Description

Technical Field

[0001] This utility model relates to the field of tapered roller bearing technology, and specifically discloses a tapered roller bearing. Background Technology

[0002] A tapered roller bearing generally consists of an inner ring, an outer ring, a cage, and several tapered rolling elements. The cage is used to fit the inner ring and position the tapered rolling elements. The three components form the inner assembly, which is then fitted into the outer ring to form the tapered roller bearing.

[0003] In existing tapered roller bearings, the cage is designed as a single, enclosed structure, which makes it difficult to assemble on the outside of all the cylindrical rollers, resulting in inconvenience in assembling the cylindrical rollers and the cage. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a tapered roller bearing, including an inner ring and an outer ring. A cage with a semi-open design on one side is movably fitted on the outer side of the inner ring. A cylindrical roller located on the inner side of the outer side of the inner ring is placed on the inner side of the cage. A first retaining ring located on one side of the cage is engaged on the outer side of the inner ring. A pressure plate is provided on the outer side of the cage. A support plate engaged on the outer side of the pressure plate is movably fitted on the outer side of the inner ring. A second retaining ring located on one side of the support plate is fitted on the outer side of the pressure plate.

[0005] Preferably, the distance between the openings of the second retaining ring is less than the width of the pressure plate.

[0006] Preferably, a limiting boss is provided on the outer side of the pressure plate.

[0007] Preferably, the outer side of the support plate is provided with a slot that is compatible with the pressure plate.

[0008] The advantages of this utility model are as follows:

[0009] 1. This tapered roller bearing features a semi-open cage design. After the cage is fitted onto the outside of the inner ring, the opening of the cage can be pushed outward by a pressure plate. This facilitates the installation of the cylindrical rollers one by one between the inner ring and the cage. Furthermore, the cooperation between the pressure plate and the support plate allows the second retaining ring, fitted onto the outside of the pressure plate, to limit and fix the cage through a retaining groove. This structure makes the assembly of the cylindrical rollers and the cage relatively easy.

[0010] 2. The tapered roller bearing can limit and support the cage opening through the first retaining ring to prevent the cage from moving along the axial direction of the inner ring. Then, the pressure plate pushes the cage opening outward to facilitate the placement of the cylindrical roller between the inner ring and the cage. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0021] Please see Figure 1-6A tapered roller bearing includes an inner ring 1 and an outer ring 2. A cage 3 with a semi-open design on one side is movably fitted on the outer side of the inner ring 1. Cylindrical rollers 4 located on the inner side of the outer side of the inner ring 1 are placed on the inner side of the cage 3. The cage 3 can limit the movement of the cylindrical rollers 4, allowing multiple cylindrical rollers 4 to be placed on the outer side of the inner ring 1. A first retaining ring 5 located on one side of the cage 3 is engaged with the outer side of the inner ring 1. The first retaining ring 5 can limit and support the cage 3, preventing it from moving along the axial direction of the inner ring 1. Then, a pressure plate 6 can open the cage 3. The part is opened outward to facilitate the placement of the cylindrical rollers 4 one by one between the inner ring 1 and the cage 3. The cage 3 can be released by removing the first retaining ring 5. At this time, the cage 3 can be pushed and disassembled along the axial direction of the inner ring 1. A pressure plate 6 is provided on the outer side of the cage 3. A support plate 7 is movably sleeved on the outer side of the inner ring 1 and snapped onto the outer side of the pressure plate 6. A second retaining ring 8 is sleeved on the outer side of the pressure plate 6 and located on one side of the support plate 7. The pressure plate 6 can be pressed and fixed to the inner side of the support plate 7 by the second retaining ring 8, and the support plate 7 can ensure that the cage 3 is not easily bent.

[0022] The distance between the openings of the second retaining ring 8 is less than the width of the pressure plate 6. This structure ensures that when the second retaining ring 8 deflects around its own axis, it can always be fitted onto the outside of the pressure plate 6, pressing all the pressure plates 6. Thus, the pressure plates 6 can be pressed and fixed onto the support plate 7 by the second retaining ring 8. Furthermore, by removing the second retaining ring 8, the restriction on the support plate 7 can be released, making it easy to disassemble and assemble the support plate 7.

[0023] Among them, the outer side of the pressure plate 6 is provided with a limiting boss 9. The limiting boss 9 enables the second retaining ring 8 to be fitted on the outer side of the pressure plate 6, thereby limiting the support plate 7 and enabling the support plate 7 to stably limit and support the cage 3.

[0024] The support plate 7 has a slot 10 on its outer side that is compatible with the pressure plate 6. The slot 10 can not only avoid the pressure plate 6, but also limit and support the pressure plate 6. After the second retaining ring 8 is fitted on the outer side of the pressure plate 6, it can press the pressure plate 6 to the inner side of the slot 10 and limit and support the cage 3, ensuring that the cage 3 can stably limit the cylindrical roller 4.

[0025] When assembling a tapered roller bearing, after the cage 3 is fitted onto the outside of the inner ring 1, the first retaining ring 5 is engaged on the outside of the inner ring 1. At this time, the first retaining ring 5 limits the cage 3. The pressure plate 6 opens the opening of the cage 3 outward. The cylindrical rollers 4 are placed one by one between the inner ring 1 and the cage 3. After all the cylindrical rollers 4 are placed, the support plate 7 is fitted onto the outside of the inner ring 1, and the pressure plate 6 is engaged on the inside of the retaining groove 10. The second retaining ring 8 is opened and fitted onto the outside of the pressure plate 6. At this time, the second retaining ring 8 is located between the support plate 7 and the limiting boss 9. The pressure plate 6 is pressed tightly on the inside of the retaining groove 10 by the second retaining ring 8. Finally, the outer ring 2 is fitted onto the outside of the inner ring 1, completing the assembly of the tapered roller bearing. The contents not described in detail in this description are prior art known to those skilled in the art.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
