Description

Technical Field

[0001] This utility model relates to the field of braiding machine technology, specifically to a planar oil-storage friction-reducing braiding machine rotor structure. Background Technology

[0002] Braiding machines, as essential machinery for fabric production, are widely used in the textile industry. Circular braiding machines, in particular, are used for weaving packaged fabrics. During operation, the warp yarns cross and open under the action of the heddle frame, while the weft shuttle moves in a circular motion through the warp yarns to complete the weaving. Currently available circular braiding machines with 16-1000 spindles mostly employ a structure where a rotating gear assembly drives a rotating disc rotor. The disc rotor has notches on its surface housing spindle seats, on which the raw yarn spindles are mounted. However, in actual operation, the disc rotor moves the spindle seats through U-shaped grooves, and prolonged friction from this movement generates a significant amount of heat. This not only affects the mechanical properties of the disc rotor and shortens its service life but may also lead to the evaporation and deterioration of the lubricating oil, further exacerbating friction and reducing the braiding machine's efficiency and weaving quality. Therefore, developing a braiding machine rotor structure that can effectively reduce friction and heat generation is of significant practical importance. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes a planar oil-storage friction-reducing braiding machine rotor structure, which can effectively reduce friction and lower heat.

[0004] The technical solution of this utility model: This utility model provides a planar oil-storage friction-reducing rotor structure for a braiding machine, including a rotor body, several oil-storage recesses, and concave grooves. The rotor body is disc-shaped with a mounting hole in the center for easy connection and fixation with other components of the braiding machine. Several oil-storage recesses are designed on both axial sides of the rotor body. These recesses can store lubricating oil and provide continuous lubrication to the contact surfaces with other components during rotor operation, reducing friction. A concave groove is formed around the outer perimeter of the non-mounting contact surface of the mounting hole, and the oil-storage recesses are located outside the concave groove. The concave groove design not only reduces the machining allowance in subsequent grinding processes and lowers production costs, but also allows for engraving markings in the recesses, facilitating product identification and management.

[0005] Further improvements: In some embodiments, the rotor body is provided with several U-shaped grooves around its circumference, and several oil-retaining dimples are designed on the outer sides of the axial openings of the U-shaped grooves, with these oil-retaining dimples distributed in an arc shape. This design further increases the number of oil-retaining dimples, improves the oil storage capacity, and the arc-shaped distribution of the oil-retaining dimples can better adapt to the circumferential motion of the rotor, allowing the lubricating oil to be more evenly distributed on the friction surface during rotor operation, further enhancing the friction reduction effect.

[0006] Material Selection: The braiding machine rotor is integrally molded using oil-impregnated powder metallurgy. The pores within the oil-impregnated powder metallurgy material can store lubricating oil, achieving a self-lubricating function for the rotor. The oil-impregnated powder metallurgy material itself possesses excellent self-lubricating properties; during the pressing process, the lubricating oil is sealed within the material's internal pores. During rotor operation, with the increase in temperature and the action of friction, the lubricating oil in the pores gradually seeps out, providing lubrication to various friction points of the rotor. This reduces reliance on external lubrication systems, lowers maintenance costs, and simultaneously improves the reliability of the braiding machine. Beneficial effects

[0007] Significant friction reduction effect: By setting oil storage pits on both axial sides of the rotor body and on the outer side of the U-shaped groove, combined with oil-impregnated powder metallurgy materials, sufficient lubricating oil can be provided to the rotor's friction surfaces, effectively reducing the coefficient of friction, reducing the heat generated by friction, and improving the rotor's service life and the working efficiency of the braiding machine. Tests show that, under the same working conditions, the rotor structure of this invention reduces the coefficient of friction by [X]% compared to the traditional rotor structure, and significantly lowers the rotor's operating temperature.

[0008] Cost reduction: The concave groove design reduces the machining allowance in subsequent grinding processes, thus lowering processing costs. Simultaneously, the self-lubricating properties of oil-impregnated powder metallurgy materials reduce reliance on external lubrication systems, simplifying the lubrication structure of the braiding machine and lowering equipment manufacturing and maintenance costs.

[0009] Easy to mark: Markings can be engraved on the bottom of the concave groove, which facilitates product identification, management and quality traceability, and improves the efficiency of production management. Attached Figure Description

[0013] See attached document Figure 1-3A planar oil-storage friction-reducing braiding machine rotor structure is characterized by comprising a rotor body 1, a plurality of oil-storage recesses 2, and a concave groove 3; the rotor body 1 is disc-shaped, and a mounting hole for connecting with braiding machine components is provided in the middle of the rotor body 1; a plurality of oil-storage recesses 2 are distributed on the axial two-sided plane of the rotor body 1, and the oil-storage recesses 2 are used to store lubricating oil to reduce friction during rotor operation; the concave groove 3 is formed by recesses around the non-mounting contact surface around the opening of the mounting hole, and the plurality of oil-storage recesses 2 are all located on the outside of the concave groove 3.

[0014] The rotor body 1 has several U-shaped grooves 4 spaced circumferentially on its circumferential sidewalls. The U-shaped grooves 4 are used to move the spindle seat of the braiding machine. Several oil storage recesses 2 are designed on the outer sidewalls of the axial openings of the U-shaped grooves 4, and the oil storage recesses 2 on both sides of the same U-shaped groove 4 are distributed in an arc shape along the circumferential direction of the rotor body 1.

[0015] The bottom surface of the concave groove 3 is engraved with a mark 31 for product identification, model labeling, or production information traceability.

[0016] The rotor body 1, oil storage recess 2, and concave groove 3 are made of oil-impregnated powder metallurgy material through an integrated pressing process. The pores inside the oil-impregnated powder metallurgy material can store lubricating oil, thereby realizing the self-lubricating function of the rotor.

[0017] Manufacturing Process: In manufacturing the rotor of this braiding machine, oil-impregnated powder metallurgy material is first used, and then integrally pressed using a mold. During the pressing process, the dimensional accuracy of the mold and the pressing pressure are strictly controlled to ensure that the shape and size of the rotor body meet the design requirements, while also ensuring the forming quality of structures such as oil storage recesses, concave grooves, and U-grooves. After pressing, the rotor undergoes appropriate post-processing, such as sintering and shaping, to improve the rotor's density and mechanical properties.

[0018] Installation and Use: Install the manufactured braiding machine rotor into the corresponding position on the braiding machine through the central mounting hole, ensuring a secure installation. Before running the braiding machine, add an appropriate amount of lubricating oil to the oil reservoir and U-groove. After starting the braiding machine, the rotor will begin to rotate. During operation, the lubricating oil stored in the oil reservoir will be gradually released under friction, providing lubrication to the contact surfaces of the rotor and other components such as the spindle seat, reducing friction and heat generation. Simultaneously, the lubricating oil inside the oil-impregnated powder metallurgy material will continuously seep out, replenishing lubrication.

[0019] Maintenance: During daily use of the braiding machine, regularly check the oil level in the rotor. If the amount of lubricating oil in the oil reservoir is insufficient, replenish it promptly. Also, observe the rotor surface for signs of wear. If slight wear is present, repair and maintain the worn areas appropriately. Regularly clean dust and impurities from the rotor surface to prevent them from entering the oil reservoir and U-groove, which could affect oil storage and lubrication.
