Description

Technical Field

[0001] The utility model relates to the technical field of bearing sealing, in particular to a wear-resistant sealing bearing structure. Background Art

[0002] A bearing is a mechanical element that can withstand and reduce friction between moving parts in mechanical equipment. It is widely used in various mechanical equipment, from automobiles to industrial machines to household appliances. The main function of a bearing is to support rotating shafts and other moving parts so that they can run smoothly with less friction, thereby improving the efficiency and life of the equipment.

[0003] The bearing is composed of an inner ring, an outer ring, and rolling elements. The balls or rollers in traditional bearings are often exposed to the outside, and there is no relative sealing structure. As a result, the balls or rollers in the bearings are easily invaded by external pollutants such as dust, dirt, and moisture, which causes increased internal wear of the bearing and affects its life and performance. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a wear-resistant sealed bearing structure, which aims to improve the problem that the balls or rollers in the traditional bearings in the prior art are often exposed to the outside and no relative sealing structure is set, resulting in the balls or rollers in the bearings being easily invaded by external pollutants such as dust, dirt, and moisture.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wear-resistant sealed bearing structure comprises an inner ring, a retaining frame is arranged outside the inner ring, balls are rotatably connected inside the retaining frame, an outer ring is arranged outside the balls, sealing gaskets are arranged in the middle of the outer ring and the inner ring, blocks are fixedly connected on both sides of the inner ring, and bumps are fixedly connected on both sides of the outer ring.

[0007] Furthermore, a wear-resistant layer is arranged inside the outer ring, a base layer is arranged outside the wear-resistant layer, and a reinforcement layer is arranged outside the base layer.

[0008] Furthermore, both sides of the sealing gasket are provided with card slots, and the two card blocks are engaged with the two card slots.

[0009] Furthermore, both sides of the inner part of the outer ring are provided with insertion holes, and the two protrusions are plugged into the two insertion holes.

[0010] Furthermore, the material of the base layer is high-carbon chromium steel, and the material of the reinforcement layer is high-strength carbon fiber material.

[0011] Furthermore, the sealing gasket is made of nitrile rubber.

[0012] Furthermore, the wear-resistant layer is made of hardened steel.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, during the installation process, the groove of the sealing gasket is engaged with the block on the outer ring, and the protrusion is inserted into the socket of the outer ring, so that the sealing gasket is firmly installed, and the installation operation of the sealing gasket is convenient. By installing the sealing gasket, external pollutants (such as dust, dirt and moisture) are prevented from entering the interior of the bearing, corrosion and wear of the rolling elements and raceways are avoided, and the service life of the bearing is increased.

[0015] 2. In the utility model, the base layer made of high-carbon chromium steel allows the bearing to maintain a good working condition under high load and high speed. The reinforcement layer made of high-strength carbon fiber material enables the bearing to withstand greater loads and impacts and adapt to harsh working conditions. The wear-resistant layer made of hardened steel effectively resists the wear of rolling elements and contact surfaces, prolongs the life of the bearing, and effectively reduces the wear between the various parts of the bearing through the coordination of the base layer, reinforcement layer and wear-resistant layer, greatly improving the service life.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2The utility model provides an embodiment: a wear-resistant sealed bearing structure, including an inner ring 3, a retaining frame 8 is arranged outside the inner ring 3, balls 9 are rotatably connected inside the retaining frame 8, an outer ring 1 is arranged outside the ball 9, a sealing gasket 2 is arranged in the middle of the outer ring 1 and the inner ring 3, blocks 4 are fixedly connected on both sides of the inner part of the outer ring 1, protrusions 6 are fixedly connected on both sides of the outer part of the sealing gasket 2, a wear-resistant layer 12 is arranged inside the outer ring 1, a base layer 11 is arranged outside the wear-resistant layer 12, a reinforcement layer 10 is arranged outside the base layer 11, slots 5 are opened on both sides of the inner part of the sealing gasket 2, two blocks 4 are engaged with the two slots 5, and sockets 7 are opened on both sides of the inner part of the outer ring 1, and two protrusions 6 are plugged into the two sockets 7.

[0023] During the installation process, the groove 5 of the sealing gasket 2 is engaged with the block 4 on the outer ring 1, and the protrusion 6 is inserted into the socket 7 inside the outer ring 1, so that the sealing gasket 2 is firmly installed. If the sealing gasket 2 and the wear-resistant layer 12 are worn during long-term use, they can be replaced by disassembling the outer ring 1, releasing the engagement between the block 4 and the groove 5, and the connection between the protrusion 6 and the socket 7, thereby facilitating the installation operation of the sealing gasket 2. By installing the sealing gasket 2, external contaminants (such as dust, dirt and moisture) are prevented from entering the interior of the bearing, corrosion and wear of the rolling elements and raceways are avoided, and the service life of the bearing is increased.

[0024] Reference Figure 3 The material of the base layer 11 is high carbon chromium steel, the material of the reinforcement layer 10 is high strength carbon fiber material, the material of the sealing gasket 2 is nitrile rubber, and the material of the wear-resistant layer 12 is hardened steel.

[0025] By using high carbon chromium steel as the material of the base layer 11, the high carbon chromium steel has a very high hardness after heat treatment such as quenching and tempering, which enables the base layer 11 to effectively resist wear and fatigue, ensuring that the bearing maintains a stable working state under high load and high speed. The reinforcing layer 10 is made of high-strength carbon fiber material, which has extremely high strength and rigidity, and significantly enhances the overall structural strength of the bearing, enabling it to withstand greater loads and impact forces and adapt to more severe working conditions. The sealing gasket 2 is made of nitrile rubber, which has good elasticity and compression recovery, and can effectively seal to prevent contaminants from entering. The wear-resistant layer 12 is made of hardened steel, which can maintain its mechanical properties in a high temperature environment and is suitable for high temperature working conditions.

[0026] Working principle: During the installation process, the groove 5 of the sealing gasket 2 is engaged with the block 4 on the outer ring 1, and the protrusion 6 is inserted into the socket 7 inside the outer ring 1 to achieve a stable installation of the sealing gasket 2. When the bearing is running, the ball 9 rolls between the inner ring 3 and the outer ring 1 under the guidance of the retaining frame 8. The wear-resistant layer 12 reduces the friction between the ball 9 and the outer ring 1, thereby extending the service life of the bearing. If the sealing gasket 2 and the wear-resistant layer 12 are worn, they can be replaced by disassembling the outer ring 1, releasing the engagement between the block 4 and the groove 5, and releasing the connection between the protrusion 6 and the socket 7, thereby facilitating the installation of the sealing gasket 2. By installing the sealing gasket 2, external pollutants (such as dust, dirt and moisture) are prevented from entering the shaft. The inside of the bearing is protected from corrosion and wear of the rolling elements and raceways, thereby increasing the service life of the bearing. The material of the base layer 11 is high-carbon chromium steel, so that the bearing can maintain a good working condition under high load and high speed. The material of the reinforcement layer 10 is high-strength carbon fiber material. This high-strength performance enables the bearing to withstand greater loads and impact forces and adapt to more severe working conditions. The material of the wear-resistant layer 12 is hardened steel, which can effectively resist the wear of the rolling elements and other contact surfaces and extend the service life of the bearing. The cooperation of the base layer 11, the reinforcement layer 10 and the wear-resistant layer 12 can effectively reduce the wear between the parts in the bearing, thereby greatly increasing the service life.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
