Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-strength anti-vibration bearing structure. Background Art

[0002] Bearings are an important component in modern industry, mainly including inner rings, outer rings, cages and rolling elements. Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. When other parts move relative to each other on the shaft, bearings can be used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Therefore, bearings are an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission.

[0003] After searching, the prior art (publication number: CN215214374U) describes a "high-strength, anti-vibration bearing structure comprising a bearing inner ring, the outer circumferential surface of which is provided with a plurality of balls, a retainer fixedly mounted on the outer circumferential surface of the bearing inner ring and on both sides of the balls, a bearing outer ring provided on the outer surface of the plurality of balls, an anti-seismic ring fixedly mounted on the outer circumferential surface of the bearing outer ring, and a plurality of spring balls fixedly mounted evenly between the bearing outer ring and the anti-seismic ring. In the present utility model, the bearing outer ring, anti-seismic ring, spring balls, and I-shaped blocks cooperate to disperse external forces acting on the bearing, thereby improving the bearing's anti-seismic performance. Rotating the rotating rod drives the threaded rod to rotate, thereby separating the L-shaped clamping rod from the retainer, facilitating disassembly of the retainer and thus facilitating maintenance of the bearing."

[0004] Although the high-strength anti-vibration bearing structure in the existing technology has achieved easy disassembly and maintenance of the retaining frame and anti-vibration effect, it still has some shortcomings: the existing anti-vibration bearing lacks the sealing effect of the internal spring ball and ball, resulting in dust, moisture and oil entering, affecting its anti-vibration effect and reducing the use effect of the bearing itself. Secondly, the outer ring of the bearing is generally fixed to the bearing seat to remain stationary, and the inner ring is connected to the drive shaft to remain in operation. Therefore, the elastic balls and I-shaped blocks involved are always at the bottom of the bearing to achieve longitudinal anti-vibration effect. Therefore, metal fatigue will occur over a long period of time, seriously causing component deformation and thus leading to mineral content. Utility Model Content

[0005] In order to overcome the defects of the existing technology, a high-strength anti-vibration bearing structure is now provided to solve the problems of deviation in the sealing effect of the existing anti-vibration bearing on internal components and metal fatigue deformation of the components.

[0006] To achieve the above-mentioned purpose, a high-strength anti-vibration bearing structure is provided, including: a bearing body, the bearing body including an outer ring, and a retaining frame is provided on the inner side of the outer ring, balls are provided inside the retaining frame, and an inner ring is provided inside the balls, a sealing groove and a mounting groove are provided on the inner wall of the outer ring, and a sealing assembly is provided inside the sealing groove, and an anti-vibration assembly is provided inside the mounting groove, the sealing assembly includes a metal sheet on the outside, and a rubber sheet is bonded to the inside of the metal sheet, the anti-vibration assembly includes a steel ball with one end rollingly connected to the mounting groove, and a fixing block with the other end fixedly connected to the inner ring.

[0007] Furthermore, the metal sheet is provided with a fan-shaped structure, the metal sheet and the rubber sheet are connected with equal sizes, and the inner and outer edges of the metal sheet are provided with chamfers.

[0008] Furthermore, an outer end surface of the metal sheet is provided with an outer ear protruding outward, and the outer ear is set to a semicircular structure, and grooves are provided on both sides of the outer ear.

[0009] Furthermore, the anti-seismic assembly also includes a movable block fixedly connected to the steel ball, and the inner end of the movable block is connected to a sliding rod, and an elastic pad is provided at the connection between the movable block and the sliding rod.

[0010] Furthermore, the outer end of the fixed block is connected to a sleeve, a spring is provided inside the sleeve, and the inner end of the sliding rod is slidably inserted into the sleeve.

[0012] Furthermore, the sealing grooves and the mounting grooves are both provided in two groups, and are respectively opened on the inner wall of the outer ring and the outer wall of the inner ring.

[0013] The beneficial effects of the present invention are:

[0014] 1. The metal and rubber sheets included in the sealing assembly are used to seal the cage, balls and anti-vibration components of the bearing body against dust, moisture and oil pollution after installation in the sealing groove, thereby protecting the internal components and extending the service life of the bearing body. At the same time, the chamfers and external ears allow them to be directly removed from the sealing groove using external tools (pliers, etc.) for replacement and maintenance.

[0015] 2. By utilizing the fixed blocks included in the anti-seismic assembly, after the bearing body is fixed, when the inner ring rotates with the central shaft (transmission shaft), the sleeve, slide rod, movable block and steel ball are driven to rotate together, so that the steel ball and the mounting groove on one side of the inner wall of the outer ring move relative to each other, thereby enabling multiple sets of anti-seismic assemblies to all play a longitudinal supporting and anti-seismic effect, and in the vertical direction of the bearing, the anti-seismic effect is achieved through the slide rod, spring and sleeve, thereby reducing the probability of fatigue deformation caused by long-term pressure vibration of a certain anti-seismic component, thereby extending the service life of the anti-seismic assembly.

