There is annular groove, the axle sleeve immediately below annular groove is provided with manhole, and arc is provided with axially outside below axle sleeve
Connected in star.The unnecessary lubricating oil so in annular groove, it is back to by through hole along arc groove in casing.But this side
Formula, which still has a small amount of oil, to be overflowed along rotating shaft outside set, and this mode is not suitable for axle sleeve both ends and is required for grease proofing structure.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of shaft sleeve device with fuel feeding and oil-returning structure, it
Can be lighter, convenient and effectively prevent oil leak, permeability phenomenon.
In order to solve the above technical problems, the utility model has the technology solution party of the shaft sleeve device of fuel feeding and oil-returning structure
Case is：
Including axle sleeve, axle sleeve is formed with the axis hole penetrated vertically；The both ends of axle sleeve offer oil seal groove respectively；Axis hole
Inwall is formed with oil storage tank；The side wall of axle sleeve offers the oil-feed port and oil-out radially extended, oil-feed port and oil-out point
It is not connected with oil storage tank；The side wall of axle sleeve offers the oil return pod apertures axially extended, and the oil return radially extended
Hole；Oil return pod apertures are connected with two oil seal grooves and spill port.
Oil sealing is equipped with the oil seal groove.
The axle sleeve is formed with alignment cavities.
The alignment cavities and oil return pod apertures are circumferentially arranged symmetrically.
The internal diameter of the oil seal groove is more than the internal diameter of axis hole.
The material of the axle sleeve is steel, copper or cast iron.
The inwall of the axle sleeve studs with copper sheathing.
What the utility model can reach has the technical effect that：
The utility model is simple and compact for structure, convenient for installation and maintenance and oil-leakage-prevention, permeability effect are good.

Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
The accompanying drawing of type embodiment, the technical scheme of the utility model embodiment is clearly and completely described.Obviously, it is described
Embodiment is part of the embodiment of the present utility model, rather than whole embodiments.Based on described of the present utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained on the premise of without creative work, all belongs to
In the scope of the utility model protection.Unless otherwise defined, technical term or scientific terminology used herein should be this reality
With the ordinary meaning that there is the personage of general technical ability to be understood in new art." comprising " used herein etc. is similar
The element that word means to occur before the word either cover the element for appearing in the word presented hereinafter or object and its wait by object
Together, other elements or object are not excluded for.
As shown in Figure 1 to Figure 3, the utility model has the shaft sleeve device of fuel feeding and oil-returning structure, including a cylinder
Axle sleeve 10, axle sleeve 10 is formed with the axis hole 17 penetrated vertically；The both ends of axle sleeve 10 offer oil seal groove 14, oil seal groove respectively
14 internal diameter is more than the internal diameter of axis hole 17；Oil seal groove 14 is used to assemble oil sealing 20, to prevent lubricating oil from being overflowed from both ends；
The inwall of axis hole 17 is formed with oil storage tank 18；Preferably, oil storage tank 18 is located at the middle part of axle sleeve 10；
The side wall of axle sleeve 10 offers the oil return pod apertures 16 axially extended, and the spill port 13 radially extended；
Oil return pod apertures 16 are connected with two oil seal grooves 14 and spill port 13；The long-pending oil of the bottom of oil seal groove 14 can pass through oil return water conservancy diversion
