Abstract
The utility model discloses a graphite axle sleeve, it includes the axle sleeve body, and leave along the circumference on axle sleeve body surface has a plurality of recesses, and every recess is formed with the channel along axle sleeve body axial medial surface, and axle sleeve body lateral surface corresponds the position with the channel and has seted up the oil filler point, and axle sleeve body medial surface is formed with spiral oil groove, and axle sleeve body internal surface forms the twill line through the cold extrusion. Oil gets into from the oil filler point, and in the channel of inflow axle sleeve body medial surface, the oil in the channel spreads to spiral oil groove for the position that whole axle sleeve body medial surface and coupling touched is all very lubricated, and graphite material's axle sleeve itself has self -lubricating, high temperature resistant, corrosion resistant characteristic.
Description
Technical field
This utility model relates to a kind of axle sleeve, particularly relates to a kind of graphite bushing.
Background technology
Axle sleeve is the tubular machine components being enclosed within rotating shaft, it it is an ingredient of sliding bearing, axle sleeve is integrally-built, it it is relative motion between axle and axle sleeve during rotation, axle sleeve is in During Process of Long-term Operation, journal surface is subject to the extruding force of expansion set and the effect of composite machine power, will cause its permanent deformation, diameter or reduction.
Accordingly, it is desirable to provide a kind of new technical scheme solves the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is to provide the graphite bushing of a kind of life-span length.
For solving above-mentioned technical problem, graphite bushing of the present utility model, it includes sleeve body, described sleeve body surface circumferentially has multiple groove, each groove is formed with conduit along sleeve body axially inner side face, described sleeve body lateral surface and conduit correspondence position offer oil filler point, and described sleeve body medial surface is formed with helical oil groove, and described sleeve body inner surface forms twill line through cold extrusion.
Described sleeve body surface circumferentially has 4 grooves, and 4 grooves are cross is distributed in sleeve body surface.
The beneficial effects of the utility model: oil enters from oil filler point, flow in the conduit of sleeve body medial surface, oil in conduit diffuses to helical oil groove, the position that whole sleeve body medial surface contacts with axle is all lubricated very much, the axle sleeve of graphite material, itself has self-lubricating, characteristic high temperature resistant, corrosion resistant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, sleeve body, 2, groove, 3, conduit, 4, oil filler point, 5, helical oil groove, 6, twill line.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to protection domain of the present utility model.
As shown in Figure 1, graphite bushing of the present utility model, it includes sleeve body 1, sleeve body 1 surface circumferentially has multiple groove 2, each groove 2 is formed with conduit 3 along sleeve body 1 axially inner side face, and sleeve body 1 lateral surface and conduit 3 correspondence position offer oil filler point 4, and sleeve body 1 medial surface is formed with helical oil groove 5, can increasing the lubricant effect of rotating shaft and axle sleeve, sleeve body 1 inner surface forms twill line 6 through cold extrusion.Oil groove is arranged to helical form, when rotating shaft rotates in axle sleeve, it is possible to make the lubricating oil viscosity in oil groove form lubricating oil film in rotating shaft, and lubricating oil film is possible to prevent the air outside axle sleeve hole, dust to enter in axle sleeve hole, thus antirust ability is strong.
Sleeve body 1 surface circumferentially has that 2,4 grooves 2 of 4 grooves are cross is distributed in sleeve body 1 surface.
Oil enters from oil filler point 4, flowing in the conduit 3 of sleeve body 1 medial surface, the oil in conduit 3 diffuses to helical oil groove 5 so that the position that whole sleeve body 1 medial surface contacts with axle all lubricates very much, the axle sleeve of graphite material, itself has self-lubricating, characteristic high temperature resistant, corrosion resistant.
Claims (2)
