Description

Technical Field

[0001] The present invention relates to the technical field of bearings, and particularly to a high-speed bearing with an adaptive function and its production equipment. Background Art

[0002] Bearings are the food of all industries. They are used to support rotating parts and are one of the key components of mechanical equipment. Any rotation requires the use of bearings. Any defect in the bearings can cause equipment failures and even serious accidents. One of the important factors to ensure the normal operation and long service life of bearings is to ensure good lubrication of the bearings through lubricating oil or grease. Bearings are divided into sliding bearings and rolling bearings. Due to the low friction coefficient, small power loss, and small starting resistance of rolling bearings, they are widely used and are suitable for high-speed rotation and occasions requiring low noise and low vibration. Moreover, they have been standardized and are professionally mass-produced and supplied. It can be said that with the development of bearings, rolling bearings have reached the peak of bearings.

[0003] The patent document with the patent number CN118560193A discloses a high-load hub bearing unit, including a bearing assembly and a transmission assembly. The bearing assembly is used to establish a rotational fit between the vehicle hub and the suspension, and the transmission assembly is used to establish a constant-velocity drive connection between the second bushing and the drive shaft. In the present invention, the sphere of the transmission assembly can be axially detached from the mounting bracket and the second bushing in the ball cage universal joint structure because the ball panel does not block the axial movement of the sphere after the sphere axially disengages from the ball panel in the axial direction of the ball socket. After the mounting bracket is detached from the sphere, by rotating the mounting bracket by a certain amplitude, the second ball can fall out of the first rolling groove and the third mounting groove to realize the detachment of the mounting bracket from the second bushing. The overall disassembly of the ball cage universal joint structure is labor-saving and convenient.

[0004] However, in the actual use process, the inventor found that the internal structures of some existing bearings are unreasonable, and during production, the filling and even spreading of grease are mainly completed manually or by a grease homogenizer, resulting in uneven grease spreading in the bearings and easy leakage. With the continuous development of industry, bearings are also developing from low speed to high speed. The uneven and easily leaked grease will cause high-speed bearings to be more prone to heat generation and excessive wear, leading to bearing damage and low service life. In particular, some bearings that are subject to both axial loads and radial loads are more likely to deform or even crack, resulting in easier leakage of the grease in the bearings and lower service life. Summary of the Invention

[0005] The object of the present invention is to address the deficiencies of the prior art. By providing two rolling components respectively connected to two mounting grooves on the outer shaft sleeve and both ends of the spherical structure on the inner shaft sleeve, the axial load and radial load between the outer shaft sleeve and the inner shaft sleeve are reduced, the stability of connection and transmission is improved. At the same time, the two oppositely arranged rolling components face the sealing cavity, and thus the grease filled into the sealing cavity through the filling holes can be directly and evenly attached to the two rolling components. The lubrication effect is good, the grease is uniform and not easily leaked, damage is avoided, and the service life is prolonged. Thereby, the problems of uneven grease, easy leakage, easy damage and low service life of existing high-speed bearings are solved.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] Embodiment 1

[0042] As Figures 1-4 shown, a high-speed bearing with an adaptive function includes:

[0043] On the inner walls at both ends, there are outer sleeves 11 each formed with an installation groove 111, an inner sleeve 12 rotatably arranged within the outer sleeve 11 and forming a sealing cavity 112 with the two installation grooves 111, two rolling components 13 oppositely arranged in the two installation grooves 111, a spherical structure 121 formed on the outer wall of the inner sleeve 12 and having both ends respectively abutted against the two rolling components 13, a plurality of connection grooves 122 formed at equal intervals along the circumferential direction of the outer sleeve 11 on the inner wall of the inner sleeve 12 and used for connecting external structures, a plurality of filling holes 113 formed at equal intervals along the circumferential direction of the inner sleeve 12 and penetrating through the outer sleeve 11 and used for filling grease into the sealing cavity 112, a sealing plug 114 arranged in the filling hole 113, two connecting plates 14 respectively arranged on the outer sleeve 11 and the inner sleeve 12 and located on both sides of the rolling component 13, and a plurality of installation holes 141 formed at equal intervals along the circumferential direction of the rolling component 13 on the connecting plate 14 and used for installing bolts 15.

