Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
The structural representation of a kind of reinforced bearing of self-lubricating straight trough being applicable to quick rotation that Fig. 1 provides for this utility model.
Fig. 2 be a kind of reinforced bearing of self-lubricating straight trough being applicable to quick rotation of Fig. 1 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 the explanation to this utility model embodiment is not used to limit protection domain of the present utility model herein.
Refer to Fig. 1 and Fig. 2, the structural representation of its a kind of reinforced bearing of self-lubricating straight trough 100 being applicable to quick rotation provided for this utility model.The described reinforced bearing of self-lubricating straight trough 100 being applicable to quick rotation 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, lubricating oil, also includes ball when of necessary, and 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 it be less than 1200 turns and be then considered at a slow speed, be then considered at a high speed more than 1200 turns per minute.Therefore, the reinforced bearing of self-lubricating straight trough provided by the utility model uses be applicable to the device of the quick rotation being 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 have numerical value not.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, this straight line i.e. the orientation of 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 the thickness that formed of the Extraction rate of lubricating oil that is accommodated in this Oil Guide through hole 11 and 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, in the present embodiment, and a diameter of 3 millimeters of described Oil Guide through hole 11.Further, since different-diameter and the hollow cylinder 10 of wall thickness, the size of its outer surface is the most different, and the density degree of the Oil Guide through hole 11 that it is offered is the most different, and its lubricant effect caused is the most 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.The lubricating oil of its storage in use can also be added lubricating oil that is necessary or that miss to this bearing simultaneously.One of them Oil Guide through hole 11 in described oil guide groove 12 row's Oil Guide through hole 11 corresponding thereto connects, simultaneously, angle β between bearing of trend and the orientation of described Oil Guide through hole 11 of described oil guide groove 12 is acute angle, and this acute angle is less than 30 degree and more than 10 degree.In the present embodiment, described oil guide groove 12 is connected with an Oil Guide through hole 11 on 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.Additionally, owing to the angle β between bearing of trend and the orientation of described Oil Guide through hole 11 of described oil guide groove 12 is acute angle, and this acute angle is less than 30 degree and more than 10 degree, when axle is when rotating, this oil guide groove 12 can receive the lubricating oil spilt from Oil Guide through hole 11 at once and add lubricant that is necessary or that miss, reaches to strengthen the purpose of lubrication.
Compared with prior art, multiple rows of orientation of Oil Guide through hole 11 and the angle of central axis of the described reinforced bearing of self-lubricating straight trough 100 being applicable to quick rotation are 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, the boot speed controlling this lubricating oil makes it match with the velocity of rotation of bearing, form the oil film of uniform and thin thickness.And the bearing for slow rotation is not the most 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 or improvement etc. in this utility model spirit, all contain in right of the present utility model.
