[0003] Traditional bearing caps are assembled using multiple sets of symmetrical fasteners. During later maintenance and disassembly, multiple sets of fastener components, including bolts, washers, nuts, and other accessories, need to be disassembled. This process is cumbersome, time-consuming, and labor-intensive, affecting maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a bearing cover that is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bearing cover that is easy to assemble and disassemble includes a bearing cover and a mounting ring. A rotating ring is rotatably mounted on the outer side of the mounting ring. The bearing cover is snapped into the middle of the mounting ring. Multiple planar extrusion blocks are provided on the outer side of the bearing cover. One side of the planar extrusion blocks is in extrusion contact with multiple extrusion blocks provided on the outer side of the rotating ring.

[0007] The outer side of the bearing cover is equipped with multiple planar extrusion blocks in a circular array. One side of each planar extrusion block is connected to an inclined guide block, and multiple mating holes are staggered in the middle of each planar extrusion block.

[0008] Multiple extrusion blocks are installed on one side of the rotating ring. The inner wall of the extrusion block is pressed and fitted against the flat extrusion block. An installation groove is opened on the inner wall of the extrusion block. A limit bead is installed in the installation groove by a spring. One side of the limit bead protrudes from the installation groove and fits into the docking hole.

[0009] Furthermore, in a preferred configuration, a mating post is installed on the inner center of the planar extrusion block, and the mating post is inserted into a corresponding insertion hole on the outer wall of the mounting ring.

[0010] In addition, a preferred structure is that a rubber pad is installed on the inner wall of the insertion hole, and the rubber pad is in pressure contact with the mating post.

[0011] In addition, a preferred structure is that the outer walls of the planar extrusion block and the inclined guide block are coated with a wear-resistant coating.

[0012] In addition, a preferred structure is that the outer wall of the mounting ring has a limiting groove, a rotating ring is installed in the limiting groove, and a fastening bolt is screwed to one side of the outer wall of the rotating ring, the fastening bolt passes through the rotating ring and extends into the limiting groove.

[0013] Furthermore, in a preferred configuration, the lowest inclined surface of the inclined guide block is in close contact with the outer wall of the mounting ring.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the assembly operation of the bearing cover is achieved through the mounting ring and the rotating ring. Rotating the rotating ring drives the pressing block to connect with the pressing block mechanism on the outside of the bearing cover, thereby pressing the bearing cover inward to improve the connection stability with the mounting ring. The disassembly operation can be completed by simply rotating the rotating ring in the opposite direction. At the same time, the installation stability of the rotating ring and the bearing cover is improved by the fastening bolts and the limit bead locking mechanism, effectively improving the disassembly and assembly efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A bearing cover that is easy to disassemble and assemble includes a bearing cover 1 and a mounting ring 2. A rotating ring 3 is mounted on the outer side of the mounting ring 2 for limiting rotation. The bearing cover 1 is snapped into the middle of the mounting ring 2. A plurality of flat pressing blocks 11 are provided on the outer side of the bearing cover 1. One side of the flat pressing block 11 is pressed and contacted with a plurality of pressing blocks 31 provided on the outer side of the rotating ring 3.

[0024] Multiple planar extrusion blocks 11 are installed in a ring array on the outer side of the bearing cover 1. A sloping guide block 12 is connected to one side of the planar extrusion block 11. Multiple mating holes 13 are staggered in the middle of the planar extrusion block 11.

[0025] The docking hole 13 and the limiting bead 6 are a locking mechanism for each other.

[0026] Multiple extrusion blocks 31 are installed on one side of the rotating ring 3. The inner wall of the extrusion block 31 is pressed and fitted with the flat extrusion block 11. An installation groove 7 is opened on the inner wall of the extrusion block 31. A limit bead 6 is installed in the installation groove 7 by means of a spring 5. One side of the limit bead 6 protrudes from the installation groove 7 and fits into the docking hole 13.

[0027] When the limiting bead 6 is compressed and moved, the spring 5 deforms.

[0028] A docking post 14 is installed in the middle of the inner side of the flat extrusion block 11, and the docking post 14 is inserted into the insertion hole 22 opened on the outer wall of the mounting ring 2.

[0029] The mating post 14 and the insertion hole 22 are interlocking structures to complete the post groove snap-fit ​​connection.

[0030] A rubber pad 8 is installed on the inner wall of the insertion hole 22, and the rubber pad 8 is in contact with the mating post 14 by compression.

[0031] The outer walls of the flat extrusion block 11 and the inclined guide block 12 are coated with a wear-resistant coating 15.

[0032] The wear-resistant coating 15 can be a polytetrafluoroethylene coating.

[0033] A limiting groove 21 is formed on the outer wall of the mounting ring 2. A rotating ring 3 is installed in the limiting groove 21, and the rotating ring 3 can rotate freely through the limiting groove 21.

[0034] A fastening bolt 4 is screwed onto one side of the outer wall of the rotating ring 3. The fastening bolt 4 passes through the rotating ring 3 and extends into the limiting groove 21. When the fastening bolt 4 is tightened, the fastening bolt 4 is pressed and rubbed against the inner wall of the limiting groove 21 to prevent the rotating ring 3 from shifting, thus playing a safety role.

[0035] The lowest inclined surface of the inclined guide block 12 fits and connects with the outer wall of the mounting ring 2, so that the extrusion block 31 can be guided and connected with the inclined guide block 12.

[0036] In this embodiment, the mounting ring 2 is assembled to the designated mounting surface by fasteners, and the mating post 14 on one side of the bearing cover 1 is inserted into the insertion hole 22 opened on the outer wall of the mounting ring 2 to complete the initial mating. Then, by rotating the rotating ring 3, the pressing block 31 moves towards the inclined guide block 12 on the outer side of the bearing cover 1. When the inner wall of the pressing block 31 is pressed into contact with the outer wall of the inclined guide block 12, under the action of the inclined guide, the pressing block 31 generates an inward pressing force on the inclined guide block 12, so that the bearing cover 1 is pressed and connected to the mounting ring 2 as a whole.

[0037] When the extrusion block 31 rotates to the flat extrusion block 11, the limiting bead 6 inside the extrusion block 31 is engaged with the mating hole 13 on the outer wall of the flat extrusion block 11, forming a snap-fit ​​structure to ensure the connection operation between the rotating ring 3 and the bearing cover 1.

[0038] When the mating post 14 is inserted into the insertion hole 22, the mating post 14 and the rubber pad 8 are pressed into contact. As the bearing cover 1 and the mounting ring 2 are pressed together, the rubber pad 8 is compressed to generate a counterforce, ensuring installation stability.

[0039] By tightening the fastening bolt 4, the fastening bolt 4 is driven to make contact with the inner wall of the limiting groove 21 through compression and friction, so as to prevent the rotating ring 3 from shifting and play a safety role.

[0040] The bearing cover 1 can be pressed by rotating the rotating ring to ensure that the bearing cover 1 is stably and tightly installed on the mounting ring 2 to achieve the installation function. At the same time, the limiting bead 6 and the mating hole 13 and other components form a snap-fit ​​mechanism to ensure the installation stability of the bearing cover 1. Meanwhile, the bearing cover 1 can be disassembled by simply rotating the rotating ring 3 in the opposite direction, eliminating the need to disassemble fasteners such as nuts, bolts, and washers, and significantly improving the disassembly and assembly efficiency.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
