Description

Technical Field

[0001] This utility model relates to the field of bearing design, and in particular to a noise-reducing oil-impregnated bearing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] With the continuous improvement of technology, people's requirements for environmental comfort are also increasing. Existing bearing products include rolling bearings and sliding bearings. In products such as baby hair clippers and pet grooming clippers, the bearings installed inside are mostly rolling bearings, including inner rings, outer rings and balls. When they rotate, they produce a lot of noise. Moreover, the manufacturing cost of this type of bearing is high, it is difficult to repair when damaged, and the noise will have a great impact on the use of the product.

[0004] Most sliding bearings on the market do not have an oil storage function. They have a high coefficient of sliding friction, which can cause noise. Excessive friction can also seriously affect the service life of the product.

[0005] Therefore, it is necessary to design a low-noise, oil-impregnated sliding bearing to solve the problems of excessive noise, high manufacturing cost, and short service life of existing bearing products. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0007] A noise-reducing oil-impregnated bearing includes a sliding bearing body, wherein an inner circular hole is integrally formed in the middle of the sliding bearing body, and a flared opening that is narrower at the top and wider at the bottom of the inner circular hole is integrally formed.

[0008] A spherical body is integrally formed on the outer side of the upper end of the sliding bearing body, and the center of the spherical body is located at the axis of the inner circular hole. A positioning ring is integrally formed on the bottom end of the outer side of the sliding bearing body, and the positioning ring is located on the bottom side of the spherical body.

[0009] Furthermore, the height of the positioning ring is the same as the height of the horn opening.

[0010] Furthermore: a rotating shaft is rotatably installed in the inner circular hole, a base is integrally formed at the bottom end of the rotating shaft, an oil storage tank is integrally formed on the base, and the positioning ring is rotatably installed in the oil storage tank.

[0011] Furthermore, a stepped groove is integrally formed between the lower end of the sphere and the positioning ring, and both the stepped groove and the positioning ring are fitted into the oil storage tank.

[0012] Furthermore: the oil storage tank contains lubricating oil, which seeps into the flared opening.

[0013] Furthermore: a first chamfer is integrally formed between the upper end of the inner circular hole and the sliding bearing body; a second chamfer is integrally formed between the bottom end of the flared opening and the sliding bearing body; and a third chamfer is integrally formed at the bottom edge of the outer side of the sliding bearing body.

[0014] Furthermore, the top side of the sliding bearing body is a plane, and the plane cuts through the upper end of the sphere.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. A flared opening is provided at the bottom of the inner hole to facilitate the installation of the sliding bearing body on the rotating shaft;

[0017] 2. A positioning ring is set at the bottom of the outer side of the sliding bearing body, which facilitates the precise installation of the sliding bearing body into the assembly position. Before installation, lubricating oil is applied to the assembly position and the inner hole. After installation, the lubricating oil will seep into the flared position to achieve a full lubrication effect, reduce noise generation, and also reduce friction when the sliding bearing rotates, making it smoother.

[0018] This invention can be applied to products such as baby hair clippers and pet grooming clippers, achieving a silent rotation effect.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1-4 As shown, a noise-reducing oil-impregnated bearing of the present invention includes a sliding bearing body 1, wherein an inner circular hole 2 is integrally formed in the middle of the sliding bearing body 1, and a flared mouth 3 that is narrow at the top and wide at the bottom of the inner circular hole 2 is integrally formed.

[0032] A spherical body 4 is integrally formed on the outer side of the upper end of the sliding bearing body 1. The center of the spherical body 4 is located at the axis of the inner circular hole 2. A positioning ring 5 is integrally formed on the bottom end of the outer side of the sliding bearing body 1. The positioning ring 5 is located on the bottom side of the spherical body 4.

[0033] The principle is as follows: a flared opening 3 is provided at the bottom of the inner hole 2 to facilitate the installation of the sliding bearing body 1 on the rotating shaft 6. In addition, a positioning ring 5 is provided at the bottom of the outer side of the sliding bearing body 1 to facilitate the precise installation of the sliding bearing body 1 into the assembly position. Before installation, lubricating oil is applied to the assembly position and the inner hole 2. After installation, the lubricating oil will seep into the flared opening 3 to achieve a full lubrication effect, reduce noise generation, and also reduce friction when the sliding bearing rotates, making it smoother. It can be used in baby series products such as hair clippers and pet series products such as fur trimmers to achieve a silent rotation effect.

[0034] Furthermore, the height of the positioning ring 5 is the same as the height of the flared mouth 3, which allows the lubricating oil to be fully filled into the flared mouth 3, ensuring the lubrication effect.

[0035] Furthermore: a rotating shaft 6 is rotatably installed in the inner circular hole 2, and a base 7 is integrally formed at the bottom end of the rotating shaft 6. An oil reservoir 8 is integrally formed on the base 7, and the positioning ring 5 is rotatably installed in the oil reservoir 8. Since the height of the oil reservoir 8 and the height of the positioning ring 5 are matched, and the oil reservoir 8 can stably hold lubricating oil, the lubricating oil can also fully penetrate into the flared mouth 3, thus achieving sufficient lubrication between the rotating shaft 6 and the inner circular hole 2, and reducing the occurrence of oil leakage.

[0036] Furthermore, a stepped groove 9 is integrally formed between the lower end of the spherical body 4 and the positioning ring 5. The stepped groove 9 and the positioning ring 5 are both installed in the oil storage tank 8. The stepped groove 9 allows the positioning ring 5 to be installed more stably in the oil storage tank 8, resulting in higher installation accuracy and reducing the likelihood of oil leakage.

[0037] Furthermore, the oil storage tank 8 stores lubricating oil, which seeps into the flared opening 3.

[0038] Furthermore: a first chamfer 10 is integrally formed between the upper end of the inner circular hole 2 and the sliding bearing body 1; a second chamfer 11 is integrally formed between the bottom end of the flared mouth 3 and the sliding bearing body 1; and a third chamfer 12 is integrally formed at the bottom edge of the outer side of the sliding bearing body 1. The chamfers make the sliding bearing body 1 more rounded, preventing it from contacting surrounding components during high-speed rotation, thus ensuring stable rotation and reducing the risk of damage during mass transportation.

[0039] Furthermore, the top side of the sliding bearing body 1 is a plane 13, which cuts open the upper end of the sphere 4; this ensures the stable installation of the sliding bearing body 1.

[0040] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
