Abstract
The utility model is a kind of expansion sleeve, the outer cone joint surface of outer cone axle sleeve is socketed the inner cone joint surface of the inner cone axle sleeve, the inner surface of outer cone axle sleeve, outer cone joint surface and the inner cone joint surface of inner cone axle sleeve are provided with the straight slot being inserted into for positioning key, when the outer cone axle sleeve and the inner cone axle sleeve mutually cover access axis, bolt is circumferentially fastened on outer cone axle sleeve and inner cone shaft room, the outer cone joint surface of the outer cone axle sleeve abuts the inner cone joint surface of the inner cone axle sleeve, the straight slot intercombination of the two is formed through a locating slot almost the same with positioning key shape at this time, the one side of the positioning key abuts axis surface.
Description
Technical field
The utility model is related to a kind of connector sleeves, are specifically a kind of expansion sleeves, belong to machine driving ancillary equipment neck
Domain.
Background technology
Swelling connection is that expansion connecting sleeve that is a pair of or counting internal male cone (strobilus masculinus) fitting is placed between axis and wheel bore（One
As be referred to as expansion sleeve or expansion set）, under responsive to axial force, inner ring reduces, and outer shroud swells, fitted closely with axis and wheel hub, generates
Enough frictional force is done, to transmit the combined load of torque, axial force either the two.
The centering performance of swelling connection is good, and dismounting or the relative position of adjustment axis and wheel hub are convenient, without stress concentration, hold
Loading capability is high, can avoid weakening part strength because of keyway reason, and have sealing function.
But since general expansion sleeve inner cone axle sleeve aperture differs larger with the outer diameter of external conical sleeve, lead to same expansion sleeve and axis
It is larger with the transmission torque difference of wheel hub, reduce the bearing capacity of expansion sleeve.
Being disclosed in the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or imply that the information is constituted in any form.
Utility model content
The technical issues of the utility model is solved is to provide a kind of expansion sleeve of raising and axis driving torque ability.
The utility model patent is achieved through the following technical solutions：
A kind of expansion sleeve, including the inner cone axle sleeve and outer cone axle sleeve that are mutually axially socketed, it is characterised in that：The outer axis of cone
It covers one end and is equipped with overhanging outer cone joint surface, the inner ring of the inner cone axle sleeve is equipped with inner cone compatible with the outer cone joint surface
Joint surface, the inner cone joint surface of the inner surface of outer cone axle sleeve, outer cone joint surface and inner cone axle sleeve be provided be inserted into for positioning key it is logical
Slot, when the outer cone axle sleeve and the inner cone axle sleeve mutually covers the when of accessing axis, bolt is circumferentially fastened on outer cone axle sleeve and the interior axis of cone
Inner room, the outer cone axle sleeve to abut the inner cone joint surface of the inner cone axle sleeve, straight slot both at this time mutual on outer cone joint surface
Combination is formed through a locating slot almost the same with positioning key shape, the one side of the positioning key abuts axis surface.
The technical solution that the utility model further limits is：
Further, the straight slot of the outer cone axle sleeve is both ends open slot, specially：Inner surface is axially penetrated through along it and is inserted
Connect the outer surface at end；The straight slot of the inner cone axle sleeve is one end open slot, specially：Along its inserted terminal inner ring into its other side
It stretches and is no more than the other end.
Further, the positioning key is flat key, the straight slot intercombination breakthrough form of the outer cone axle sleeve and inner cone axle sleeve
At the closed locating slot in one end, the cavity shape of the locating slot is consistent with the shape of positioning key.
Further, axially overhanging length is more than the inner cone of the inner cone axle sleeve on the outer cone joint surface of the outer cone axle sleeve
Joint surface axial length.
The beneficial effects of the utility model are：Outer cone axle sleeve is connect with flat key simultaneously with inner cone axle sleeve, increases carrying energy
Power ensure that its sealing function because the straight slot of inner cone axle sleeve is obstructed, can be used for transmitting the big occasion of load.
Description of the drawings
Fig. 1 is the sectional structure chart of the utility model；
Fig. 2 is Figure 1A-A to sectional view.
In figure：Outer cone axle sleeve 1, inner cone axle sleeve 2, hexagon socket head cap screw 3, flat key 4.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be apparent to, in conjunction with
Attached drawing is expanded on further how the utility model patent is implemented：
The utility model is as depicted in figs. 1 and 2, and by inner cone axle sleeve 2, outer cone axle sleeve 1, hexagon socket head cap screw 3 forms；The outer axis of cone
Set 1 is compressed with the hexagon socket head cap screw 3 of inner cone axle sleeve 2, and axially overhanging length is more than the interior axis of cone for the outer cone joint surface of outer cone axle sleeve 1
The inner cone joint surface axial length of set 2, because faying face is longer, energy automatic centering, the straight slot of outer cone axle sleeve 1 and inner cone axle sleeve 2
Intercombination is formed through the closed locating slot in one end, flat key 4 is inserted into from 1 side of outer cone axle sleeve in locating slot, at this time flat key 4
One side abut the surface of axis, in addition three faces abut locating slot respectively, the design change it is original rely solely on face and face it
Between frictional force secured mode, increase bearing capacity, because the keyway of inner cone axle sleeve 2 is obstructed, ensure that its sealing function, can
The occasion big for transmitting load.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out very much
Change and variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle and in fact of the present invention
Border is applied, so that those skilled in the art can realize and utilize a variety of different exemplary implementation schemes of the present invention
And various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
