Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
A kind of structural representation being applicable to the self-lubricating bearing circle of one-directional rotation at a slow speed that Fig. 1 provides for this utility model.
Fig. 2 is a kind of cross-sectional view being applicable to the self-lubricating bearing circle of one-directional rotation at a slow speed of Fig. 1.
Detailed description of the invention
Below based on accompanying drawing, specific embodiment of the utility model is further elaborated.It should be appreciated that be not used to limit protection domain of the present utility model to the explanation of this utility model embodiment herein.
Refer to Fig. 1 and Fig. 2, its a kind of structural representation being applicable to the self-lubricating bearing circle 100 of one-directional rotation at a slow speed provided for this utility model.The described self-lubricating bearing circle 100 being applicable to one-directional rotation at a slow speed includes a hollow cylinder 10 and multiple rows of Oil Guide through hole 11 being arranged on described hollow cylinder 10 and the mentioned ridge-shaped oil guide groove 12 on multiple inner surface being disposed on described hollow cylinder 10.It will be appreciated by those skilled in the art that, a complete bearing also includes some other component, such as bearing outer ring or inner ring, and lubricant, also include ball time necessary, these should be known by those skilled in the art.
Need it is further noted that quickly with defining at a slow speed in rotating speed, there is different defining in different fields.But in engineering machinery and automotive field, per minute then think at a slow speed less than 1200 turns, then think more than 1200 turns per minute at a high speed.Therefore, self-lubricating bearing circle provided by the utility model uses suitable in the device less than 1200 turns per minute.
Described hollow cylinder 10 can be made up of materials such as steel, ceramic material, bronze.In the present embodiment, described hollow cylinder 10 is made up of bronze.The diameter of this hollow cylinder 10 and the thickness of wall should design according to the field applied, and in the present embodiment, are also not limited thereof, and therefore the parameter designing of Oil Guide through hole 11 should use percentage ratio to limit, rather than the numerical value that tool is stopped.It is envisioned that due to the structure qualification of bearing, described hollow cylinder 10 must be a cylinder, and it has a central axis 101, as shown in the chain-dotted line of Fig. 1.Usual described axle or this hollow cylinder 10 are all around described central axis 101 and rotate.
Described multiple rows of Oil Guide through hole 11 is opened on the sidewall of described hollow cylinder 10 by drill bit.The center of the Oil Guide through hole 11 of each row point-blank, the orientation of this straight line i.e. the plurality of Oil Guide through hole 11, as indicated by the dashed line in figure 1.When axle rotates in described hollow cylinder 10, the orientation of described Oil Guide through hole 11 and the angle of central axis 101 can determine described in be accommodated in this Oil Guide through hole 11 the Extraction rate of lubricating oil and the thickness that formed of oil film.Therefore, when slow rotation, the orientation of described multiple rows of Oil Guide through hole 11 and the angle theta of described central axis 101 are 15 degree to 20 degree.In the present embodiment, the orientation of described Oil Guide through hole 11 is 15 degree with the angle of described central axis 101.The diameter of described Oil Guide through hole 11 can be to store lubricating oil between 2 millimeters to 5 millimeters, and in the present embodiment, the diameter of described Oil Guide through hole 11 is 3 millimeters.Further, since the hollow cylinder 10 of different-diameter and wall thickness, the size of its outer surface is also different, and the density degree of the Oil Guide through hole 11 that it is offered is also different, and its lubricant effect caused is also different.Therefore, machinery for slow rotation, and the multiple rows of orientation of Oil Guide through hole 11 is when being 15 degree to 20 degree with the angle of described central axis 101, the area of the outer surface of the described hollow cylinder 10 shared by described Oil Guide through hole 11 should be the half of the gross area of described hollow cylinder 10.
Described mentioned ridge-shaped oil guide groove 12 is opened in the inner surface of described hollow cylinder 10, and interval is arranged.The summit of described mentioned ridge-shaped oil guide groove 12 is positioned on the midpoint of the bus of described hollow cylinder 10, and is symmetrical arranged, and therefore the length of the groove of both sides, described summit is equal.The opening direction of described mentioned ridge-shaped oil guide groove 12 is perpendicular to described central axis 101, namely is perpendicular to the bus of described hollow cylinder 10.Due to described mentioned ridge-shaped oil guide groove 12 opening direction towards making so, the rotation direction of the described bearing being located in this self-lubricating bearing circle 100 should be identical with the opening direction of this mentioned ridge-shaped oil guide groove 12, the rotation direction of this bearing relatively, the relative motion of described self-lubricating bearing circle 100 should be contrary with the opening direction of this mentioned ridge-shaped oil guide groove 12.Because the opening direction of described mentioned ridge-shaped oil guide groove 12 is consistent, therefore described self-lubricating bearing circle 100 is adapted in the occasion of one-directional rotation to use, such as water pump, air exhauster etc..This be arranged on hollow cylinder 10 inner surface mentioned ridge-shaped oil guide groove 12 in use receive surplus lubricating oil, avoid by initialization phase or just add the lubricating oil stage, lubricant extrusion is caused to waste, lubricant that is that this bearing in use can also be added necessity by the lubricating oil of its storage simultaneously or that miss.
Compared with prior art, the described multiple rows of orientation of Oil Guide through hole 11 being applicable to the self-lubricating bearing circle 100 of one-directional rotation at a slow speed and the angle of central axis are arranged between 15 degree to 20 degree, and the area of the outer surface of the described hollow cylinder 10 shared by described Oil Guide through hole 11 should be the half of the gross area of described hollow cylinder 10, such that it is able to while allowing the lubricant in this Oil Guide through hole 11 lubricant in the Oil Guide through hole 11 in each row importing to the surface of this bearing successively when this bearing rotates, control the velocity of rotation that the boot speed of this lubricant makes it with bearing to match, simultaneously because the existence of described mentioned ridge-shaped oil guide groove 12 can strengthen the effect of self-lubricating and the purpose saving lubricant.
These are only preferred embodiment of the present utility model, be not used to limit to protection domain of the present utility model, any amendment, equivalent replacement or improvement etc. in this utility model spirit, be all encompassed in right of the present utility model.
