Description
Technical field
The utility model relates to deep-well pump field, and more particularly, it relates to a kind of for the axle sleeve on deep-well pump splined shaft.
Background technique
Manufacture field at deep-well pump, because the friction between deep-well pump pump shaft axle sleeve and guide vane bearing can be directed at the wearing and tearing of pump shaft and guide vane bearing, the gap between axle sleeve and guide vane bearing is increased, cause the concentricity of impeller and pump shaft poor, the Yang Cheng and the efficiency that affect water pump, even make damage parts.For little electric pump, consider the many factors such as cost of production, mounting point and processing, pump shaft generally all adopts the cold drawn section bar of hexagonal section, between pump shaft and guide vane bearing, the general axle sleeves that adopt carry out wear prevention more, but existing axle sleeve structure is too simple, function singleness, easily strain, working life is short.
Model utility content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of have lubricating function for the axle sleeve on deep-well pump splined shaft.
For achieving the above object, the utility model provides following technological scheme: a kind of for the axle sleeve on deep-well pump splined shaft, comprise axle sleeve body, described axle sleeve body is made up of with the annular flange being connected with body one end one a body, described inboard wall of tube body is at least distributed with two lug bosses that are axial directional distribution, described lug boss forms by being multiple projections of circle distribution on inboard wall of tube body, between adjacent two projections of same axial direction, be provided with lubricated portion, described lubricated portion comprises two side plates that connect between two projections that same axial direction is adjacent, the projection of described two side plates and respective ends surrounds a cavity, in described cavity, be provided with on cavity, the dividing plate of lower separation, dividing plate top is the lubricating cavity with packing, the bottom of dividing plate is the shoe cream room that stores lubricant oil, described dividing plate is provided with weepage holes, described flange is provided with anti-skid structure.
The utility model is further set to: described bumping surface is the arc surface caving inward to the one side of axis centre, and the radian of described arc surface is less than the circular arc radian of the maximum inscribed circle of lug boss.
The utility model is further set to: the anti-skid structure on described flange is to be axial distribution to form towards the strip groove of body one side at flange.
The utility model is further set to: described weepage holes is provided with multiple and is evenly distributed on dividing plate.
The utility model is further set to: described packing is asbestos or sponge.
Compared with prior art, the beneficial effects of the utility model are: the lubricant oil in the shoe cream room of this axle sleeve enters lubricating cavity by the weepage holes on dividing plate, through packing, pump shaft is lubricated again, effectively ensure the lubricating maintenance between axle sleeve and pump shaft, the lubricant oil simultaneously flowing out can also be lubricated guide vane bearing, has increased the working life of the deep-well pump that uses this axle sleeve.

Embodiment
Referring to figs. 1 through Fig. 5, the utility model is described further for the axle sleeve embodiment on deep-well pump splined shaft.
A kind of for the axle sleeve on deep-well pump splined shaft, comprise axle sleeve body 1, described axle sleeve body 1 is made up of with the annular flange 12 being connected with body 11 one end one a body 11, described body 11 inwalls are at least distributed with two lug bosses 2 that are axial directional distribution, described lug boss 2 forms by being multiple projections 21 of circle distribution on body 11 inwalls, be generally 3 or 6, corresponding with the groove of splined shaft 4, between adjacent two projections 21 of same axial direction, be provided with lubricated portion 3, described lubricated portion 3 comprises two side plates 31 that connect between two projections 21 that same axial direction is adjacent, the projection 21 of described two side plates 31 and respective ends surrounds a cavity 32, in described cavity 32, be provided with on cavity 32, the dividing plate 33 of lower separation, dividing plate 33 tops are the lubricating cavity 321 with packing, wherein packing is asbestos or sponge, the bottom of dividing plate 33 is the shoe cream room 322 that stores lubricant oil, described dividing plate 33 is provided with weepage holes 331, described flange 12 is provided with anti-skid structure.Wherein lubricant oil is solid-state at normal temperatures, heating in the time that deep-well pump is worked, lubricant oil is melted into liquid, enter lubricating cavity 321 by the weepage holes 331 on dividing plate 33, through packing, pump shaft is lubricated again, effectively ensured the lubricating maintenance between axle sleeve and pump shaft, the lubricant oil simultaneously flowing out can also be lubricated guide vane bearing, has increased the working life of the deep-well pump that uses this axle sleeve.The fine slip preventing between guide vane bearing and axle sleeve of anti-skid structure energy on flange 12 simultaneously, simultaneously also can be for providing better lubricated between guide vane bearing or/and stator.
The one side that projection 21 is faced axis centre is the arc surface 211 caving inward, the radian of described arc surface 211 is less than the circular arc radian of the maximum inscribed circle of lug boss 2, in the time that this axle sleeve is assembled on the corresponding splined shaft 4 of specification, corresponding radian on arc surface 211 camber ratio splined shafts 4 on projection 21 is little, make to leave gap between projection 21 and splined shaft 4, the lubricant oil flowing out so just can, toward other lubricated portion 3 diffluences, also can flow out outside axle sleeve, has improved lubricated scope and effect.
Anti-skid structure on flange 12 is to be axial distribution to form towards the strip groove 121 of body 11 one sides at flange 12.Strip groove 121 can prevent that the guide vane bearing that is fixed on this place from circumferentially rotating.
Weepage holes 331 is provided with multiple and is evenly distributed on dividing plate 33, makes the oil leaking out can be dispersed.
