Description

Technical Field

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

[0002] In the current bearing assembly technology, for seals, in addition to manual installation, mechanical press-fitting is widely used. The seal can prevent the lubricant leakage inside the bearing assembly and the intrusion of external impurities, thereby ensuring the normal operation of the bearing and extending its service life. The common press-fitting method is to fix one of the bearing or the seal and apply pressure to the other one that has been positioned to ensure that the seal unit can fit tightly to the inner and outer rings of the bearing after installation to achieve an effective sealing effect.

[0003] However, existing bearing assemblies face a significant technical problem when installing sealing rings. Since the bearing assembly is divided into an inner ring and an outer ring, with rollers arranged therebetween, there will be a certain amount of play between these rollers and the outer circumferential wall of the inner ring and the inner circumferential wall of the outer ring to facilitate the smooth rotation of the rollers. However, when the sealing ring is press-fitted, if sufficient pressure is directly applied, part of the play will be eliminated while the sealing ring is installed. Under top-down pressure, the play cannot be pressed evenly, which may cause the rollers to be inaccurately positioned and stuck. Roller jamming will not only impair the normal operation of the bearing assembly, but may also cause serious mechanical failures. Therefore, how to ensure the correct installation of the sealing ring while preventing the rollers from being stuck due to excessive pressure has become a key issue that needs to be urgently addressed in the current bearing assembly technology. Summary of the invention

[0033] A press-fitting assembly, the press-fitting assembly comprises a press head unit and a press-fitting seat unit; the press-fitting seat unit comprises a bottom die, an elastic module and a guide module; the bottom die comprises a mounting seat and a mounting groove, the mounting groove is arranged on the upper surface of the mounting seat; the guide module comprises a guide part and a support part; the support part is movably connected to the mounting seat; the guide part is fixedly connected to the support part; one end of the elastic module is detachably connected to the mounting seat, and the other end is detachably connected to the support part; the end of the elastic module detachably connected to the support part is located inside the support part;

[0034] A bearing assembly, the bearing assembly comprising an outer ring unit, a roller, an inner ring unit, a sealing unit and a retaining frame; the inner ring unit comprises a first inner ring and a second inner ring, the first inner ring and the second inner ring are arranged along an axis; the outer ring unit is sleeved outside the inner ring unit; the rollers are detachably connected to the retaining frame; at least a part of the rollers is arranged between the first inner ring and the outer ring unit, and another part is arranged between the second inner ring and the outer ring unit; the rollers are slidably connected to the outer ring unit, and the rollers are slidably connected to the inner ring unit;

[0035] The bearing assembly mounting system includes a press-fit state and the press-fit state;

[0036] The press-fit state includes the inner ring unit being sleeved on the guide portion, and the sealing unit being arranged in the mounting groove;

[0041] According to the bearing assembly seal ring press-fitting method of the present invention, the pressure head unit is first driven to move to abut against the first inner ring, and then the pressure head unit is driven to move to a press-fit state, so that the sealing unit is installed. By utilizing the structural characteristics that the inner ring of the bearing is divided into two parts, the upper and lower parts are first pressed with a smaller force and a slower speed before the seal ring is pressed. In this process, since the pressing force is less than the spring elastic force, the spring will not be compressed, and the clearance around the roller will be eliminated before the upper and lower gaps of the inner ring are completely eliminated. Then, after the upper and lower parts of the inner ring of the bearing are completely pressed, the pressing force is increased to compress the spring, so that the seal ring is smoothly pressed into the bearing assembly. In this way, the effect of graded pressing is achieved during the installation of the seal ring, and the problem of roller jamming caused by directly applying excessive pressure is effectively avoided. Finally, not only the accurate installation of the seal ring is guaranteed, but also the normal operation of the bearing assembly is ensured, and the reliability and service life of the bearing assembly are improved.

[0048] The bearing is composed of a bearing outer ring, a bearing inner ring, a roller 22, a sealing ring and a retaining frame 25. Common methods for installing sealing rings include manual installation and mechanical pressing. Mechanical pressing generally fixes one of the bearing or the sealing ring, and then applies pressure to the other to press the two together. Among them, mechanical pressing with higher installation efficiency faces a problem. There is a clearance between the roller 22 between the inner ring and the outer ring of the bearing and the outer circumferential wall of the inner ring and the inner circumferential wall of the outer ring. Appropriate clearance can effectively improve the bearing capacity of the bearing. However, when the sealing ring of the bearing is pressed, before the sealing ring is pressed, the clearance between the roller 22 and the inner and outer rings of the bearing will also be pressed. Under the pressure from top to bottom, the clearance cannot be pressed evenly, which may cause the roller 22 to be inaccurately positioned and stuck.

