Description

Technical Field

[0001] This invention relates to the field of bearing technology, and more specifically, to a bearing processing method and system. Background Technology

[0002] In the machining process of wheel hub inner ring bearings, the inner ring and flange are connected by an interference fit, but the connection reliability is relatively low. Therefore, a crimping process is used to further connect the flange and inner ring. This process changes the shape and position of the flange by crimping the upper part of the flange, allowing the flange and inner ring to fit tightly together and form a robust connection structure. This meets the functional requirements of the wheel hub inner ring bearing in subsequent use, such as bearing loads and transmitting torque, thereby ensuring the normal operation and product quality of the wheel hub inner ring bearing.

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

[0004] To address the problem of insufficient inner ring locking force during the machining of wheel hub inner ring bearings, this invention provides a bearing machining method and system.

[0013] In some embodiments, d0 < d1 ≤ 1.05 × d0; where d0 is the inner diameter of the cut-off ring and d1 is the inner diameter of the first pad ring.

[0014] In some embodiments, a second pad ring is obtained based on the inner ring detection ring; wherein, H0+H2>H, H0 is the height of the inner ring detection ring, H2 is the height of the second pad ring, and H is the height of the inner ring unit;

[0015] Based on the second gasket and the other inner ring detection ring being sequentially fitted onto the flange unit, the inner ring detection ring is squeezed and rolled so that the tension force of the inner ring detection ring reaches the set tension force, and the second rolling force F2 is obtained.

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

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

[0018] In some embodiments, based on F2≤F1, a first curling force F1 and a second curling force F2 are generated.

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

[0020] A press-fitting assembly includes a support unit, a press-fitting unit, and a drive unit; the press-fitting unit includes a connecting post, a positioning post, a crimping groove, and a limiting part; 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 part and the positioning post form the crimping groove;

[0021] An inner ring assembly includes a flange unit and an inner ring unit; the flange unit includes a flange, a first raceway portion, an abutment post, and a rolled edge ring; the flange, the first raceway portion, the abutment post, and the rolled edge ring are sequentially connected along the axial direction of the flange; the rolled edge ring extends in a direction away from the flange; the inner ring unit includes a support ring, a second raceway portion, and an abutment ring; the support ring, the second raceway portion, and the abutment ring are sequentially connected along the axial direction of the support ring;

[0022] A cutting assembly is used to cut off the abutment ring of the inner ring unit along the axial direction, and the cut-off ring is circular.

[0023] Inner ring detection ring: The inner ring unit is cut along the axial direction at the abutment ring to obtain the inner ring detection ring;

[0024] The first washer ring is obtained by cutting off the abutment ring of the inner ring unit along the axial direction by the cutting component; H0+H1<H; where H0 is the height of the inner ring detection ring, H1 is the height of the first washer ring, and H is the height of the inner ring unit;

[0025] The detection assembly includes a detector, a first detection head, and a second detection head; the first detection head and the second detection head are respectively electrically connected to the detector.

[0026] The bearing processing system includes an assembly state, in which the drive unit drives the connecting part so that the support ring, the second raceway part and the abutment ring are sleeved on the outer peripheral wall of the abutment post.

[0027] In some embodiments, the bearing processing system further includes a second washer; after the cutting assembly cuts off the abutment ring of the inner ring unit along the axial direction, the second washer is obtained through the cutting ring; H0+H2>H; where H2 is the height of the second washer.

[0028] To solve the problem of insufficient inner ring locking force during the machining process of wheel hub inner ring bearings, this invention has the following advantages:

[0029] The inner ring detection ring is obtained by cutting off the abutment ring of the inner ring unit along the axial direction. The first washer ring and the inner ring detection ring are then sequentially fitted onto the flange unit for compression and crimping. The sum of the height H0 of the inner ring detection ring and the height H1 of the first washer ring is less than the height H of the inner ring unit. During the compression and crimping process, the axial pressure, i.e., the locking force, is calculated by measuring the circumferential deformation of the first washer ring. When the locking force reaches the set locking force, the first crimping force F1 is obtained. Based on F1, the inner ring unit and the flange unit are crimped with a set crimping force F0 greater than the first crimping force F1. This allows for precise measurement of the appropriate crimping force, effectively controlling the locking force during the crimping process of the inner ring unit and the flange unit, thus avoiding insufficient inner ring locking force due to inappropriate crimping force. Ultimately, this results in a more secure connection between the inner ring unit and the flange unit, improving the machining quality and connection stability of the wheel hub bearing.

