Abstract
Description
A multi-positioning cylindrical roller bearing Technical Field
[0001] This utility model relates to the field of cylindrical roller bearing technology, and in particular to a multi-positioning cylindrical roller bearing. Background Technology
[0002] With the continuous advancement of technology, bearings, as one of the important mechanical components, have become increasingly diverse in form. Among them, cylindrical roller bearings are one of the most widely used bearings. However, as the matching requirements between mechanical components become more and more stringent, traditional cylindrical roller bearings are increasingly unable to meet production requirements.
[0003] Traditional cylindrical roller bearings consist of an outer ring, an inner ring, rollers, and a cage, all of which are separate. This causes the cage and rollers to frequently move axially between the outer and inner rings. Furthermore, traditional cages occupy a large amount of space, reducing the bearing's load capacity. Summary of the Invention
[0004] The purpose of this utility model is to provide a multi-limit cylindrical roller bearing that integrates the traditional cage and inner ring into a single design. The outer ring is double-plate, and the rollers are provided with grooves that can be engaged with the outer ring and inner ring respectively without affecting normal rotation. This results in a smaller gap between the outer ring and inner ring, stronger bearing capacity, and the internal rollers cannot move axially due to the limiting effect of the outer and inner rings.
[0005] To achieve the above objectives, a multi-positioning cylindrical roller bearing is provided, comprising: an outer ring assembly, an inner ring assembly, and a roller assembly. The outer ring assembly includes an outer ring, an inner bore, an outer hole, a retaining ring, a top groove, and a retaining pin. The inner circumferential surface of the outer ring has an inner hole and an outer hole. A retaining ring is fixedly connected to the side wall of the outer ring. A top groove is provided on the circumferential surface of the outer ring, and a retaining pin is provided inside the top groove. The inner ring assembly includes an inner ring and a retaining ring. A retaining ring is fixedly connected to the circumferential surface of the inner ring. The retaining ring is semi-circular. The roller assembly includes rollers and a retaining groove. A retaining groove is provided on the circumferential surface of the rollers.
[0006] According to the aforementioned multi-position cylindrical roller bearing, there are two outer ring assemblies arranged symmetrically front to back, and the inner ring assembly and roller assembly are both located inside the two outer ring assemblies.
[0007] According to the aforementioned multi-position cylindrical roller bearing, the rollers and the outer ring are engaged through an inner hole, an outer hole, and a groove.
[0008] According to the aforementioned multi-position cylindrical roller bearing, the rollers and retaining rings are engaged via retaining grooves.
[0009] According to the aforementioned multi-position cylindrical roller bearing, the retaining ring and the inner ring are integrally formed.
[0010] According to the aforementioned multi-position cylindrical roller bearing, the top groove is semi-annular, the retaining post is semi-cylindrical, and clamping rings are engaged on the retaining posts of the front and rear outer ring assemblies, with the clamping rings located inside the top groove.
[0011] The above solution has the following advantages: by setting up an outer ring assembly, an inner ring assembly, a roller assembly, and a clamping ring, the traditional cage and inner ring are integrated into a single design. The outer ring adopts a double-piece design, and the rollers are provided with grooves that can be engaged with the outer ring and inner ring respectively without affecting normal rotation. This results in a smaller gap between the outer ring and the inner ring, stronger bearing capacity, and the internal rollers cannot move axially under the constraint of the outer ring and the inner ring.

[0024] Referring to Figures 1-5, an embodiment of this utility model discloses a multi-positioning cylindrical roller bearing, comprising: an outer ring assembly 1, an inner ring assembly 2, and a roller assembly 3. The outer ring assembly 1 includes an outer ring 101, an inner hole 102, an outer hole 103, a retaining ring 104, a top groove 105, and a retaining post 106. The inner circumferential surface of the outer ring 101 is provided with the inner hole 102 and the outer hole 103. The retaining ring 104 is fixedly connected to the side wall of the outer ring 101. The top groove 105 is provided on the circumferential surface of the outer ring 101, and the retaining post 106 is provided inside the top groove 105. The inner ring assembly 2 includes an inner ring 201 and a retaining ring 202, which is integrally formed with the inner ring 201. The bearing uses a retainer 202 instead of a traditional cage, which reduces the gap between the retainer 202 and the inner ring 201 and outer ring 101, resulting in a stronger bearing capacity. Multiple retainers 202 are evenly distributed on the circumferential surface of the inner ring 201. Each retainer 202 has a pocket, and rollers 301 are located inside the pocket. Retainers 202 are fixedly connected to the circumferential surface of the inner ring 201, and each retainer 202 is semi-circular. The roller assembly 3 includes rollers 301 and grooves 302. Multiple rollers 301 are arranged corresponding to the retainers 202.
[0025] There are two outer ring assemblies 1, which are symmetrically arranged front and back. The inner ring assembly 2 and the roller assembly 3 are both located inside the two outer ring assemblies 1. The roller 301 is engaged with the outer ring 101 through the inner hole 102, the outer hole 103 and the groove 302. The roller 301 is engaged with the retaining ring 202 through the groove 302. During installation, the outer side of the roller 301 is engaged in the inner hole 102 and the outer hole 103 of the two outer rings 101, and the inner side is engaged in the retaining ring 202, forming a double limit to prevent the roller 301 from moving axially.
[0026] The top groove 105 is semi-annular, and the locking post 106 is semi-cylindrical. There are multiple top grooves 105 and locking posts 106, which are evenly distributed on the circumferential surface of the outer ring 101. Clamping rings 4 are engaged on the locking posts 106 in the two outer ring assemblies 1. The clamping rings 4 are located inside the top groove 105. There are multiple clamping rings 4, which are arranged corresponding to the top groove 105 and the locking posts 106. The two outer rings 101 are connected so that the locking posts 106 form a complete cylinder and the top groove 105 forms a complete annular groove. Then, the decorative clamping rings 4 are inserted into the top groove 105, and the inner circumferential surface of the clamping rings 4 clamps the locking posts 106, thereby fixing the two outer rings 101.
[0027] Working principle: During installation, the groove 302 of the roller 301 is inserted into the retaining ring 202 of the inner ring 201. Then, the two outer rings 101 wrap around the inner ring 201 and the roller 301 from both sides, with the inner hole 102 and the outer hole 103 located on the outside of the roller 301 and engaged with and limited the roller 301. After the two outer rings 101 are aligned, the retaining post 106 forms a complete cylinder, and the top groove 105 forms a complete annular groove. Then, the decorative clamping ring 4 is inserted into the top groove 105, and the inner circumferential surface of the clamping ring 4 clamps the retaining post 106, thereby fixing the two outer rings 101 and completing the installation of the cylindrical bearing. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
