[0054] During the installation of the universal joint bearing assembly, Figure 5 As shown, the dustproof unit 13 is usually required to be restricted between the sealing unit 12 and the sleeve unit 11, and the dustproof unit 13 is spaced axially and radially relative to the sealing unit 12. However, during the installation process, relative sliding may occur between the dustproof unit 13 and the sealing unit 12, so that the contact surface between the sealing unit 12 and the dustproof unit 13 is worn, thereby affecting the sealing performance of the sealing unit 12. Figure 2As shown, the universal joint bearing assembly installation system may include a bearing assembly 01, a first feeding assembly 02, a second feeding assembly 03, a third feeding assembly 04, and a pressing assembly 05. The bearing assembly 01 may include a sleeve unit 11, a sealing unit 12, and a dustproof unit 13. The pressing assembly 05 may include a pressing unit 52 and a clamping unit 53. The pressing unit 52 may provide a pressing force to the sealing unit 12 during the press-fitting process, and the clamping unit 53 may provide a clamping force to the dustproof unit 13, and drive the dustproof unit 13 to move through the clamping unit 53. This embodiment provides a universal joint bearing assembly installation method, such as Figure 1 As shown, the method for installing a universal joint bearing assembly may include steps S10 to S40, and each step is described in detail as follows:

[0055] In step S10, based on the bearing assembly 01 installation instruction trigger, the first feeding assembly 02 can move the sleeve unit 11 to the pressure seat unit 51, and the second feeding assembly 03 moves the sealing unit 12 and the dustproof unit 13 to the third feeding seat 41 of the third feeding assembly 04, to facilitate the subsequent installation of the universal joint bearing assembly.

[0056] In step S20 , based on the sealing unit 12 and the dustproof unit 13 moving to the third feeding seat 41 , the third feeding assembly 04 can move the sealing unit 12 and the dustproof unit 13 to the grasping position to facilitate the clamping unit 53 to clamp the sealing unit 12 and the dustproof unit 13 .

[0057] In step S30 , based on the sealing unit 12 and the dustproof unit 13 moving to the grasping position, the clamping unit 53 can clamp the dustproof unit 13 , so that the clamping unit 53 can provide a clamping force to the sealing unit 12 and the dustproof unit 13 .

[0058] Step S40, based on the clamping unit 53 clamping the dustproof unit 13, the third feeding assembly 04 can be moved to the initial position, and the pressing unit 52 can press one end of the sealing unit 12 to the installation position of the sleeve unit 11. The installation position includes the axial and radial spacing of the dustproof unit 13 and the sealing unit 12 in the sealing unit 12. During the pressing process, the dustproof unit 13 can be partially abutted against the sealing unit 12, and the clamping unit 53 continues to provide clamping force to the dustproof unit 13 during the pressing process, thereby increasing the friction between the sealing unit 12 and the dustproof unit 13, reducing the relative sliding between the dustproof unit 13 and the sealing unit 12 during the pressing process of the sealing unit 12, and preventing the burrs at the contact point between the dustproof unit 13 and the sealing unit 12 from causing the sealing unit 12 to wear, thereby affecting the sealing performance of the sealing unit 12. f1+f2<F, f1 is the friction force between the clamping unit 53 and the dustproof unit 13, f2 is the friction force between the sleeve unit 11 and the sealing unit 12, and F is the pressing force of the pressing unit 52. The pressing force is greater than the sum of the friction force between the clamping unit 53 and the dustproof unit 13 and the friction force between the sleeve unit 11 and the sealing unit 12, so that the sealing unit 12 and the dustproof unit 13 can move relative to the sleeve unit 11, so that the sealing unit 12 and the dustproof unit 13 can be installed with the bearing unit.

[0059] In this embodiment, step S30 may include step S31 to step S34, and each step is described in detail as follows:

[0060] In step S31, based on the sealing unit 12 and the dustproof unit 13 moving to the grasping position, the pressing unit 52 can be controlled to move to the first set position. The first set position may include the outer peripheral wall of the first pressing head 523 of the pressing unit 52 and the inner peripheral wall of the dustproof unit 13 being spaced apart, and the outer peripheral wall of the second pressing head 524 of the pressing unit 52 abutting against the inner peripheral wall of the sealing unit 12.

[0061] In step S32, based on the pressing unit 52 moving to the first set position, the first oil injection hole 525 of the pressing unit 52 can spray grease to the inner peripheral wall of the dustproof unit 13. By injecting grease to the inner peripheral wall of the dustproof unit 13, lubrication is provided to the dustproof unit 13, thereby reducing the wear of the dustproof unit 13 and the sealing unit 12 during the press-fitting process.

