The utility model relates to a novel wear-resisting bearing bush, which is in a semi-cylindrical shape and comprises an outer bearing bush and an inner bearing bush. The outer side wall of the inner bearing bush is provided with a plurality of oil storage grooves perpendicular to the central axis of the inner bearing bush, and each oil storage groove is provided with an oil leakage hole communicated with the inner side of the inner bearing bush. Through setting up the tank filler to pour into lubricating oil in the oil storage tank, the tank filler with all the oil storage tank all communicates with each other, the one end of tank filler extends to the one end of axle bush and forms the oil filler hole.

Further, still including being located the inboard inner liner of interior axle bush, be equipped with a plurality of parallels on the inside wall of inner liner the oil groove of interior axle bush axis, the quantity of oil groove with the quantity of oil storage tank equals. The oil leakage holes are sequentially distributed at a plurality of positions of the oil leakage groove, second oil leakage holes are arranged at positions on the oil leakage groove corresponding to the oil leakage holes, namely, each oil leakage groove is communicated with the oil leakage groove through one oil leakage hole and the second oil leakage hole corresponding to the oil leakage hole.

Furthermore, the oil filling groove is positioned on the outer side wall of the inner bearing bush and penetrates through all the oil storage grooves.

Further, the oil filling groove is located on the inner side wall of the outer bearing bush.

Furthermore, the oil filling groove is arranged in parallel to the central axis of the inner bearing bush.

The utility model has the advantages that: the consumption time of lubricating oil is prolonged, so that the bearing bush is more wear-resistant, and the service life of the bearing bush is prolonged; the arrangement of the oil groove further prolongs the consumption time of lubricating oil, increases the wear resistance of the bearing bush and prolongs the service life of the bearing bush; the arrangement of the inner liner layer reduces the equipment cost and makes the maintenance operation more convenient.

Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure, as the terms used are used to describe particular embodiments only, and are not intended to limit the exemplary embodiments based on the disclosure.

The first embodiment:

fig. 1 shows that the utility model relates to a novel wear-resisting axle bush, for the semicircle tube-shape, including axle bush 1 and interior axle bush 2. As shown in fig. 2, the outer side wall of the inner bearing shell 2 is provided with a plurality of oil storage grooves 21 perpendicular to the central axis of the inner bearing shell 2, and each oil storage groove 21 is provided with an oil leakage hole 22 communicating with the inner side of the inner bearing shell 2. Lubricating oil is injected into the oil storage tank 21 through the oil filling tank 4, the oil filling tank 4 is communicated with all the oil storage tanks 21, and one end of the oil filling tank 4 extends to one end of the bearing bush to form an oil filling port 41. The oil filling groove 4 is preferably arranged parallel to the center axis of the inner bearing shell 2. The oil filling groove 4 is positioned on the outer side wall of the inner bearing bush 2 and penetrates all the oil storage grooves 21.

Inject lubricating oil into oil filler groove 4 through oil filler hole 41, because oil filler groove 4 all communicates with each other with every oil storage tank 21, lubricating oil and then get into each oil storage tank 21 in, lubricating oil in the oil storage tank 21 passes through oil leak hole 22 and gets into between axle bush (promptly the utility model discloses) and the pivot for keep sufficient lubrication between axle bush and the bearing. After the lubricating oil between the bearing bush and the bearing is consumed, the lubricating oil stored in the oil storage tank 21 continuously enters between the bearing bush and the rotating shaft through the oil leakage hole 22, so that the consumption time of the lubricating oil is prolonged, the bearing bush is more wear-resistant, and the service life of the bearing bush is prolonged.

Second embodiment:

the second embodiment of the present invention is different from the first embodiment only in that: as shown in fig. 3, the oil filling groove 4 is located on the inner side wall of the outer bearing shell 1.

The third embodiment:

on the basis of above first embodiment or second embodiment, as shown in fig. 4, the utility model discloses a third embodiment is still including being located the inboard inner liner 3 of interior axle bush 2, be equipped with a plurality of parallels on the inside wall of inner liner 3 the oil groove 31 of interior axle bush 2 axis, oil groove 31's quantity with the quantity of oil storage tank 21 equals, oil leakage hole 22 distributes in proper order and sets up a plurality of oil groove 31's position, oil groove 31 go up with the corresponding position of oil leakage hole 22 all is equipped with second oil leakage hole 32, every promptly oil storage tank 21 all is linked together through an oil leakage hole 22 and the second oil leakage hole 32 corresponding with it with one oil leakage groove 31.

Lubricating oil in the oil storage tank 21 enters the oil lubrication groove 31 through the oil leakage hole 22 and the second oil leakage hole 32, and the lubricating oil moves under the action of sliding between the rotating shaft and the bearing bush, so that the lubricating oil in the oil lubrication groove 31 enters the space between the bearing bush and the rotating shaft, the lubricating oil is kept between the bearing bush and the bearing, the consumption time of the lubricating oil is further prolonged by the arrangement of the oil lubrication groove 31, the wear resistance of the bearing bush is increased, and the service life of the bearing bush is prolonged. After the axle bush carries out long-time work, the inner liner 3 can be prior to outer axle bush 1 and interior axle bush 2 and produce wearing and tearing, this moment, only need change the inner liner 3 can, reduced equipment cost, and convenient operation.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
