DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-3The utility model provides a technical solution: a long-life high-strength bearing structure, comprising an outer ring body 1, the inner side of the outer ring body 1 is movably connected with the inner ring body 2, a driving cavity 3 for rotation is formed between the inner side of the outer ring body 1 and the outer side of the inner ring body 2, a stroke component 400 for allowing the bearing to work is installed on the inner side of the driving cavity 3, and a protective component 500 for protective effect is installed on the inner side of the driving cavity 3; through the coordinated use of the outer ring body 1, the inner ring body 2, the driving cavity 3, the stroke component 400 and the protective component 500, effective protection can be carried out and the protective structure can be conveniently disassembled, so that the service life and strength of the bearing structure can be extended while deep inspection and maintenance can be conveniently carried out, so that the bearing can be used stably for a long time, and in the long run, the user's use cost is saved, thereby greatly improving the practicality of the bearing.

[0024] In this embodiment, the protection component 500 is a structure used to protect the internal structure and thus increase the service life.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the protection assembly 500 includes two protection rings 501 movably connected to the inner side of the outer ring body 1, and two placement rings 502 are fixedly connected to the inner side of the outer ring body 1. The two protection rings 501 are provided with placement grooves 503 for the corresponding placement rings 502 to be inserted on the opposite sides. The left and right sides of the protection rings 501 are provided with installation grooves 504. The inner side of the installation groove 504 is fixedly connected with an elastic member 505. One side of the elastic member 505 is fixedly connected with a sliding block 506. The opposite sides of the sliding blocks 506 are fixedly connected to the limit blocks 507, and the inner side of the outer ring body 1 is provided with four limit grooves 508 for the four limit blocks 507 to be inserted respectively. The opposite sides of the two protective rings 501 are provided with two connecting holes 509, and the inner sides of the connecting holes 509 are fixedly connected to the positioning rods 510, and the opposite sides of the top and bottom sliding blocks 506 are fixedly connected to the positioning blocks 511, and the opposite sides of the left and right positioning blocks 511 are fixedly connected to the bending blocks 512.

[0026] It should be noted that the inner side of the protective ring 501 does not fit the outer side of the inner ring body 2, so that the inner ring body 2 can rotate smoothly. The outer side of the placement groove 503 is open, so that the placement ring 502 can be inserted into the inner side of the placement groove 503, thereby playing a role in lateral limitation of the protective ring 501.

[0027] In addition, the opposite sides of the top and bottom limit blocks 507 are both inclined surfaces, which facilitate the limit blocks 507 to enter the interior of the driving chamber 3 from the outside. The left end of the positioning rod 510 passes through the corresponding positioning block 511, and the interior of the connecting hole 509 is connected to the interior of the corresponding mounting groove 504, so that the positioning block 511 can slide stably on the outside of the corresponding positioning rod 510.

[0028] In this embodiment, the stroke assembly 400 is a structure used to allow the bearing to move normally.

[0029] like Figure 1 and Figure 3 As shown, the stroke assembly 400 includes a ball body 401 that is slidably connected to the inner side of the driving cavity 3 and is evenly distributed, the inner side of the outer ring body 1 is provided with evenly distributed connecting grooves 402, the top of the outer ring body 1 is provided with evenly distributed heat dissipation holes 403, and the top of the protective ring 501 is provided with four evenly distributed oil filling holes 404.

[0030] It should be noted that the cross-section of the inner side of the outer ring body 1 and the cross-section of the outer side of the inner ring body 2 are both trapezoidal, and the inclined surface on the inner side of the outer ring body 1 and the inclined surface on the outer side of the inner ring body 2 are both tangent to the outer side of the ball body 401. The inner side of the outer ring body 1 and the side parallel to the outer side of the inner ring body 2 are not in contact with the outer side of the ball body 401, so that the ball body 401 can roll and rotate under the action of the inclined edge, reducing the contact area, thereby reducing the friction, allowing the ball body 401 to move smoothly.

[0031] In addition, the number of heat dissipation holes 403 is equal to the number of connecting grooves 402, and the interior of the heat dissipation hole 403 is connected with the interior of the corresponding connecting groove 402, so that the heat energy generated by the movement of the ball body 401 can be discharged to the outside through the connecting groove 402 and the interior of the heat dissipation hole 403, thereby reducing the workload of the bearing, enabling it to adapt to more severe working environments, and indirectly improving the actual strength of the bearing. The interior of the oil filling hole 404 can be plugged with a rubber plug to provide sealing performance.

[0032] The working principle of the above embodiment is:

[0033] When disassembly maintenance is required, the two corresponding bending blocks 512 are pushed toward the side close to each other, so that the positioning block 511 drives the sliding block 506 to slide on the inner side of the installation groove 504, the elastic member 505 is compressed, and the limiting block 507 is disengaged from the inner side of the corresponding limiting groove 508, so that the gap between the bending block 512 and the corresponding positioning block 511 is buckled and moved toward the side away from the outer ring body 1, so that the protective ring 501 is moved out from the inside of the driving cavity 3, and the inside of the driving cavity 3 can be repaired. The ball body 401 is deep maintained or lubricated. After the maintenance is completed, the reverse operation is performed according to the above principle. The protective ring 501 is moved to the inside of the driving cavity 3 and pressed downward, so that the limit block 507 is squeezed by the top of the outer ring body 1 and enters the inner side of the installation groove 504, and drives the elastic member 505 to be compressed. Under the elastic force recovery action of the elastic member 505, the limit block 507 is pushed by the sliding block 506 to be inserted into the inner side of the limit groove 508, thereby realizing the effect of card connection and limit, and the normal use can continue.

[0034] Compared with the prior art, the long-life high-strength bearing structure, through the coordinated use of the outer ring body 1, the inner ring body 2, the drive cavity 3, the stroke assembly 400 and the protection assembly 500, can provide effective protection while facilitating the disassembly of the protection structure, thereby extending the service life and strength of the bearing structure while facilitating in-depth inspection and maintenance, so that the bearing can be used stably for a long time, saving the user's use cost in the long run, thereby greatly improving the practicality of the bearing and solving the problem that the existing high-strength and long-life automotive bearings have the functions of long life and high strength but it is inconvenient to disassemble the protection structure.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
