Description
Technical field
The utility model relates to a kind of excavation arbor coupling assembling, belongs to link technique field.
Background technology
Tradition excavation arbor connected mode is generally axle and cooperation position is lubricated in relative rotation, not lubricated with relatively-stationary position, owing to working long hours or affected by rain erosion etc., axle and the relative fixed position glutinous situation together of getting rusty often has generation, tradition axle and turntable without relatively rotate cause sticking together may be larger, and then affect the dismounting efficiency of axle, especially for being operated in mine, the excavator of the remote districts such as large outdoors colliery, its client's complaint is more obvious, therefore structure and the lubricating system of assembly of being necessary to be connected by shaft done corresponding improvement.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of excavation arbor coupling assembling, improves the lubricant effect of connecting portion, facilitates the dismounting of coupling assembling.
To achieve these goals, the technical solution adopted in the utility model is: a kind of excavation arbor coupling assembling, comprise flange, dust ring, axle and turntable, and axle has axis through-hole, also comprises axle sleeve; Flange is that ladder is cylindrical, and small end face one side is provided with cylinder shape groove, and large end face is provided with equally distributed a plurality of fixing hole; The intermediate circumference of axle has circumferential groove, and on circumferential groove, vertical axis direction has an axle oil filler point running through with axis through-hole; Dust ring is arranged on turntable two hole medial surfaces, axle sleeve is arranged in turntable two holes, cylinder rod is housed in the middle of two dust rings, axle is through axle sleeve, cylinder rod and dust ring, two chamfers of axle are exposed at respectively turntable outside, the chamfering of axle stretches in the cylinder shape groove of flange small end face one side, and the circular protrusions of flange small end face is against on axle sleeve, by fixing hole, flange is fixedly connected with turntable.
Further, axle two chamfering place vertical axis directions respectively have an axle oil outlet running through with axis through-hole.
Further, axle oil filler point, axis through-hole and axle oil outlet diameter are 8mm.
The beneficial effects of the utility model are: on cylinder rod, place oiling can realize the lubricated of whole axle coupling assembling, lubrication oil injects from the oil filler point of cylinder rod, can flow on axle, lubrication oil flows on axle can play effect lubricated between axle and cylinder rod, parts of lubricating oil can flow into axle oil filler point from circumferential groove, because axle oil filler point and axis through-hole connect, so lubrication oil can flow to by axis through-hole the two sides of axle, finally play the lubrication between axle and flange, between turntable aperture and axle, axle sleeve is installed, reduce axle and turntable without relatively rotating the possibility sticking together causing.