[0021] Reference Figures 1 to 4 As shown, the utility model provides a high-strength anti-vibration bearing structure, including: a bearing body 1, the bearing body 1 includes an outer ring 2, and a retaining frame 4 is provided on the inner side of the outer ring 2, a ball 3 is provided inside the retaining frame 4, and an inner ring 5 is provided on the inner side of the ball 3, and a sealing groove 21 and a mounting groove 22 are provided on the inner wall of the outer ring 2. There are two groups of sealing grooves 21 and mounting grooves 22, which are respectively provided on the inner wall of the outer ring 2 and the outer wall of the inner ring 5, and a sealing component 7 is provided inside the sealing groove 21, and an anti-vibration component 6 is provided inside the mounting groove 22. The sealing component 7 includes an outer metal sheet 71, and a rubber sheet 72 is bonded to the inner side of the metal sheet 71. The anti-vibration component 6 includes a steel ball 61, one end of which is rollingly connected to the mounting groove 22, and a fixing block 67 fixedly connected to the inner ring 5 at the other end.

[0022] In this embodiment, the outer ring 2 and the inner ring 5 included in the bearing body 1 are both made of carbon structural steel, and the balls 3 are made of titanium alloy, thereby enhancing the strength of the bearing body 1 .

[0023] Specifically, the sealing groove 21 is located outside the mounting groove 22 , and the inner and outer sealing grooves 21 and the mounting groove 22 correspond to each other in radial positions of the bearing body 1 .

[0024] The connection between the outer ring 2, balls 3, cage 4 and inner ring 5 is consistent with the bearing structure in the prior art.

[0025] like Figure 3 and Figure 4 As shown, the metal sheet 71 is provided with a fan-shaped structure, and the metal sheet 71 and the rubber sheet 72 are connected in equal size, and the inner and outer edges of the metal sheet 71 are provided with chamfers 74, and the outer end face of the metal sheet 71 is provided with an outer ear 73 protruding outward, and the outer ear 73 is provided with a semicircular structure, and grooves are provided on both sides of the outer ear 73.

[0026] As a preferred embodiment, the metal sheet 71 is made of elastic steel, and then a chamfer 74 is provided to facilitate installation under certain elastic properties, while the external ear 73 is provided to facilitate clamping and disassembly using external tools.

[0027] like Figure 1 and Figure 4 As shown, the anti-seismic component 6 also includes a movable block 62 fixedly connected to the steel ball 61, and the inner end of the movable block 62 is connected to the slide rod 64, and an elastic pad 63 is provided at the connection between the movable block 62 and the slide rod 64, the outer end of the fixed block 67 is connected to the sleeve 65, and a spring 66 is provided inside the sleeve 65, and the inner end of the slide rod 64 is slidably inserted in the sleeve 65, the outer end of the sleeve 65 is set as an open end, and the inner end is set as a blocking end, and one end of the spring 66 is fixedly connected to the blocking end, and the other end is fixedly connected to the slide rod 64.

[0028] As a preferred embodiment, by setting the sleeve 65, the spring 66 and the slide rod 64, the radial shock absorption effect is achieved in the radial direction of the bearing body 1. At the same time, by setting the elastic pad 63, the elastic anti-collision effect is increased between the movable block 62 and the sleeve 65.

[0029] It should be noted that under normal use, a certain distance is maintained between the movable block 62 and the sleeve 65.

At the same time, the chamfers and external ears allow it to be directly removed from the sealing groove using external tools (pliers, etc.) for replacement and maintenance. The fixing blocks included in the anti-vibration assembly enable, after the bearing body is fixed, when the inner ring rotates with the center shaft (transmission shaft), the sleeve, slide rod, movable block and steel ball are driven to rotate together, causing the steel ball to move relative to the mounting groove on the inner wall side of the outer ring, thereby enabling multiple sets of anti-vibration assemblies to all play a longitudinal supporting and anti-vibration effect. In the vertical direction of the bearing, the slide rod, spring and sleeve achieve an anti-vibration effect, thereby reducing the probability of fatigue deformation caused by long-term pressure vibration of a certain anti-vibration component, thereby extending the service life of the anti-vibration assembly.

[0031] The high-strength anti-vibration bearing structure of the utility model can effectively solve the problem of deviation in the sealing effect of existing anti-vibration bearings on internal components, and the problem of metal fatigue deformation of components. It achieves the improvement of the sealing effect of existing anti-vibration bearings on components on the basis of existing high-strength anti-vibration bearing structure technology, and reduces the probability of metal fatigue and deformation of anti-vibration bearings, thereby extending the service life.
