Description

Technical Field

[0001] This utility model relates to the field of bearings, and in particular to a dustproof bearing. Background Technology

[0002] A bearing is a mechanical component primarily used to support and guide rotating or linearly moving mechanical parts, reducing friction and wear during operation. It achieves smooth movement of parts by incorporating rolling elements (such as balls, rollers, or sliding surfaces) between inner and outer rings, thereby significantly reducing friction between rotating components and making mechanical operation smoother.

[0003] The prior art (publication number: CN222991949U) discloses that "this utility model provides a dustproof bearing, relating to the field of bearing dustproof technology, including: a bearing body, wherein four connecting grooves are provided on the bottom side of the bearing body. This utility model connects the bearing body with the components between the grooves and the first and second dustproof plates by interlocking. During installation, the first dustproof plate is rotated in a guided interlocking and sliding manner by the anti-detachment block connected to the first dustproof plate, so that the anti-detachment groove of the connecting block can interlock with the anti-detachment block. In the interlocking state, the groove of the first dustproof plate will be in communication with the threaded sleeve connected to the connecting block and the through groove of the bearing body, eliminating the need for workers to align the holes one by one, thus saving the positioning steps during installation. The guided connection method facilitates disassembly and assembly operations for users."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: the device requires frequent manual addition of lubricating oil, which increases the workload and cost of maintenance. Moreover, manual addition of lubricating oil can easily lead to uneven or insufficient lubrication, affecting the lubrication effect and service life of the bearing.

[0005] Therefore, those skilled in the art have provided a dustproof bearing to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dustproof bearing in which lubricating oil is stored in an oil reservoir. During the rotation of the balls, the lubricating oil can slowly seep out through the oil seepage holes to the space between the outer and inner rings, thereby achieving lubrication and reducing friction and wear.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A dustproof bearing includes an outer ring, a top cover, a bottom cover, multiple balls, and an inner ring. The upper end of the outer ring has four oil inlets, the inner wall of the outer ring has four oil storage grooves, and the inner end of the outer ring has multiple oil leakage holes.

[0009] The lower end of the outer ring is threaded with a No. 1 bolt, and the upper end of the outer ring is threaded with a No. 2 bolt.

[0010] Furthermore, multiple balls are disposed between the inner end of the outer ring and the outer end of the inner ring, and the four oil inlets are connected to the four oil reservoirs.

[0011] Furthermore, the plurality of oil seepage holes are connected to four oil storage tanks, and the bottom cover is fixedly installed at the lower end of the outer ring by bolt No. 1.

[0012] Furthermore, the thread of the second bolt is located inside the first bolt, and the top cover is fixedly mounted on the upper end of the outer ring by the second bolt.

[0013] Furthermore, the outer ring includes a connecting layer, a buffer layer is provided at the inner end of the connecting layer, and a wear-resistant layer is provided at the inner end of the buffer layer.

[0014] Furthermore, the connecting layer is made of austenitic stainless steel, and the buffer layer is made of low alloy steel.

[0015] Furthermore, the wear-resistant layer is made of carburized steel.

When installing the device, first align the hole of the bottom cover with the threaded hole at the lower end of the outer ring, then screw in the No. 1 bolt. Next, place the balls inside the outer ring and on the top of the bottom cover, then install the inner ring. At this time, lubricating oil can be added to the oil inlet. The lubricating oil is stored in the oil reservoir. During the rotation of the balls, the lubricating oil can slowly seep out through the oil seepage holes between the outer and inner rings, thereby achieving lubrication, reducing friction and wear, and extending the service life of the bearing. Finally, place the top cover on top of the outer and inner rings, and then screw in the No. 2 bolt into the threaded hole of the outer ring.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5 One embodiment provided by this utility model:

