Description

Technical Field

[0001] The utility model relates to the technical field of bearing rings, in particular to an impact-resistant bearing ring. Background Art

[0002] The impact-resistant bearing ring effectively alleviates the impact of external shock and vibration on the mechanical system through its complex structure and exquisite principle. Its structure includes outer ring, inner ring, buffer material and connecting parts. The outer ring is located on the outside of the bearing and bears external shock and vibration; the inner ring is in contact with the bearing and transmits shock and vibration; the buffer material is located between the outer ring and the inner ring as an elastic medium to absorb and reduce the impact of shock and vibration; the connecting parts ensure the stability of the overall structure. Its structural principle is based on the energy absorption and dispersion of elastic materials, as well as the synergistic effect of the outer ring, inner ring and connecting parts;

[0003] For example, an impact-resistant bearing ring disclosed in the authorization announcement number CN219221049U includes: a bearing ring body, a fixing plate is arranged on the front and rear side walls of the bearing ring body, a first reinforcement ring is arranged on the opposite side of the two fixing plates, a second reinforcement ring is arranged on the opposite side of the two fixing plates, a plurality of annular through holes equidistantly distributed are opened on the two fixing plates, a plurality of through grooves corresponding to the positions of the through holes are opened on the bearing ring body, etc. When the two fixing plates are installed, the first reinforcement ring is attached to the inner wall of the bearing ring body, and the second reinforcement ring is attached to the outer wall of the bearing ring body, thereby The first reinforcement ring and the second reinforcement ring are used to strengthen the protection of the inner wall and the outer wall of the bearing ring body and improve its impact resistance.

DETAILED DESCRIPTION

[0018] 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. 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.

[0019] See also Figure 1-4 , the utility model provides an embodiment: an impact-resistant bearing ring, comprising an outer shaft ring 1 and a lower sealing disk 2 fixed at the bottom end of the outer shaft ring 1, an inner shaft ring 3 is coaxially mounted on the top end of the lower sealing disk 2, inner concave holes 301 are provided on the outer walls of both sides of the inner shaft ring 3, an inner ring 7 is mounted inside the inner shaft ring 3, and a plurality of support rings 701 are fixed on the outer circumference of the inner ring 7 in the vertical direction, the setting of the support ring 701 can effectively increase the strength and rigidity of the outer wall of the inner ring 7, so that it can better resist external impact and vibration force, thereby protecting the inner shaft ring 3 and the bearing system from damage by external forces, and an upper dust cover 8 is fixed on the top end of the inner ring 7;

[0020] A card-embedded structure is provided between the bottom end of the upper dust cover 8 and the top end of the outer shaft ring 1 and is rotatably connected. A right-angle cut-out cavity 802 is provided on both sides of the interior of the upper dust cover 8. A dust-proof elastic plug-in structure 11 for plugging with the inner concave hole 301 is installed inside the right-angle cut-out cavity 802. The dust-proof elastic plug-in structure 11 can effectively prevent external dust, impurities, etc. from entering the bearing system. A paddle 10 is slidably installed on the top end of the upper dust cover 8 above the right-angle cut-out cavity 802.

[0021] Both sides of the top of the upper dust cover 8 are provided with hollow grooves 9, and the paddle 10 is slidably installed inside the hollow grooves 9;

[0022] Both ends of the surface of the inner shaft ring 3 are provided with sealing rings 6 that are rotatably connected to the inner wall of the outer shaft ring 1. A retainer 4 is fixed to one end of the surface of the inner shaft ring 3, and a plurality of balls 5 that are in contact with the inner wall of the outer shaft ring 1 are inlaid on the outer wall of the retainer 4. When the external shaft workpiece is set into the inner ring 7, the shaft workpiece drives the inner ring 7, the upper dust cover 8 and the inner shaft ring 3 to rotate together. In this process, the inner ring 7, the retainer 4 and the balls 5 can absorb and alleviate external impacts, and bear the radial and axial loads received by the bearing during operation, thereby transmitting these loads to the outer shaft ring 1 or the mounting plane to ensure the normal operation of the bearing;

[0023] The embedded structure is two steel rings 801 fixed at the edge of the bottom end of the upper dust cover 8. The top of the outer shaft ring 1 is provided with an annular cut-out groove for the steel ring 801 to be embedded. The bottom end of the upper dust cover 8 is rotatably matched with the outer shaft ring 1 through the steel ring 801. The steel ring 801 effectively buffers and disperses the impact energy, so that the upper dust cover 8 can reduce the stress and deformation degree of the outer shaft ring 1 and the inner shaft ring 3 during operation, thereby extending their service life.

[0024] The dustproof elastic plug-in structure 11 comprises a slider 1103 elastically mounted inside the right-angle cut-out cavity 802, and a pin head 1105 mounted on the outer wall of one side of the slider 1103, the pin head 1105 and the inner concave hole 301 are plugged into each other, the top of the slider 1103 is fixedly connected to the bottom end of the paddle 10, a rectangular cut-out groove 1101 is arranged inside the upper dust cover 8 above the right-angle cut-out cavity 802, and a baffle 1102 is slidably mounted inside the rectangular cut-out groove 1101, one end of the baffle 1102 is fixedly connected to the outer wall of one side of the paddle 10, a columnar groove is arranged inside the slider 1103, and a coil spring 1104 is mounted inside the columnar groove, and one end of the coil spring 1104 is fixedly connected to the inner wall of one side of the right-angle cut-out cavity 802;

[0025] The staff manually moves the paddle 10, so that the paddle 10 drives the slider 1103 and the baffle 1102 away from the vertical center line of the inner shaft ring 3. During this process, the baffle 1102 slides inside the rectangular cut-out groove 1101, thereby always keeping the right-angle cut-out cavity 802 in a sealed state. At this time, the coil spring 1104 is in a compressed state, and the pin head 1105 is no longer plugged into the inner recessed hole 301. At this time, the staff can easily and quickly remove the dust cover 8, which is convenient for users to perform maintenance and repair operations.

[0026] When the embodiment of the present application is in use, the staff first takes out the inner ferrule 7 to be connected with the inner shaft ring 3, so that the inner ferrule 7 is concentrically inserted into the inner shaft ring 3. At this time, the bottom end of the upper dust cover 8 is preliminarily connected to the top end of the outer shaft ring 1 through the card embedding structure. When the upper dust cover 8 and the outer shaft ring 1 are installed in place, the movable end of the dustproof elastic plug-in structure 11 cooperates with the inner concave hole 301. At this time, the inner ferrule 7, the upper dust cover 8 and the inner shaft ring 3 complete the quick installation operation. When inspecting and maintaining the inner ferrule 7 and the upper dust cover 8, the staff manually dials The shift plate 10 is moved so that the shift plate 10 drives the movable end of the dustproof elastic plug structure 11 to withdraw to the outside of the inner recessed hole 301, thereby releasing the connection between the upper dust cover 8 and the inner shaft ring 3, that is, the two can be separated normally. The quick-release function of the upper dust cover 8 and the inner ferrule 7 is realized by the shift plate 10, the hollow groove 9, the dustproof elastic plug structure 11 and other components, so that maintenance personnel can easily and quickly inspect, clean or replace related accessories without using complicated tools, and the maintenance operation is simpler, reducing the complexity and tediousness of manual operation.
