Compared with prior art, the described multiple rows of orientation of Oil Guide through hole held suitable in the self-lubricating straight trough profile shaft of quick rotation and the angle of central axis are arranged between 30 degree to 45 degree, and more than 60 the percent of the gross area that area is described hollow cylinder of the outer surface of the described hollow cylinder shared by Oil Guide through hole, such that it is able to while allowing the lubricating oil in this Oil Guide through hole the lubricating oil in the Oil Guide through hole in each row importing to the surface of this bearing successively when this bearing quick rotation, control the velocity of rotation that the boot speed of this lubricating oil makes it with bearing to match, simultaneously because the existence of described oil guide groove can strengthen the effect of self-lubricating and the purpose saving lubricating oil.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
A kind of structural representation held suitable in the self-lubricating straight trough profile shaft of quick rotation that Fig. 1 provides for this utility model.
Fig. 2 be a kind of self-lubricating straight trough profile shaft suitable in quick rotation of Fig. 1 hold look up structural representation.
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.
Referring to Fig. 1 and Fig. 2, it holds the structural representation of 100 for a kind of self-lubricating straight trough profile shaft suitable in quick rotation that this utility model provides.The described self-lubricating straight trough profile shaft suitable in quick rotation holds 100 and includes a hollow cylinder 10, multiple rows of Oil Guide through hole 11 being arranged on described hollow cylinder, and is arranged on the oil guide groove 12 that each row's Oil Guide through hole 11 is other.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 lubricating oil, 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 straight trough profile shaft provided by the utility model holds and uses suitable in the device of the quick rotation more 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 quick rotation, the orientation of described multiple rows of Oil Guide through hole 11 and the angle theta of described central axis 101 are 30 degree to 45 degree.In the present embodiment, the orientation of described Oil Guide through hole 11 is 35 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 quick rotation, and the multiple rows of orientation of Oil Guide through hole 11 is when being 30 degree to 45 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 more than 60 the percent of the gross area of described hollow cylinder 10.
Described oil guide groove 12 is arranged on the outer surface of described hollow cylinder 10, and has V-arrangement cross section.Described oil guide groove 12 is in use receiving the lubricating oil of surplus, it is to avoid by initialization phase or just add the lubricating oil stage, causes pounding out of lubricant to waste.Lubricating oil that is that this bearing in use can also be added necessity by the lubricating oil of its storage simultaneously or that miss.One of them Oil Guide through hole 11 in described oil guide groove 12 row's Oil Guide through hole 11 corresponding thereto connects.In the present embodiment, described oil guide groove 12 is connected with an Oil Guide through hole 11 on most limit, such that it is able to be connected by the surfaces externally and internally making hollow cylinder 10, reaches to save the purpose of lubricating oil.
Compared with prior art, the described self-lubricating straight trough profile shaft suitable in quick rotation hold 100 multiple rows of orientation of Oil Guide through hole 11 and the angle of central axis be arranged between 30 degree to 45 degree, and the area of the outer surface of the described hollow cylinder 10 shared by described Oil Guide through hole 11 should be described hollow cylinder 10 the gross area more than 60 percent, such that it is able to while allowing the lubricating oil in this Oil Guide through hole 11 lubricating oil 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 lubricating oil makes it with bearing to match, form the oil film of uniform and thin thickness.And the bearing for slow rotation is not as applicable, because the slow rotation of bearing, it is impossible to making the lubricating oil film forming of importing, but pull into thread hachure, reverse side adds surface roughness.
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.