[0044] In this embodiment, by arranging two rolling components 13 to respectively connect the two ends of the two installation grooves 111 on the outer sleeve 11 and the spherical structure 121 on the inner sleeve 12, the axial load and radial load between the outer sleeve 11 and the inner sleeve 12 are reduced, the connection and transmission stability are improved, easy damage is avoided, the service life is increased. At the same time, the two oppositely arranged rolling components 13 face the sealing cavity 112, so that the grease filled into the sealing cavity 112 through the filling hole 113 can be directly and evenly attached to the two rolling components 13, with good lubrication effect, the grease is uniform and not easy to leak, further avoiding easy damage and increasing the service life.

[0045] It should be noted that the number of installation holes 141 on the connecting plate 14 is preferably six, which improves the stability after installation and facilitates the positioning and stacking of the outer sleeve 11 and the inner sleeve 12 before subsequent assembly;

[0046] The sealing plug 114 is threadedly connected to the filling hole 113, with high sealing performance and connection stability.

[0047] Further, as Figures 4-5 shown, the rolling component 13 includes a cage 131 arranged in the installation groove 111, a plurality of rolling grooves 132 formed at equal intervals along the circumferential direction of the outer sleeve 11 on the cage 131, balls 133 arranged in the rolling grooves 132 and having both sides extending outside the cage 131 and respectively abutted against the installation groove 111 and the spherical structure 121, and a transmission channel 134 communicating between adjacent two rolling grooves 132 and used for transmitting grease as the balls 133 rotate.

[0048] In this embodiment, by arranging the transmission channel 134 to cooperate with the rotation of the balls 133, the movement of grease in each rolling groove 132 is realized, the fluidity of the grease is improved, and the lubrication effect is further improved.

[0049] It should be noted that the cage 131 is made of plastic, which is convenient for integral molding and has a certain deformation ability, facilitating production and assembly into the installation groove 111 after deformation.

[0050] Furthermore, as Figures 2-5 shown, on the inner wall of one end of the outer shaft sleeve 11 where the connecting plate 14 is provided, a first sealing block 115 is formed which abuts against the outer wall of the inner shaft sleeve 12 and is used to seal one end of the sealing cavity 112. On the outer wall of one end of the inner shaft sleeve 12 where the connecting plate 14 is provided, a second sealing block 123 is formed which abuts against the inner wall of the outer shaft sleeve 11 and is used to seal the other end of the sealing cavity 112.

[0051] In this embodiment, by arranging the first sealing block 115 and the second sealing block 123 at specific positions between the inner shaft sleeve 12 and the outer shaft sleeve 11 respectively, the sealing of the sealing cavity 112 is achieved, the swing between the outer shaft sleeve 11 and the inner shaft sleeve 12 is restricted, and the interference of the insertion connection between the inner shaft sleeve 12 and the outer shaft sleeve 11 is avoided, facilitating the assembly during production.

[0052] It should be noted that the spherical structure 121 is provided with a groove 124 connecting the two rolling components 13, improving the connection stability and further restricting the swing between the outer shaft sleeve 11 and the inner shaft sleeve 12;

[0053] In addition, after the sealing cavity 112 is filled with grease, the further filled grease can flow into the gaps between the first sealing block 115 and the inner shaft sleeve 12 and between the second sealing block 123 and the outer shaft sleeve 11, playing a good lubricating role and avoiding wear and heat generation.

[0054] Embodiment Two

[0055] As Figure 4 and Figures 6-7 shown, the present application also provides a bearing production device for producing the above-mentioned high-speed bearing with an adaptive function, including:

[0056] An assembly mechanism 2 for assembling the bearing 1, two forming mechanisms 3 arranged outside the assembly mechanism 2 and respectively used for forming the outer shaft sleeve 11 and the inner shaft sleeve 12, a discharging mechanism 4 arranged on the forming mechanism 3 and used for outputting the outer shaft sleeve 11 or the inner shaft sleeve 12, a carrying mechanism 5 movably arranged between the assembly mechanism 2 and the forming mechanism 3 and cooperating with the discharging mechanism 4 for positioning and carrying the outer shaft sleeve 11 or the inner shaft sleeve 12, a conveying mechanism 6 arranged outside the assembly mechanism 2 and used for conveying the rolling components 13, and a grasping mechanism 7 arranged on the assembly mechanism 2 and used for grasping the outer shaft sleeve 11, the inner shaft sleeve 12, the rolling components 13 and the bearing 1;

