Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to a high-stability textile circular knitting machine disc. Background Art

[0002] When the large disc gear in the textile circular machine rotates, and the large disc gear ring rotates around the large disc body, a large amount of lubricating oil is needed to lubricate the needle disk on the upper part of the large disc gear ring. During operation, the lubricating oil will drip onto the end face of the large disc gear. The lubricating oil remaining on the surface of the gear for a long time will corrode the surface. It is also possible that if it is not guided in time, it will flow between the large disc gear ring and the large disc body, causing the lubricating oil quality between the gear ring and the body to deteriorate, affecting the normal use of the large disc and even the equipment.

[0003] In addition, the gear ring and the main body of the large plate are in direct contact during operation. If they are not lubricated, a lot of heat will be generated, and the service life of the equipment will definitely be reduced. However, the lubricating oil filled between the gear ring and the main body of the large plate will generate a certain buoyancy when the large plate gear is running at high speed, causing the gear to deflect and drift. Therefore, it is necessary to divert and guide the lubricating oil in the lubrication groove to prevent the generation of buoyancy, so as to ensure that the equipment can operate more stably and reliably.

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The present embodiment describes a high-stability textile circular machine disc, comprising a disc body 1 and a disc gear ring 2, wherein the disc gear ring 2 is pressed and fixed in the disc body 1 to form a disc gear, and at least two circles of circular grooves are provided in parallel along the circumference of the disc body 1, one circle of grooves is used as a lubrication groove 12, and the other circle of grooves is used as an oil return groove 11, the lubrication groove 12 is filled with lubricating oil that reduces the friction between the contact surface between the disc body 1 and the disc gear ring 2, a circle of circular oil guide grooves 21 is provided in the circumferential direction of the surface of the disc gear ring 2, and a plurality of drainage grooves 22 are provided on the disc gear ring 2 at the periphery of the oil guide groove 21, the front end of the drainage groove 22 is connected to the oil guide groove 21, and the rear end of the drainage groove 22 has an oil return hole 23 that penetrates the disc gear ring 2, and the oil return hole 23 is connected to the oil return groove 11 below.

[0033] Specifically, the plurality of drainage grooves 22 are evenly arranged along the circumference of the large plate gear ring 2. The drainage grooves 22 are strip-shaped grooves as a whole, and are naturally inclined from the front end to the rear end. The inclination angle of the drainage grooves 22 from the front end to the rear end is 5 to 10 degrees.

[0034] During specific operation, the large disc gear rotates, and the needle disc lubricating oil dripping or flowing down from the upper needle disc will first gather in the oil guide groove 21 on the surface of the large disc gear ring 2 under the action of centrifugal force, and then flow through the front end of the drainage groove 22 to the oil return hole 23 at its rear end, and then be discharged from the surface of the large disc gear ring 2 through the oil return hole 23, and return to the oil return groove 11 of the large disc body 1 at the lower end, and then be collected and processed centrally.

[0035] In addition, in order to effectively reduce the temperature of the needle plate lubricating oil falling on the surface of the large plate gear ring 2 and to dissipate the heat of the large plate gear itself, a plurality of heat dissipation holes 24 are evenly arranged on the surface of the large plate gear ring 2. The plurality of heat dissipation holes 24 are blind holes arranged in the oil guide groove 21, which can not only increase the volume of the oil guide groove 21, but also increase the heat dissipation area and improve the heat dissipation efficiency.

[0036] In a further embodiment, a plurality of oil-guiding wear-resistant sheets 3 are evenly fixed in the lubrication groove 12. The oil-guiding wear-resistant sheets 3 are arc-shaped as a whole, have fixed holes on the surface, and are provided with a diverter slope 31 for oil guidance on at least one end. Usually, the large plate gear ring 2 rotates counterclockwise on the surface of the large plate body 1. Therefore, from a counterclockwise direction, the end of the oil-guiding wear-resistant sheet 3 that first contacts the moving lubricating oil is the front end, and the other end is the rear end. The direction of the diverter slope 31 is discussed similarly. It can be understood that it is usually sufficient to set the diverter slope 31 at the front end of the oil-guiding wear-resistant sheet 3, so as to achieve the purpose of "splitting" the lubricating oil and diverting and guiding it. Whether to set the diverter slope 31 at the rear end can be selected according to user needs.

[0037] The rear end of the diverter slope 31 is smoothly connected to the upper surface of the oil guide wear plate 3, and the front end is located in the same plane as the lower surface of the oil guide wear plate 3. It should be noted here that the diverter slope 31 can be integrally formed with the oil guide wear plate 3, or can be a wedge-shaped block fixed to the oil guide wear plate 3 by fasteners or welding, which can be selected according to specific circumstances.

[0038] Furthermore, the curvature of the oil-guiding wear-resistant sheet 3 is adapted to the curvature of the position where the lubricating groove 12 is set, and the two curvatures are substantially equal. That is, when the oil-guiding wear-resistant sheet 3 is set in the lubricating groove 12, the curvature of the oil-guiding wear-resistant sheet 3 is substantially the same as the curvature of the lubricating groove 12 where the oil-guiding wear-resistant sheet 3 is located, so that while guiding the lubricating oil, the resistance to the lubricating oil can also be reduced, thereby reducing its power consumption.

[0039] The upper surface of the oil-guiding wear-resistant sheet 3 is also provided with at least one diverter groove 32 for oil guiding, and the number of diverter grooves 32 can be set according to specific circumstances. The diverter groove 32 is a smooth S-shape or an arc shape adapted to the oil-guiding wear-resistant sheet 3, and the two ends of the diverter groove 32 are respectively located at the front and rear ends of the oil-guiding wear-resistant sheet 3, and cross the front and rear of the oil-guiding wear-resistant sheet 3. When the large plate gear is running, after the diverter slope 31 breaks the lubricating oil, the lubricating oil can be effectively diverted and guided along the diverter groove 32, reducing the viscosity of the lubricating oil and the friction between the lubricating oil and the oil-guiding wear-resistant sheet 3, so as to achieve the purpose of energy saving and power saving.

[0040] A smooth groove communicating with the diverter groove 32 on the surface of the oil-guiding wear-resistant plate 3 is also provided on the diverter slope 31 , and the diverter slope 31 may be a wedge-shaped structure.

[0041] In summary, the high-stability textile circular knitting machine disc of this embodiment can gather, collect, guide and effectively remove the lubricating oil of the upper needle disc accumulated on the surface of the disc gear, and can effectively reduce the temperature of the lubricating oil of the needle disc and reduce its temperature impact on the disc gear. At the same time, the oil-guiding wear-resistant sheet used can divert and guide the lubricating oil in the lubrication groove between the disc gear ring and the disc body, and can disperse the gear lubricating oil when the disc gear runs at high speed, so as not to generate buoyancy, thereby ensuring the efficient and stable operation of the disc gear.

[0042] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
