Description

Technical Field

[0001] This utility model relates to a deep groove ball bearing for textile machinery. Background Technology

[0002] Ball bearings for textile machinery are mainly used in the oscillating devices of textile machinery, such as winding machines and looms. They need to withstand yarn tension or weft insertion resistance, as well as high-frequency impact loads, to maintain the stable and continuous delivery of yarn and ensure the stable operation of the textile machinery.

[0003] Due to structural design flaws, existing deep groove ball bearings suffer from low heat dissipation efficiency, which in turn affects the service life of the lubricating oil and sealing structure. Utility Model Content

[0004] The purpose of this utility model is to provide a technical solution for deep groove ball bearings for textile machinery that addresses the shortcomings of existing technologies. This solution not only improves the heat dissipation of deep groove ball bearings but also prevents lubricant leakage, thereby enhancing the stability of deep groove ball bearings and extending the service life of lubricant and seals.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A deep groove ball bearing for textile machinery, comprising:

[0007] The inner ring has a first rolling groove on its outer circumferential side.

[0008] The outer ring has a second rolling groove on its inner circumferential side.

[0009] A rolling element is tactilely connected between a first rolling groove and a second rolling groove;

[0010] and a cage, with each rolling element rotatably connected to the cage;

[0011] Its features are:

[0012] It also includes a heat dissipation mechanism, which includes heat dissipation holes and heat dissipation components. The heat dissipation holes are evenly distributed along the end face of the outer ring, and the heat dissipation components are connected to the cage. The heat dissipation components are embedded in the interior of the outer ring and communicate with the heat dissipation holes. Through the design of the above structure, not only is it beneficial to improve the heat dissipation effect of the deep groove ball bearing, but it also prevents lubricating oil leakage, improves the stability of the deep groove ball bearing, and can extend the service life of the lubricating oil and the seal ring.

[0013] Furthermore, the heat dissipation assembly includes a first heat dissipation ring, a second heat dissipation ring, a first heat dissipation fin, and a second heat dissipation fin. The first and second heat dissipation rings are distributed parallel to each other on both ends of the outer ring. The first and second heat dissipation rings are fixedly connected to each other by the first heat dissipation fin, which is fixedly connected to the outer circumferential side of the retainer. The second heat dissipation fin is located on the second heat dissipation ring on the opposite side of the first heat dissipation fin. Through the design of the first and second heat dissipation rings, the first heat dissipation fin, and the second heat dissipation fin, the heat between the inner and outer rings can be transferred to the heat dissipation holes for rapid heat dissipation, thereby improving heat dissipation efficiency without affecting the flow of lubricating oil.

[0014] Furthermore, a limiting groove is provided on the outer circumferential side of the cage, and the first heat sink is embedded in the limiting groove. The first heat sink is connected to the cage by fasteners passing through the first heat sink, thereby realizing the fixed connection between the first heat sink and the cage. This improves the connection strength and stability between the first heat sink ring, the second heat sink ring, the first heat sink and the cage, and avoids collisions between the first heat sink ring, the second heat sink ring and the rolling elements, which would affect the service life of the deep groove ball bearing.

[0015] Furthermore, the inner surface of the outer ring has a ring of fixing grooves that match the second heat sink. The second heat sink is fixed in the fixing groove and is connected to the heat dissipation hole, which facilitates the rapid conduction of heat away through the heat dissipation hole and improves the heat dissipation efficiency of the deep groove ball bearing.

[0016] Furthermore, it also includes a sealing mechanism, which includes a rubber sealing ring and a skeleton. The skeleton is located inside the rubber sealing ring. The rubber sealing ring is detachably connected to the outer ring and the inner ring. The skeleton can improve the strength and stability of the rubber sealing ring, thereby improving the sealing effect between the inner ring and the outer ring and preventing impurities from entering and affecting the normal use of the rolling elements.

[0017] Furthermore, a retaining strip is provided on the side of the rubber sealing ring near the outer ring, and a retaining groove is provided on the inner circumferential side of the outer ring. The retaining strip matches the retaining groove to improve the sealing effect.

[0018] Furthermore, the rubber sealing ring has a herringbone double lip structure, which fits against the outer circumferential side of the inner ring to improve the sealing effect.

[0019] Furthermore, the rubber sealing ring is made of nitrile rubber.

[0020] Furthermore, the frame is made of steel plates.

[0021] Furthermore, the cage is provided with uniformly spaced limiting holes in a ring shape, and the rolling elements are matched with the limiting holes.

[0022] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0023] 1. This utility model not only improves the heat dissipation effect of deep groove ball bearings, but also prevents lubricating oil leakage, thus improving the stability of deep groove ball bearings and extending the service life of lubricating oil and seals.

