A drive axle lubrication mechanism 100 according to a first aspect of the present utility model, as shown in fig. 1, the drive axle includes: a driving shaft 110, a sprocket 120 and a housing 130, wherein the driving shaft 110 is pivotally connected in the housing 130 through a bearing 160, the sprocket 120 is fixedly connected at one end of the driving shaft 110, a shaft cavity 131 and an oil cavity 132 are formed in the housing 130, a part of the driving shaft 110 is located in the shaft cavity 131, a part of the driving shaft 110 where the sprocket 120 is located in the oil cavity 132, and the lubrication mechanism 100 comprises:
the oil feeding device comprises an oil feeding channel 133 and an oil feeding part 140, wherein the oil feeding channel 133 is arranged on the shell 130 and is communicated with the oil cavity 132 and the shell 130, the oil feeding part 140 is fixed on the sprocket 120, and the oil feeding part 140 is configured to convey lubricating oil in the oil cavity 132 into the oil feeding channel 133, wherein the oil feeding channel 133 is positioned in a non-infiltration area of the oil cavity 132.
That is, during the operation of the drive axle, the driving shaft 110 drives the sprocket 120 to rotate in the housing 130, and the oil feeding portion 140 located on the sprocket 120 periodically rotates in the oil cavity 132 along with the sprocket 120, so as to drive the lubricating oil located in the oil cavity 132 to leave the soaking area of the oil cavity 132 and enter the shaft cavity 131 along the oil feeding channel 133, thereby lubricating the bearing 160 located in the shaft cavity 131, avoiding damage such as pitting of the bearing 160 and falling off of the retainer caused by impact load of the bearing 160, and greatly prolonging the service life of the bearing 160.
It should be noted that, a plurality of bearings 160 are disposed between the driving shaft 110 and the housing 130, for example, as shown in fig. 1, at least two ends of the driving shaft 110 located in the shaft cavity 131 are respectively disposed with bearings 160, wherein the bearings 160 near the oil cavity 132 are disposed with oil seals 170, so that lubricating oil cannot enter the shaft cavity 131.
In one example of the present utility model, the oil feeding part 140 is an oil box 141 and/or an oil scraper 142.
For the oil box 141, during the rotation of the sprocket 120, the oil in the oil cavity 132 is scooped up by the inner cavity, and then rotates to the non-wetting area along with the rotation of the sprocket 120, and the oil is poured to the oil inlet channel 133 along with the change of the angle of the sprocket 120 and in the non-wetting area, so that the oil box 141 is generally applied to the working condition of low-speed rotation of the sprocket 120;
for the oil scraping plate 142, during the rotation of the sprocket 120, the oil scraping plate 142 stirs the lubricating oil in the oil cavity 132, so that the lubricating oil splashes from the infiltration area to the non-infiltration area, and the lubricating oil is stirred and conveyed to the oil inlet channel 133, so that the oil scraping plate 142 is generally applied to the high-speed rotation of the sprocket 120.
In one example of the present utility model, the lubrication mechanism 100 further includes:
a drainage part 150 fixedly connected to the housing 130 and disposed near the oil inlet channel 133, and configured to drain the lubricating oil in the oil chamber 132 under the action of the oil box 141 or the oil scraper 142 into the oil inlet channel 133;
whether the oil box 141 or the oil scraping plate 142 is influenced by the structure of the oil box 141 and the position of the chain wheel 120 in the rotation process of the chain wheel 120, the lubricating oil can be conveyed in a directional or positioning way, and because the oil inlet channel 133 is arranged on the shell 130, the lubricating oil is difficult to be conveyed to the oil inlet channel 133 through the oil box 141 and/or the oil scraping plate 142 efficiently, and a transitional carrying drainage structure can be formed between the oil box 141 and/or the oil scraping plate 142 and the oil inlet channel 133 through the drainage part 150, so that the lubricating efficiency of the oil box 141 or the oil scraping plate 142 is greatly improved.
In one example of the present utility model, the drain 150 is an oil collector 151, and the oil collector 151 has at least one open end provided at an end side facing away from the driving shaft 110;
that is, the oil collector 151 can continuously accumulate the lubricating oil in the oil collector 151 during the operation of the oil tank 141 or the oil scraper 142, so that the oil inlet passage 133 can continuously lubricate the bearing 160 in the shaft cavity 131, thereby greatly improving the lubrication effect.
Of course, the present utility model is not limited thereto, and the drainage portion 150 may be a plate-like or groove-like drainage structure as long as the drainage function can be achieved.
