Description
Technical Field
The utility model relates to the technical field of automobile parts, in particular to a novel needle bearing lubricating structure of a pure electric mining truck.
Background
At present, the problem that the needle bearing is difficult to oil inlet exists in the installation position of the gear shifting shaft of the pure electric mining truck, meanwhile, the needle bearing has a certain axial distance assembly requirement, and the common gasket cannot simultaneously meet the axial positioning and lubrication requirements.
Disclosure of Invention
Therefore, the utility model provides a novel needle bearing lubricating structure of a pure electric mining truck, which can overcome the defect of narrow space and difficult lubrication of a needle bearing mounting part of a gear shifting shaft in the prior art.
In order to solve the problems, the utility model provides a novel needle bearing lubricating structure of a pure electric mining truck, which comprises a gear shifting shaft, a lubricating gasket, a first gear shifting gear, a needle bearing and a second gear shifting gear, wherein the second gear shifting gear and the gear shifting shaft are integrally formed, the first gear shifting gear is sleeved on the gear shifting shaft, the needle bearing is arranged between the first gear shifting gear and the gear shifting shaft, the lubricating gasket is positioned between the first gear shifting gear and the second gear shifting gear, the lubricating gasket is of an annular structure, the end face of the lubricating gasket is provided with a first oil duct along the radial direction of the lubricating gasket, the inner wall of the lubricating gasket is provided with a second oil duct along the axial direction of the lubricating gasket, and gear oil enters the needle bearing along the first oil duct and the second oil duct so as to lubricate the needle bearing.
In some embodiments, the radial cross-sections of the first oil passage and the second oil passage are each circular arc segments.
According to the novel needle bearing lubricating structure of the pure electric mining truck, the first oil passage is formed in the end face of the lubricating gasket in the radial direction, and the second oil passage is formed in the inner wall of the lubricating gasket in the axial direction, so that gear oil is extruded into the needle bearing through the first oil passage and the second oil passage of the lubricating gasket under the meshing action of gears, the needle bearing at the gear shifting position is effectively lubricated, the axial positioning and lubricating requirements of the needle bearing at the gear shifting position of the pure electric mining truck can be met, the assembly is simple, and the production is easy.

The reference numerals are expressed as:
1. a shift gear shaft; 2. a lubrication pad; 3. a first gear; 4. needle roller bearings; 5. a radial oil passage; 6. an axial oil passage; 7. a second gear.
Detailed Description
Referring to fig. 1 to 2, according to an embodiment of the present utility model, a novel needle bearing lubrication structure of a pure electric mining truck is provided, including a gear shift shaft 1, a lubrication gasket 2, a first gear shift gear 3, a needle bearing 4 and a second gear shift gear 7, the second gear shift gear 7 is integrally formed with the gear shift shaft 1, the first gear shift gear 3 is sleeved on the gear shift shaft 1, the needle bearing 4 is arranged between the first gear shift gear 3 and the gear shift shaft 1, the lubrication gasket 2 is located between the first gear shift gear 3 and the second gear shift gear 7, the lubrication gasket 2 is in an annular structure, a first oil passage 5 is arranged on an end surface of the lubrication gasket 2 along a radial direction of the lubrication gasket, a second oil passage 6 is arranged on an inner wall of the lubrication gasket 2 along an axial direction of the lubrication gasket, and gear oil enters into the needle bearing 4 along the first oil passage 5 and the second oil passage 6 so as to lubricate the needle bearing 4.
In a specific embodiment, the radial sections of the first oil passage 5 and the second oil passage 6 are circular arc sections. The circular arc-shaped oil passage enables the resistance of the lubricating oil flowing in the oil passage to be minimum, is beneficial to the lubricating oil to smoothly reach the needle bearing 4, and has better lubricating effect.
Specifically, the radial section of the oil passage can also be rectangular, trapezoidal and the like. The oil ducts with different shapes can be designed according to the specific structures of different lubricating gaskets so as to meet the purpose of lubricating oil circulation.
Specifically, the first oil duct 5 is formed by a single end surface or a double end surface. The first oil passage 5 is formed according to the requirement of the lubricating oil quantity of the needle bearing 4, and when the first oil passage 5 is formed on both end surfaces, the lubricating oil is more favorable for flowing to the needle bearing 4.
Specifically, the first oil passage 5 and the second oil passage 6 are both distributed at equal intervals. The equidistant distribution can make the lubricating oil even respectively, makes the lubricating oil evenly distributed of needle bearing 4 department, better satisfies the lubrication demand of needle bearing 4.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model. The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
