Description

Technical Field

[0001] This utility model relates to the field of high-load rolling bearing technology, and in particular to a high-load rolling bearing. Background Technology

[0002] A high-load rolling bearing is a bearing specifically designed to withstand high radial and / or high axial loads. For example, a high-load rolling bearing, publication number CN219953956U, features multiple rolling steel balls that are held at a fixed distance by a cage. The rolling steel balls are simultaneously connected to both the outer and inner rings of the bearing and roll within a first and second annular recess, allowing the outer and inner rings to rotate relative to each other. When force is applied to the outer ring, the reinforcing rod and filler plate work together to form a structure similar to a reinforcing rib, reducing the deformation of the outer ring when subjected to a large radial force. This reduces the amount of external force transmitted to the inner ring via the rolling steel balls, thus reducing the deformation of the inner ring and extending the bearing's service life.

[0003] However, the combination of the reinforcing rod and the filler plate in the existing design is relatively simple, which may lead to local stress concentration under high loads. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-load rolling bearing.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a high-load rolling bearing includes a bearing 1. Both sides of the bearing 1 are provided with an outer ring 2 and an inner ring 3 coaxially distributed. An outer ring 5 is provided on the outer side of the outer ring 2, threadedly connected to the inner edge of the outer ring of the bearing 1. An inner ring 11 is provided on the inner side of the inner ring 3, threadedly connected to the outer edge of the inner ring of the bearing 1. A plurality of outer reinforcing ribs 8 are provided between the inner edge of the outer ring 5 and the outer edge of the outer ring 2. A plurality of inner reinforcing ribs 13 are provided between the outer edge of the inner ring 11 and the inner edge of the inner ring 3. A plurality of support ribs 4 are inserted into the end face of the outer ring 2, slidably connected to the outer edge of the inner ring 3. The plurality of outer reinforcing ribs 8 and inner reinforcing ribs 13 are arranged in a ring array about the central axis of the bearing 1. The plurality of outer reinforcing ribs 8 can achieve [the desired effect] with the bearing 1. The outer ring 5 connected to the outer ring 2 has multiple connection points, and the set of several support ribs 4 can ensure that the outer ring 2 and the inner ring 3 are rigidly connected and in contact, and can transmit force. Similarly, the set of several inner reinforcing ribs 13 can realize that the inner ring 11 and the inner ring 3 embedded in the bearing 1 have multiple connection points, thereby realizing the transmission of force. Therefore, by using several connection points and contact points, when the outer ring of the bearing 1 is subjected to pressure in one direction, the pressure is transmitted and evenly distributed to the end face of the bearing 1 by the formed connection points and contact points, ensuring that there is no stress concentration. Furthermore, by using the rotational connection between the support ribs 4 and the outer side of the inner ring 3, it is ensured that the inner ring and the outer ring of the bearing 1 can rotate smoothly and independently.

[0024] Further description of the structure of the outer ring 5 and the inner ring 11: The edge of the outer ring 5 extends outward to overlap with the edge of the outer ring of the bearing 1, and the edge of the inner ring 11 extends outward to overlap with the edge of the inner ring of the bearing 1. This ensures that when the outer ring 5 and the inner ring 11 are screw-installed, the overlap at the edge position can prevent the outer ring 5 and the inner ring 11 from being over-installed or under-installed, thus ensuring that the installation position of the outer ring 5 and the inner ring 11 is fixed.

[0025] To ensure the fixed positions of the outer reinforcing ribs 8 and 13: several studs 12 arranged in a ring array around the central axis of bearing 1 are fixedly installed on the surfaces of the outer ring 5, outer ring 2, inner ring 3, and inner ring 11. The ends of the outer reinforcing ribs 8 and 13 are inserted into the surfaces of the studs 12. The outer reinforcing ribs 8 and 13 are set as follows: Figure 3 As shown, it has four endpoints. Therefore, by using the outer reinforcing rib 8 to be inserted into the studs 12 on the outer ring 5 and the outer ring 2, and the inner reinforcing rib 13 to be inserted into the studs 12 on the inner ring 3 and the inner ring 11, the installation spacing of the outer reinforcing rib 8 and the inner reinforcing rib 13 can be fixed.

