Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to an extended tapered roller bearing. Background Technology

[0002] Extended tapered roller bearings are a special design of tapered roller bearings, with increased roller length compared to ordinary tapered roller bearings. They are separable bearings, with tapered raceways on both the inner and outer rings. The rollers are frustum-shaped and arranged between the inner and outer ring raceways. This design ensures that the contact lines between the rollers and raceways, when extended, intersect at the same point on the bearing axis, achieving pure rolling. Extended tapered roller bearings can withstand larger combined radial and axial loads; the larger the contact angle, the higher the axial load capacity. They are widely used in mechanical equipment requiring high load capacity and stability.

[0003] However, existing extended tapered roller bearings have a fixed inner diameter, which cannot be flexibly adjusted according to different usage scenarios. When faced with various equipment specifications or changes in working conditions, their adaptability is insufficient, affecting the performance. In addition, the bearing body components are tightly connected, making disassembly cumbersome and consuming a lot of time and effort, and maintenance is relatively inconvenient.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides an extended tapered roller bearing, which has the effect of easy disassembly and assembly, greatly facilitating inspection and maintenance. At the same time, the inner diameter of the bearing body can be adjusted to adapt to different usage scenarios, improve the versatility of use, and meet diverse needs.

The positioning mounting ring is fixedly connected to the bearing body through the fixed connection assembly. The rotary extrusion propulsion assembly is fixedly installed on the positioning mounting ring. The positioning mounting ring is evenly provided with arc-shaped limiting holes and grooves. The rolling inner connection assembly is slidably inserted into the arc-shaped limiting holes and grooves. One end of the rolling inner connection assembly is inserted into the bearing body, and the rolling inner connection assembly is evenly distributed circumferentially in the bearing body. The rotary extrusion propulsion assembly is connected to the rolling inner connection assembly.

The external threaded insertion ring is fixed on the positioning mounting ring, and the external threaded insertion ring is threadedly inserted into a threaded insertion hole opened at one end of the bearing body.

[0008] Preferably, in order to further secure the positioning mounting ring by means of the first fixing screw, the first fixing screw passes through the positioning mounting ring and is threaded into the connecting screw hole opened on the bearing body.

[0009] Preferably, in order to control the rotation of the annular rotating block and compress the rolling inner connecting component, the rotary compression propulsion component includes the annular rotating block, on which compression grooves are uniformly formed, and one end of the rolling inner connecting component is inserted into the compression groove.

[0010] Preferably, in order to fix the annular rotating block after rotation by means of the extended fixing head and the second fixing screw, the extended fixing head is fixedly installed on the outer wall of the annular rotating block, and the extended fixing head is fixedly connected to the positioning mounting ring by the second fixing screw.

[0011] Preferably, in order to control the rotation of the annular rotating block so that the extrusion groove can extrude the smooth driven rod, thereby causing the smooth driven rod to slide in the arc-shaped limiting groove, the rolling inner connecting assembly includes the smooth driven rod, one end of which passes through the extrusion groove and is slidably inserted into the arc-shaped limiting hole groove.

[0012] Preferably, in order to enable the extension block to move via the smooth driven rod, the extension block is fixedly installed at the other end of the smooth driven rod.

[0013] Preferably, in order for the smooth driven rod to move the inner diameter adjusting roller via the extension strip, the inner diameter adjusting roller is rotatably mounted on one end of the extension strip, and the inner diameter adjusting roller is evenly distributed circumferentially within the bearing body.

[0014] The beneficial effects of this utility model are: the positioning mounting ring can be easily fixed or disassembled with the bearing body through the fixed connection component, which greatly facilitates inspection and maintenance; the inner diameter of the bearing body can be adjusted by operating the rotary extrusion propulsion component to adapt to different usage scenarios, improve the versatility of use, and meet diverse needs.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-5 As shown, this embodiment provides an extended tapered roller bearing, including a bearing body 1. A positioning mounting ring 2 is installed at one end of the bearing body 1. The positioning mounting ring 2 is fixedly connected to the bearing body 1 via a fixed connecting assembly 3. A rotary extrusion and propulsion assembly 4 is fixedly installed on the positioning mounting ring 2. Arc-shaped limiting slots are evenly opened on the positioning mounting ring 2. A rolling inner connecting assembly 5 is slidably inserted into the arc-shaped limiting slots. One end of the rolling inner connecting assembly 5 is inserted into the bearing body 1, and the rolling inner connecting assemblies 5 are evenly distributed circumferentially within the bearing body 1. The rotary extrusion and propulsion assembly 4 is connected to the rolling inner connecting assembly 5. In use, the positioning mounting ring 2 is fixed to the bearing body 1 via the fixed connecting assembly 3, which facilitates disassembly and makes maintenance more convenient. Then, the rotary extrusion and propulsion assembly 4 is operated to rotate and exert a squeezing effect on the rolling inner connecting assembly 5. The rolling inner connecting assembly 5 slides in the arc-shaped limiting slots, and its end located in the bearing body 1 moves accordingly, thereby changing the position of related components and realizing the adjustment of the bearing inner diameter, improving its versatility.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 2As shown, the fixed connection assembly 3 includes an external threaded insertion ring 301 and a first fixing screw 302. The external threaded insertion ring 301 is fixed on the positioning mounting ring 2, and the external threaded insertion ring 301 is threadedly inserted into a threaded insertion hole at one end of the bearing body 1. The first fixing screw 302 passes through the positioning mounting ring 2, and the first fixing screw 302 is threadedly inserted into a connecting screw hole on the bearing body 1. In use, the external threaded insertion ring 301 on the positioning mounting ring 2 is aligned with the threaded insertion hole at one end of the bearing body 1, and the positioning mounting ring 2 is rotated to screw the external threaded insertion ring 301 into the threaded insertion hole, completing the initial fixing. Next, the first fixing screw 302 is passed through the positioning mounting ring 2, aligned with the corresponding connecting screw hole on the bearing body 1, and the first fixing screw 302 is rotated to screw it into the connecting screw hole, further strengthening the connection between the positioning mounting ring 2 and the bearing body 1.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 4 and Figure 5 As shown, the rotary extrusion propulsion assembly 4 includes an annular rotating block 401, on which extrusion grooves are evenly distributed. One end of the rolling inner connecting assembly 5 is inserted into the extrusion groove. An extension fixing head 402 is fixedly installed on the outer wall of the annular rotating block 401. The extension fixing head 402 is fixedly connected to the positioning mounting ring 2 by a second fixing screw 403. The rolling inner connecting assembly 5 includes a smooth driven rod 501. One end of the smooth driven rod 501 passes through the extrusion groove and is slidably inserted into the arc-shaped limiting hole groove. An extension strip 502 is fixedly installed on the other end of the smooth driven rod 501. An inner diameter adjusting roller 503 is rotatably installed on one end of the extension strip 502. The inner diameter adjusting roller 503 is evenly distributed circumferentially in the bearing body 1. In use, the fixing of the second fixing screw 403 between the extension fixing head 402 and the positioning mounting ring 2 is released. Next, rotate the annular rotating block 401. The extrusion groove on it will extrude on one end of the smooth driven rod 501 inserted therein. Since the other end of the smooth driven rod 501 is slidably inserted into the arc-shaped limiting hole groove, the smooth driven rod 501 will slide under the extrusion, driving the extension strip 502 to move, which in turn causes the inner diameter adjusting roller 503 rotatably installed at one end of the extension strip 502 to move. After the adjustment is in place, the extension fixing head 402 is fixed with the second fixing screw 403.
