Abstract
The utility model provides a shaft sleeve, which is reasonable in structure, fine in lubrication effect and long in service life and comprises a cylindrical shaft sleeve body. A plurality of oil pits used for storing oil are arranged on the inner wall of the shaft sleeve body and uniformly distributed on the shaft sleeve body, an X-shaped oil groove is further disposed on the inner wall of the shaft sleeve body along the axial direction of the shaft sleeve body, an oil feeding groove is further arranged on the shaft sleeve body along the axial direction of the shaft sleeve body and penetrates through the shaft sleeve body, and chamfers are disposed at edges of two opening ends of the shaft sleeve body. Lubricating oil can be uniformly distributed on a contact surface of the shaft sleeve body with a shaft by the aid of the oil pits disposed on the inner wall of the shaft sleeve body, redundant lubricating oil can be stored in the oil pits, and the oil pits have functions of supplementing the lubricating oil at any time. Oil storage quantity between the shaft sleeve body and the shaft when the shaft sleeve body is sleeved on the shaft can be increased by the aid of the X-shaped oil groove, and lubrication effect and lubrication strength of the shaft sleeve are enhanced. The oil feeding groove and the chamfers bring convenience for injecting the lubricating oil from the outside of the shaft sleeve body into the shaft sleeve body, and accordingly the shaft sleeve is convenient and speedy.
Description
Technical field
The utility model relates to a kind of axle sleeve.
Background technique
In the parts at the volley, axle is installed in axis hole, because long-term use can cause the wearing and tearing between axle and axis hole, so in order to improve the working life of axle, at the sheathed axle sleeve of axle outer surface, the axle sleeve here uses as a kind of sliding bearing, and axle sleeve self adopts hardness low, and the material that wear resistance is good forms.Although the axle sleeve structure under the prior art is each has something to recommend him, all also exists different problems, or use inconvenient, or self-lubrication function imperfection or the like, thus, if in use safeguard not prompt enough, then can cause axle and axle sleeve heavy wear, even the problem of scrapping exists.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, high lubricating effect, the axle sleeve of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of axle sleeve, comprise sleeve body cylindraceous, it is characterized in that: described sleeve body inwall is provided with a plurality of oil holes that are used for oil storage, and this oil hole is distributed on the sleeve body equably, also is provided with oil groove on the sleeve body inwall.
Of the present utility modelly further be set to: described oil groove is an X-shaped, and oil groove axially is provided with along sleeve body.
Of the present utility modelly further be set to: also be provided with the topping-up groove that axially is provided with along sleeve body on the described sleeve body, this topping-up groove runs through the sleeve body setting, and the edge of sleeve body two opening ends is provided with chamfering again.
The beneficial effects of the utility model are: set oil hole can make lubricant oil be distributed in equably on the surface of contact of sleeve body and axle on the sleeve body inwall, and unnecessary lubricant oil is stored in the oil hole, plays the effect of supplemental lubrication at any time; And the oil groove setting of X-shaped then can improve sleeve body to be sheathed on when spool last, and oil reserve between the two improves the lubrication effect and the sae number of axle sleeve; Being provided with of topping-up groove and chamfering all is from the sleeve body outside lubricant oil to be injected sleeve body inside for convenience, and be convenient and swift.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's a schematic representation.
Fig. 2 is the utility model embodiment's a sectional view.
Embodiment
As shown in Figure 1, 2, present embodiment comprises sleeve body 1 cylindraceous, this sleeve body 1 inwall is provided with a plurality of oil holes 11 that are used for oil storage, this oil hole 11 is distributed on the sleeve body 1 equably, also be provided with the oil groove 12 of X-shaped on sleeve body 1 inwall, this oil groove 12 has two and be symmetrically set on sleeve body 1 inwall, and oil groove 12 axially is provided with along sleeve body 1.Wherein, also be provided with the topping-up groove 13 that axially is provided with along sleeve body 1 on the described sleeve body 1, this topping-up groove 13 runs through sleeve body 1 and is provided with, the edge of two opening ends is provided with chamfering 14 on sleeve body 1 inwall, when sleeve body 1 is sheathed on when spool last, because the existence of chamfering 14, sleeve body 1 open end will produce between centers can be for the gap of topping-up.
In the utility model, set oil hole 11 can make lubricant oil be distributed in equably on the surface of contact of sleeve body 1 and axle on sleeve body 1 inwall, and unnecessary lubricant oil is stored in the oil hole 11, plays the effect of supplemental lubrication at any time; And the oil groove 12 of X-shaped is provided with, and then can improve sleeve body 1 and be sheathed on axle when last, oil reserve between the two, the lubrication effect and the sae number of raising axle sleeve; Being provided with of topping-up groove 13 and chamfering 14 all is from sleeve body 1 outside lubricant oil to be injected sleeve body 1 inside for convenience, and be convenient and swift.The utility model can also have other mode of executions, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
Claims (3)
