Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and specifically relates to an anti-corrosion bearing. Background Art

[0002] Bearings are a common and key component in various mechanical equipment and industrial applications. Their main function is to support and guide the movement of the rotating shaft, while reducing friction and wear to ensure the normal operation of the equipment. Existing bearings include an outer ring, a sealing cover, an inner ring, a cage and balls. A cage is set between the outer ring and the inner ring, and the cage is set with balls, while the sealing cover is set on the outer ring by bolts for sealing.

[0003] However, in some harsh working environments, such as places with humid and corrosive media, bearings are easily affected by corrosion, which reduces their service life and performance.

[0004] At present, some designs and technologies for anti-corrosion bearings have been proposed. For example, special materials such as stainless steel and ceramics are used to manufacture bearings to improve their corrosion resistance. In addition, coating treatments such as electroplating and spraying on the bearing surface can also enhance its corrosion resistance. However, these methods still have some limitations. For example, the cost of special materials is high, and the coating may peel off or wear during use, thus affecting the anti-corrosion effect.

[0005] Secondly, when the bearing is working, it will generate vibration. Long-term vibration will cause the bolts on the sealing cover to loosen, resulting in the poor effect of the sealing cover, so that external water vapor and dust can enter the interior of the bearing body, causing corrosion.

[0006] To this end, we proposed an anti-corrosion bearing. This bearing is not only innovative in structure, but also combines magnetic principles and elastic components to improve the lubrication effect and the stability of bolt fixing, further enhancing the anti-corrosion performance of the bearing. By opening a tapered groove and setting a magnetic plate, automatic grease supply is achieved, reducing friction and wear. At the same time, the design of the elastic component and the limit rod effectively solves the problem of bolt loosening and improves the sealing effect of the sealing cover. Utility Model Content

[0007] The purpose of this utility model is to provide an anti-corrosion bearing, which combines the magnetic principle and the elastic component to improve the lubrication effect and the stability of the bolt fixing, further enhances the anti-corrosion performance of the bearing, and realizes the automatic supply of grease by opening a tapered groove and setting a magnetic plate, thereby reducing friction and wear. At the same time, the design of the elastic component and the limit rod effectively solves the problem of bolt loosening and improves the sealing effect of the sealing cover.

[0008] The technical solutions adopted in this utility are as follows:

[0009] An anti-corrosion bearing comprises a bearing body, wherein the bearing body comprises an outer ring, a sealing cover, an inner ring, a retainer and balls, wherein the retainer is arranged between the outer ring and the inner ring, and the balls are arranged on the retainer;

[0010] The outer ring is provided with a conical groove, grease and a conical plate are arranged inside the conical groove, the grease is arranged on the top of the conical plate, and the first magnetic surface is arranged at the bottom of the conical plate. The retaining frame is composed of eight ball bearing shells and eight connecting plates, one connecting plate is arranged between every two ball bearing shells, and a first connecting rod is arranged on the top of each connecting plate, a first fixing plate is arranged on the top of the first connecting rod, and a second magnetic surface that repels the first magnetic surface is arranged on the first fixing plate;

[0011] The sealing cover is mounted on the outer ring by bolts, a rotating disk is arranged on the bolts, a plurality of limiting grooves are provided on the rotating disk, a plurality of L-shaped frames are arranged on the outer side of the outer ring, a first sliding groove is provided on the L-shaped frame, an elastic component is arranged inside the first sliding groove, and a limiting rod inserted into the limiting groove is arranged on the elastic component.

[0012] Furthermore, an anti-corrosion layer is provided on the ball.

[0013] Furthermore, a sealing plate is provided on the conical groove.

[0014] Furthermore, the limiting rod matches the limiting groove.

[0015] Furthermore, the elastic component includes a fixed shaft arranged inside the first slide groove, a slider and a spring are sleeved on the fixed shaft, the springs are arranged on both sides of the slider, and one side of the slider is connected to the limit rod.