[0026] To ensure the fixed position of the support rib 4: the inner wall of the support rib 4 is rolled to the end of the inner roller of the bearing 1. A plug ring 15 is fixedly installed between several support ribs 4 and sleeved on the outer wall of the outer ring 2. Several slots 10 are provided on the end face of the outer ring 2 in a ring array about the central axis of the bearing 1. The support rib 4 is inserted into the slot 10. The plug ring 15 is inserted into several studs 12 on the outer side of the outer ring 2 and the surface of the plug ring 15 is rotatably connected to a nut that is threaded to the stud 12.

[0027] To prevent the outer reinforcing rib 8 and the inner reinforcing rib 13 from falling off: Threaded rings 6 are threadedly connected to the inner sides of both the outer ring 5 and the inner ring 3. A rotating ring 7 is rotatably connected to the end face of the threaded ring 6. Several sleeves 14, arranged in a ring array around the central axis of the bearing 1, are fixedly installed on one side of the rotating ring 7. The two rotating rings 7 are coaxial but have different diameters. The sleeves 14 on the outer rotating ring 7 are inserted into the studs 12 on the outer ring 5. When the sleeves 14 on the inner rotating ring 7 are inserted into the studs 12 on the inner ring 3, the outer thread is screwed in. Ring 6 enables the outer rotating ring 7 to move towards several outer reinforcing ribs 8 until several sleeves 14 on the end face of the outer rotating ring 7 are inserted into the studs 12 inside the outer ring 5 and abut against one side of the outer reinforcing rib 8 to prevent the outer reinforcing rib 8 from falling off. Similarly, by screwing the inner threaded ring 6, the inner rotating ring 7 is moved towards several inner reinforcing ribs 13 until several sleeves 14 on the end face of the inner rotating ring 7 are inserted into the studs 12 inside the inner ring 3 and abut against one side of the inner reinforcing rib 13 to prevent the inner reinforcing rib 13 from falling off.

[0028] Several locking blocks 16, arranged in a ring array around the central axis of bearing 1, are inserted into the outer wall of the outer ring 5. These locking blocks 16 are used to engage with the inner side of the outer ring of bearing 1, and a spring rod 9 is provided between the locking blocks 16 and the outer ring 5. One side of the locking block 16 is inclined and slidably connected to the side of the outer rotating ring 7. Figure 4 As shown, when the outer threaded ring 6 is rotated and installed, the side of the outer rotating ring 7 will contact the inclined surface on the bottom right side of the locking block 16, which will push the locking block 16 to overcome the tension of the spring rod 9 and move to the inner side of the outer ring of the inserted bearing 1. By using the flat part on the top right side of the locking block 16 to contact the inner wall of the outer ring of the bearing 1, the relative position of the outer ring 5 and the outer ring of the bearing 1 can be fixed.

[0029] Working principle: After bearing 1 is assembled, the outer ring 5 and inner ring 11 are first threaded on. After the outer ring 5 and inner ring 11 are installed, the outer ring 2 and inner ring 3 are placed between the outer ring 5 and inner ring 11. The relative position of the outer ring 5 and outer ring 2 is fixed by inserting several outer reinforcing ribs 8 into the studs 12 on the outer ring 5 and outer ring 2. Then, the position is fixed by inserting several inner reinforcing ribs 13 into the studs 12 on the inner ring 11 and inner ring 3, thereby fixing the relative position of the inner ring 11 and inner ring 3. The insertion of the support ribs 4 into the slots 10 enables several support ribs 4 to be installed between the outer ring 2 and the inner ring 3. The position is fixed by inserting the insertion ring 15 into the stud 12 on the outer ring 2. The position of the insertion ring 15 is fixed by rotating the installation nut on the insertion ring 15 and using the threaded connection between the nut and the stud 12. This fixes the position of the support ribs 4. Finally, two threaded rings 6 are screwed on. The sleeve 14 on the end face of the threaded ring 6 is inserted into the stud 12 to fix the position of the outer reinforcing ribs 8 and the inner reinforcing ribs 13.