[0024] 2. Through the design of the first heat dissipation ring, the second heat dissipation ring, the first heat dissipation fin, and the second heat dissipation fin, the heat between the inner ring and the outer ring can be transferred to the heat dissipation hole for rapid heat dissipation, thereby improving heat dissipation efficiency without affecting the flow of lubricating oil.

[0033] like Figures 1 to 3 As shown, this utility model discloses a deep groove ball bearing for textile machinery, comprising: an inner ring 1, an outer ring 2, rolling elements 3, and a cage 4. The outer circumferential side of the inner ring 1 is provided with a first rolling groove, and the inner circumferential side of the outer ring 2 is provided with a second rolling groove. The rolling elements 3 are tactilely connected between the first rolling groove and the second rolling groove.

[0034] Each rolling element 3 is rotatably connected to a cage 4. The cage 4 has uniformly spaced, annular limiting holes 10, which the rolling elements 3 mate with. The rolling elements 3 can be steel balls.

[0035] The deep groove ball bearing also includes a heat dissipation mechanism, which includes heat dissipation holes 9 and heat dissipation components. The heat dissipation holes 9 are evenly distributed along the end face of the outer ring 2. The heat dissipation components are connected to the cage 4 and are embedded inside the outer ring 2 and connected to the heat dissipation holes 9.

[0036] The heat dissipation assembly includes a first heat dissipation ring 11, a second heat dissipation ring 12, a first heat dissipation fin 13, and a second heat dissipation fin 14. The first heat dissipation ring 11 and the second heat dissipation ring 12 are distributed in parallel on both ends of the outer ring 2. The first heat dissipation ring 11 and the second heat dissipation ring 12 are fixedly connected to each other by the first heat dissipation fin 13. The first heat dissipation fin 13 is fixedly connected to the outer circumferential side of the retainer 4. The second heat dissipation fin 14 is disposed on the second heat dissipation ring 12 and located on the opposite side of the first heat dissipation fin 13. Through the design of the first heat dissipation ring 11, the second heat dissipation ring 12, the first heat dissipation fin 13, and the second heat dissipation fin 14, the heat between the inner ring 1 and the outer ring 2 can be transferred to the heat dissipation hole 9, and the heat is quickly dissipated through the heat dissipation hole 9, thereby improving the heat dissipation efficiency without affecting the flow of lubricating oil.

[0037] The outer circumferential side of the cage 4 is provided with a limiting groove. The first heat sink 13 is embedded in the limiting groove and is connected to the cage 4 by fasteners passing through the first heat sink 13, thereby realizing the fixed connection between the first heat sink 13 and the cage 4. This improves the connection strength and stability between the first heat sink ring 11, the second heat sink ring 12, the first heat sink 13 and the cage 4, and avoids the first heat sink ring 11, the second heat sink ring 12 and the rolling element 3 from colliding, which would affect the service life of the deep groove ball bearing.

[0038] The inner side of the outer ring 2 has a ring of fixing grooves that match the second heat sink 14. The second heat sink 14 is fixed in the fixing groove and is connected to the heat dissipation hole 9, which facilitates the rapid conduction of heat away through the heat dissipation hole 9 and improves the heat dissipation efficiency of the deep groove ball bearing.

[0039] The above-mentioned structural design not only improves the heat dissipation of deep groove ball bearings, but also prevents lubricant leakage, thus improving the stability of deep groove ball bearings and extending the service life of lubricant and seals.

[0040] The deep groove ball bearing also includes a sealing mechanism, which includes a rubber seal ring 5 and a skeleton 6. The skeleton 6 is located inside the rubber seal ring 5. The rubber seal ring 5 is detachably connected to the outer ring 2 and the inner ring 1. The skeleton 6 can improve the strength and stability of the rubber seal ring 5, thereby improving the sealing effect between the inner ring 1 and the outer ring 2 and preventing impurities from entering and affecting the normal use of the rolling elements 3.

[0041] A retaining strip 7 is provided on the side of the rubber sealing ring 5 near the outer ring 2, and a retaining groove 8 is provided on the inner circumferential side of the outer ring 2. The retaining strip 7 matches the retaining groove 8 to improve the sealing effect.

[0042] The rubber sealing ring 5 features a herringbone double-lip structure, which fits snugly against the outer circumference of the inner ring 1 to improve the sealing effect. The rubber sealing ring 5 is made of nitrile rubber. The skeleton 6 is made of steel plate.

Any simple changes, equivalent substitutions, or modifications made based on this utility model to achieve essentially the same technical effect are all covered within the protection scope of this utility model.