In one example of the present utility model, the oil collector 151 extends from the housing 130 toward the sprocket 120 and is disposed at least opposite to the oil feeding portion 140 in a radial direction, so that the oil carried by the oil box 141 or the oil scraper 142 can be maximally transported into the oil collector 151, thereby greatly improving the working efficiency of the oil box 141 or the oil scraper 142; for example, by taking the oil catcher 151 as an example, the oil catcher 151 is extended to be close to the sprocket 120, and the oil box 141 is rotated to be in a non-wetting area, so that the oil can be completely faced to the opening of the oil catcher 151, and then the lubricating oil can be completely poured into the oil catcher 151.
In one example of the present utility model, the oil feed passage 133 extends obliquely downward from one end side of the communication oil chamber 132 to one end side of the shaft chamber 131; this ensures that the lubricant is able to flow under the force of gravity into the shaft cavity 131.
In one example of the present utility model, the oil box 141 and/or the oil scraper 142 is fixedly connected to the sprocket 120 at a position close to the teeth of the teeth;
the oil box 141 or the oil scraping plate 142 is disposed at a gear tooth position close to the sprocket 120, so that a certain space is reserved for the installation position of the oil collector 151, and meanwhile, the oil box 141 or the oil scraping plate 142 can rotate with a working radius as large as possible to convey lubricating oil, so that the conveying range of the lubricating oil is greatly improved.
In one example of the present utility model, when the oil container 141 and the oil scraper 142 are simultaneously provided on the sprocket 120, the oil scraper 142 is spaced apart from the oil container 141 along the circumferential direction of the sprocket 120; thus, the oil cartridge 141 and the oil scraper 142 do not affect each other, and are independent of each other.
In one example of the present utility model, the oil collector 151 is spaced from the central axis of the driving shaft 110 by a distance less than the central axes of the oil scraper 142 and the oil cartridge 141;
that is, the oil collector 151 is located within the working ranges of the oil scraping plate 142 and the oil box 141, so that the lubricating oil transferred from the oil scraping plate 142 and the oil box 141 can be transferred to the oil collector 151 more efficiently, and the oil collecting efficiency of the oil collector 151 can be greatly improved.
In one example of the present utility model, the oil scraper 142 includes: a connection portion 1421 and an extension portion 1422 connected thereto, and the connection portion 1421 is fixedly connected to the sprocket 120; for example, the connecting portion 1421 is integrally formed with the extending portion 1422.
That is, the connection portion 1421 is used to connect with the sprocket 120, for example, by welding between the connection portion 1421 and the sprocket 120; the extension 1422 is used to stir the lubricant, and stir and splash the lubricant in the wetting zone to the non-wetting zone.
In one example of the present utility model, as shown in fig. 2, the connection portion 1421 and the extension portion 1422 are both arc-shaped plate structures; thus, the working area of the oil scraping plate 142 can be increased, and the quantity of the transported lubricating oil can be increased; for example, the oil scraping plate 142 may be cut by a circular arc pipe, so that it is more convenient to obtain the oil scraping plate 142; alternatively, the wiper 142 may be welded by a plate material.
In one example of the utility model, the extension 1422 extends from the connection 1421 in a direction away from the drive shaft 110; this allows sufficient space for the installation of oil collector 151 to avoid interference of extension 1422 with oil collector 151.
A drive axle according to the second aspect of the present utility model includes a drive axle lubrication mechanism 100 as described above.
In the working process of the drive axle of the flat-bottomed vehicle, the drive shaft 110 drives the chain wheel 120 to rotate in the shell 130, and the oil box 141 and/or the oil scraping plate 142 positioned on the chain wheel 120 periodically rotate in the oil cavity 132 along with the chain wheel 120, so that lubricating oil positioned in the oil cavity 132 is driven to leave an infiltration area of the oil cavity 132 and enter the shaft cavity 131 along the oil inlet channel 133, thereby lubricating the bearing 160 positioned in the shaft cavity 131, avoiding damage such as pitting of the bearing 160, falling off of a retainer and the like caused by impact load of the bearing 160, and greatly prolonging the service life of the bearing 160; correspondingly, by using the lubricating mechanism 100, the service life of the flat bottom vehicle is greatly prolonged, and the failure rate is reduced.
While the exemplary embodiments of the present axle lubrication mechanism 100 and the axle having the same have been described in detail hereinabove with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the specific embodiments described above and that various combinations of the technical features and structures of the present utility model may be made without departing from the scope of the utility model, which is defined in the appended claims.