[0016] Furthermore, the first sliding groove matches the sliding block.

[0017] The technical effects achieved by this utility model are:

[0018] First, the inner ring is driven by the rotation of the external rotating shaft, so that the retaining frame drives the ball to rotate on the inner wall of the outer ring, thereby working. When the retaining frame drives the ball to rotate, the connecting plate drives the first connecting rod to rotate the first fixed plate. When the first fixed plate rotates to the position corresponding to the tapered groove, the second magnetic surface and the first magnetic surface generate repulsion, thereby opening the flow gap between the tapered plate and the tapered groove, so that the grease flows through the flow gap, so when the ball arrives, it will fall on the ball for lubrication, thereby reducing friction and preventing the anti-corrosion layer on the ball from wearing, thereby improving its anti-corrosion effect. At the same time, vibration will be generated when the bearing is working. Long-term vibration will cause the bolts on the sealing cover to loosen, resulting in the deterioration of the effect of the sealing cover, thereby allowing external water vapor and dust to enter the inside of the bearing body, causing corrosion. For this reason, when the sealing cover is installed on the outer ring through bolts, the limit rod is inserted into the limit groove on the sealing cover through the action of the elastic component, thereby effectively improving the effect of bolt fixing, further improving the sealing effect of the sealing cover, and thus improving the anti-corrosion effect of the bearing body.

DETAILED DESCRIPTION

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0027] like Figure 1-5 As shown, the technical solution adopted by the utility model is as follows: an anti-corrosion bearing comprises a bearing body 1, the bearing body 1 comprises an outer ring 2, a sealing cover 3, an inner ring 4, a retainer 5 and a ball 6, a retainer 5 is arranged between the outer ring 2 and the inner ring 4, and the retainer 5 is arranged on the ball 6;

[0028] The outer ring 2 is provided with a conical groove 7, grease and a conical plate 8 are arranged inside the conical groove 7, grease is arranged on the top of the conical plate 8, and a first magnetic surface is arranged at the bottom of the conical plate 8. The retainer 5 is composed of eight ball bearing shells 9 and eight connecting plates 10. A connecting plate 10 is arranged between every two ball bearing shells 9, and a first connecting rod is arranged on the top of each connecting plate 10. A first fixing plate 11 is arranged on the top of the first connecting rod, and a second magnetic surface that repels the first magnetic surface is arranged on the first fixing plate 11;

[0029] The sealing cover 3 is mounted on the outer ring 2 by bolts, a rotating disk 12 is arranged on the bolts, a plurality of limiting grooves 13 are provided on the rotating disk 12, a plurality of L-shaped frames 14 are arranged on the outer side of the outer ring 2, a first slide groove 15 is provided on the L-shaped frame 14, an elastic component is arranged inside the first slide groove 15, and a limiting rod 20 inserted into the limiting groove 13 is arranged on the elastic component.

[0030] Its working principle is as follows: first, the inner ring 4 is driven to rotate by the external rotating shaft, so that the retaining frame 5 drives the ball 6 to rotate on the inner wall of the outer ring 2, thereby working. When the retaining frame 5 drives the ball 6 to rotate, the connecting plate 10 drives the first connecting rod to rotate the first fixed plate 11. When the first fixed plate 11 rotates to the position corresponding to the tapered groove 7, the second magnetic surface and the first magnetic surface generate repulsive force, so that the flow gap between the tapered plate 8 and the tapered groove 7 is opened, so that the grease flows through the flow gap, so when the ball 6 arrives, it will fall on the ball 6 for lubrication, thereby reducing friction and preventing The anti-corrosion layer on the ball 6 is worn, thereby improving its anti-corrosion effect. At the same time, vibration will be generated when the bearing is working. Long-term vibration will cause the bolts on the sealing cover 3 to loosen, resulting in a deterioration in the effect of the sealing cover 3, thereby allowing external water vapor and dust to enter the interior of the bearing body 1, causing corrosion. For this reason, when the sealing cover 3 is installed on the outer ring 2 by bolts, the limit rod 20 is inserted into the limit groove 13 on the sealing cover 3 through the action of the elastic component, thereby effectively improving the bolt fixing effect, further improving the sealing effect of the sealing cover 3, and thus improving the anti-corrosion effect of the bearing body 1.

