Abstract
The utility model relates to a shaft sleeve structure, which comprises a hollow barrel-shaped body, the barrel-shaped body is provided with an oil hole, an oil groove is arranged on the inner wall of the barrel-shaped body along the circumferential direction, and a notch is arranged on the outer surface of the barrel-shaped body. The shaft sleeve structure has the advantages of greatly improving abrasion resistance of a shaft sleeve, simultaneously saving energy consumption, reducing deflections to the greatest extent under different temperature differences, further avoiding difficulties caused by mounting and using of products, saving production cost and improving effect.
Description
Technical field
The utility model relates to a kind of adapting device of mechanical axis, relates in particular to a kind of axle sleeve structure.
Background technique
Existing what take turns that stern shaft and overcoat friction place use is alloy material, and this material price is high, and the rate of wear is fast, and along with the wearing and tearing of alloy material; Tailing axle concussion aggravation causes foot unstable, moreover, because the concussion of tailing axle aggravation; The causes water gland breaks, and causes the cabin to leak, and for these reasons, this alloy material is general only must be changed with 1-2; And because the surface friction drag of alloy material and tailing axle is bigger, the steamer power consumption also strengthens thereupon.
The model utility content
In order to overcome above defective, the technical problem that the utility model will solve is: a kind of resistance of not only reducing friction is provided, and axle sleeve structure cheap, that can increase the service life.
The technological scheme that the utility model adopted is: a kind of axle sleeve structure; The tubular body that comprises hollow; Said tubular body is provided with oilhole, along the circumferential direction is provided with oil groove on the inwall of said tubular body, and the outer surface of said cylindrical body is provided with a breach.
In preferred embodiment of the utility model, what axle sleeve structure further comprised said oil groove is shaped as rhombus, dendriform or annular.
In preferred embodiment of the utility model, axle sleeve structure comprises that further the inwall of said tubular body is provided with the oil hole.
In preferred embodiment of the utility model, axle sleeve structure comprises that further said tubular body is through Overheating Treatment.
The beneficial effect of the utility model is: the wear resistance that has improved axle sleeve greatly; Saved energy consumption simultaneously, the amount of deformation that can under the different temperature difference, be produced to greatest extent, thus avoid the installation of product and the difficulty that use brings; Practice thrift cost of production, improved effect.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Among the figure: 1, tubular body, 2, oilhole, 3, oil groove, 4, breach, 5, You Keng.
Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of axle sleeve structure comprises the tubular body 1 of hollow; Said tubular body 1 is provided with oilhole 2; Along the circumferential direction be provided with oil groove 3 on the inwall of said tubular body 1, the outer surface of said cylindrical body 1 is provided with a breach 4, is convenient to installation and removal.
Further, the preferred said oil groove of the utility model be shaped as rhombus, the lubricant oil that keeps being injected into circulates at tubular body 1 inwall, thereby improves the lubricant oil skewness and the inclined to one side phenomenon of mill that causes.But be not limited to rhombus, can also be dendriform or annular etc.
In order to store grease, prolong refueling time, the inwall of said tubular body 1 is provided with oil hole 5, has realized good oil storage effect.
Further, said tubular body 1 can be Carburization Treatment through Overheating Treatment, has strengthened the wear resistance of tubular body 1.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
Claims (4)
1. axle sleeve structure comprises the tubular body of hollow, and said tubular body is provided with oilhole, it is characterized in that: along the circumferential direction be provided with oil groove on the inwall of said tubular body, the outer surface of said cylindrical body is provided with a breach.