[0057] The assembling mechanism 2 includes a press 21, a first supporting component 22 which is movably arranged on the press 21 and cooperates with the filling hole 113 to position and support the outer shaft sleeve 11, a second supporting component 23 which is movably and rotatably arranged on the press 21 and cooperates with the connecting groove 122 to position and support the inner shaft sleeve 12, and an installation component 24 which is arranged outside the press 21 and is used for installing the bolt 15 in the installation hole 141. When the second supporting component 23 rotates to directly above the first supporting component 22, after the outer shaft sleeve 11 and the inner shaft sleeve 12 are extruded and assembled by the press 21, the first supporting component 22 positions the filling hole 113 and fills the lubricating grease into the sealing cavity 112, and then the installation component 24 positions and installs the sealing plug 114 into the filling hole 113.

[0058] In this embodiment, by arranging the carrying mechanism 5 to cooperate with the discharging mechanism 4 to position and carry the outer shaft sleeve 11 and the inner shaft sleeve 12 formed in the two forming mechanisms 3 and move and convey them to the assembling mechanism 2, and then cooperating with the grasping mechanism 7, the outer shaft sleeve 11 and the inner shaft sleeve 12 in the carrying mechanism 5 can be respectively positioned and grasped onto the first supporting component 22 and the second supporting component 23 for positioning and supporting. Then, with the assistance of the press 21, after the outer shaft sleeve 11 and the inner shaft sleeve 12 with the bolt 15 installed by the installation component 24 are extruded and assembled, the first supporting component 22 positioning the filling hole 113 can directly fill the lubricating grease into the sealing cavity 112, and the installation component 24 can position and install the sealing plug 114 into the filling hole 113, realizing the automatic production of the bearing 1. And during the whole production process, the inner shaft sleeve 12 and the outer shaft sleeve 11 are both in a positioned state, which is convenient for assembly and improves the production efficiency.

[0059] It should be noted that the forming mechanism 3 is used for turning the outer shaft sleeve 11 and the inner shaft sleeve 12 and for positioning and drilling a plurality of installation holes 141 on the connecting plate 14. And a set of forming mechanisms 3 can simultaneously form a plurality of outer shaft sleeves 11 or inner shaft sleeves 12 to adapt to the assembling speed of the assembling mechanism 2, ensuring the production efficiency and continuity; the press 21 extrudes and assembles the inner shaft sleeve 12 into the inner shaft sleeve 12 through the hydraulic principle; the installation component 24 is used for directionally conveying the bolt 15 and the sealing plug 114 similar to a lead screw, and then threadedly connecting the bolt 15 in the installation hole 141 and threadedly connecting the sealing plug 114 in the filling hole 113; the forming mechanism 3, the press 21 and the installation component 24 themselves and their installation methods are all prior arts and will not be elaborated in detail here;

[0060] In addition, the discharging mechanism 4 is used for positioning and outputting the formed outer shaft sleeve 11 or inner shaft sleeve 12, and at the same time, it can position and convey the blank of the outer shaft sleeve 11 or inner shaft sleeve 12 to the forming mechanism 3.

[0061] Further, as Figures 10-12As shown in the figure, the bearing mechanism 5 includes a bearing cart 51 movably arranged between the assembling mechanism 2 and a set of forming mechanisms 3 and used for array-bearing multiple layers of outer bushings 11 or inner bushings 12, a bearing plate 221 arranged to move up and down in the bearing cart 51, and a plurality of positioning columns 224 penetrating through the bearing plate 221 and arranged in the bearing cart 51 and used for positioning at least two mounting holes 141 on a connecting plate 14. Four mounting holes 141 on the connecting plate 14 of one layer are respectively aligned with one mounting hole 141 on the four connecting plates 14 of the adjacent other layer. Furthermore, the mounting holes 141 aligned on multiple layers of connecting plates 14 can be positioned by one positioning column 224. At the same time, the outer bushings 11 and inner bushings 12 of adjacent two layers are arranged oppositely. The outer bushings 11 and inner bushings 12 of one layer are inserted between the four connecting plates 14 of the adjacent other layer, so that the adjacent two layers of connecting plates 14 support each other.