[0062] In step S33, based on the first oil injection hole 525, grease is sprayed onto the inner wall of the dustproof unit 13, and the pressing unit 52 can move to the second set position. Figure 6As shown, the second set position may include the end of the first pressing head 523 abutting against the end of the sealing unit 12, the outer peripheral wall of the second pressing head 524 abutting against the inner peripheral wall of the sealing unit 12, and the cover ring 132 of the dustproof unit 13 abutting against the sealing unit 12, so as to fix the relative position of the sealing unit 12 and the dustproof unit 13, thereby preventing the sealing unit 12 and the dustproof unit 13 from sliding relative to each other, and preventing the burrs at the contact point between the dustproof unit 13 and the sealing unit 12 from causing wear of the sealing unit 12, thereby affecting the sealing performance of the sealing unit 12. In step S34, based on the pressing unit 52 moving to the second set position, the clamping unit 53 can clamp the dustproof unit 13, so that the clamping unit 53 can provide clamping force to the sealing unit 12 and the dustproof unit 13, thereby increasing the friction between the sealing unit 12 and the dustproof unit 13, reducing the relative sliding between the dustproof unit 13 and the sealing unit 12 during the pressing process of the sealing unit 12, and preventing the burrs at the contact point between the dustproof unit 13 and the sealing unit 12 from causing wear of the sealing unit 12, thereby affecting the sealing performance of the sealing unit 12.

[0063] In this embodiment, step S40 may include step S41 to step S44, and each step is described in detail as follows:

[0064] In step S41 , based on the clamping unit 53 clamping the dustproof unit 13 , the third feeding assembly 04 can move to the initial position.

[0065] In step S42 , based on the movement of the third feeding assembly 04 , the pressing unit 52 and the clamping unit 53 can simultaneously move a set distance toward the sleeve unit 11 to prevent the dustproof unit 13 from falling off during the movement, thereby facilitating the subsequent pressing of the sealing unit 12 and the sleeve unit 11 .

[0066] In step S43, based on the pressing unit 52 and the clamping unit 53 moving a set distance toward the direction close to the sleeve unit 11, the clamping unit 53 can stop moving and the clamping unit 53 reduces the clamping force on the dustproof unit 13 to a set threshold value, and provides clamping force to the dustproof unit 13 so that the friction force between the dustproof unit 13 and the clamping unit 53 can offset the downward movement of the dustproof unit 13 due to gravity. In the process of the pressing unit 52 pressing down the sealing unit 12, the clamping force of the clamping unit 53 is reduced, so that the sealing unit 12 can drive the dustproof unit 13 to move in the pressing direction while keeping the first sealing body 121 of the sealing unit 12 in contact with the cover ring 132 of the dustproof unit 13, thereby avoiding relative movement between the sealing unit 12 and the dustproof unit 13, and preventing the burrs at the contact between the dustproof unit 13 and the sealing unit 12 from causing wear of the sealing unit 12, thereby affecting the sealing performance of the sealing unit 12.

[0067] In step S44, based on the clamping unit 53 stopping moving and the clamping unit 53 reducing the clamping force on the dustproof unit 13 to the set threshold, the pressing unit 52 can press one end of the sealing unit 12 to the installation position of the sleeve unit 11, and the clamping unit 53 releases the dustproof unit 13. Wherein, the installation position includes the axial and radial spacing of the dustproof unit 13 and the sealing unit 12 in the sealing unit 12. f1+f2<F, f1 is the friction force between the clamping unit 53 and the dustproof unit 13, f2 is the friction force between the sleeve unit 11 and the sealing unit 12, and F is the pressing force of the pressing unit 52. The larger pressing force allows the sealing unit 12 and the dustproof unit 13 to move relative to the sleeve unit 11, so that the sealing unit 12 and the dustproof unit 13 can be installed with the bearing unit.

[0068] In this embodiment, step S40 may further include step S45 and step S46, each of which is described in detail as follows:

[0069] In step S45, based on the process of the pressing unit 52 and the clamping unit 53 moving toward the direction close to the sleeve unit 11, grease can be injected into the inner circumferential wall of the first sealing body 121 of the sealing unit 12 to a first set value through the first oil filling hole 525 of the pressing unit 52. By injecting grease into the first sealing body 121 during the downward movement, since the grease adheres to the first sealing body 121, the weight of the grease can be used to increase the pressure of the sealing unit 12 on the dustproof unit 13, so that the sealing unit 12 and the dustproof unit 13 fit more closely, further preventing relative displacement between the dustproof unit 13 and the sealing unit 12, thereby causing burrs at the contact point between the dustproof unit 13 and the sealing unit 12 to cause wear of the sealing unit 12, affecting the sealing performance of the sealing unit 12.

