Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a wear-resistant reducer. Background Art

[0002] Reducers are generally used for low-speed and high-torque transmission equipment. The purpose of reducing speed is achieved by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft of the electric motor, internal combustion engine or other high-speed power. With the continuous development of the reducer industry, the demand for the use of reducers is also increasing. However, since reducers need to be used for a long time, their internal components are prone to wear and reduce their service life, and the cost of use is high. Therefore, special wear-resistant reducers are needed to increase their service life.

[0003] The existing wear-resistant reducer still has some problems when in use. First, due to the mutual meshing transmission of the gears inside the reducer, it is easy to wear during long-term use. Traditional wear-resistant protection is mainly achieved by directly adding an anti-wear layer to the outside of the gear or manually adding lubricating oil for protection. This method of wear-resistant layer is also easy to wear after long-term use. Not only is the protective wear-resistant effect low, but the convenience of use is also low. The mutual meshing of the gears is also prone to noise, and the use environment is poor. Secondly, when adding lubricating oil to the existing wear-resistant reducer, the lubricating oil is constantly splashed everywhere due to the rotation of the gears, which brings inconvenience to the subsequent cleaning of the inside of the reducer, and also causes indiscriminate waste, reducing the use effect.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0028] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0029] A wear-resistant reducer provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings. Embodiment 1

[0030] Combination Figure 1-Figure 3 As shown, the utility model provides a wear-resistant reducer.

[0031] Specifically, it includes an installation casing 1, wherein a large gear 6 and a small gear 7 are installed inside the installation casing 1 in sequence and mesh with each other, and a protective wear-resistant component 5 is sleeved on the outer sides of the large gear 6 and the small gear 7, and the protective wear-resistant component 5 is respectively composed of a protective sleeve pad 501, a compression air bag 502, an installation squeeze gasket 503, a through hole 504, an adsorption hole 505 and an oil-absorbing cotton layer 506. An oil storage tank 10 is embedded in the top of the interior of the installation casing 1, and an oil leakage pipe 11 is installed through the bottom end of the oil storage tank 10. A plurality of fine leakage holes at the bottom of the oil leakage pipe 11 facilitate the slow dripping of lubricating oil and save time for manual feeding. The compression air bag 502 and the installation squeeze gasket 503 are evenly arranged on the inner side of the protective sleeve pad 501, and the through hole 504 is opened on the side where the installation squeeze gasket 503, the compression air bag 502 and the protective sleeve pad 501 abut each other, and the adsorption holes 505 are respectively opened on the compression air bag 502. On both sides, the through hole 504 is connected to the interior of the compressed air bag 502 through the adsorption hole 505, and the oil-absorbing cotton layer 506 is filled in the interior of the compressed air bag 502. Both sides of the compressed air bag 502 are connected with an installation squeeze gasket 503. The installation squeeze gasket 503 is mainly to facilitate the installation of the compressed air bag 502, and at the same time facilitate the subsequent force extrusion of the compressed air bag 502. The installation squeeze gasket 503 is connected to the inner wall of the protective sleeve 501, and the top of the oil storage tank 10 is located on the outside of the installation casing 1 and is embedded with a sealing plunger 4. The sealing plunger 4 is mainly used to seal the oil filling port of the oil storage tank 10. The large gear 6 is located below the oil leakage pipe 11. The use of the above-mentioned components makes the composition of the components in the protective wear-resistant assembly 5, and the components perform surface protection on the large gear 6 and the small gear 7 that are meshed with each other, which also makes the protection of the lubricating oil more convenient. At the same time, the shock-absorbing liquid of the structure reduces the generation of noise and improves the use environment. Embodiment 2

[0032] Combination Figure 2 and 3 As shown, based on the first embodiment,

[0033] Specifically, an oil-proof film 8 is laid on the inner wall of the mounting casing 1, an oil collection box 9 is slidably installed on the bottom of the mounting casing 1, and the front end of the oil collection box 9 is located on the outside of the mounting casing 1 and is connected to a sealed draw-out door 3. The sealed draw-out door 3 is mainly used to facilitate the extraction of the lubricating oil collected in the oil collection box 9 to the outside for subsequent use. The use of the above-mentioned components and the oil-absorbing cotton layer 506 in the first embodiment not only makes the use of the lubricating oil more sufficient, but also reduces the situation of splashing of the lubricating oil, and collects excess lubricating oil, thereby improving the convenience of subsequent cleaning, reducing waste, and improving the use effect.

[0034] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0035] Specifically, a mounting base 2 is installed at the bottom of the mounting housing 1, and the mounting base 2 is mainly used to facilitate the installation and fixation of the reducer as a whole. An axle 12 is installed in the middle of the large gear 6, and the axle 2 is mainly used to facilitate the connection with the external mechanism that needs to be reduced speed.

[0036] The working principle and use process of the utility model are as follows: first, before use, fill the oil storage tank 10 with lubricating oil. When the large gear 6 and the small gear 7 are meshed with each other for transmission, the oil leakage pipe 11 at the bottom of the oil storage tank 10 also intermittently drips lubricating oil and falls on the protective wear-resistant component 5 on the outside of the large gear 6. The oil-absorbing cotton layer 506 in the compressed air bag 502 formed by the compressed air bag 502 absorbs and stores the lubricating oil. Due to the mutual squeezing of the large gear 6 and the small gear 7, the compressed air bag 502 continuously squeezes out and absorbs the lubricating oil absorbed in the oil-absorbing cotton layer 506 through the adsorption hole 505 and the through hole 504, thereby lubricating and protecting the large gear 6 and the small gear 7. At the same time, the protective sleeve pad 501 and the compressed air bag 502 also have a certain shock-absorbing effect on the pressure of the mutual meshing of the gears, which not only improves the wear-resistant protection effect and the convenience of use, but also has the effect of shock absorption and noise reduction, and improves the use environment. Secondly, in the above-mentioned use process, after the lubricating oil is absorbed and stored by the oil-absorbing cotton layer 506, the meshing transmission of the large gear 6 and the small gear 7 can continuously squeeze out and absorb the lubricating oil into the oil-absorbing cotton layer 506, so that the splashing of lubricating oil during transmission is reduced, and the oil-proof film 8 and the oil accumulation box 9 also collect excess lubricating oil, which not only improves the convenience of subsequent cleaning, but also reduces waste and improves the overall use effect.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