[0029] A dustproof bearing includes an outer ring 1, a top cover 5, a bottom cover 6, multiple balls 7, and an inner ring 8. The upper end of the outer ring 1 has four oil inlets 2, the inner wall of the outer ring 1 has four oil reservoirs 3, and the inner end of the outer ring 1 has multiple oil leakage holes 4. The lower end of the outer ring 1 is threaded with a No. 1 bolt 9, and the upper end of the outer ring 1 is threaded with a No. 2 bolt 10. The multiple balls 7 are disposed between the inner end of the outer ring 1 and the outer end of the inner ring 8. The four oil inlets 2 are connected to the four oil reservoirs 3, and the multiple oil leakage holes 4 are connected to the four oil reservoirs 3. The bottom cover 6 is fixedly disposed at the lower end of the outer ring 1 by the No. 1 bolt 9, and the No. 2 bolt 10 is threaded on the inner end of the No. 1 bolt 9. The top cover 5 is fixedly disposed at the upper end of the outer ring 1 by the No. 2 bolt 10.

[0030] Specifically, when installing this device, first align the hole of the bottom cover 6 with the threaded hole at the lower end of the outer ring 1, then screw in the No. 1 bolt 9, then place the ball 7 inside the outer ring 1 and the top of the bottom cover 6, then install the inner ring 8, then place the top cover 5 on the top of the outer ring 1 and the inner ring 8, and then screw in the No. 2 bolt 10 into the threaded hole of the outer ring 1.

[0031] Since the No. 1 bolt 9 also has a threaded hole, the No. 2 bolt 10 can be screwed into the No. 1 bolt 9. Before the No. 1 bolt 9 is screwed out, the No. 1 bolt 9 cannot be screwed out. At this time, the top cover 5 and the bottom cover 6 can play a dustproof role.

[0032] Before screwing in the No. 2 bolt 10, lubricating oil can be added to the oil inlet 2. The lubricating oil will be stored in the oil reservoir 3. During the rotation of the ball 7, the lubricating oil can seep out from the oil seepage hole 4 between the outer ring 1 and the inner ring 8, thereby lubricating the ball 7.

[0033] Reference Figure 6 The outer ring 1 includes a connecting layer 101, a buffer layer 102 is provided at the inner end of the connecting layer 101, and a wear-resistant layer 103 is provided at the inner end of the buffer layer 102. The connecting layer 101 is made of austenitic stainless steel, the buffer layer 102 is made of low alloy steel, and the wear-resistant layer 103 is made of carburized steel.

[0034] Specifically, the outermost connecting layer 101 of the outer ring 1 is made of austenitic stainless steel, which not only has excellent corrosion resistance but also provides high structural strength, adapts to various harsh environments, and ensures the long-term reliability of the dustproof bearing.

[0035] The buffer layer 102 is made of low alloy steel, which has good toughness and buffering capacity, can alleviate external impact and vibration, protect the bearing structure, and improve the overall running stability.

[0036] The wear-resistant layer 103 is made of carburized steel, which has excellent hardness and wear resistance, and can resist long-term friction and wear, reducing the frequency of replacement.

[0037] The connecting layer 101, the buffer layer 102 and the wear-resistant layer 103 are connected by high-temperature brazing, which can realize the metallurgical bonding of the three-layer materials, provide high strength and seamless connection, and effectively prevent the separation or cracking between the layers.

[0038] Working principle: When installing this device, first align the hole of the bottom cover 6 with the threaded hole at the lower end of the outer ring 1, then screw in the No. 1 bolt 9, then place the ball 7 into the outer ring 1 and the top of the bottom cover 6, and then install the inner ring 8. At this time, lubricating oil can be added to the oil inlet 2. The lubricating oil is stored in the oil reservoir 3. During the rotation of the ball 7, the lubricating oil can slowly seep out through the oil seepage hole 4 between the outer ring 1 and the inner ring 8. Finally, place the top cover 5 on the top of the outer ring 1 and the inner ring 8, and then screw in the No. 2 bolt 10 into the threaded hole of the outer ring 1.

[0039] Secondly, the outermost connecting layer 101 of the outer ring 1 is made of austenitic stainless steel, which has excellent corrosion resistance. The buffer layer 102 is made of low alloy steel, which has good toughness and buffering capacity. The wear-resistant layer 103 is made of carburized steel, which has excellent hardness and wear resistance.
