Abstract
A segmented bearing ring suitable for low-speed rotation comprises a hollow column. The hollow column comprises a middle segment, a first oil hole segment and a second oil hole segment. The segmented bearing ring further comprises a plurality of rows of oil guide through holes and oil guide grooves formed in the first oil hole segment. The hollow column comprises a hollow axis. An included angle of 8 degrees to 15 degrees is formed between the arrangement direction of the multiple rows of oil guide through holes and the center axis. The area of the part, occupied by the oil guide through holes, of the outer surface of the hollow column is half of the total area of the hollow column. The oil guide grooves are formed in the outer surface of the hollow column, and each oil guide groove communicates with one oil guide through hole of one row of oil guide through holes corresponding to the oil guide groove. According to the segmented bearing ring, lubricating oil can be sequentially guided into the surface of a bearing, and meanwhile the guide-in speed of the lubricating oil is controlled to be matched with the rotating speed of the bearing; and meanwhile, by means of the oil guide grooves, the aims of enhancing the self-lubricating effect and saving a lubricating agent can be achieved.

Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:
Fig. 1 is the structural representation of a kind of segmentation race ring suitable in slow rotation provided by the invention.
Detailed description of the invention
Below based on accompanying drawing, specific embodiments of the invention are further elaborated.It should be appreciated that the protection domain herein explanation of the embodiment of the present invention being not intended to limit the present invention.
Referring to Fig. 1, it is the structural representation of a kind of segmentation race ring 100 suitable in slow rotation provided by the invention.The described segmentation race ring 100 suitable in slow rotation includes a hollow cylinder 10, multiple rows of Oil Guide through hole 11 being arranged on described hollow cylinder 10, and a plurality of oil guide groove 12 being arranged on part Oil Guide through hole 11 side.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, segmentation race ring provided by the present invention 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 hollow cylinder 10 is divided into three sections, including an interlude 102, is separately positioned on the first, second oilhole section 103,104 at the two ends of described interlude 102.The radial thickness of described interlude 102 is less than the radial thickness of described first, second oilhole section 103,104.
Described multiple rows of Oil Guide through hole 11 is opened on the sidewall of first, second oilhole section 103,104 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 and this segmentation race ring be used for relatively rugged environment, the orientation of described multiple rows of Oil Guide through hole 11 and the angle theta of described central axis 101 are 8 degree to 15 degree.In the present embodiment, the orientation of described Oil Guide through hole 11 is 10 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 8 degree to 15 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 oil guide groove 12 is arranged on the outer surface of the first oilhole section 103 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 lubricant extrusion 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.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 lubricant.Angle between bearing of trend and the orientation of Oil Guide through hole of described oil guide groove 12 is acute angle, is strengthening lubricant effect.
The described segmentation race ring more than 100 suitable in slow rotation is used in and is in the different machinery using environment, such as engineering machinery, building machinery, agriculture and forestry machinery, described first oilhole section 103 is stretched out the inside of machinery and is in a kind of environment, such as Sand Dust Environment, and the second oilhole section 104 is arranged on the inside of machinery, use environment better.Compared with prior art, multiple rows of orientation of Oil Guide through hole 11 of the described segmentation race ring 100 suitable in slow rotation and the angle of central axis are arranged between 8 degree to 15 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 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, simultaneously because the existence of described oil guide groove 12 can strengthen the effect of self-lubricating and the purpose saving lubricant.
These are only presently preferred embodiments of the present invention, be not used to limitation protection scope of the present invention, any amendment, equivalent replacement or improvement etc. in spirit of the present invention, be all encompassed in scope of the presently claimed invention.