[0031] Furthermore, an anti-corrosion layer is provided on the ball 6, and the anti-corrosion performance of the ball 6 can be improved by the anti-corrosion layer.

[0032] The conical groove 7 matches the conical plate 8, which means that the conical plate 8 can move smoothly inside the conical groove 7 without getting stuck.

[0033] At the same time, a sealing plate 17 is provided on the conical groove 7, and the connection method here is bolt connection, so that the conical groove 7 can be sealed to prevent grease leakage.

[0034] It should be noted that: the utility model prefers grease, because if lubricating liquid is used when the bearing rotates, it will cause the lubricating liquid to flow out quickly, resulting in the lubricating liquid being gone after a period of use, and it cannot be used for a long time. If grease is used, the grease will flow out from the inside of the tapered groove 7 when the second magnetic surface and the first magnetic surface generate repulsion. At the same time, the flow is very slow, and it takes many times for the second magnetic surface to repel the first magnetic surface before it can drip on the ball 6. This increases the lubrication time. Even if the grease drips on other positions, due to the action of centrifugal force and the rotation of the ball 6, the grease will be spread on the rotating track of the ball 6 due to these actions, thereby reducing friction and protecting the anti-corrosion layer on the ball 6 from damage due to friction.

[0035] The limiting rod 20 matches the limiting groove 13 , and matching here means that the diameter of the limiting rod 20 matches the aperture of the limiting groove 13 , so that the limiting rod 20 can be inserted into the limiting groove 13 for limiting.

[0036] The utility model has four limiting grooves 13, and can also have more than one, depending on the designer's design.

[0037] The elastic component includes a fixed shaft 16 arranged inside the first sliding groove 15 , a slider 19 and a spring 18 are sleeved on the fixed shaft 16 , springs 18 are arranged on both sides of the slider 19 , and one side of the slider 19 is connected to the limit rod 20 .

[0038] When the sealing cover 3 is limited, the slider 19 drives the limiting rod 20 to enter the limiting groove 13 for fixing by the elastic force of the spring 18 .

[0039] The first slide groove 15 matches with the slider 19 , and matching here means that the slider 19 can move smoothly inside the first slide groove 15 without getting stuck.

[0040] The working principle of the utility model is as follows: firstly, the inner ring 4 is driven to rotate by the external rotating shaft, so that the retaining frame 5 drives the ball 6 to rotate on the inner wall of the outer ring 2, thereby working; when the retaining frame 5 drives the ball 6 to rotate, the connecting plate 10 drives the first connecting rod to rotate the first fixing plate 11; when the first fixing plate 11 rotates to the position corresponding to the conical groove 7, the second magnetic surface and the first magnetic surface generate a repulsive force, so that the flow gap between the conical plate 8 and the conical groove 7 is opened, so that the grease flows through the flow gap, so that when the ball 6 arrives, it will fall on the ball 6 for lubrication, thereby reducing the friction. , preventing the anti-corrosion layer on the ball 6 from wearing, thereby improving its anti-corrosion effect. At the same time, vibration will be generated when the bearing is working. Long-term vibration will cause the bolts on the sealing cover 3 to loosen, resulting in the deterioration of the effect of the sealing cover 3, thereby allowing external water vapor and dust to enter the interior of the bearing body 1, causing corrosion. For this reason, when the sealing cover 3 is installed on the outer ring 2 by bolts, the limit rod 20 is inserted into the limit groove 13 on the sealing cover 3 through the action of the elastic component, thereby effectively improving the bolt fixing effect, further improving the sealing effect of the sealing cover 3, and thus improving the anti-corrosion effect of the bearing body 1.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
