and in particular to a bearing processing method and system. Background Art

[0002] During the processing of the wheel hub inner ring bearing, the inner ring and flange are connected by an interference fit, but the connection reliability is low. Therefore, a crimping process is used to further connect the flange and inner ring. This process curls the upper part of the flange, changing its shape and position, so that the flange and inner ring fit tightly together, forming a secure connection structure. This satisfies the wheel hub inner ring bearing's functional requirements such as load bearing and torque transmission during subsequent use, thereby ensuring the normal operation and product quality of the wheel hub inner ring bearing.

[0003] However, if the correct processing parameters are not accurately obtained during the crimping process, insufficient inner ring locking force may occur during the crimping process, resulting in an unstable connection between the flange and the inner ring, affecting the overall performance of the wheel hub inner ring bearing. Alternatively, excessive tension may occur, causing excessive deformation of the inner ring and compromising its structural stability. Both insufficient locking force and excessive tension can cause the balls in the inner ring to loosen, thus affecting the bearing's structural stability. Summary of the Invention

[0015] The second backing ring and the other inner ring detection ring are sequentially sleeved on the flange unit and subjected to extrusion and crimping so that the tensioning force of the inner ring detection ring reaches a set tensioning force, thereby obtaining a second crimping force F2;

[0016] Based on F2>F1, the inner ring unit and the flange unit are crimped with a set crimping force F0; wherein F2>F0≥F1.

[0017] In some embodiments, H0+H2≤1.05×H.

[0018] In some embodiments, based on F2 ≤ F1 , an exception is issued for the first crimping force F1 and the second crimping force F2 .

[0019] In a second aspect, the present invention provides a bearing processing system, which is applied to a bearing processing method partially described in the first aspect; the bearing processing system comprises:

[0020] A press-fit assembly comprising a support unit, a press-fit unit, and a drive unit; the press-fit unit comprising a connecting post, a positioning post, a curling groove, and a limiting portion; one end of the connecting post is connected to the drive unit, and the other end is connected to the positioning post; the drive unit drives the connecting post to move; the limiting portion and the positioning post form the curling groove;

[0023] An inner ring detection ring is obtained by cutting the abutment ring of the inner ring unit along the axial direction to obtain the inner ring detection ring;

[0029] The inner ring unit's abutment ring is cut along the axial direction to obtain an inner ring inspection ring. The first backing ring and the inner ring inspection ring are sequentially placed on the flange unit for extrusion and crimping. The sum of the inner ring inspection ring height H0 and the first backing ring height H1 is less than the inner ring unit height H. During the extrusion and crimping process, the axial pressure applied to the first backing ring, i.e., the locking force, is calculated by measuring the circumferential deformation of the first backing ring. When the locking force reaches the set locking force, the first crimping force F1 is determined. Based on F1, the inner ring unit and the flange unit are crimped with a set crimping force F0 that is greater than the first crimping force F1. This allows for precise determination of the appropriate crimping force, effectively controlling the locking force during the crimping process between the inner ring unit and the flange unit, and avoiding insufficient inner ring locking force due to inappropriate crimping force. This ultimately results in a more secure connection between the inner ring unit and the flange unit, improving the processing quality and connection stability of the wheel hub bearing.

[0039] During the wheel hub bearing manufacturing process, a crimping process is required to connect the flange unit 21 and the inner ring unit 22 into a single unit. However, before starting the crimping operation, it is crucial to properly determine the crimping process parameters. If the crimping process parameters are not selected properly, the inner ring unit 22 may not have sufficient locking force during the crimping process, resulting in a loose connection and affecting the normal performance of the wheel hub bearing. Alternatively, the inner ring unit 22 may have excessive expansion force, causing excessive deformation and loosening of the balls inside the inner ring, which in turn affects the overall quality and reliability of the wheel hub bearing.

[0040] Example 1:

[0041] To solve the above problems, this embodiment provides a bearing processing method. The bearing processing method in this embodiment involves a bearing processing system including a press-fit assembly 10, an inner ring detection ring 30, a first backing ring 40, a detection assembly, and a cutting assembly.

[0042] The press-fit assembly 10 includes a support unit 11, a press-fit unit 12, and a drive unit 13. The inner ring assembly 20 includes a flange unit 21 and an inner ring unit 22. The drive unit 13 drives the inner ring unit 22 to connect with the flange unit 21. The drive unit 13 drives the press-fit unit 12 to perform extrusion and crimping of the inner ring unit 22 and the flange unit 21. During the crimping operation, the support unit 11 provides stable support for the bearing machining process. The cutting assembly cuts the abutment ring 223 of the inner ring unit 22 along the axial direction and then removes the first backing ring 40 from the cut-off ring. This cut-off ring provides a reference for the subsequent production of the first backing ring 40 and crimping experiments. The detector is used to acquire data collected by the first and second detection heads, providing a basis for analyzing and determining relevant parameters during the crimping process.

