Description

Technical Field

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

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

[0003] Patent document with patent number CN118560193A discloses a high-load hub bearing unit, including a bearing assembly and a transmission assembly, wherein the bearing assembly is used to establish a rotational fit between the automobile wheel hub and the suspension, and the transmission assembly is used to establish a constant-speed transmission connection between the second sleeve and the drive shaft. In the present invention, after the ball sleeve axially separates from the ball panel, the ball panel does not form an obstacle to the axial movement of the ball, so that the ball in the ball cage universal joint structure is axially separated and disassembled from the mounting frame and the second sleeve. After the mounting frame is separated from the ball, the mounting frame is rotated to a certain amplitude so that the second ball falls out of the first rolling groove and the third mounting groove to realize the disassembly of the mounting frame from the second sleeve, and the overall disassembly of the ball cage universal joint structure is labor-saving and convenient.

[0004] However, during actual use, the inventors found that the internal structure of some existing bearings is unreasonable, and the grease is mainly filled and spread manually or by a grease spreader during production, resulting in uneven grease application in the bearings and easy leakage. With the continuous development of industry, bearings have also developed from low speed to high speed. Uneven and leaky grease will cause high-speed bearings to be more prone to heat and excessive wear, which will cause bearing damage and a shorter service life. In particular, some bearings that are subject to both axial and radial loads are more prone to deformation and even cracks, causing the grease in the bearings to leak more easily and have a shorter service life. Summary of the invention

At the same time, the two rolling assemblies arranged opposite to each other face the sealing cavity, and the grease filled into the sealing cavity through the filling hole can be directly and evenly attached to the two rolling assemblies, so that the lubrication effect is good, the grease is uniform and not easy to leak, and easy damage is avoided, and the service life is increased.

[0046] Further, if Figure 10-12As shown, the supporting mechanism 5 includes a supporting vehicle 51 which is movably arranged between the assembling mechanism 2 and a group of forming mechanisms 3 and is used for array-carrying multiple layers of outer sleeves 11 or inner sleeves 12, a supporting plate 221 which is movably arranged in the supporting vehicle 51 and an upper and lower portion thereof, and a plurality of positioning columns 224 which penetrate the supporting plate 221 and are arranged in the supporting vehicle 51 and are used for positioning at least two mounting holes 141 on a connecting plate 14, and the four mounting holes 141 on the connecting plate 14 of one layer are respectively aligned with the mounting holes 141 on the four connecting plates 14 of another adjacent layer, and then the aligned mounting holes 141 on the multiple layers of connecting plates 14 are positioned by a positioning column 224, and at the same time, the outer sleeves 11 and the inner sleeves 12 of two adjacent layers are arranged opposite to each other, and the outer sleeves 11 and the inner sleeves 12 of one layer are inserted between the four connecting plates 14 of another adjacent layer so that the two adjacent connecting plates 14 support each other.

The LL-shaped flip plate 62 is then rotated to flip the rolling component 13 and then position it through the arc-shaped positioning plate 63. The LL-shaped flip plate 62 then rotates to the top of the conveying component 61, and the next rolling component 13 passes under the LL-shaped flip plate 62 and is then positioned through the arc-shaped positioning plate 63.

[0058] It should be noted that the conveying assembly 61 is a conveyor belt, not only one end of which is used to convey the rolling assembly 13 , but also the other end cooperates with the grabbing mechanism 7 to output the assembled bearing 1 .

[0059] Further, if Figure 8 As shown, the first support assembly 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 to support the outer sleeve 11, a plurality of positioning holes 223 formed on the first support seat 222 and used to position the bolts 15, a plurality of positioning rods radially opened and closed on the support plate 52 and inserted into the filling holes 113, and a filling channel 225 that passes through the interior of the positioning rods and cooperates with the extruder to fill grease into the sealing cavity 112.

[0060] In this embodiment, a plurality of radially opened and closed positioning rods are provided so as to be inserted into a plurality of filling holes 113 to position the outer sleeve 11 on the first support seat 222, so as to facilitate connecting the bolts 15 in the mounting holes 141 and the positioning holes 223 to perform secondary positioning of the outer sleeve 11. After the grease is filled into the sealing cavity 112 with the aid of the filling channel 225 in the positioning rod, the secondary positioned outer sleeve 11 facilitates the installation of the sealing plug 114.

