As further improvement of the utility model, the oil sealing set group includes oil seal washer, closure pad and oil sealing and fixed
Piece.
As further improvement of the utility model, the oil storage ditch is two, is symmetrically set in the logical of the feed screw nut
On hole surface.
As further improvement of the utility model, the oil storage ditch runs through the through-hole surfaces.
As further improvement of the utility model, the oil storage ditch is arranged on the through-hole surfaces close to the portion of its one end
On point.
As further improvement of the utility model, the depth of the oil storage ditch is twice of the thread depth.
The beneficial effects of the utility model are：The anti-recharging oil device of the screw drive in the bottom of screw rod by setting oil-sealing sleeve
Group, and oil storage ditch is set in the through-hole surfaces of feed screw nut, the grease band in the oil sealing set group of screw rod bottom is back to feed screw nut
Place simultaneously stores, constantly to the screw rod and feed screw nut for doing stretching motion supplement the action of grease so that screw rod and silk
Thick stick nut has been always maintained at oil condition, avoids wearing and producing noise, substantially increases screw rod service life.

Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But guarantor of the present utility model
Shield scope is not limited to following embodiments, i.e., is made in every case with present utility model application the scope of the claims and description simple
Equivalent changes and modifications, all still belong within the utility model patent covering scope.
It is a kind of anti-recharging oil device of screw drive described in the utility model refering to Fig. 1, including feed screw nut 1, screw rod 4
With outer tube 5, feed screw nut 1 is fixed in one end of outer tube 5, and feed screw nut center is provided with the through hole 2 worn for screw rod, through hole 2
Surface is provided with the thread engaged with the screw thread of the outer surface of screw rod 4, and the inner of screw rod 4 is arranged in feed screw nut 1 by screw thread engagement
Through hole 2 in, and backstop screw 6 is fixed with the inner end face of screw rod 4.Set on the inner of screw rod 4 against backstop screw 6
There is the oil sealing set group 7 for repairing, the through-hole surfaces of feed screw nut are provided with the oil storage ditch 3 along its axis direction, the depth of oil storage ditch
Depth of the degree more than thread.
Wherein, oil sealing set group 7 includes oil seal washer 71, closure pad 72 and oil sealing stator 73.
Refering to Fig. 2-3, the oil storage ditch on feed screw nut 1 is two, through the through-hole surfaces, and is symmetrically set in leading screw spiral shell
