Abstract
Description
Technical Field
[0001] This utility model relates to a compressor bearing. Background Technology
[0002] Previously, compressor bearings used were only 4-7mm wide. The inner and outer rings of this type of bearing have small wall thicknesses. After the mandrel is pressed in and the housing is installed, the inner and outer rings are prone to large deformations, which affects the reliability of the structure and its service life. They require frequent maintenance and replacement, and the maintenance cycle is short. However, if the wall thickness is made thicker, it will be more difficult for the outer ring to deform, increasing the strength of the structure. But the number of steel balls that can be installed in the overall structure will be limited, resulting in insufficient load-bearing capacity. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a compressor bearing with a simple and reasonable structure that facilitates the installation of rollers while effectively improving structural strength and extending the service life of the structure.
[0004] To achieve the above objectives, this utility model provides a compressor bearing, including an outer ring and an inner ring, with a raceway formed between the outer ring and the inner ring. A cage is disposed in the raceway. An assembly notch is provided on the outer ring near the raceway. A plurality of pockets are evenly distributed on the cage. The width of the assembly notch is greater than the diameter of the pockets. A snap-fit block is also mounted on the assembly notch. The shape of the snap-fit block is the same as the shape of the assembly notch. A passage groove is provided on the snap-fit block corresponding to the position of the raceway.
[0005] The advantages of this design are as follows: When assembling the rollers, rotating the cage causes the pocket to align with the corresponding assembly notch, through which the roller is inserted. Rotating the cage then moves the next pocket to the next assembly notch, repeating this process to assemble the rollers. This allows for the assembly of a larger number of rollers, increasing the structure's load-bearing capacity. After assembly, the snap-fit block is engaged with the assembly notch to prevent the rollers from subsequently coming out, ensuring the structure's performance. Furthermore, since this bearing is used in structures such as compressors, the outer ring wall thickness can be increased to improve radial load-bearing capacity. Because it is used in compressors, where circumferential stress is relatively low, the snap-fit block structure does not affect structural strength, ensuring the structure's service life and resulting in excellent performance.
[0006] As a further feature of this invention, the snap-fit block is hollow and has a grease reservoir, which contains grease-retaining foam, and a grease application window is provided in the grease reservoir corresponding to the through groove.
[0007] The advantages of this setup are: it allows for efficient grease coating, resulting in good performance; it also makes good use of space, ensures structural stability, extends service life, and provides excellent overall performance.
[0008] As a further feature of this invention, the tail of the snap-fit block is provided with a replacement port for replacing the grease reservoir, and a cover is provided on the replacement port.
[0009] The advantages of this design are: it facilitates grease replacement, improves the efficiency of the structure, and is simple in structure, easy to implement, and has high replacement efficiency.
[0010] As a further feature of this invention, a soft-fitting abutment pad is provided on the snap-fit block corresponding to the position of the grease reservoir.
[0011] The advantages of this design are: it allows for manual or other trigger mechanisms to squeeze the grease when it is almost depleted, ensuring the lubrication effect of the structure. At the same time, the structure is simple, easy to implement, and has good performance.
[0012] As a further feature of this invention, the edge of the snap-fit block is provided with an arc-shaped groove.
[0013] The advantages of this design are: it facilitates the disassembly of the snap-fit block, and its simple structure makes it easy to implement and provides excellent performance. Attached Figure Description

[0017] This utility model provides an embodiment of a compressor bearing, such as... Figures 1 to 3As shown, it includes an outer ring 2 and an inner ring 1. A raceway 22 is formed between the outer ring 2 and the inner ring 1. A retainer 3 is provided in the raceway 22. An assembly notch 21 is provided on the side of the outer ring 2 near the raceway 22. A plurality of pockets 31 are evenly distributed on the retainer 3. The width of the assembly notch 21 is larger than the diameter of the pockets 31. A snap-fit block 4 is also fitted on the assembly notch 21. The shape of the snap-fit block 4 is the same as that of the assembly notch 21. A passage groove 42 is provided on the snap-fit block 4 corresponding to the position of the raceway 22. The advantages of this design are as follows: When assembling the rollers, rotating the retainer 3 causes the pocket 31 to move to the corresponding assembly notch 21, through which the roller is inserted into the pocket 31. Rotating the retainer 3 then moves the next pocket 31 to the corresponding position of the assembly notch 21, repeating this process to complete the roller assembly. This allows for the assembly of a larger number of rollers, increasing the load-bearing capacity of the structure. After assembly, the snap-fit block 4 is engaged with the assembly notch 21 to prevent the rollers from subsequently coming out, ensuring the structural performance. Furthermore, since this bearing is used in structures such as compressors, the outer ring 2 can be thickened to increase the radial load-bearing capacity. Because it is used in compressors, the circumferential stress is relatively small, and the snap-fit block 4 does not affect the structural strength, ensuring the structural service life and providing excellent performance.
[0018] As a further feature of this embodiment, the snap-fit block 4 is hollow and has a grease reservoir, which contains grease-retaining foam. A grease application window 43 is provided at the corresponding position of the through groove in the grease reservoir. The advantages of this design are: it allows for efficient grease application, resulting in good performance; it also makes reasonable use of space, ensures structural stability, and extends service life, thus providing excellent usability.
[0019] As a further feature of this embodiment, the tail of the snap-fit block 4 is provided with a replacement port for replacing the grease reservoir, and a cover 5 is provided on the replacement port. The advantages of this design are: it facilitates grease replacement, improves the efficiency of the structure, and is simple in structure, easy to implement, and has high replacement efficiency.
[0020] As a further feature of this embodiment, a softly designed abutment pad 41 is provided on the snap-fit block 4 corresponding to the position of the grease reservoir. The advantages of this design are: it allows for easy manual or other actuation mechanisms to squeeze the grease when it is nearly depleted, ensuring the lubrication effect of the structure; at the same time, the structure is simple, easy to implement, and has good performance.
[0021] As a further feature of this embodiment, the edge of the snap-fit block 4 is provided with an arc-shaped groove 44. The advantages of this feature are: it facilitates the disassembly of the snap-fit block 4, while also being simple in structure, easy to implement, and having good performance.
[0022] The above examples are merely one preferred embodiment of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution are all included within the protection scope of this utility model.
