Description
Technical field
This utility model relates to axle sleeve technical field, is specifically related to a kind of durable axle sleeve.
Background technology
Axle sleeve is in During Process of Long-term Operation, and journal surface, by the extruding force of expansion set and acting on of composite machine power, will cause its permanent deformation, diameter or reduction 0.1mm ~ 0.3mm.And then cause mechanical expansion tight fit dynamics not reach the power that tightens of requirement, fit clearance occurs between axle sleeve and main shaft, causes the abrasion of axle sleeve.
The endoporus oil storage of seamless shaft sleeve and lubricating system typically use variously-shaped oil groove, blind hole to come oil storage, cloth oil, but each blind hole of sleeve lining is mutually isolated, oil groove oil reserve is limited, be likely to result in cloth oil, oil storage uneven, form large-area lubrication blind area, it is easy to make axle sleeve and axle be engaged, thus cause the service life reducing axle sleeve, in use need frequent maintenance.
The seamless shaft sleeve of prior art is solid bearing bush, and without buffering, service life is short, causes use cost higher.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction, a kind of durable axle sleeve reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises outer shaft, internal axle sleeve, outer groove, outer shaft oil filler point, inner groove, internal axle sleeve oil filler point, arc groove, conduit through hole；Described outer shaft and internal axle sleeve interference fit；Described outer shaft outer wall is provided with outer groove；The inwall of described internal axle sleeve is provided with inner groove；Described outer shaft and the axial wall of internal axle sleeve are respectively arranged with the outer shaft oil filler point and internal axle sleeve oil filler point communicated；It is provided with arc groove on the outer groove of one end of described outer shaft oil filler point；Described internal axle sleeve inwall is provided with some conduit through holes.
As preferably, described conduit through hole becomes 30 ~ 45 ° with the axis angle of internal axle sleeve.
As preferably, described outer shaft oil filler point is consistent with the diameter of internal axle sleeve oil filler point.
Operation principle of the present utility model is: internal axle sleeve can play cushioning effect, alleviates the stress of outer shaft, thus improves the service life of outer shaft and internal axle sleeve, and the processing of conduit through hole is more convenient, and internal axle sleeve is detachable, maintains easily.
After using said structure, what this utility model produced has the beneficial effect that a kind of durable axle sleeve described in the utility model, and service life, short length, detachably, safeguarded that use cost is low, and this utility model has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low.

Detailed description of the invention
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Referring to as shown in Fig. 1 Fig. 2, this detailed description of the invention adopts the following technical scheme that it comprises outer shaft 1, internal axle sleeve 2, outer groove 3, outer shaft oil filler point 4, inner groove 5, internal axle sleeve oil filler point 6, arc groove 7, conduit through hole 8；Described outer shaft 1 and internal axle sleeve 2 interference fit；Described outer shaft 1 outer wall is provided with outer groove 3；The inwall of described internal axle sleeve 2 is provided with inner groove 5；Described outer shaft 1 and the axial wall of internal axle sleeve 2 are respectively arranged with the outer shaft oil filler point 4 and internal axle sleeve oil filler point 6 communicated；It is provided with arc groove 7 on the outer groove 3 of one end of described outer shaft oil filler point 4；Described internal axle sleeve 2 inwall is provided with some conduit through holes 8.
As preferably, described conduit through hole 8 becomes 30 ~ 45 ° with the axis angle of internal axle sleeve 2.
As preferably, described outer shaft oil filler point 4 is consistent with the diameter of internal axle sleeve oil filler point 6.
The operation principle of this detailed description of the invention is: internal axle sleeve 2 can play cushioning effect, alleviates the stress of outer shaft 1, thus improves outer shaft 1 and the service life of internal axle sleeve 2, and the processing of conduit through hole 8 is more convenient, and internal axle sleeve 2 is detachable, maintains easily.
After using said structure, this detailed description of the invention produce a kind of durable axle sleeve having the beneficial effect that described in this detailed description of the invention, service life short length, detachably, safeguarding that use cost is low, this detailed description of the invention has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
