Description

Technical Field

[0001] This utility model relates to the field of transmission components technology, and in particular to a lubricated and noise-reducing gear. Background Technology

[0002] Gears are mechanical components used to transmit power and change the speed and direction of motion, and are widely used in various mechanical equipment. They achieve efficient power transmission through the meshing of teeth, and are characterized by their compact structure, high transmission efficiency, and high precision. There are many types of gears, including spur gears, helical gears, bevel gears, and worm gears, each suitable for different applications. Gears are typically made of steel, cast iron, or plastic, and their design and manufacturing precision directly affect transmission efficiency and service life. High-quality gears provide efficient power transmission, low noise, and long lifespan, making them indispensable key components in modern mechanical transmission systems.

[0003] However, current gears require continuous lubrication during transmission. Due to the rotation of the gears, the lubricating oil gradually comes off the gears under the action of centrifugal force, which leads to a significant decrease in the lubrication effect of the gears. At the same time, the lack of lubrication will cause friction and noise during transmission.

[0004] Therefore, a lubricated and noise-reducing gear is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lubricated and noise-reducing gear.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lubricated noise-reducing gear includes a gear ring and a plurality of teeth fixedly connected to the outer ring of the gear ring. An oil storage ring groove is provided inside the gear ring. Holes communicating with the oil storage ring groove are provided on the outer ring of the gear ring between adjacent teeth. A sponge connecting strip is fixedly connected to the gear ring between adjacent teeth, and the sponge connecting strip covers the opening of the hole.

[0008] Preferably, the hole includes an outer constriction hole communicating with the oil storage annular groove and an inner constriction hole communicating with the outside, wherein the smallest ends of the outer constriction hole and the inner constriction hole are interconnected.

[0009] Preferably, the inner ring of the gear ring is fixedly connected with a plurality of evenly spaced inner protrusions.

[0010] Preferably, the inner ring of the gear ring has an inlet hole that communicates with the inner ring of the oil reservoir groove, and a plug is detachably connected to the inlet hole.

[0011] Preferably, the inner wall of the inlet hole is provided with an internal thread, and the outer ring of the plug is provided with an external thread. The plug is threadedly connected to the inlet hole through the external and internal threads.

[0012] Preferably, it also includes two sets of semi-circular sponge strips, each set of the semi-circular sponge strips including two semi-circular sponge strips, and several sponge connecting strips are fixedly connected between the two semi-circular sponge strips in the same set.

[0013] This utility model has the following beneficial effects:

[0014] In application of this invention, the operator introduces lubricating oil into the oil reservoir groove through the inlet hole, and then seals the inlet hole with a plug. When the gear is mounted on the gear shaft and is working, the lubricating oil diffuses outward through the outer contraction hole under centrifugal force, and a small amount of lubricating oil enters the inner contraction hole and diffuses onto the sponge connecting strip. When other gears mesh, they squeeze the sponge connecting strip, causing the lubricating oil to adhere to the gear surface, reducing wear and noise. Attached Figure Description

[0027] A type of lubricated and noise-reducing gear, such as Figures 1 to 4As shown, the device includes a gear ring 1 and several teeth 8 fixedly connected to the outer ring of the gear ring 1. Several evenly spaced inner protrusions 2 are fixedly connected to the inner ring of the gear ring 1. An oil storage ring groove 5 is opened inside the gear ring 1. Holes communicating with the oil storage ring groove 5 are opened on the outer ring of the gear ring 1 between adjacent teeth 8. The holes include an outer shrinkage hole 6 communicating with the oil storage ring groove 5 and an inner shrinkage hole 7 communicating with the outside. The smallest ends of the outer shrinkage hole 6 and the inner shrinkage hole 7 are connected to each other. A sponge connecting strip 10 is fixedly connected to the gear ring 1 between adjacent teeth 8. The sponge connecting strip 10 covers the opening of the hole. The device also includes two sets of semi-circular sponge strips 9. Each set of semi-circular sponge strips 9 includes two semi-circular sponge strips 9. Several sponge connecting strips 10 are fixedly connected between the two semi-circular sponge strips 9 in the same set.

[0028] The inner ring of the gear ring 1 has an inlet hole 4 that communicates with the inner ring of the oil reservoir groove 5. A plug is detachably connected to the inlet hole 4. The inner wall of the inlet hole 4 has an internal thread, and the outer ring of the plug has an external thread. The plug is connected to the inlet hole 4 by the external thread and the internal thread.

[0029] In practical application, the operator introduces lubricating oil into the oil storage ring groove 5 through the inlet hole 4, and then rotates the plug so that the plug can enter the inlet hole 4 by engaging the internal and external threads, thereby completing the sealing of the inlet hole 4.

[0030] The gear can then be installed on the gear shaft for operation. During gear rotation, the lubricating oil in the oil storage ring groove 5 can diffuse outward through the outer shrinkage hole 6 under the centrifugal force of gear rotation. At the same time, due to the setting of the outer shrinkage hole 6, the amount of lubricating oil entering the inner shrinkage hole 7 can be kept to a small amount. Then, the lubricating oil entering the inner shrinkage hole 7 can diffuse onto the sponge connecting strip 10 under the influence of the inner wall of the gradually increasing diameter of the inner shrinkage hole 7. This allows the sponge connecting strip 10 to absorb a small amount of lubricating oil. During the meshing and transmission of the gear with other gears, the other gears are squeezed onto the sponge connecting strip 10, so that the surface of the other gears can be contaminated with lubricating oil. This allows the lubricating oil to adhere to the teeth 8 of the gear, ultimately reducing its wear and also reducing the noise generated during its transmission.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
