[0001] This utility model relates to the field of bearing technology, specifically to an assembled bearing structure. Background Technology

[0002] Bearings are important components that support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure rotational accuracy. The bearing bush is the part that contacts the bearing and the journal. Bearing bushes are usually divided into upper and lower structures and do not rotate with the shaft. Therefore, during installation, the bearings need to be installed layer by layer and the journal needs to be placed. When the overall weight of the shaft is large, the placement is more difficult and it is not convenient to assemble.

[0003] To address the aforementioned issues, we have made improvements and proposed an assembled bearing structure. Utility Model Content

[0006] As a preferred technical solution of this utility model, the surfaces of the upper and lower slide plates are provided with a plurality of corresponding through holes, and a plurality of balls are respectively located in the plurality of through holes, and the inner diameter of the plurality of through holes is smaller than the diameter of the balls. A support member is fixedly connected between the upper and lower slide plates, and the balls are rotatably connected to both the upper and lower slide plates. One end of the spring assembly is connected to the lower surface of the lower slide plate, and the other end of the spring assembly is fixedly connected to the inner bottom surface of the reserved groove.

[0007] As a preferred technical solution of this utility model, the clamp is a T-shaped structure, and the bearing is divided into a first bearing and a second bearing that are spliced ​​from left to right. The first bearing and the second bearing are respectively provided with a groove at the edge where they are spliced. The inner surface of the first bearing and the second bearing after the grooves are spliced ​​together fits with the outer surface of the clamp.

[0008] As a preferred technical solution of this utility model, the bottom groove is located on both sides of the mounting groove of the bearing seat, the plug is located on both sides of the mounting groove of the bearing cover, the inner surface of the two mounting grooves after being joined together is a complete circle, the plug and the bottom groove are inserted together, and a corresponding fixing hole is opened on the outer surface of the bottom groove and the plug respectively, and a connecting bolt is threaded into the fixing hole.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1-5 As shown, an assembled bearing structure includes a bearing housing 1 and a bearing cover 2. A left and right split bearing bush 3 is provided between the bearing housing 1 and the bearing cover 2. A bottom groove 10 is provided on the upper surface of the bearing housing 1. An insert 9 is connected to the lower part of the bearing cover 2. An arc-shaped mounting groove 6 is provided on the upper part of the bearing housing 1 and the lower part of the bearing cover 2. Several reserved grooves 12 are provided on the inner surface of the mounting groove 6. A clamp 11 is installed inside the mounting groove 6. An upper sliding plate 14 and a lower sliding plate 15 are slidably connected to the inner surface of the reserved groove 12. Several balls 16 and spring groups 17 are provided in the reserved groove 12.

[0023] The surfaces of the upper slide plate 14 and the lower slide plate 15 are each provided with a number of corresponding through holes. A number of balls 16 are located in the number of through holes, and the inner diameter of the through holes is smaller than the diameter of the balls 16. This allows the upper slide plate 14 and the lower slide plate 15 to restrict the up and down movement of the balls 16, preventing the balls 16 from coming out of the limits of the upper slide plate 14 and the lower slide plate 15. A support is fixedly connected between the upper slide plate 14 and the lower slide plate 15 to maintain the distance between them. The balls 16 are rotatably connected to both the upper slide plate 14 and the lower slide plate 15. One end of the spring assembly 17 is connected to the lower surface of the lower slide plate 15, and the other end of the spring assembly 17 is fixedly connected to the inner bottom surface of the reserved groove 12. The balls 16 roll during the process of being pushed into the bearing bush 3, reducing the friction between the outer surface of the bearing bush 3 and the mounting groove 6 of the bearing seat 1. Gravity will press the balls 16 down so that they are completely submerged in the reserved groove 12. At this time, the spring assembly 17 is compressed.

[0024] The clamp 11 has a T-shaped structure. When the groove 13 of the bearing shell 3 is assembled with the clamp 11, the T-shaped structure of the clamp 11 can prevent the two bearing shells 3 from separating and continuously clamp the journal. The bearing shell 3 is divided into a first bearing shell 301 and a second bearing shell 302 that are spliced ​​on the left and right. The groove 13 is opened at the edge of the splicing of the first bearing shell 301 and the second bearing shell 302 respectively. The inner surface of the groove 13 of the first bearing shell 301 and the second bearing shell 302 after being spliced ​​is in contact with the outer surface of the clamp 11.

[0025] The bottom groove 10 is located on both sides of the mounting groove 6 of the bearing housing 1, and the insert 9 is located on both sides of the mounting groove 6 of the bearing cover 2. The inner surface of the two mounting grooves 6 after being joined together is a complete circle. The journal is clamped, and the insert 9 and the bottom groove 10 are inserted. The outer surface of the bottom groove 10 and the insert 9 are respectively provided with corresponding fixing holes 7. The fixing holes 7 are internally threaded with connecting bolts 8. After inserting the insert 9 into the bottom groove 10, the fixing holes 7 of the insert 9 and the bottom groove 10 are aligned, and then the connecting bolts 8 are screwed in to connect and fasten the bearing cover 2 and the bearing housing 1.

[0026] The top of the bearing cover 2 is provided with an oil injection hole 5, which penetrates downward through the bearing shell 3 and communicates with the interior of the bearing shell 3. Lubricating oil is injected through the oil injection hole 5, so that the lubricating oil forms an oil film between the bearing shell 3 and the journal, thus avoiding direct friction between the bearing shell 3 and the journal.

[0027] The bearing housing 1 has fastening bolts 4 threadedly connected to both ends, which fixes the bearing structure as a whole onto the mounting base.

[0028] Working principle: In this type of assembled bearing structure, after inserting the plug 9 into the bottom groove 10, aligning the plug 9 and the fixing hole 7 of the bottom groove 10, screw in the connecting bolt 8 to connect and secure the bearing cover 2 and the bearing seat 1. After fitting the first bearing shell 301 and the second bearing shell 302 onto the outside of the journal, push them as a whole into the mounting groove 6 of the bearing seat 1. The ball 16 rolls during the process of pushing into the bearing shell 3, reducing the friction between the outer surface of the bearing shell 3 and the mounting groove 6 of the bearing seat 1. Gravity will press the ball 16 down so that it is completely submerged in the reserved groove 12. At this time, the spring assembly 17 is compressed. After the slot 13 of the bearing shell 3 is assembled with the clip 11, the T-shaped structure of the clip 11 can prevent the two bearing shells 3 from separating and continuously clamp the journal. Lubricating oil is injected from the oil injection hole 5, so that the lubricating oil forms an oil film between the bearing shell 3 and the journal, avoiding direct friction between the bearing shell 3 and the journal.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