[0049] To solve this problem, this embodiment discloses a method for installing a bearing assembly 02, such as Figure 1 As shown, it may include step S10 to step S30, and each step is described in detail as follows:

[0050] In step S10, the inner ring unit 23 of the bearing assembly 02 can be precisely positioned by the guide module 123, and then the press head unit 11 can be driven to move toward the inner ring unit 23. This step can ensure that the inner ring unit 23 is accurately placed on the guide module 123, providing a basis for the subsequent press-fitting process, thereby achieving the effect of improving the press-fitting accuracy.

[0051] Step S20, after the moving pressure head unit 11 abuts against the first inner ring 231 of the inner ring unit 23, the pressure head unit 11 can drive the first inner ring 231 to move toward the second inner ring 232. The inner ring unit 23 includes the first inner ring 231 and the second inner ring 232, and the second inner ring 232 is arranged on the side of the first inner ring 231 away from the pressure head unit 11. In the process of the first inner ring 231 moving toward the second inner ring 232, the interval between the first inner ring 231 and the second inner ring 232, the clearance between the roller 22 and the inner ring unit 23, and the clearance between the roller 22 and the outer ring unit 21 are all reduced as the first inner ring 231 moves.

[0052] Step S30, when the first inner ring 231 abuts against the second inner ring 232 under the pressure of the pressure head unit 11, the interval between the first inner ring 231 and the second inner ring 232, the clearance between the roller 22 and the inner ring unit 23, and the clearance between the roller 22 and the outer ring unit 21 are all eliminated, and the pressure head unit 11 can be driven to move toward the inner ring unit 23 to a pressing state. The pressing state can include the installation space where the sealing unit 24 is located between the outer ring unit 21 and the inner ring unit 23, that is, the sealing unit 24 is accurately pressed to the specified position, and the roller 22 will not be stuck because the clearance is eliminated in advance, thereby solving the problem that the roller 22 is easy to be stuck when the sealing unit 24 is installed.

[0053] In this embodiment, in step S30, the abutment between the first inner ring 231 and the second inner ring 232 includes that when the first inner ring 231 is subjected to the pressure Fb of the pressure head unit 11, the second inner ring 232 is subjected to the reaction force of the elastic module 122, Fa>Fb. Wherein, Fa is the elastic force of the elastic module 122 set to the compression stroke. The press-fitting seat unit 12 includes an elastic module 122, one end of which is detachably connected to the mounting seat 1212, and the other end is detachably connected to the guide module 123. Through this structure, the press-fitting process can be buffered, and the pressure head unit 11 is prevented from directly applying a pressure greater than the set compression stroke of the elastic module 122 to the inner ring unit 23, thereby eliminating the clearance before the elastic module 122 is compressed, that is, before the sealing unit 24 is installed, and finally solving the problem of the roller 22 being stuck during the press-fitting process.

[0054] In this embodiment, step S20 includes step S21 to step S26, and each step is described in detail as follows:

[0055] Step S21, after driving the pressure head unit 11 to move toward the inner ring unit 23, obtain the first pressure value F1. The first pressure value F1 is the pressure exerted by the pressure head unit 11 on the inner ring unit 23. Through this step, the pressure exerted by the pressure head unit 11 on the inner ring unit 23 can be monitored in real time, providing a basis for subsequent processes.

[0056] Step S22, when the first pressure value F1 is greater than the preset pressure value Fc and less than the elastic force Fa of the compression stroke set by the elastic module 122, the first height H1 of the pressing head unit 11 is obtained. Through this step, it can be determined whether the pressing head unit 11 is just in contact with the first inner ring 231, providing a reference point for the subsequent press-fitting process.

[0057] Step S23 , after obtaining the first height H1 , the pressing head unit 11 may be driven to continue moving toward the pressing seat unit 12 .

[0058] Step S24, after the pressure head unit 11 moves toward the press-fitting seat unit 12, a second pressure value F2 is obtained. The second pressure value F2 is the pressure of the pressure head unit 11 on the inner ring unit 23. Through this step, the position and pressure of the pressure head unit 1111 can be further adjusted to gradually approach the target pressing state.

[0059] Step S25 , when F2 is equal to Fa, obtaining the second height H2 of the pressure head unit 11 .