[0043] In this embodiment, if Figure 1 As shown, the bearing processing method includes steps S10 to S40, and steps S10 to S40 are described in detail below:

[0044] In step S10, the inner ring unit 22 is cut along the axial direction at the abutment ring 223 to obtain the inner ring detection ring 30. In this way, the inner ring detection ring 30 can be separated from the inner ring unit 22 for subsequent testing and experiments, providing a basis for determining appropriate processing parameters.

[0045] In step S20, a first backing ring 40 is obtained based on the inner ring inspection ring 30. The first backing ring 40 and the inner ring inspection ring 30 are made of the same material to ensure the validity of the experimental data. Here, H0+H1<H, where H0 is the height of the inner ring inspection ring 30, H1 is the height of the first backing ring 40, and H is the height of the inner ring unit 22. The first backing ring 40 ensures that the sum of the heights of the inner ring inspection ring 30 and the first backing ring 40 is less than the height of the inner ring unit 22. This combination of the first backing ring 40 and the inner ring inspection ring 30 simulates the stresses on the inner ring unit 22 during the hemming process, allowing for the acquisition of appropriate processing parameters, thereby ensuring better control over the locking effect between the inner ring unit 22 and the flange unit 21 during actual production.

[0046] In step S30, after the first backing ring 40 and the inner ring detection ring 30 are sequentially mounted on the flange unit 21, the press-fitting unit 12 compresses and crimps the crimping ring 214. Simultaneously, the detection unit detects the locking force of the first backing ring 40, ensuring that the locking force of the first backing ring 40 reaches the set locking force and obtaining the first crimping force F1. This allows the appropriate magnitude of the first crimping force F1 to be determined experimentally by utilizing the change in the locking force of the first backing ring 40 during the crimping process, providing accurate parameters for the subsequent crimping of the inner ring unit 22 and the flange unit 21.

[0047] In step S40, based on F1, the inner ring unit 22 and the flange unit 21 are crimped with a set crimping force F0. Where F0 ≥ F1, the crimping of the inner ring unit 22 and the flange unit 21 with a larger set crimping force F0 results in a tighter crimping and a more secure connection between the inner ring unit 22 and the flange unit 21, thereby ensuring the secureness and stability of the connection between the inner ring unit 22 and the flange unit 21.

[0048] Furthermore, H0+H1≥0.95×H. Here, H0 is the height of the inner ring inspection ring 30, H1 is the height of the first backing ring 40, and H is the height of the inner ring unit 22. This limits the combined height of the first backing ring 40 and the inner ring inspection ring 30, ensuring that it is within an appropriate range and avoiding the situation where H0+H1 is less than 0.95×H. If the height is too small, the first crimping force F1 obtained during the subsequent crimping process will be too large. Excessive first crimping force F1 can easily cause excessive deformation of the second raceway portion 222, thereby increasing the rolling resistance of the bearing and affecting the normal performance and service life of the bearing.

[0049] Furthermore, when the first washer 40 is mounted on the flange unit 21, the inner ring of the first washer 40 is spaced apart from the outer ring of the abutment column 213 on the flange unit 21. During the curling process, the abutment column 213 is subjected to pressure from the curling ring 214 and deforms radially toward the first washer 40. If the first washer 40 and the abutment column 213 are not spaced apart, the first washer 40 will deform radially, resulting in an excessively large first curling force F1, ultimately causing the second raceway portion 222 to deform, affecting the normal operating performance of the bearing. Therefore, by spacing the first washer 40 and the flange unit 21 apart, a certain amount of space can be reserved between the two, preventing the first washer 40 from fitting tightly against the flange unit 21. This allows for better control of the curling process, obtaining a more appropriate first curling force F1, and effectively preventing excessive deformation of the second raceway portion 222 during actual production, thereby ensuring stable bearing performance.

[0050] Furthermore, the cutaway ring, cut along the axis of the abutment ring 223 of the inner ring unit 22, is annular. Here, D0 = D1, where D0 is the outer diameter of the cutaway ring and D1 is the outer diameter of the first backing ring 40. This ensures dimensional consistency between the cutaway ring and the first backing ring 40, enabling more accurate simulation of the forces acting on the inner ring unit 22. This results in a more accurate first hemming force F1, providing a more reliable parameter basis for the subsequent hemming process of the inner ring unit 22 and the flange unit 21.