[0062] In this embodiment, by arranging the bearing plate 221, multiple layers of outer bushings 11 or inner bushings 12 in a specific arrangement are supported in the bearing cart 51, with high space utilization rate, enabling the bearing cart 51 to carry more outer bushings 11 or inner bushings 12. At the same time, the positioning columns 224 are supplemented to position the mounting holes 141 on multiple layers of outer bushings 11 or inner bushings 12 in a specific arrangement, facilitating the insertion and positioning between the positioning columns 224 and the mounting holes 141. With good positioning effect, the use of the positioning columns 224 is reduced.

[0063] Specifically, during use, the bearing cart 51 is moved to the outside of the forming mechanism 3 and the bearing plate 221 is moved upward. The discharging mechanism 4 spreads a layer of the inner bushings 12 or outer bushings 11 formed on the forming mechanism 3 upward in an array on the bearing plate 221, and two mounting holes 141 on each inner bushing 12 or outer bushing 11 are positioned by two positioning columns 224. Then the bearing plate 221 is moved downward, and the discharging mechanism 4 inserts the inner bushings 12 or outer bushings 11 formed on the forming mechanism 3 downward between the four adjacent connecting plates 14 of the upper layer until a layer of inner bushings 12 or outer bushings 11 is spread downward in an array. This is repeated in sequence, and multiple layers of outer bushings 11 or inner bushings 12 can be array-bearing in the bearing cart 51. When the bearing cart 51 is moved to the outside of the assembling mechanism 2 and cooperates with the grasping mechanism 7, as the inner bushings 12 or outer bushings 11 of each layer are grabbed out, the bearing plate 221 moves upward at intervals for a certain distance, facilitating the grasping of the grasping mechanism 7.

[0064] It should be noted that the wheels under the bearing cart 51 are driven by electric positioning to position and move between the assembling mechanism 2 and multiple forming mechanisms 3 to achieve automated production.

[0065] Furthermore, as Figure 13As shown in the figure, the discharging mechanism 4 includes a moving frame 41 movably arranged between the forming mechanism 3 and the carrier vehicle 51, two first clamping arms 42 that are openable and rotatably arranged on the moving frame 41 and are used to clamp the outer walls of the outer shaft sleeve 11 and the inner shaft sleeve 12, and a plurality of first support arms 43 that move up and down and are radially openable and arranged on the moving frame 41 and are used to support the inner walls of the outer shaft sleeve 11 and the inner shaft sleeve 12.

[0066] In this embodiment, by setting the first clamping wall that is openable and rotatable to position and clamp the outer walls of the outer shaft sleeve 11 and the inner shaft sleeve 12 facing up or down, and supplemented by the first support arms 43 that are radially openable, the inner walls of the outer shaft sleeve 11 and the inner shaft sleeve 12 can be positioned and supported. Furthermore, in cooperation with the movement of the moving frame 41 and the first support arms 43, the outer shaft sleeve 11 and the inner shaft sleeve 12 can be conveyed up or down into the carrier vehicle 51, avoiding interference between the discharging mechanism 4 and the positioning column 224, other outer shaft sleeves 11 and other inner shaft sleeves 12 in the carrier vehicle 51.

[0067] Furthermore, as Figure 14 shown, the grasping mechanism 7 includes a rotating frame 71 rotatably arranged between the press 21, the carrier vehicle 51 and the conveying mechanism 6, two second clamping arms 72 that are openable and rotatably arranged on the rotating frame 71 and are used to clamp the outer walls of the outer shaft sleeve 11 and the inner shaft sleeve 12, a plurality of second support arms 73 that move up and down and are radially openable and arranged on the rotating frame 71 and are used to support the inner walls of the outer shaft sleeve 11, the inner shaft sleeve 12 and the rolling component 13, and pressing ridges 74 arranged on each second support arm 73 and used to press the rolling component 13 into the installation groove 111.

