Abstract
The invention discloses a shaft sleeve which comprises a shaft sleeve body; an oil-injecting hole is formed on a side wall of the shaft sleeve body; cold-extruding reticulate-pattern wires are arranged on the inner surface of the shaft sleeve body; an oil groove is disposed on the inner surface of the shaft sleeve body and is communicated with the oil-injecting hole; the oil groove extends from an end surface of one end of the shaft sleeve body to a position near the other end of the shaft sleeve body. Dust particles entering the shaft sleeve from the outside and metal particles generated by abrasion can be squeezed into the oil groove during friction, and discharged along the oil groove, which avoids severe abrasion, and prolongs the service life of the shaft sleeve and a rotating shaft.
Description
Technical field
The present invention relates to a kind of heavy engineering machinery and use axle sleeve.
Background technique
Heavy engineering such as excavator, bulldozer machinery, mostly its target is earth, sandstone.Such machinery has the coupling shaft that many places are combined by rotating shaft and axle sleeve; Mostly the axle sleeve inner surface of traditional coupling shaft is smooth flat; Reduce pivoting friction through lubricant oil between axle sleeve and the rotating shaft,, also offer the oil storage of " ∞ " shape groove on the axle sleeve inner surface for the ease of oil storage.Because the working environment of engineering machinery is open, very easily sucks sand and dust in the coupling shaft, makes deterioration of lubricant, and the metal granule that suction particulate matter or wearing and tearing produce gets into the abrasive wear that forms behind the lubricant oil, can aggravate the wearing and tearing of rotating shaft; In addition, because of coupling shaft place oil storage poor effect, the user can only solve lubrication problem through the lubricant oil of repeatedly in the axle sleeve of coupling shaft, annotating, and oil consumption is big, and maintenance cost is high.
Chinese patent CN101162028A discloses a kind of cob-webbing quenching axle sleeve, and the sleeve body internal surface of this axle sleeve has quenching spoken parts in traditional operas reticulate pattern line, and spoken parts in traditional operas reticulate pattern line is crossed as netted; Interval between the reticulate pattern line can regulated at will; The reticulate pattern wire casing that forms between the reticulate pattern line can store up lubricant oil, does not need often in axle sleeve, to annotate lubricant oil, has solved the big problem of oil consumption; And friction factor also the friction factor than traditional axle sleeve is little, thereby but reduce the wearing and tearing of rotating shaft.But this axle sleeve still can't solve by the external world and get into aggravation rotating shaft and the axle sleeve wear problems that the particulate matter in the axle sleeve causes.
Summary of the invention
The purpose of this invention is to provide the axle sleeve that a kind of metal granule that can the particulate matter and the wearing and tearing of suction be produced is discharged.
The present invention adopts following technological scheme: a kind of axle sleeve; Comprise sleeve body; Offer oil hole on the sidewall of sleeve body; Said sleeve body internal surface is laid with cold hobbing reticulate pattern line, also offers the oil groove that is communicated with said oil hole on the internal surface of said sleeve body, and said oil groove extends inwardly to the other end position near sleeve body by the end face of an end of sleeve body.
Said oil groove is communicated with said oil hole through the annular groove that is opened on the sleeve body internal surface, and said oil hole is communicated with said annular groove, and said oil groove is communicated with said annular groove.
Said oil groove is helical or wire.
Adopt the axle sleeve of said structure; Owing to offer the oil groove that extends near the other end position to sleeve body by sleeve body one end on the internal surface of sleeve body; The metal granule that is entered into the sand and dust particle in the axle sleeve and the generation of wearing and tearing by the external world can be squeezed into oil groove at friction process; And along the oil groove discharge, avoid serious wearing and tearing take place, prolonged the working life of axle sleeve and rotating shaft.
In addition, the sleeve body internal surface is through superhard compounding, and dimensional stability is good, and surface hardness reaches as high as HRC70 greater than HRC58, and salt spray test can reach 140 hours, can satisfy wear-resistant and requirement anti-corrosion; High, the inner soft structure of axle sleeve surface hardness also makes axle sleeve under the situation of bearing greater impact load, be difficult for fragmentation simultaneously, and its fatigue resistance is improved.

Embodiment
The embodiment one of axle sleeve of the present invention: shown in Fig. 1-3; Comprise sleeve body 1; Sleeve body 1 material is alloyed steel (like 42CrMo, 40 CrMo, GCr15); The internal surface of sleeve body 1 forms reticulate pattern line 3 through cold hobbing, and the reticulate pattern wire casing that forms between the reticulate pattern line 3 can storing lubricating oil, and the gap size between the reticulate pattern line 3 can be adjusted according to customer requirements.The position evenly offers four oil holes 4 along sleeve body 1 circumferential arrangement between being positioned at wherein on the sidewall of sleeve body 1; Oil hole 4 is a through hole; Corresponding oil hole 4 positions offer 5, four oil holes 4 of an annular groove and all are communicated with annular groove 5 on the internal surface of sleeve body 1.On the internal surface of sleeve body 1, also offer helical oil groove 2, oil groove 2 extends inwardly to the other end position near sleeve body 1 by an end of sleeve body 1.
The embodiment two of axle sleeve of the present invention: shown in Fig. 4-6, the difference of present embodiment and the foregoing description is that said oil groove 6 is bearing of trend and the axial consistent linear structure of sleeve body, and is three that circumferentially lay at interval along sleeve body.
In the foregoing description, the internal surface of sleeve body 1 is through superhard compounding, and its manufacturing process is: cleaning-preheating-nitriding-oxidation, the depth of penetration after the processing can reach more than the 100 μ m.In concrete working procedure; In sleeve body 1, annotate lubricant oil through oil hole 4; Get in the oil groove through annular groove 5, the metal granule that is entered into the sand and dust particle in the sleeve body 1 and the generation of wearing and tearing by the external world can be squeezed into oil groove at friction process, and discharges along oil groove.
Claims (3)
1. axle sleeve; Comprise sleeve body; Offer oil hole on the sidewall of sleeve body; It is characterized in that: said sleeve body internal surface is laid with cold hobbing reticulate pattern line, also offers the oil groove that is communicated with said oil hole on the internal surface of said sleeve body, and said oil groove extends inwardly to the other end position near sleeve body by the end face of an end of sleeve body.
2. axle sleeve according to claim 1 is characterized in that: said oil groove is communicated with said oil hole through the annular groove that is opened on the sleeve body internal surface, and said oil hole is communicated with said annular groove, and said oil groove is communicated with said annular groove.
