Description

Technical Field

[0001] The utility model relates to the field of gear rings, and more specifically, to a noise-reducing gear ring. Background Art

[0002] A gear refers to a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. The application of gears in transmission appeared very early. At the end of the 19th century, the principle of generating cutting method and the successive emergence of special machine tools and tools for cutting teeth using this principle, with the development of production, the smooth operation of gears has been emphasized.

[0003] For example, the planetary gear ring disclosed in the publication number CN218440493U belongs to the technical field of planetary gear accessories. The gear ring body includes splicing plates, teeth, a first limiting plate and a second limiting plate. The teeth, the first limiting plate and the second limiting plate are clamped on the surface of the splicing plate, and the teeth, the first limiting plate and the second limiting plate are all fastened to the surface of the splicing plate through fastening screws. The planetary gear ring is formed by splicing four arc-shaped splicing plates to form the gear ring body, and is fastened by the arc-shaped first limiting plate and the second limiting plate, having the function of disassembly and combination. It is not only convenient for the movement and carrying of the gear ring, but also convenient for the rapid assembly of the gear ring and the planetary gear, greatly improving its use convenience. And through the dovetail blocks and dovetail grooves provided on the teeth, each single tooth has the function of disassembly and combination, which is convenient for quickly replacing the damaged teeth separately in the later stage, greatly reducing the later maintenance cost of the gear ring.

[0004] As can be seen from the above disclosed solution, at present, due to the smooth front and back surfaces of the gear ring, it is not easy to store lubricating oil, and the lubricating oil will quickly flow away when flowing to the front and back surfaces of the gear ring. Without the lubrication of the lubricating oil, the friction force on the front and back surfaces of the gear ring will increase, and the large friction force will increase the noise generated when the gear ring rotates, failing to achieve the noise reduction effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a noise-reducing gear ring to solve the problem of lubrication and noise reduction of the gear ring.

[0006] To achieve the above object, the present utility model provides the following technical solution: A noise-reducing gear tooth ring, including a gear, the gear is provided with teeth, the gear is provided with a jack, the gear is provided with a card slot, the gear is provided with a plurality of internal weight-reducing holes, the gear is provided with a plurality of external weight-reducing holes, the front side of the gear is provided with a plurality of front strip-shaped grooves, the rear side of the gear is provided with a plurality of rear strip-shaped grooves, the front side of the gear is provided with a front annular groove, the rear side of the gear is provided with a rear annular groove, and oil-absorbing strips are respectively fixedly clamped inside the front strip-shaped grooves and the rear strip-shaped grooves, and annular strips are respectively fixedly clamped inside the front annular groove and the rear annular groove. Through the arrangement of the front strip-shaped grooves and the rear strip-shaped grooves, and the arrangement of the front annular groove and the rear annular groove, it is respectively convenient to clamp and limit the oil-absorbing strips and the annular strips at the front and rear of the gear. The lubricating oil will be absorbed and locked by the oil-absorbing strips and the annular strips for a long time, so that the lubricating oil slowly lubricates the front and rear of the gear respectively for a long time. The oil-absorbing strips and the annular strips are arranged separately, so that the lubricating oil is stored separately at the front and rear of the gear, thereby increasing the lubrication work on the front and rear of the gear, reducing the friction generated when the gear rotates, reducing the noise generated by friction, and achieving the effect of noise reduction.

[0007] Preferably, the inside of the jack is connected to the inside of the card slot, and the inner diameter of the internal weight-reducing hole is the same as that of the external weight-reducing hole.

[0008] Preferably, the front strip-shaped groove and the rear strip-shaped groove are of the same size, and the front annular groove and the rear annular groove are of the same size.