[0068] In this embodiment, after positioning and supporting the outer shaft sleeve 11 and the inner shaft sleeve 12 in the carrier vehicle 51 by setting the second support arms 73 that move up and down and are radially openable, and supplemented by the openable second clamping walls to position and clamp the outer walls of the outer shaft sleeve 11 and the inner shaft sleeve 12 on the second support arms 73, and then through the rotation of the rotating frame 71 and the second clamping arms 72, the outer shaft sleeve 11 and the inner shaft sleeve 12 can be respectively positioned and grasped upwards onto the first support assembly 22 and the second support assembly 23, avoiding interference between the grasping mechanism 7 and the positioning column 224, other outer shaft sleeves 11 and other inner shaft sleeves 12 in the carrier vehicle 51. At the same time, the second support arms 73 that move up and down and are radially openable cooperate with the rotating rotating frame 71 to support the ball 133 assembly on the conveying mechanism 6 onto the first bearing assembly. Furthermore, by moving the second support arms 73 up and down, the pressing ridges 74 can be used to press the ball 133 assembly into the installation groove 111 of the inner shaft sleeve 12.

[0069] It should be noted that elastic layers made of rubber or latex are provided on the inner sides of the first clamping arm 42 and the second clamping arm 72, and on the outer sides of the first support arm 43 and the second support arm 73 to improve the stability of clamping and support. This is prior art and not shown in the Chinese text of the drawings.

[0070] Furthermore, as Figure 15 shown, the conveying mechanism 6 includes a conveying component 61 arranged outside the press 21 and used for conveying the rolling component 13, an LL-shaped turning plate 62 rotatably arranged on the conveying component 61 and used for turning over the rolling component 13, and an arc-shaped positioning plate 63 arranged on the conveying component 61 and used for positioning the rolling component 13.

[0071] In this embodiment, while the conveying component 61 conveys the rolling component 13, the LL-shaped turning plate 62 is assisted to reverse the rolling component 13 backward to avoid reversing during subsequent assembly, and then the arc-shaped positioning plate 63 is used to position the rolling component 13, facilitating the conveying and grasping mechanism 7 to perform grasping.

[0072] Specifically, during use, the LL-shaped turning plate 62 rotates until it abuts against the conveying component 61. A rolling component 13 is conveyed to the LL-shaped turning plate 62 through the conveying component 61. Then, by rotating the LL-shaped turning plate 62, the rolling component 13 can be turned over and positioned by the arc-shaped positioning plate 63. Next, the LL-shaped turning plate 62 rotates above the conveying component 61, and the next rolling component 13 passes below the LL-shaped turning plate 62 and is positioned by the arc-shaped positioning plate 63.

[0073] It should be noted that the conveying component 61 is a conveyor belt, which is not only used for conveying the rolling component 13 at one end, but also used for outputting the assembled bearing 1 in cooperation with the grasping mechanism 7 at the other end.

[0074] Furthermore, as Figure 8 shown, the first support component 22 includes a support plate 52 movably arranged on the press 21, a first support seat 222 axially rotatably arranged on the support plate 52 and used for supporting the outer shaft sleeve 11, a plurality of positioning holes 223 formed on the first support seat 222 and used for positioning the bolts 15, a plurality of positioning rods arranged on the support plate 52 in a radially opening and closing manner and inserted into the filling holes 113, and a filling channel 225 penetrating through the inside of the positioning rods and used for filling lubricating grease into the sealing cavity 112 in cooperation with an extruder.

[0075] In this embodiment, by providing a plurality of positioning rods that open and close radially and are inserted into a plurality of filling holes 113, the outer shaft sleeve 11 is positioned on the first support seat 222, facilitating the connection of the bolt 15 in the mounting hole 141 and the positioning hole 223 for secondary positioning of the outer shaft sleeve 11. Furthermore, after filling the sealing cavity 112 with grease through the filling channel 225 in the positioning rod, the secondary-positioned outer shaft sleeve 11 facilitates the installation of the sealing plug 114.

[0076] Specifically, during use, after the moving support plate 52 cooperates with the grasping mechanism 7 to grasp the outer shaft sleeve 11 onto the first support seat 222, a plurality of positioning rods are closed radially and inserted into a plurality of filling holes 113 to position the outer shaft sleeve 11. Then, the installation assembly 24 installs the bolt 15 in two adjacent mounting holes 141 and performs secondary positioning through the positioning hole 223. After that, the plurality of positioning rods open radially. While the first support seat 222 rotates, it cooperates with the installation assembly 24 to install the bolt 15 in another mounting hole 141. Then, after the rolling assembly 13 and the inner shaft sleeve 12 are installed in the outer shaft sleeve 11 in sequence, the plurality of positioning rods are closed radially and inserted into the positioned filling holes 113. Furthermore, grease is filled into the sealing cavity 112 through the filling channel 225. Finally, after the plurality of positioning rods open radially, while the first support seat 222 rotates, it cooperates with the installation assembly 24 to position and install the sealing plug 114 in each filling hole 113.

