[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] In the description of the utility model, it should be explained that the orientation or position relationship of "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0025] A high-speed warp knitting machine swing arm joint connecting assembly, as shown in Figures 1-5 Fig. 1, comprising a bearing sleeve 1 and a plurality of needle rollers 2, steel sleeves 3 and connecting pin shafts 4 fixedly connected with the steel sleeves 3 arranged in the inner cavity of the bearing sleeve 1; the cavity of the bearing sleeve 1 comprises oil storage areas on both sides, and the outer wall of the bearing sleeve 1 is provided with an oil injection hole 1-4 penetrating the area of the needle roller 2.

[0026] Specifically, the design of the bearing sleeve 1 includes oil storage areas on both sides of the cavity, which can effectively store lubricating grease and ensure that the needle roller 2 is always fully lubricated during long-term and high-speed operation, reducing wear and failure caused by insufficient lubrication, improving the stability and service life of the equipment, reducing the loss and waste of lubricating grease, and reducing maintenance costs caused by poor lubrication. The outer wall of the bearing sleeve 1 is provided with an oil injection hole 1-4 that penetrates the area of the needle roller 2, making it easier to add and replenish lubricating grease. Users can directly inject lubricating grease into the oil storage area through the oil injection hole, without the need to disassemble the entire connecting piece, improving maintenance efficiency. The design of the entire connecting piece is compact, with tight cooperation between components, reducing failure and wear caused by looseness or excessive clearance, improving the overall rigidity and stability of the equipment, making the connecting piece more reliable and safe during high-speed operation.

[0027] As a preferred embodiment of the above, as shown in Figures 1-5 The oil storage areas on both sides of the cavity of the bearing sleeve 1 are provided with an oil storage sharp groove area 1-1, an oil storage flat groove area 1-2, and an oil storage circular groove area 1-3.

[0028] Specifically, by using different shapes of oil storage grooves, i.e., the oil storage sharp groove area 1-1, the oil storage flat groove area 1-2, and the oil storage circular groove area 1-3, lubricating grease can be more effectively stored and distributed, ensuring more uniform distribution of lubricating grease in the bearing sleeve cavity, reducing the problem of insufficient lubrication caused by uneven distribution of grease. The diversity of oil storage groove distribution improves the storage efficiency and utilization rate of lubricating grease, allowing the connecting piece to maintain good lubrication during long-term and high-speed operation. Different shapes of oil storage grooves can be adjusted and optimized according to actual use requirements and working environment. Due to the rationality and diversity of the oil storage groove design, lubricating grease can more effectively cover and lubricate the contact surface between the needle roller and the bearing sleeve, reducing failure and damage caused by friction and wear, prolonging the service life of the connecting piece. Optimizing the oil storage groove improves the lubrication effect and wear resistance of the connecting piece, reducing maintenance and use costs caused by poor lubrication, and allowing users to more easily check and observe the state and quantity of lubricating grease to discover and replenish lubricating grease in a timely manner, preventing poor lubrication caused by insufficient grease.

[0029] As a preferred embodiment of the above, as shown in Figures 1-5 There is a gap 1-1-1 between the oil storage sharp groove area 1-1 and the outer diameter of the steel sleeve 3.

[0030] As a preferred embodiment of the above, as shown in Figures 1-5 The gap 1-1-1 is between 0.05-0.15mm and cooperates with the rotation of the bearing sleeve 1 on the connecting pin shaft 4.

[0031] Specifically, by precisely controlling the range of gap 1-1-1 to be between 0.05-0.15mm, the flexibility and stability of bearing shell 1 when rotating on connecting pin shaft 4 are ensured, both preventing excessive shaking and instability due to a too large gap, and avoiding excessive friction and wear due to a too small gap, the presence of gap 1-1-1 allows lubricating grease to flow and distribute more freely between bearing shell 1 and steel shell 3, thus ensuring that lubricating grease can uniformly cover the contact surface between the needle roller and the bearing shell, thereby improving the lubrication effect.

[0032] As a preferred embodiment of the above, as shown in Figures 1-5 The outer wall of bearing shell 1 is provided with more than six oil injection holes 1-4 that penetrate the area of needle roller 2.

[0033] Specifically, the design of multiple oil injection holes 1-4 makes the addition and replenishment of lubricating grease more efficient and convenient, users can easily inject grease through any oil injection hole without worrying about insufficient lubrication or grease waste due to improper oil injection hole position. This reduces maintenance difficulty and cost, improves the reliability and stability of the equipment, and enhances the adaptability of the equipment to different working environments and use conditions. No matter what angle or position the equipment is in, users can always find a suitable oil injection hole for lubrication operation to ensure that the equipment always maintains good lubrication.

[0034] As a preferred embodiment of the above, as shown in Figures 1-5 The inner cavity 1-5 of the two sides of bearing shell 1

[0035] There is a gap between cavity 1-5 and each needle roller 2.

[0036] Specifically, by designing a gap between the inner cavity 1-5 of the two sides of bearing shell 1 and each needle roller 2, the needle roller is allowed to roll more freely inside the bearing shell, reducing heat and wear caused by friction, not only improving the rotation accuracy and stability of the connecting piece, but also prolonging the service life of the needle roller and the bearing shell.

[0037] As a preferred embodiment of the above, as shown in Figures 1-5 The circumference of each needle roller 2 is tangent to the inner wall of bearing shell 1 and the outer wall of steel shell 3 for high-speed operation.

[0038] Specifically, by designing the circumference of needle roller 2 to be tangent to the inner wall of bearing shell 1 and the outer wall of steel shell 3, the stability and accuracy of the needle roller during operation are ensured, and the tangent cooperation reduces the gap change caused by friction and wear, improving the rotation accuracy and stability of the connecting piece, thereby achieving more efficient and accurate operation.

[0039] As the preferred embodiment of the above, as shown in Figures 1-5 The bolt counterbores 4-1 are arranged on the connecting pin shaft 4 on the left and right sides of the bearing sleeve 1.

[0040] As the preferred embodiment of the above, as shown in Figures 1-5 The steel sleeve 3 is arranged separately from the connecting pin shaft 4 and fixedly connected.

[0041] As the preferred embodiment of the above, as shown in Figures 1-5 The steel sleeve 3 is arranged integrally with the connecting pin shaft 4.

[0042] Specifically, the separate arrangement allows the steel sleeve 3 and the connecting pin shaft 4 to be made of different materials to adapt to different working environments and performance requirements, and allows the steel sleeve 3 and the connecting pin shaft 4 to be manufactured and processed separately and then combined through fixed connection, thereby improving the flexibility of manufacturing and assembly and reducing production costs, while the integral arrangement allows the steel sleeve 3 and the connecting pin shaft 4 to be a whole structure, thereby improving the structural strength and stability of the connecting piece, and the connecting piece is particularly suitable for application scenarios that bear high loads and impacts.

[0043] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
