Description

Technical Field

[0001] The utility model belongs to the field of textile machinery, in particular to a bearing lubricating device and a transmission wheel structure. Background Art

[0002] Warp knitting machines involve various transmission structures. The drive pulley structure, a crucial rotating component, has a direct impact on the machine's overall transmission performance, operational stability, and equipment lifespan. Regular maintenance and inspections are essential. Manually added lubricant, through internal frictional heat, gradually softens and evenly distributes itself between the bearing raceways and rolling elements, ensuring the optimal working condition of the drive pulley and its associated components.

[0003] As a core component of the textile industry, efficient and stable operation of warp knitting machines is crucial for ensuring production efficiency, product quality, and meeting market demand. Due to the unique nature of their production process, warp knitting machines typically operate continuously for extended periods of time (commonly known in the industry as "non-stop operation") to maximize equipment capacity, minimize non-productive time, and ensure on-time order delivery. Existing bearing lubrication devices are mostly installed directly on the bearing seat or bearing body, requiring regular downtime for lubrication. This not only directly results in lost production time and impacts production schedules, but can also cause other associated equipment on the production line to shut down simultaneously, resulting in a decrease in overall production efficiency.

[0004] In addition, when adding lubricating grease, the synchronous belt needs to be disassembled, and even the entire synchronous shaft needs to be pulled out to add lubricating grease. After completing the lubricating grease operation, reassembly is not only complicated, time-consuming and labor-intensive, but also may affect the transmission accuracy of the synchronous transmission mechanism.

[0005] Therefore, it is urgent for those skilled in the art to design a bearing lubrication device that can add lubricating grease without stopping the machine. Utility Model Content

[0006] In order to overcome the above technical defects, the present invention provides a bearing lubrication device and a transmission wheel structure to solve the problems involved in the background technology.

[0007] The utility model provides a bearing lubrication device, comprising: a fixed shaft, a bearing seat arranged on the fixed shaft, an oil injection pipeline formed inside the fixed shaft and extending to the circumference of the bearing seat, a bearing rotatably mounted on the bearing seat, and an oil injection hole arranged on the inner surface of the bearing and connected to the oil injection pipeline.

[0008] Preferably or optionally, the oil injection pipe is arranged on the central axis of the fixed shaft and passes through at least one end of the fixed shaft to form a through hole.

[0009] Preferably or optionally, a plug is provided on the through hole.

[0010] Preferably or optionally, the through hole is sealed and connected with an oil injection needle.

[0011] Preferably or optionally, the bearing seat is eccentrically arranged on the fixed shaft.

[0012] Preferably or optionally, both ends of the fixed shaft are respectively mounted on mounting holes of two side plates of the mounting seat, and are rotated at a predetermined angle relative to the mounting holes.

[0013] Preferably or optionally, a limit member is further provided on the mounting seat, suitable for limiting the free rotation of the fixed shaft.

[0014] Preferably or optionally, the limiting member includes: a gap portion formed on the mounting seat and extending to the fixed shaft mounting hole, and a fastening bolt inserted into the gap portion.

[0015] Preferably or optionally, the bearing seat and the fixed shaft are an integrated structure.

[0016] The utility model also provides a transmission wheel structure, comprising: the bearing lubrication device and a transmission wheel arranged on the bearing.

[0017] The utility model relates to a bearing lubrication device and a transmission wheel structure. Compared with the existing technology, the utility model has the following beneficial effects: the utility model provides an oil injection pipe inside the fixed shaft, and the oil injection pipe extends to the circumference of the bearing seat and is connected to the oil injection hole provided on the inner surface of the bearing. Since the position of the fixed shaft is in a stationary state, the warp knitting machine can add lubricating grease to the bearing when it is in a continuous operation state, which not only ensures the efficient operation of the equipment, but also reduces maintenance costs and improves the overall efficiency of the warp knitting machine.