[0077] It should be noted that the extruder pumps grease into the filling channel 225 through a pump and a pipeline. Its itself and the installation method are both prior arts and are not shown in the drawings, so no detailed description is given here.

[0078] Furthermore, as Figure 9 shown, the second support assembly 23 includes a support frame 231 that is movably and rotatably arranged on the press 21, a second support seat 232 that is axially rotatably arranged on the support frame 231 and is used to support the inner shaft sleeve 12, a support rod 233 that is arranged on the support seat and inserted into the inner shaft sleeve 12, a plurality of connecting rods 234 that are rotatably arranged on the support rod 233 and are respectively connected to a plurality of connecting grooves 122, and an elastic member that is arranged on the support rod 233 and is used to force the connecting rod 234 to rotate away from the support rod 233.

[0079] In this embodiment, by providing an elastic member to force the rotating connecting rod 234 to be connected in the connecting groove 122, the inner shaft sleeve 12 is positioned and connected to the second support seat 232, facilitating the rotating second support seat 232 to cooperate with the installation assembly 24 to achieve the positioning and installation of the bolt 15. At the same time, with the aid of the rotating support frame 231, the positioning between the inner shaft sleeve 12 and the outer shaft sleeve 11 is achieved.

[0080] Specifically, during use, the inner bushing 12 is grasped by the grasping mechanism 7 and inserted into the support rod 233. The inner bushing 12 forces the connecting rod 234 to rotate, and the elastic member deforms until the support rod 233 is completely inserted into the inner bushing 12. Then, the elastic member restores its deformation, forces the connecting rod 234 to rotate and reset, and connects to the connecting groove 122 to position and connect the inner bushing 12 to the second support base 232. Next, the second support base 232 rotates, and the mounting assembly 24 positions and installs the mounting bolts 15 in the plurality of mounting holes 141. Finally, when the support frame 231 is rotated until the inner bushing 12 is positioned directly above the outer bushing 11, the press 21 presses the inner bushing 12 downward into the outer bushing 11. The inner bushing 12 forces the connecting rod 234 to rotate, and the elastic member deforms until the support rod 233 disengages from the inner bushing 12. Then, the elastic member restores its deformation and forces the connecting rod 234 to rotate and reset.

[0081] It should be noted that the elastic member is a torsion spring, a leaf spring, etc. Its itself and the installation method are both prior arts and are not shown in the drawings, so no detailed description will be given here.

[0082] Working process:

[0083] First, the outer bushing 11 and the inner bushing 12 formed by the two forming mechanisms 3 are respectively positioned and conveyed to the two loading mechanisms 5 for positioning and loading by the feeding mechanism 4. Then, the two loading mechanisms 5 are moved to position and convey the outer bushing 11 and the inner bushing 12 to both sides of the assembling mechanism 2.

[0084] Next, the grasping mechanism 7 respectively positions and grasps the outer bushing 11 and the inner bushing 12 in the two loading mechanisms 5 onto the first support assembly 22 and the second support assembly 23 for positioning and supporting. Then, the mounting assembly 24 installs the mounting bolts 15 in the mounting holes 141 on the outer bushing 11 and the inner bushing 12. The grasping mechanism 7 positions and grasps the rolling assembly 13 conveyed by the conveying mechanism 6 and installs it into the outer bushing 11.

[0085] Then, after the second support assembly 23 is rotated to directly above the first support assembly 22, the press 21 presses the inner bushing 12 to move into the outer bushing 11, and the outer bushing 11 and the inner bushing 12 are extrusion-assembled.

[0086] Finally, the first support assembly 22 positioning the filling hole 113 can directly fill the lubricating grease into the sealing cavity 112. Then, after positioning and installing the sealing plug 114 into the filling hole 113 through the mounting assembly 24, the grasping mechanism 7 can grasp the bearing 1 produced on the first support assembly 22 for blanking.