[0070] In step S46, based on the first oil injection hole 525 injecting grease into the inner circumferential wall of the first sealing body 121 to the first set value and the pressing unit 52 pressing one end of the sealing unit 12 to the installation position of the sleeve unit 11, the first oil injection hole 525 can inject grease into the inner circumferential wall of the first sealing body 121 to the second set value, and the second oil injection hole 526 of the pressing unit 52 injects grease into the inner circumferential wall of the sleeve unit 11 to the third set value. It plays a certain lubricating role on the first sealing body 121 and the sleeve unit 11, preventing wear between the first sealing body 121 and the sleeve unit 11. Among them, the second set value can be greater than the first set value.

[0071] In this embodiment, the clamp 532 of the clamping unit 53 in step S30 can abut against the outer peripheral side of one end of the cover body 131 of the dustproof unit 13 close to the cover ring 132 of the dustproof unit 13. It is ensured that the cover ring 132 can always abut against the first sealing body 121, thereby increasing the friction between the dustproof unit 13 and the sealing unit 12, reducing the relative movement of the dustproof unit 13 and the sealing unit 12, and thus ensuring the coaxiality of the dustproof unit 13 and the sealing unit 12. Since the inner part of the cover body 131 of the dustproof unit 13 close to the cover ring 132 of the dustproof unit 13 is thicker, the abutment between the clamp 532 of the clamping unit 53 and the cover body 131 of the dustproof unit 13 is close to the cover ring 132 of the dustproof unit 13, and the force arm between the force-bearing position and the abutment is short, which can prevent the dustproof unit 13 from being deformed due to excessive clamping force.

[0072] In this embodiment, step S10 may include step S11 and step S12, and each step is described in detail as follows:

[0073] In step S11, based on the triggering of the installation instruction of the bearing assembly 01, the first feeding assembly 02 can move the sleeve unit 11 to the positioning position of the press seat unit 51. The positioning position can include the positioning rod 512 of the press seat unit 51 passing through the positioning hole 113 of the sleeve unit 11, so that the relative position of the sleeve unit 11 is fixed by the positioning rod 512, which is convenient for the subsequent installation of the sleeve unit 11.

[0074] In step S12, based on the process of the first feeding assembly 02 moving the sleeve unit 11 to the pressing seat unit 51, the second feeding assembly 03 can move the sealing unit 12 and the dustproof unit 13 to the third feeding seat 41 of the third feeding assembly 04. Among them, the dustproof unit 13 can be sleeved on the sealing unit 12.

[0075] In this embodiment, the positioning position in step S11 may also include one end of the support plate 513 of the press seat unit 51 abutting against the circumference of one end of the positioning rod 512 extending out of the positioning hole 113, and one side of the support plate 513 may abut against the sleeve body 111 of the sleeve unit 11. This can increase the structural strength of the positioning rod 512 and prevent the positioning rod 512 from being damaged during the press-fitting process of the sleeve unit 11.

[0076] In this embodiment, step S20 may include step S21 to step S22, and each step is described in detail as follows:

One end of the first chamber is connected to an external oil storage device through a pipeline, and the other end is connected to the second chamber. One end of the first oil filling hole 525 is connected to the first chamber, and the other end penetrates the first pressing head 523 along the radial direction of the first pressing head 523 to communicate with the outside. One end of the second oil injection hole 526 is connected to the second chamber, and the other end extends obliquely in a direction away from the first pressing head 523 and penetrates the second pressing head 524 to communicate with the outside. The pressing unit 52 can provide a pressing force during the press-fitting process. The larger pressing force allows the sealing unit 12 and the dustproof unit 13 to move relative to the sleeve unit 11, so that the sealing unit 12 and the dustproof unit 13 can be installed with the bearing unit.

[0090] The clamping unit 53 may include a clamping drive portion 531 and a chuck 532. One end of the clamping drive portion 531 is detachably connected to one side of the pressing seat 522, and the other end is drivingly connected to one end of the chuck 532. The chuck 532 is spaced apart from the outer peripheral wall of the first pressing head 523. The chuck 532 moves along the axial or radial direction of the first pressing head 523. The two chucks 532 are symmetrically arranged on both sides of the first pressing head 523. By the clamping unit 53 continuing to provide a clamping force to the dustproof unit 13 during the pressing process, the relative sliding between the dustproof unit 13 and the sealing unit 12 during the pressing process of the sealing unit 12 is reduced, and the burrs at the contact point between the dustproof unit 13 and the sealing unit 12 are prevented from causing wear of the sealing unit 12, thereby affecting the sealing performance of the sealing unit 12.

[0091] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