[0039] During the machining of wheel hub bearings, a crimping process is required to connect the flange unit 21 and the inner ring unit 22 into one unit. However, it is crucial to properly determine the crimping process parameters before performing the crimping operation. If the crimping process parameters are not selected properly, insufficient locking force of the inner ring unit 22 may occur during the crimping process, resulting in an insecure connection and affecting the normal performance of the wheel hub bearing; conversely, excessive tightening force of the inner ring unit 22 may occur, causing excessive deformation of the inner ring unit 22, resulting in loosening of the balls inside the inner ring, thereby affecting the overall quality and reliability of the wheel hub bearing.

[0040] Example 1:

[0041] To address the aforementioned problems, this embodiment provides a bearing processing method. The bearing processing system involved in this embodiment includes a press-fit assembly 10, an inner ring inspection ring 30, a first washer ring 40, an inspection assembly, and a cutting assembly.

[0042] The pressing assembly 10 includes a support unit 11, a pressing 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 can drive the inner ring unit 22 to connect with the flange unit 21. The drive unit 13 drives the pressing unit 12 to press and curl the inner ring unit 22 and the flange unit 21. During the curling operation, the support unit 11 provides stable support for the bearing processing. After the cutting assembly cuts the abutment ring 223 of the inner ring unit 22 along the axial direction, the first gasket 40 is obtained through the cut ring. The cut ring provides a reference basis for the subsequent fabrication of the first gasket 40 and the curling experiment. The detector is used to acquire data collected by the first and second detection heads, providing a basis for analyzing and judging relevant parameters during the curling process.

[0043] In this embodiment, as Figure 1 As shown, the bearing processing method includes steps S10 to S40, which will be described in detail below:

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

[0045] Step S20: Based on the inner ring detection ring 30, a first gasket ring 40 is obtained. The first gasket ring 40 is made of the same material as the inner ring detection ring 30, thus ensuring the validity of the experimental data. Where H0 + H1 < H, H0 is the height of the inner ring detection ring 30, H1 is the height of the first gasket ring 40, and H is the height of the inner ring unit 22. The first gasket ring 40 ensures that the sum of the heights of the inner ring detection ring 30 and the first gasket ring 40 is less than the height of the inner ring unit 22. This combination of the first gasket ring 40 and the inner ring detection ring 30 can simulate the stress on the inner ring unit 22 during the crimping process, obtaining suitable processing parameters, thereby ensuring better control of the locking effect between the inner ring unit 22 and the flange unit 21 in actual production.

[0046] In step S30, based on the first washer ring 40 and the inner ring detection ring 30 being sequentially fitted onto the flange unit 21, the pressing unit 12 presses and curls the edge of the crimping ring 214. Simultaneously, the detection unit detects the locking force of the first washer ring 40, ensuring it reaches the set locking force, and obtains the first crimping force F1. This allows for the experimental determination of the appropriate first crimping force F1 by utilizing the change in the locking force of the first washer 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] Step S40: Based on F1, perform edge curling on the inner ring unit 22 and the flange unit 21 with a set edge curling force F0. Where F0 ≥ F1. Performing edge curling on the inner ring unit 22 and the flange unit 21 with a larger set edge curling force F0 makes the edge curling of the inner ring unit 22 and the flange unit 21 tighter, resulting in a more secure connection, thereby ensuring the strength 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 detection ring 30, H1 is the height of the first washer ring 40, and H is the height of the inner ring unit 22. This limits the sum of the heights of the first washer ring 40 and the inner ring detection ring 30, ensuring it is within a suitable range and avoiding H0 + H1 < 0.95 × H. If the height is too small, the first crimping force F1 obtained during the subsequent crimping process will be too large. An excessively large first crimping force F1 can easily lead to excessive deformation of the second raceway 222, thereby increasing the rolling resistance of the bearing and affecting its normal performance and service life.

[0049] Furthermore, when the first washer 40 is fitted onto the flange unit 21, the inner ring of the first washer 40 is spaced apart from the outer ring of the abutment post 213 on the flange unit 21. This is because during the crimping process, the abutment post 213 is subjected to pressure from the crimping ring 214, causing it to deform radially toward the first washer 40. If the first washer 40 and the abutment post 213 are not spaced apart, the first washer 40 will deform radially, resulting in an excessively large first crimping force F1. This would ultimately cause deformation of the second raceway portion 222, affecting the normal operating performance of the bearing. Therefore, by spaced the first washer 40 and the flange unit 21, a certain space is reserved between them, preventing the first washer 40 from being tightly fitted to the flange unit 21. This allows for better control of the crimping process, obtaining a more suitable first crimping force F1, effectively preventing excessive deformation of the second raceway portion 222 during actual production, thereby ensuring the stable performance of the bearing.