[0051] Furthermore, d0<d1≤1.05×d0. Among them, d0 is the inner diameter of the cutting ring, and d1 is the inner diameter of the first gasket 40. Through the relationship between the inner diameters of the cutting ring and the first gasket 40, the first gasket 40 and the flange unit 21 are spaced apart, and a certain space can be reserved between the two. In this way, the curling process can be better controlled, and a more appropriate first curling force F1 can be obtained, thereby ensuring the stable performance of the bearing. Avoid the first gasket 40 and the flange unit 21 from fitting tightly, causing the first gasket 40 to be affected by the tensioning force of the curling ring 214, resulting in inaccurate first curling force F1.

[0052] In other embodiments, the bearing processing method further includes steps S50 to S70. The bearing processing method sequentially performs steps S10, S20, S30, S50, S60, and S70. Steps S50 to S70 are described in detail below:

[0053] In step S50, a second gasket 50 is obtained based on the inner ring inspection ring 30. The second gasket 50 is made of the same material as the inner ring inspection ring 30, thereby ensuring the validity of the experimental data. Here, H0+H2>H, where H0 is the height of the inner ring inspection ring 30, H2 is the height of the second gasket 50, and H is the height of the inner ring unit 22. The second gasket 50 ensures that the sum of the heights of the inner ring inspection ring 30 and the second gasket 50 is greater than the height of the inner ring unit 22. This combination of the second gasket 50 and the inner ring inspection ring 30 simulates the stresses on the inner ring unit 22 during the hemming process, allowing for the acquisition of appropriate processing parameters, thereby ensuring better control over the locking effect between the inner ring unit 22 and the flange unit 21 during actual production.

[0054] In step S60, after the second backing ring 50 and the other inner inspection ring 30 are sequentially mounted on the flange unit 21, the press-fitting unit 12 compresses and crimps the crimping ring 214. Simultaneously, the detection unit tests the locking force of the first backing ring 40, ensuring that the tension of the inner inspection ring 30 reaches a set tension force to obtain a second crimping force F2. The set tension force is the damage threshold for the inner inspection ring 30. Through this experimental method, the magnitude of the second crimping force F2 is determined by utilizing the changes in the locking force of the second backing ring 50 during the crimping process, thereby obtaining crimping force data under different stress conditions.

[0055] Step S70 is a further optimization of step S40. In step S70, based on the condition F2>F1, the inner ring unit 22 and the flange unit 21 are crimped with a set crimping force F0. Here, F2>F0≥F1. Using the first and second washers 40, 50 of different heights, the first and second crimping forces F1, F2 are obtained, and the appropriate set crimping force F0 is determined to crimp the inner ring unit 22 and the flange unit 21. The final set crimping force F0 thus adopted satisfies the locking requirements of the connection while preventing cracks from excessive deformation of the inner ring unit 22 due to excessive crimping force. This effectively prevents quality issues with the inner ring unit 22 due to excessive deformation, thereby ensuring the overall quality and reliability of the wheel hub bearing.

[0056] Furthermore, H0+H2≤1.05×H, where H2 is the height of the second backing ring 50, H0 is the height of the inner ring detection ring 30, and H is the height of the inner ring unit 22. This limits the combined height of the second backing ring 50 and the inner ring detection ring 30, ensuring that they remain within an appropriate range and preventing the sum of the inner ring detection ring 30 height H0 and the second backing ring 50 height H2 from being excessive. Excessive heights can result in excessively large second crimping force F2 during the subsequent crimping process. Excessive second crimping force F2 can easily cause excessive deformation of the second raceway portion 222, leading to cracks. This can increase the bearing's rolling resistance and affect its performance and service life.

[0057] Furthermore, the bearing processing method further includes step S80. The bearing processing method sequentially performs step S10, step S20, step S30, step S50, step S60, step S70, and step S80. Step S80 is described in detail below:

[0058] Step S80, based on F2≤F1, issues abnormal signals for the first curling force F1 and the second curling force F2. This allows for timely early warning of test data that does not meet expectations during the curling force test. Under normal circumstances, the second curling force F2 should be greater than the first curling force F1. If F2≤F1 occurs, it means that there are operational errors, measurement errors, and abnormalities during the experiment. Therefore, issuing prompts for abnormalities in the first curling force F1 and the second curling force F2 in a timely manner helps technicians quickly detect abnormalities in the experimental data, thereby checking and correcting the experimental process, avoiding subsequent curling processing operations based on erroneous data, and ensuring the accuracy and reliability of the wheel hub bearing curling processing parameters.

[0059] Example 2:

[0060] In this embodiment, if Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the bearing processing system can be applied to a bearing processing method. The bearing processing system can include a press-fit assembly 10, an inner ring detection ring 30, a first backing ring 40, a detection assembly, and a cutting assembly.

