[0007] Optionally, it further comprises: a porous bronze sleeve, wherein the porous bronze sleeve is embedded on the raceway outer ring of the angular contact ball bearing, and a cavity is provided in the porous bronze sleeve.

[0008] Optionally, the cavity is filled with lubricating oil.

[0009] Optionally, it also includes: a protective plate, wherein the protective plate is embedded in the angular contact ball bearing.

[0010] Optionally, it also includes: a metal ring, wherein the metal ring is embedded in the mounting hole.

[0011] Optionally, it also includes: an anti-wear sleeve, which is installed on the inner ring of the shaft ring.

[0012] Optionally, it also includes: the outer ring of the bearing body is provided with a plurality of mounting holes along the circumferential direction.

[0013] Compared with the prior art, the utility model has the following technical effects: 1. The device adds a shaft ring to support the middle section of the rotating shaft, reducing the mechanical load friction coefficient of the equipment during the transmission process, thereby enhancing the axial load capacity of the angular contact ball bearing.

[0014] 2. By setting the porous bronze sleeve, the lubricating oil can be added at any time when the angular contact ball bearing is working, thereby reducing the friction between the angular contact ball bearing and the rotating shaft and reducing wear. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-Figure 4, a seat bearing comprises: a bearing body 1, a hole retaining ring 2, an angular contact ball bearing 3, a ball 4, a shaft ring 5, a protective plate 7, a metal ring 8 and an anti-wear sleeve 9. The outer ring of the bearing body 1 is provided with three mounting holes 101 along the circumferential direction. The metal ring 8 is embedded in the mounting hole 101. When the bearing body 1 is locked with bolts, the internal gap of the mounting hole 101 can be filled by the metal ring 8 to improve the stability of the installation. Retaining ring holes 201 are provided at the left and right ends of the bearing body 1. The hole retaining ring 2 is embedded in the retaining ring hole 201. Angular contact ball bearings 3 are installed at the left and right ends of the bearing body 1. The ball 4 is filled in the raceway outer ring and the angular contact ball bearing 3. Between the inner rings, the angular contact ball bearing 3 is used to replace the deep groove ball bearing. Since the contact angle between the inner and outer rings of the angular contact ball bearing 3 and the ball 4 is relatively small, it can share a larger load, thereby bearing a larger radial load and axial load. The protective plate 7 is embedded in the angular contact ball bearing 3. The protective plate 7 can be used to shield and protect the raceway ring of the angular contact ball bearing 3 to prevent foreign matter from getting stuck in the angular contact ball bearing 3 and affecting its operation. The shaft ring 5 is installed between the two angular contact ball bearings 3 to support the mechanical rotating body. The anti-wear sleeve 9 is installed on the inner ring of the shaft ring 5. The anti-wear sleeve 9 is set to reduce the friction between the shaft ring 5 and the rotating shaft.

[0024] The assembly process is as follows

[0025] Step 1: First, apply glue to the bearing hole at one end of the bearing body 1, then knock the angular contact ball bearing 3 into the bearing hole, and then clamp the hole into the retaining ring hole 201 with the retaining ring 2.

[0026] Step 2: Place the bearing body 1 flat on the table, insert the shaft ring 5 into the body, and align the hole position. Finally, repeat step 1 to install another angular contact ball bearing 3 and the hole retaining ring 2 into the other end of the bearing body 1.

[0027] When in use, first install the bearing seat on the machine platform, screw the bolt into the mounting hole 101 to lock it, and then install the shaft. When the bearing seat is working, the middle section of the shaft is supported by the shaft ring 5 to reduce the mechanical load friction coefficient of the equipment during the transmission process, thereby enhancing the axial load capacity of the angular contact ball bearing 3.

[0028] Example 2

[0029] Based on Example 1, please refer to Figure 4 and Figure 5, further comprising: a porous bronze sleeve 6, wherein the porous bronze sleeve 6 is embedded on the raceway outer ring of the angular contact ball bearing 3, wherein a cavity 601 is arranged inside the porous bronze sleeve 6, wherein the cavity 601 is filled with lubricating oil, and when the angular contact ball bearing 3 rotates at a high speed, the rolling friction of the ball 4 is utilized to make the lubricating oil inside the porous bronze sleeve 6 flow out, and a lubricating layer is formed on the surface of the angular contact ball bearing 3, thereby providing good lubrication for the angular contact ball bearing 3, reducing the friction between the angular contact ball bearing 3 and the rotating shaft, and reducing wear.

[0030] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
