Abstract
The utility model relates to the technical field of electric shovel thrust shafts, in particular to an electric shovel thrust shaft with sustainably lubricant sliding bearings. The electric shovel thrust shaft comprises a thrust shaft and sliding bearings arranged at two ends of the thrust shaft. The electric shovel thrust shaft is characterized in that the inner surface of each sliding bearing is provided with isosceles trapezoid grooves uniformly, wherein each isosceles trapezoid groove is internally provided with a group of balls; two ends of each isosceles trapezoid groove are respectively provided with a retaining sheet; the outer surface of each sliding bearing is provided with an oil groove along the circumference and the inner side of each oil groove is provided with an oil charging hole; and the oil charging hole is communicated with the isosceles trapezoid groove. The number of the isosceles trapezoid grooves is 3-6. After the sliding bearings are used, the service life of the thrust shaft can be prolonged by twelve months, the maintenance cost is reduced and the overhaul rate is lowered.
Description
Technical field
The utility model relates to a power shovel pushing axle technical field, particularly a kind of power shovel pushing axle that is provided with sustainable lubricated sliding bearing.
Background technique
The pushing axle is the vitals of surface mining power shovel, in equipment operation, plays transmission and supporting effect, bear bigger load, thereby bearing wear is also comparatively serious.
The sliding bearing lubricating poor that is adopted at present, in transmission process, the oiling agent that the bearing support oil hole injects impouring sliding bearing fully is inner, the phenomenon of dry grinding between pushing axle and the bearing occurs, has a strong impact on the working life of pushing axle.Only the two weeks time, bearing part will produce abnormal voice, smolder, and seriously can cause the wearing and tearing of pushing axle to cause and scrap.
Summary of the invention
The purpose of the utility model provides a kind of power shovel pushing axle that prolongs the sustainable lubricated sliding bearing of being provided with of pushing axle working life.
The purpose of the utility model realizes through following technical proposals:
The power shovel pushing axle that is provided with sustainable lubricated sliding bearing of the utility model; Comprise the pushing axle, be located at the sliding bearing that this pushes the axle two ends; It is characterized in that evenly being provided with the isosceles trapezoid groove at the internal surface of said sliding bearing; In this isosceles trapezoidal groove, be provided with one group of ball, be provided with catch, along the circumferential direction be provided with oil groove at the outer surface of said sliding bearing at the two ends of said isosceles trapezoid groove; Be provided with oil hole in this oil groove inboard, this oil hole is communicated with described isosceles trapezoid groove.
The quantity of said groove is 3-6.
The characteristics of the power shovel pushing axle that is provided with sustainable lubricated sliding bearing of the utility model are:
The internal surface that is employed in sliding bearing is established the isosceles trapezoid groove and is established the mode of structure of oil groove at the outer surface of sliding bearing, and the lubricant oil of injection can be entered in the sliding bearing, guarantees to push bearing and obtains sufficient lubrication.After using the sliding bearing of the utility model, can prolong 12 months working life of pushing axle, reduce maintenance cost, reduce the maintenance rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional view of the sliding bearing of the utility model.
Fig. 3 is the side view of the sliding bearing of the utility model.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
Like Fig. 1, Fig. 2, shown in Figure 3; The power shovel pushing axle that is provided with sustainable lubricated sliding bearing of the utility model; Comprise pushing axle 4, be located at the sliding bearing 1 that this pushes axle 4 two ends; It is characterized in that evenly being provided with isosceles trapezoid groove 6 at the internal surface of said sliding bearing 1, the quantity of this groove 6 is 3-6.In this isosceles trapezoidal groove 6, be provided with one group of ball 7; Be provided with catch 8 at the two ends of said isosceles trapezoid groove 6; Outer surface at said sliding bearing along the circumferential direction is provided with oil groove 2, is provided with oil hole 3 in these oil groove 2 inboards, and this oil hole 3 is communicated with described isosceles trapezoid groove 6.
Lubricant oil gets in the sliding bearing 1 through oil hole 3, and pushing axle 4 is lubricated.The oil groove 2 of sliding bearing 1 outer surface can prevent that lubricant oil is excessive, along with the rolling of ball 7 can be refueled for pushing axle 4 continuously, and then realizes sustainable lubricated.
Label 5 among Fig. 1 is a driving gear.
After using the sliding bearing of the utility model, can prolong 12 months working life of pushing axle, reduce maintenance cost, reduce the maintenance rate.
Claims (2)