DETAILED DESCRIPTION

[0022] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0023] See attached Figures 1 to 3 A bearing 400 lubrication device is mainly used in various transmission wheel 600 structures in warp knitting machines. The bearing 400 lubrication device includes: a fixed shaft 100, a bearing seat 200 arranged on the fixed shaft 100, an oil injection pipe 300 formed inside the fixed shaft 100 and extending to the circumference of the bearing seat 200, a bearing 400 rotatably mounted on the bearing seat 200, and an oil injection hole 410 arranged on the inner surface of the bearing 400 and connected to the oil injection pipe 300.

[0024] In this example, an oil filling pipe 300 is provided inside the fixed shaft 100 and extends to the circumference of the bearing seat 200, and is connected to the oil filling hole 410 provided on the inner surface of the bearing 400. Since the position of the fixed shaft 100 is in a stationary state, the warp knitting machine can add lubricating grease to the bearing 400 during continuous operation, which not only ensures the efficient operation of the equipment, but also reduces maintenance costs and improves the overall efficiency of the warp knitting machine.

[0025] In a further embodiment, the oil injection conduit 300 is disposed on the central axis of the fixed shaft 100 and extends through at least one end of the fixed shaft 100 to form a through hole 310. In this embodiment, the oil injection conduit 300 extends through both ends of the fixed shaft 100 to form two through holes 310. Under normal operating conditions, to ensure the sealing of the interior of the fixed shaft 100 and prevent the intrusion of external impurities or accidental leakage of grease, a plug 311 is provided on the through hole 310. The plug 311 is typically made of a wear-resistant, pressure-resistant material with good sealing properties, such as metal, engineering plastic, or rubber. The plug 311 is tightly connected to the through hole 310 through a detachable method such as threading, snapping, or pressing, allowing for quick and easy removal. When lubricating grease is required, the plug 311 is removed, and the oil injection needle is sealedly connected to the through hole 310 to oil the bearing 400. After the oil injection is completed, the oil injection needle is removed and the plug 311 is reinstalled.

[0026] In a further embodiment, the bearing seat 200 is eccentrically mounted on the fixed shaft 100, with both ends of the fixed shaft 100 mounted on mounting holes 511 of the two side plates 510 of the mounting seat 500. Prior to installation, the fixed seat 200 can be rotated relative to the mounting holes 511 by a predetermined angle to adjust the position of the bearing seat 200 and the synchronous pulley, thereby tensioning the synchronous belt and ensuring the transmission stability and accuracy of the transmission mechanism composed of the transmission pulley 600 and the synchronous pulley. To ensure that the fixed shaft 100 remains stable and does not rotate unnecessarily after position adjustment, a limit member is further provided on the mounting seat 500 to limit the free rotation of the fixed shaft 100. Specifically, the limit member includes a gap portion 512 formed on the mounting seat 500 and extending to the mounting hole 511 of the fixed shaft 100, and a fastening bolt inserted into the gap portion 512. The gap of the gap portion 512 is adjusted by tightening the bolts, so that the mounting hole 511 and the fixed shaft 100 are in close contact or appropriately squeezed, thereby achieving fixation of the fixed shaft 100 .

[0027] In a further embodiment, the bearing seat 200 and the fixed shaft 100 are an integrated structure, which enhances the connection strength and structural stability between components, simplifies the assembly process, improves equipment efficiency and reliability, and optimizes the overall performance and durability of the equipment.

[0028] In order to facilitate understanding of the technical solution of the bearing 400 lubrication device, a brief description is given of its working principle: to maintain the normal operation of the transmission structure, when lubricating grease needs to be added, the plug 311 is removed, the oiling needle is sealed and connected to the through hole 310, and the bearing 400 is oiled. After the oiling is completed, the oiling needle is removed and the plug 311 is reinstalled, so that the warp knitting machine can add lubricating grease to the bearing 400 in a continuous operation state, which not only ensures the efficient operation of the equipment, but also reduces maintenance costs and improves the overall efficiency of the warp knitting machine.

[0029] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.