[0050] Furthermore, the cut-off ring at the abutment ring 223 of the inner ring unit 22, after being cut along the axial direction, is annular. Here, D0 = D1, where D0 is the outer diameter of the cut-off ring and D1 is the outer diameter of the first washer ring 40. This ensures that the cut-off ring and the first washer ring 40 are consistent in size, thus enabling a more accurate simulation of the stress conditions on the inner ring unit 22. This makes the obtained first crimping force F1 more accurate, providing a more reliable parameter basis for the subsequent crimping processing of the inner ring unit 22 and the flange unit 21.

[0051] Furthermore, d0 < d1 ≤ 1.05 × d0. Where d0 is the inner diameter of the cut-off ring, and d1 is the inner diameter of the first washer ring 40. By controlling the relationship between the inner diameters of the cut-off ring and the first washer ring 40, the first washer ring 40 and the flange unit 21 are spaced apart, allowing for a certain amount of space between them. This enables better control of the crimping process, obtaining a more suitable first crimping force F1, thereby ensuring stable bearing performance. It also prevents the first washer ring 40 from being tightly fitted to the flange unit 21, which could cause the first washer ring 40 to be affected by the tension force of the crimping ring 214, resulting in an inaccurate first crimping force F1.

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

[0053] Step S50: Based on the inner ring detection ring 30, a second washer ring 50 is obtained. The second washer ring 50 is made of the same material as the inner ring detection ring 30, thus ensuring the validity of the experimental data. Wherein, H0 + H2 > H, H0 is the height of the inner ring detection ring 30, H2 is the height of the second washer ring 50, and H is the height of the inner ring unit 22. The second washer ring 50 ensures that the sum of the heights of the inner ring detection ring 30 and the second washer ring 50 is greater than the height of the inner ring unit 22. This combination of the second washer ring 50 and the inner ring detection ring 30 can simulate the stress on the inner ring unit 22 during the crimping process, obtaining suitable processing parameters, thereby ensuring better control of the locking effect between the inner ring unit 22 and the flange unit 21 in actual production.

[0054] In step S60, the second washer ring 50 and another inner ring detection ring 30 are sequentially fitted onto the flange unit 21. The pressing unit 12 presses and curls the crimped ring 214. Simultaneously, the detection unit detects the locking force of the first washer ring 40, ensuring that the tension of the inner ring detection ring 30 reaches the set tension, and obtaining the second crimping force F2. The tension is set as the damage threshold for the inner ring detection ring 30. Through this experimental method, the magnitude of the second crimping force F2 is obtained by utilizing the change in the locking force of the second washer ring 50 during the crimping process, thereby obtaining data on the crimping force under different stress conditions.

[0055] Step S70 is a further optimization of step S40. In step S70, based on F2 > F1, the inner ring unit 22 and the flange unit 21 are crimped with a set crimping force F0. Where F2 > F0 ≥ F1. The first crimping force F1 and the second crimping force F2 are obtained using the first washer 40 and the second washer 50 at different heights, and a suitable set crimping force F0 is determined for crimping the inner ring unit 22 and the flange unit 21. Therefore, the final set crimping force F0 satisfies the locking requirements of the connection without causing excessive deformation of the inner ring unit 22 due to excessive crimping force, thus effectively preventing quality problems caused by excessive deformation of the inner ring unit 22, and 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 washer 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 sum of the heights of the second washer ring 50 and the inner ring detection ring 30, ensuring it is within a suitable range and preventing the sum of the heights H0 and H2 of the inner ring detection ring 30 from being too large. If the height is too large, the second crimping force F2 obtained during the subsequent crimping process will be too large. An excessively large second crimping force F2 can easily lead to excessive deformation of the second raceway 222, resulting in cracks, thereby increasing the rolling resistance of the bearing and affecting its normal performance and service life.

[0057] Furthermore, the bearing processing method also includes step S80. The bearing processing method sequentially executes steps S10, S20, S30, S50, S60, S70, and S80. Step S80 will be described in detail below:

[0058] Step S80: Based on F2≤F1, issue abnormal signals for the first and second edge-rolling forces F1 and F2. This allows for timely warnings of unexpected test data during the edge-rolling force test. Under normal circumstances, the second edge-rolling force F2 should be greater than the first edge-rolling force F1. If F2≤F1, it indicates operational errors, measurement errors, or other abnormalities during the experiment. Therefore, timely issuance of abnormal signals for the first and second edge-rolling forces F1 and F2 helps technicians quickly detect abnormalities in the experimental data, thereby allowing for inspection and correction of the experimental process. This avoids subsequent edge-rolling operations based on erroneous data, ensuring the accuracy and reliability of the wheel hub bearing edge-rolling process parameters.