[0060] Step S26, when the difference between the first height H1 and the second height H2 is within the preset range, the first inner ring 231 can be driven to continue to move toward the second inner ring 232. The preset range can be the spacing between the first inner ring 231 and the second inner ring 232 obtained based on measurement or experience. To make the first inner ring 231 and the second inner ring 232 abut, the distance that the first inner ring 231 moves toward the second inner ring 232 must be at least equal to the minimum value within the preset range. Through this step, it can be determined whether the pressing head unit 11 has reached the target pressing position.

[0061] In this embodiment, step S20 also includes step S27 to step S28, and each step is described in detail as follows:

[0062] Step S27, when the difference between the first height H1 and the second height H2 is less than the preset range, that is, the first inner ring 231 and the second inner ring 232 are not in contact, the pressing head unit 11 can be driven to move away from the second inner ring 232 to H1 and then steps S23 to S26 are repeated. Through this step, the press-fitting process can be fine-tuned to ensure the accuracy and stability of the press-fitting result. At the same time, this step can be repeated multiple times to ensure that all adjustable parts are adjusted as much as possible.

[0063] Step S28, when the number of repetitions reaches the preset number of times, an alarm signal is issued when a problem that cannot be solved by multiple adjustments occurs. Through this step, abnormal conditions in the press-fitting process can be discovered and handled in time to avoid causing greater losses.

[0064] In this embodiment, step S27 includes step S271 to step S273, and each step is described in detail as follows:

[0065] Step S271, when the difference between the first height H1 and the second height H2 is less than a preset range, the pressing head unit 11 can be driven to move to H1 away from the second inner ring 232. The pressing head unit 11 is returned to H1 as a reference point to facilitate determining whether the first inner ring 231 and the second inner ring 232 are in contact during the re-pressing process.

[0066] Step S272, when the pressure head unit 11 moves to H1 away from the second inner ring 232, the pressure head unit 11 is driven to rotate, and the first inner ring 231 and the roller 22 also rotate accordingly, thereby adjusting the positions of the first inner ring 231 and the roller 22 so that the parts of the two that are slightly skewed or stuck can return to normal during movement.

[0067] Step S273, when the pressure head unit 11 starts to rotate, repeat steps S23 to S26. Among them, step S25 includes:

[0068] Step S251: when F2=Fa, the pressure head unit 11 stops moving.

[0069] Step S252, after the pressure head unit 11 stops moving, the pressure head unit 11 stops rotating and obtains the second height H2 of the pressure head unit 11. Stopping the pressure head unit 11 from moving and then rotating can, on the one hand, make the obtained data more accurate, and on the other hand, maximize the effect of adjusting the state of the bearing assembly 02 by rotation.

[0070] In this embodiment, step S272 includes step S2721 to step S2725, and each step is described in detail as follows:

[0071] Step S2721, after the pressure head unit 11 moves to H1 away from the second inner ring 232, the outer ring unit 21 can be driven to rotate. The rotation of the outer ring unit 21 can drive the roller 22, the first inner ring 231 and the second inner ring 232 to rotate accordingly, thereby adjusting possible local skew or jam.

[0072] Step S2722 , when the outer ring unit 21 starts to rotate, the pressing head unit 11 is driven to move toward the press-fitting seat unit 12 .

[0073] Step S2723, after the pressing head unit 11 moves toward the press-fitting seat unit 12, a third pressure value F3 is obtained, wherein the third pressure value F3 is the pressure of the pressing head unit 11 on the inner ring unit 23.

[0074] Step S2724 , when F3 = Fa, that is, when the pressing head unit 11 moves to the critical point where the elastic module 122 is about to be compressed, the pressing head unit 11 is driven to move away from the second inner ring 232 to H1 .

[0075] Step S2725, after the pressing head unit 11 moves to H1 in a direction away from the second inner ring 232, the pressing head unit 11 is driven to rotate.

[0076] In another embodiment, the outer ring unit 21 and the pressure head unit 11 can rotate in the same direction, so that the inner ring unit 23 can rotate in different directions. By driving the outer ring unit 21 and the inner ring unit 23 to actively rotate respectively, and driving the inner ring unit 23 to rotate in different directions, different motion states of the bearing assembly 02 can be fine-tuned.

[0077] In this embodiment, the method for installing the bearing assembly 02 may further include step S40, which is described in detail as follows:

[0078] Step S40, after the pressing head unit 11 moves toward the inner ring unit 23 to the pressing state, the pressing head unit 11 can be driven to move to the initial position away from the second inner ring 232. Through this step, the entire pressing process can be completed, and the pressing head unit 11 can be restored to the initial state to prepare for the next pressing.