[0061] The press-fitting assembly 10 includes a support unit 11, a press-fitting unit 12, and a drive unit 13. The inner race inspection ring 30 can be placed on the side of the support unit 11 facing the press-fitting unit 12. The support unit 11 is arranged horizontally to facilitate the subsequent placement and processing of the inner race inspection ring 30. The press-fitting unit 12 includes a connecting post 121, a positioning post 122, a curling groove 123, and a stopper 124. One end of the connecting post 121 is connected to the drive unit 13, and the other end is connected to the positioning post 122. The drive unit 13 can drive the connecting post 121 to move. The stopper 124 and the positioning post 122 form a curling groove 123; the curling groove 123 is used to curl the inner race inspection ring 30. The stopper 124 and the curling groove 123 limit and guide the inner race inspection ring 30 during the curling process, ensuring the shape and size of the curling, and making the curling operation more standardized and accurate.

[0062] The inner ring assembly 20 includes a flange unit 21 and an inner ring unit 22. The flange unit 21 includes a flange 211, a first raceway 212, abutment posts 213, and a crimping ring 214. The flange 211, first raceway 212, abutment posts 213, and crimping ring 214 are connected in sequence along the axial direction of the flange 211. When the flange unit 21 is placed on the support unit 11, the flange 211 abuts the support unit 11, leveraging the support provided by the support unit 11 to facilitate bearing machining. The crimping ring 214 extends away from the flange 211. The inner ring unit 22 includes a support ring 221, a second raceway 222, and abutment ring 223. The support ring 221, second raceway 222, and abutment ring 223 are connected in sequence along the axial direction of the support ring 221. During the crimping operation, support ring 221 abuts against stopper 124, and abutment ring 223 connects to abutment post 213, ensuring that support ring 221, second raceway 222, and abutment ring 223 are stably mounted on flange unit 21. The first and second raceways are used to hold balls, ensuring smoother bearing rotation and reducing energy consumption during use. The cutting assembly is used to sever the abutment ring 223 of inner ring unit 22 along the axis, resulting in a circular ring.

[0063] The abutment ring 223 of the inner ring unit 22 is cut along the axial direction to obtain the inner ring detection ring 30 for testing the bearing processing method, thereby obtaining appropriate parameters and providing an important basis for subsequent actual production.

[0064] After the cutting assembly cuts the inner ring unit 22 axially at the abutment ring 223, the first gasket 40 is obtained from the cutaway ring. This cutaway ring provides a reference for subsequent fabrication of the first gasket 40 and for hemming experiments. To ensure the authenticity of the experimental data, the cutaway ring and the first gasket 40 are made of the same material. H0+H1<H. Here, H0 is the height of the inner ring inspection ring 30, H1 is the height of the first gasket 40, and H is the height of the inner ring unit 22. The first gasket 40 ensures that the sum of the heights of the inner ring inspection ring 30 and the first gasket 40 is less than the height of the inner ring unit 22. This combination of the first gasket 40 and the inner ring inspection ring 30 simulates the stresses on the inner ring unit 22 during hemming, enabling the identification of appropriate processing parameters and ensuring better control of the locking effect between the inner ring unit 22 and the flange unit 21 during actual production.

[0065] The detection assembly includes a detector, a first detection head, and a second detection head. The first and second detection heads are electrically connected to the detector. The first detection head measures the locking force applied to the inner detection ring 30, while the second detection head measures the tension applied to the first backing ring 40. The detector acquires data collected by the first and second detection heads, providing a basis for analyzing and determining relevant parameters during the hemming process.

[0066] The bearing processing system includes an assembly state, and the assembly state includes the driving unit 13 driving the connecting part so that the support ring 221, the second raceway part 222 and the abutment ring 223 are sleeved on the outer peripheral wall of the abutment column 213, so that the curling ring 214 is located in the curling groove 123, the support ring 221 abuts against the limiting part 124, and then the curling is extruded, so that the inner ring unit 22 is stably connected to the flange unit 21.

[0067] Furthermore, the bearing processing system also includes a second backing ring 50. After the cutting assembly cuts the inner ring unit 22 along the axis at the abutment ring 223, the second backing ring 50 is removed by cutting the ring. H0+H2>H, where H2 is the height of the second backing ring 50, H0 is the height of the inner ring inspection ring 30, and H is the height of the inner ring unit 22. This height difference between the first backing ring 40 and the second backing ring 50 can be used to simulate different stress conditions and structural states during the crimping test. By comparing experimental data from the first and second backing rings 40, 50, such as crimping force, locking force, and tension force, a more comprehensive understanding of the impact of different height settings on the crimping process can be achieved, providing data support for determining an appropriate crimping force F0. This set crimping force F0 meets the locking requirements of the connection while preventing excessive deformation of the inner ring unit 22 that could cause cracks. This effectively prevents quality issues with the inner ring unit 22 due to excessive deformation, thereby ensuring the overall quality and reliability of the wheel hub bearing.

[0068] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
