Abstract
An improved shaft sleeve belongs to the field of mechanical parts. The improved shaft sleeve comprises a cylindrical body, wherein a plurality of axial grooves are formed in the inner hole wall of the cylindrical body, slopes are arranged on the edges of the axial grooves, one ends of the axial grooves penetrate through the end surface of one end of the cylindrical body, an end cover is fixed and covered on the end surface of the end, a threading hole of the same inner diameter with the axial sleeve is formed in the end cover so as to enable the axis line of the threading hole of the end cover to be consistent with the inner hole axis line of the cylindrical body, the other ends of the axial grooves are arranged on the inner hole wall of the cylindrical body, an annular groove is formed in the outer circle surface of the cylindrical body, and a plurality of through holes which are respectively communicated with the axial grooves are respectively formed in the inner bottom surface of the annular groove. Through the arrangement of the axial grooves in the shaft sleeve and the arrangement of the slopes on the edges of the axial grooves, lubricating oil can be fully fed between the inner wall surface of the shaft sleeve and a rotating shaft, the structure is simple, the lubricating effect is great, and the adding of lubricating oil is convenient. Besides, the axial grooves do not need to be twice processed, the forming of the axial grooves and the molding of the cylindrical body can be finished together, and the processing cost is lowered.
Description
Technical field
The utility model belongs to component of machine field, especially relevant with a kind of improved type axle sleeve.
Background technique
Axle sleeve is arranged in rotating shaft conventionally and countershaft shields, and due in rotating shaft rotation process, rotating shaft and axle sleeve, supporting the use in process in continuous frictional rotation, therefore, need to guarantee sufficient lubrication between axle sleeve and rotating shaft.At present, general employing added lubricant oil between axle sleeve and rotating shaft, owing to lubricant oil need to being added on the inside surface of contact between rotating shaft and axle sleeve, so add toward inner again after rotating shaft and axle sleeve need to being split while adding, make to add lubricant oil operation loaded down with trivial details, inconvenient operation, for improving above-mentioned defect, in prior art, have by radial groove is set on sleeve lining, and through hole is set on axle sleeve is communicated with groove, from through hole, add lubricant oil, by the groove on sleeve lining, lubricant oil is entered between sleeve lining face and rotating shaft, reach lubrication effect, although the structure of this axle sleeve can improve lubrication effect and add simple to operateization of lubricant oil, but the processing of the radial groove in axle sleeve more complicated, axle sleeve basis can not complete when body formed together, need secondary operations, increased cost of production.
Model utility content
The purpose of this utility model is intended to overcome existing axle sleeve and has above-mentioned defect, and a kind of improved type axle sleeve of simple in structure, easy to process, high lubricating effect is provided.
For this reason, the utility model is by the following technical solutions: a kind of improved type axle sleeve, comprise cylindric body, it is characterized in that, on described cylindric body inner hole wall, be provided with several axial notches, the edge of axial notch is provided with inclined-plane, axial notch one end connects cylindric body one end end face, and this end end face upper cover is equipped with an end cap, end cap is provided with the perforation consistent with sleeve diameter, end cap is fixedly connected with by screw with cylindric body, make the shaft axis of end cap perforation consistent with described cylindric body endoporus shaft axis, the axial notch the other end is positioned on cylindric body inner hole wall, on described cylindric body periphery, be provided with annular groove, on annular groove inner bottom surface, be provided with multiple through holes that are communicated with described axial notch respectively.During use, rotating shaft is threaded onto on inner hole of shaft sleeve wall, in through hole, add lubricant oil, lubricant oil is entered in axial notch, and in rotating shaft rotation process, the lubricant oil in axial notch flow between sleeve lining face and rotating shaft by the inclined-plane at axial notch edge, effectively play lubrication, by end cap is set, can prevent that lubricant oil from flowing away from cylindric body end, make axial notch play oil storage effect.
Use the utility model can reach following beneficial effect: by axial notch is set in axle sleeve, and at axial notch edge, inclined-plane is set, lubricant oil can fully be entered between sleeve lining face and rotating shaft, simple in structure, high lubricating effect, adds lubricant oil convenient; And axial notch do not need secondary operations, cylindric can complete together when body formed, reduce processing cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model axial section schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, the utility model comprises cylindric body 1, on cylindric body 1 inner hole wall, be provided with several axial notches 5, the edge of axial notch 5 is provided with inclined-plane, facilitate lubricant oil to enter between sleeve lining face and rotating shaft from inclined-plane, axial notch 5 one end connect cylindric body 1 one end end face, and this end end face upper cover is equipped with an end cap 3, end cap 3 is provided with the perforation consistent with sleeve diameter, end cap 3 is fixedly connected with by screw with cylindric body 1, the shaft axis that end cap 3 is bored a hole is consistent with described cylindric body 1 endoporus shaft axis, axial notch 5 the other ends are positioned on cylindric body 1 inner hole wall, on described cylindric body 1 periphery, be provided with annular groove 2, on annular groove 2 inner bottom surfaces, be provided with multiple through holes 4 that are communicated with described axial notch 5 respectively.During use, rotating shaft is threaded onto on inner hole of shaft sleeve wall, toward the interior interpolation lubricant oil of through hole 4, lubricant oil is entered in axial notch 5, and in rotating shaft rotation process, the lubricant oil in axial notch 5 flow between sleeve lining face and rotating shaft by the inclined-plane at axial notch 5 edges, effectively play lubrication, by end cap 3 is set, can prevent that lubricant oil from flowing away from cylindric body 1 end, makes axial notch 5 play oil storage effect.