[0061] In detail, when in use, after the mobile support plate 52 cooperates with the grabbing mechanism 7 to grab the outer sleeve 11 onto the first support seat 222, multiple positioning rods are radially closed and inserted into multiple filling holes 113 to position the outer sleeve 11, and then the installation component 24 installs the bolts 15 in the two adjacent mounting holes 141 and after a second positioning through the positioning holes 223, multiple positioning rods are radially opened, and the first support seat 222 rotates while cooperating with the installation component 24 to install the bolts 15 in the other mounting holes 141, and then the rolling component 13 and the inner sleeve 12 are installed in the outer sleeve 11 in turn, multiple positioning rods are radially closed and inserted into the multiple positioned filling holes 113, and then grease is filled into the sealing cavity 112 through the filling channel 225, and finally, after multiple positioning rods are radially opened, the first support seat 222 rotates while cooperating with the installation component 24 to position and install the sealing plug 114 in each filling hole 113.

[0062] It should be noted that the extruder squeezes grease into the filling channel 225 through a pump and a pipeline. The extruder itself and the installation method are both existing technologies, which are not drawn in the drawings and will not be described in detail here.

[0063] Further, if Fig. 9 As 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 sleeve 12, a support rod 233 that is arranged on the support seat and inserted into the inner 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 in a direction away from the support rod 233.

[0064] In this embodiment, an elastic member is provided to force the rotating connecting rod 234 to be connected to the connecting groove 122 to position the inner sleeve 12 on the second support seat 232, so that the rotating second support seat 232 cooperates with the installation assembly 24 to realize the positioning and installation of the bolt 15, and at the same time, the positioning between the inner sleeve 12 and the outer sleeve 11 is realized with the assistance of the rotating support frame 231.

[0065] In detail, when in use, the inner sleeve 12 is grasped and inserted into the support rod 233 through the grasping mechanism 7, the inner sleeve 12 forces the connecting rod 234 to rotate, and the elastic member is deformed until the support rod 233 is fully inserted into the inner sleeve 12. The elastic member recovers the deformation and forces the connecting rod 234 to rotate and reset, and then connects to the connecting groove 122 to position the inner sleeve 12 on the second support seat 232. Then the second support seat 232 is rotated, and the mounting assembly 24 is able to position the mounting bolts 15 in multiple mounting holes 141. Finally, the support frame 231 is rotated until the inner sleeve 12 is positioned directly above the outer sleeve 11, and the press 21 presses the inner sleeve 12 downward inside the outer sleeve 11. The inner sleeve 12 forces the connecting rod 234 to rotate, and the elastic member is deformed until the support rod 233 is separated from the inner sleeve 12. The elastic member recovers the deformation and forces the connecting rod 234 to rotate and reset.

[0066] It should be noted that the elastic member is a torsion spring, a leaf spring, etc., which and the installation method thereof are all prior arts, and are not drawn in the accompanying drawings, and will not be described in detail here.

[0067] Working process: First, the outer sleeve 11 and the inner sleeve 12 formed by the two forming mechanisms 3 are positioned and transported to the two bearing mechanisms 5 respectively with the help of the discharging mechanism 4. After positioning and carrying, the two bearing mechanisms 5 are moved to position and transport the outer sleeve 11 and the inner sleeve 12 to the two sides of the assembly mechanism 2. Next, the grabbing mechanism 7 grabs the outer sleeves 11 and the inner sleeves 12 in the two bearing mechanisms 5 and positions them on the first support assembly 22 and the second support assembly 23 for positioning and support, and then the mounting assembly 24 installs the bolts 15 in the mounting holes 141 on the outer sleeves 11 and the inner sleeves 12. The grabbing mechanism 7 grabs the rolling assembly 13 that is positioned and transported by the conveying mechanism 6 and positions it in the outer sleeve 11 for installation. Then, after rotating the second support assembly 23 to the position directly above the first support assembly 22, the press 21 presses the inner sleeve 12 to move into the outer sleeve 11, and the outer sleeve 11 and the inner sleeve 12 are squeezed and assembled; Finally, the first support component 22 for positioning the filling hole 113 is able to directly fill grease into the sealing cavity 112, and then after the sealing plug 114 is positioned and installed in the filling hole 113 through the installation component 24, the grasping mechanism 7 is able to grasp the bearing 1 produced on the first support component 22 for unloading.