[0059] Example 2:

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

[0061] The pressing assembly 10 includes a support unit 11, a pressing unit 12, and a drive unit 13. The inner ring detection ring 30 can be placed on the side of the support unit 11 facing the pressing unit 12. The support unit 11 is horizontally positioned to facilitate the subsequent placement and processing of the inner ring detection ring 30. The pressing unit 12 includes a connecting post 121, a positioning post 122, a crimping groove 123, and a limiting part 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 limiting part 124 and the positioning post 122 form the crimping groove 123; the crimping groove 123 is used to crimp the inner ring detection ring 30. The limiting part 124 and the crimping groove 123 can limit and guide the inner ring detection ring 30 during the crimping process, ensuring the shape and size of the crimp, and making the crimping 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 portion 212, an abutment post 213, and a rolled edge ring 214. The flange 211, first raceway portion 212, abutment post 213, and rolled edge ring 214 are sequentially connected along the axial direction of the flange 211. When the flange unit 21 is placed on the support unit 11, the flange 211 abuts against the support unit 11, utilizing the supporting effect of the support unit 11 to facilitate bearing machining. The rolled edge ring 214 extends away from the flange 211. The inner ring unit 22 includes a support ring 221, a second raceway portion 222, and an abutment ring 223. The support ring 221, second raceway portion 222, and abutment ring 223 are sequentially connected along the axial direction of the support ring 221. During the crimping operation, the support ring 221 abuts against the limiting part 124, and the abutment ring 223 connects to the abutment post 213, ensuring that the support ring 221, the second raceway part 222, and the abutment ring 223 can be stably installed on the flange unit 21. The first and second raceways are used to hold the balls, thereby making the bearing rotate more smoothly during use and reducing energy consumption. The cutting assembly is used to cut off the abutment ring 223 of the inner ring unit 22 along the axial direction, and the cut-off ring is circular.

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

[0064] After the cutting assembly cuts off the abutment ring 223 of the inner ring unit 22 along the axial direction, the first washer ring 40 is obtained through the cutting ring. The cut ring provides a reference basis for the subsequent fabrication of the first washer ring 40 and the edge-rolling experiment. To ensure the authenticity of the experimental data, the cutting ring and the first washer ring 40 are made of the same material. H0 + H1 < H. Where H0 is the height of the inner ring detection ring 30, H1 is the height of the first washer ring 40, and H is the height of the inner ring unit 22. The first washer ring 40 is used to ensure that the sum of the heights of the inner ring detection ring 30 and the first washer ring 40 is less than the height of the inner ring unit 22. In this way, the combination of the first washer ring 40 and the inner ring detection ring 30 can simulate the stress situation of the inner ring unit 22 during the edge-rolling process, obtain appropriate processing parameters, and thus ensure better control of the locking effect between the inner ring unit 22 and the flange unit 21 in the actual production process.

[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 can collect the locking force on the inner detection ring 30, and the second detection head can collect the tension force on the first washer ring 40. The detector is used to acquire the data collected by the first and second detection heads, providing a basis for analyzing and judging relevant parameters during the crimping process.

[0066] The bearing processing system includes an assembly state, in which the drive unit 13 drives 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 post 213, so that the crimping ring 214 is located in the crimping groove 123, the support ring 221 abuts against the limiting part 124, and then the crimping is performed to make the inner ring unit 22 and the flange unit 21 stably connected.

[0067] Furthermore, the bearing processing system also includes a second washer 50. After the cutting assembly cuts off the abutment ring 223 of the inner ring unit 22 along the axial direction, the second washer 50 is obtained through the cutting ring. H0 + H2 > H, where H2 is the height of the second washer 50, H0 is the height of the inner ring detection ring 30, and H is the height of the inner ring unit 22. In this way, by utilizing the height difference between the first washer 40 and the second washer 50, different stress conditions and structural states can be simulated during the crimping experiment. By comparing the experimental data when using the first washer 40 and the second washer 50, such as crimping force, locking force, and tensioning force, a more comprehensive understanding of the impact of different height settings on the crimping process can be obtained, thus providing data support for obtaining a suitable set crimping force F0. The set crimping force F0 adopted can meet the locking requirements of the connection without causing excessive deformation of the inner ring unit 22 due to excessive crimping force, thereby effectively avoiding quality problems caused by excessive deformation of the inner ring unit 22, and thus ensuring the overall quality and reliability of the wheel hub bearing.

[0068] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
