Description

Technical Field

[0001] This utility model relates to the technical field of bearings, and in particular to a high load-bearing deep groove ball bearing. Background Technology

[0002] In the process of use, deep groove ball bearings mainly transmit force through the steel balls between the inner and outer rings. Therefore, the steel balls wear out severely during long-term use. For example, patent application number CN201720107502.3 discloses a high load-bearing deep groove ball bearing and its cage. This patent increases the space between the two corrugated cage bodies axially, and the hemispherical pockets are designed to fit with the ball crowns. Thus, without changing the ball diameter, the number of hemispherical pockets set in the circumferential direction of the corrugated cage body can be increased, that is, the number of ball pockets in the circumferential direction of the cage can be increased, and the number of balls can be increased, ultimately improving the load-bearing capacity of the bearing.

[0003] In existing technologies, the bearing capacity is mainly increased by increasing the number of balls. However, the number of balls that can be increased is limited, mainly because the space for placing the balls is limited when the inner and outer rings are interlocked. Therefore, this method of increasing the bearing capacity is limited. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high load-bearing deep groove ball bearing, so as to solve the limitation of the prior art described in the background art in terms of increasing the load-bearing capacity by increasing the number of steel balls.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high load-bearing deep groove ball bearing, comprising...

[0006] Steel balls are positioned between the inner and outer rings;

[0007] The first retainer and the second retainer are located in the gap between the inner ring and the outer ring, respectively. The first retainer has a first pocket plate at the position corresponding to the steel ball, and the second retainer has a second pocket plate at the position corresponding to the steel ball. The first pocket plate and the second pocket plate wrap around the outer periphery of the steel ball.

[0008] Two limiting rings are respectively disposed between the inner ring and the outer ring, and the first retainer and the second retainer are located between the two limiting rings. The limiting rings are respectively connected to the first pocket plate and the second pocket plate.

[0009] Several snap-fit ​​components are disposed between the first retainer and the second retainer for connecting the first retainer and the second retainer;

[0010] Two sealing rings are connected to two limiting rings via connecting plates, respectively.

[0011] Preferably, the outer ring and the inner ring are respectively provided with sealing grooves at the positions corresponding to the sealing ring, and the sealing ring extends into the sealing groove.

[0012] Preferably, the snap-fit ​​assembly includes an insert plate disposed on a first retainer, the end of the insert plate away from the first retainer having two V-shaped deformable bodies with a deformation groove between the two deformable bodies, and a socket being disposed on the second retainer at a position corresponding to the insert plate, the insert plate passing through the socket.

[0013] Preferably, the second retainer is provided with a connecting post on the limiting ring, and a stop post is provided on the connecting post, which is inserted into the opening of the deformation groove formed by the two deformable bodies.

[0014] The beneficial effects of adopting the above technical solutions are:

[0015] This application utilizes limiting rings on the first and second abutment plates to prevent relative movement between the inner and outer rings, thereby distributing the force on the steel balls and enabling the entire bearing to withstand greater loads, thus extending its service life.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 In this first embodiment, a high load-bearing deep groove ball bearing includes...

[0024] Steel ball 30 is positioned between inner ring 20 and outer ring 10;

[0025] The first retainer 40 and the second retainer 50 are respectively located in the gap between the inner ring 20 and the outer ring 10. The first retainer 40 has a first pocket plate 41 at the position corresponding to the steel ball 30, and the second retainer 50 has a second pocket plate 51 at the position corresponding to the steel ball 30. The first pocket plate 41 and the second pocket plate 51 wrap around the outer periphery of the steel ball 30.

[0026] Two limiting rings 80 are respectively disposed between the inner ring 20 and the outer ring 10. The first retainer 40 and the second retainer 50 are located between the two limiting rings 80. The limiting rings 80 are respectively connected to the first pocket plate 41 and the second pocket plate 51.

[0027] Several snap-fit ​​components are disposed between the first retainer 40 and the second retainer 50 for connecting the first retainer 40 and the second retainer 50;

[0028] Two sealing rings 90 are connected to two limiting rings 80 via connecting plates 92.

[0029] This embodiment is implemented as follows:

[0030] When this application is used, the first retainer 40 and the second retainer 50 are pushed into the gap between the inner ring 20 and the outer ring 10, respectively. At this time, the snap-fit ​​components on the first retainer 40 and the second retainer 50 will engage, thereby restricting the position of the first retainer 40 and the second retainer 50. At the same time, the two limiting rings 80 will move with the first retainer 40 and the second retainer 50 to the space between the inner ring 20 and the outer ring 10.

[0031] When the bearing is in use, after the bearing is subjected to force, the inner ring 20 and the outer ring 10 will move out of place, and the force will be transmitted to the steel ball 30. When the inner ring 20 and the outer ring 10 move out of place to a certain extent, the inner ring 20 and the outer ring 10 will come into contact with the side wall of the limiting ring 80, so that the limiting ring 80 restricts the misalignment of the inner ring 20 and the outer ring 10, thereby distributing the force on the steel ball 30.

[0032] Please see Figure 2 , 4 The outer ring 20 and the inner ring 10 are respectively provided with sealing grooves 91 at the positions corresponding to the sealing ring 90, and the sealing ring 90 extends into the sealing grooves 91.

[0033] This application improves the sealing effect by using sealing grooves 91 provided on the inner ring 20 and the outer ring 10, which allow the sealing ring 90 to extend into the sealing grooves 91.

[0034] Please see Figure 1 , 23. The snap-fit ​​assembly includes an insert plate 60 disposed on the first retainer 40. Two V-shaped deformable bodies 63 are disposed at the end of the insert plate 60 away from the first retainer 40. A deformation groove 61 is left between the two deformable bodies 63. An insertion hole 62 is disposed on the second retainer 50 at the position corresponding to the insert plate 60, and the insert plate 60 passes through the insertion hole 62.

[0035] In this application, the movement of the first retainer 40 drives the insertion plate 60 to move, and the insertion plate 60 drives the deformable body 63 to move. Since the deformable body 63 is V-shaped, it will be squeezed and deformed when it enters the insertion hole 62 and deforms into the deformation groove 61. When the deformable body 63 passes the insertion hole 62, it resets, which can prevent the insertion plate 60 from disengaging from the insertion hole 62, thus realizing the connection between the first retainer 40 and the second retainer 50.

[0036] Please see Figure 1 , 2 3, 4, 5, The second retainer 50 is provided with a connecting post 71 on the limiting ring 80, and a stop post 70 is provided on the connecting post 71. The stop post 70 is inserted into the opening of the deformation groove 61 formed by the two deformable bodies 63.

[0037] By setting the stop post 70, after the deformable body 63 passes through the insertion hole 62, the stop post 70 is inserted into the opening position of the deformation groove 61 formed by the two deformable bodies 63, so that the two deformable bodies 63 deform outward from the deformation groove 61, increasing the opening size of the deformation groove 61, thereby making the insertion plate 60 less likely to detach from the insertion hole 62.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
