Description

Technical Field

[0001] The utility model belongs to the field of gear boxes and relates to bearing lubrication, in particular to an oil collecting and lubricating device for a gear box bearing. Background Art

[0002] Existing gearboxes that use splash lubrication during transmission often experience poor lubrication at locations higher than the oil sump. Bearings, in particular, often experience higher temperatures than other components, which reduces bearing life. To address this issue, additional lubrication lines are typically added to provide spray lubrication. However, this addition bloats the gearbox's internal structure, increasing assembly complexity and hindering production. Therefore, a new design is urgently needed to address this issue of poor lubrication at high-position bearings. Utility Model Content

[0003] In order to solve the above-mentioned problem of poor lubrication of high-position bearings, the utility model provides a structure in which oil liquid on the gear is scraped off and dripped onto the bearings.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a gearbox bearing oil collection and lubrication device, including an oil scraper arranged above the gear for scraping oil from the tooth surface, and the oil falls on both sides of the gear along the oil scraper.

[0005] Preferably, the oil scraper includes a first bend for scraping oil from the tooth top and a second bend for scraping oil from the tooth side.

[0006] Preferably, the top of the oil scraper is connected with a bolt for fixing the oil scraper.

[0007] Preferably, the second bend is arranged below the first bend.

[0008] Preferably, the oil collecting cup is further provided below the oil scraper.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] The utility model has the advantages of simple structure, easy manufacture and convenient assembly, and is suitable for popularization and application in production and processing.

[0011] The utility model does not rely on external structures, is simple and reliable, and has a low failure rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] In order to illustrate the usage of the present invention, the present invention discloses a gearbox, which is provided with a wheel disc 1 and a rotating shaft 4. The rotating shaft 4 is connected to a gear 2 and a bearing 3. The bearing 3 is located on the adjacent side of the gear 2 away from the wheel disc 1. The diameter of the gear 2 is larger than the diameter of the bearing 3. The bearing 3 is a high-position bearing and still adopts splash lubrication, that is, only the lower part of the gear 2 is partially immersed in the oil pool, and the bearing 3 cannot be immersed in the oil pool. As the gear 2 rotates, all teeth of the gear 2 are stained with lubricating oil.

[0019] like Figure 1 、 Figure 2 As shown, a gear 2 box bearing oil collection and lubrication device includes an oil scraper 5 arranged above the gear 2 for scraping oil from the tooth surface. The oil falls along the oil scraper 5 on both sides of the gear 2, that is, on the bearing 3, to achieve lubrication and cooling of the bearing 3.

[0020] Furthermore, the oil scraper 5 includes a first bend 51 for scraping oil from the tooth top and a second bend 52 for scraping oil from the tooth side. The tooth top and tooth side are the top surface and side surface of the teeth in the gear 2, and the second bend 52 is above the bearing 3.

[0021] Furthermore, the second bend 52 is disposed below the first bend 51. The oil scraped off by the first bend 51 flows to both sides and falls directly onto the second bend 52 on one side.

[0022] Furthermore, a bolt 6 for fixing the oil scraper 5 is connected to the top of the oil scraper 5, and the bolt 6 fixes the oil scraper 5 to the gear 2 box sheet metal.

[0023] Furthermore, the invention also includes an oil collecting cup 7 disposed below the side of the oil scraper 5. That is, the oil collecting cup can be disposed on either side of the oil scraper 5, or two oil collecting cups can be disposed on both sides of the oil scraper 5. In the accompanying drawings only, the present invention provides an oil collecting cup 7 that is easily machined. The oil collecting cup 7 includes a third bend 71. The third bend 71 is tilted. This tilting arrangement specifically means that under the influence of gravity, the oil flows along the third bend 71 in a direction away from the gear 2. The wheel disc 1 is correspondingly provided with an oil passage 11 for receiving the oil. The oil passes through the wheel disc 1 along this oil passage 11. Unlike the bearing 3 described above, the wheel disc 1 is also provided with a bearing on the side away from the gear 2. The oil passing through the oil passage 11 falls on the bearing on the side of the wheel disc 1 away from the gear 2.

[0024] In other embodiments, the oil collecting cup includes, but is not limited to, a conventional cylindrical cup, and an oil pipe is used to discharge the oil collected in the oil collecting cup. In other embodiments, those skilled in the art can easily infer that the second bend 52 can also be inclined by slanting the third bend 71 to better guide the flow of oil.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
