Abstract
The present invention relates to a kind of mandrel, more particularly to a kind of cantilever rotating shaft.Outstanding part is taper, hollow equal strength axle outside described rotating shaft.First, the small space use of axle and installation requirement are solved；Secondly, effectively mitigate construction weight and alleviate axle body stress raisers；The fatigue life of axle is improved simultaneously.
Description
Technical field
The present invention relates to a kind of mandrel, more particularly to a kind of cantilever rotating shaft.
Background technology
Certain type machine weapon-bay gate operator is multistage opening mechanism, herein supporting and space deficiency and
Multiple rocking arms are needed to coordinate transmission.Original designs solid uiform section axle, and not only quality is larger and tired
During labor experiment fatigue crack is found in shaft shoulder root.
The content of the invention
The purpose of the present invention：It one kind be provided both can guarantee that to use and install in the case of insufficient space and want
Ask, and can improves the cantilever rotating shaft of anti-fatigue performance.
Technical scheme：A kind of cantilever rotating shaft, it is characterized in that：It is outstanding outside described rotating shaft
Part is taper, hollow equal strength axle.
One kind as the technical program is improved, and the outstanding part shaft shoulder passes through with spindle nose outside the rotating shaft
Arc transition is connected, and the surface of circular arc is polished by spreading.
Beneficial effects of the present invention：First, the small space use of axle and installation requirement are solved；Its
It is secondary, effectively mitigate construction weight and alleviate axle body stress raisers；Improve axle simultaneously
Fatigue life.
Brief description of the drawings
Fig. 1 installs and uses schematic diagram for the present invention's；
Fig. 2 is the structural representation of the present invention.
In figure：1 it is rotating shaft, 2 be airframe structure, 3 be support arm, 4 be connecting bolt, 5 is
Bolt, 101 be axle journal, 102 be axle body, 103 be flange, 104 be middle axle body, 105 be
Spindle nose, 106 are axle journal.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
Traditional mechanism rocker arm shaft generally use typical case both ends supporting construction.Due to being limited using space,
One end supporting cantilever rotating shaft must be used.Cantilevered support structure has the fatiguability especially strong point
Or at the abrupt change of cross-section, the shortcomings of bearing capacity is small in the case of same section, amount of deflection is big.The present invention
The shortcomings that overcoming cantilevered support structure, meet use, installation requirement.
Cantilever axle body uses taper strength structure in the present invention, avoids the mutation of axle section, and eliminating should
Power is concentrated, and improves the fatigue strength of axle.
Axle body uses hollow-core construction in the present invention, makes full use of material, in the situation of equivalent material
Under improve the bearing capacity of axle, reduce deflection deformation amount.
The necessary abrupt change of cross-section area increase excessive circular of axle body in the present invention, and its surface is carried out
Spreading polishes, and effectively increases the fatigue strength in cantilevered axle abrupt change of cross-section area.
The present invention is to realize the above by mode in detail below：A kind of cantilever rotating shaft is hollow
Tapered shaft 1 is by bolt 4 end-journal 101, axle body 102 and flange 103 and airframe structure
2 connections；Spindle nose 105 is connected with support arm bearing 3, is connected by bolt 5 and axle journal 106
Connect compression；Middle axle body 104 forms cantilever design with spindle nose 105, axle journal 106.Wherein.It is empty
End-journal 101, axle body 102, flange 103, the middle axle body 104 of heart tapered shaft 1 are sky
Mandrel effectively mitigates construction weight；Wherein middle axle body 104 reduces axle using conical equal strength axle
Body stress concentration；Other spindle nose 105 and the middle root of the 104 joint portion shaft shoulder of axle body 107 use compared with
Big excessively fillet and surface spreading polishing is carried out, improve the anti-fatigue performance of axle.
