The purpose of this utility model is for a kind of high-speed machine tool copper alloy shaft sleeve being provided, greatly improving greasy property, reduces the wear-resisting of product, increases the service life.
For achieving the above object, the technical solution of the utility model is:
High-speed machine tool copper alloy shaft sleeve, it is characterized in that: comprise body, form embedded toroidal graphite bar at the inwall of described body, between described annular graphite bar, form circular groove, the two bottom sides of described circular groove forms inclination oil pocket, be provided with graphite silk in inclination oil pocket; The degree of depth that described annular graphite bar embeds, at 5-10mm, forms oil pocket between the upper and lower two ends of described graphite bar inside bottom and described body, forms the aperture communicating with described oil pocket on described graphite bar;
On the outer wall of described body, form multiple grooves, in described groove, fill graphite layer, between described bottom portion of groove and described body outer wall, form large oil pocket, the cross-sectional diameter of described large oil pocket is greater than the cross-sectional diameter of described groove, forms boss support graphite layer in the bottom of described large oil pocket.
Further, the port, two ends of described body forms annular groove, is embedded with graphite bar at described annular groove, and the degree of depth that described graphite bar embeds is at 5-10mm.
Further, the described groove arrangement that assumes diamond in shape.
Further, described groove indention is arranged.
Further, the spacing between described groove is at 5-10cm.
Further, the spacing between described graphite bar is at 10-20cm.
Further, described inclination oil pocket communicates with described oil pocket and forms oil seam.
Further, multiple sulculuses arranged in a crossed manner are formed on the bottom of described large oil pocket.
The utility model compared with prior art, has following beneficial effect:
1, in order to change the lubrication effect of whole axle sleeve, the utility model comprises body, forms embedded toroidal graphite bar at the inwall of described body, between described annular graphite bar, forms circular groove, the two bottom sides of described circular groove forms inclination oil pocket, be provided with graphite silk in inclination oil pocket; The degree of depth that described annular graphite bar embeds, at 5-10mm, forms oil pocket between the upper and lower two ends of described graphite bar inside bottom and described body, forms the aperture communicating with described oil pocket on described graphite bar; Such setting, the utility model, in the setting by graphite bar, can increase lubricating between body inwall and axostylus axostyle, adds lubricant oil without adding or reducing, and improves usability, increases the service life.In addition, in order to protect graphite bar, delay its wearing and tearing, the setting of described circular groove, can carry out trapped fuel, reduces the wearing and tearing of graphite bar, and both are used in conjunction with, and reduce the amount of oiling, have also reduced the loss of graphite.
The two bottom sides of described circular groove forms inclination oil pocket, between the upper and lower two ends of described graphite bar inside bottom and described body, form oil pocket, according to the requirement that is provided with of reality, described inclination oil pocket communicates with described oil pocket and forms oil seam, form like this flowing of lubricant oil, be evenly distributed, improve the lubricated using effect of entirety.
2, on the outer wall of body described in the utility model, form multiple grooves, in described groove, fill graphite layer, between described bottom portion of groove and described body outer wall, form large oil pocket, the cross-sectional diameter of described large oil pocket is greater than the cross-sectional diameter of described groove, forms boss support graphite layer in the bottom of described large oil pocket.The utility model is in the time that as installed is used, between outer wall and large press, need to reduce friction, so setting of graphite annulus, can increase lubricity, reduce wear, it is carried out to numerical value research simultaneously, through investigation and comparison repeatedly repeatedly, spacing between described groove is best at 5-10cm, lubricated being evenly distributed rationally that graphite layer produces.Generally, groove indention described in the utility model is arranged, or assumes diamond in shape and be arranged as the best.
3, the utility model forms annular groove between described evagination fixed end and described body outer wall, is embedded with annular graphite circle at described annular oil groove; This position, due to the outside workpiece of contact, cause easily wearing and tearing too much, so the utility model delays wearing and tearing by embedding annular graphite circle, improve its lubrication effect, so the utility model improves this, annular graphite circle snaps onto in annular groove, reduce the wearing and tearing at this position, increase the service life.
As from the foregoing, the utility model improves greasy property greatly, reduces the wear-resisting of product, increases the service life.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
