Abstract
A kind of turbo-expander rotating spindle structure, it includes the expanding machine active wheel and supercharger impeller that a rotating spindle is fixedly connected with two ends, described expanding machine active wheel and supercharger impeller are interference fitted by the triangle taper hole and the triangle axis of cone that rotating spindle two ends are set at axle center respectively, and constitute a rigid rotator by least one bolt connection in shaft end；The bolt hole of the rotating spindle two axial ends is respectively left-handed screw and dextrorotation screw, and is each configured with left-hand bolt and right-hand bolt；It has simple in construction, easy to install and use, good reliability, there is enough intensity and fastness, the features such as service life is greatly improved.
Description
Technical field
The utility model relates to a kind of turbo-expander rotating spindle structure, belong to turbo-expander technical field.
Background technology
Rotor is the assembly of turbo-expander rotating part, is mainly made up of rotating spindle, impeller etc..The one of rotating spindle
Active wheel of the end equipped with expanding machine, the other end is equipped with supercharger impeller.Two ends due to rotating spindle and expansion in the prior art
Connection between machine active wheel and supercharger impeller uses straight shell type attachment structure, thus fixed connection structure fastness is not enough,
Easily the security incident such as fall off in real work, there is the potential safety hazard of impeller operation.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of simple in construction, uses peace
Dress is convenient, and good reliability has enough intensity and fastness, the turbo-expander rotating spindle structure that service life is greatly improved.
The purpose of this utility model is completed by following technical solution, a kind of turbo-expander rotating spindle knot
Structure, it includes the expanding machine active wheel and supercharger impeller that a rotating spindle is fixedly connected with two ends, described expanding machine work
Make wheel and supercharger impeller to be interference fitted by the triangle taper hole and the triangle axis of cone that rotating spindle two ends are set at axle center respectively,
And a rigid rotator is constituted by least one bolt connection in shaft end.
As preferred：The bolt hole of the rotating spindle two axial ends is respectively left-handed screw and dextrorotation screw, and is matched somebody with somebody respectively
It is equipped with left-hand bolt and right-hand bolt.
The utility model, which belongs to, to be improved one kind of prior art, and it has simple in construction, easy to install and use, reliability
It is good, there are enough intensity and fastness, the features such as service life is greatly improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is blade wheel structure schematic diagram described in the utility model.
Fig. 3 is the end view of triangle taper hole described in the utility model.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing：Shown in Fig. 1-3, one kind described in the utility model
Turbo-expander rotating spindle structure, it includes expanding machine active wheel 2 and the supercharging that a rotating spindle 1 is fixedly connected with two ends
Machine impeller 3, described expanding machine active wheel 2 and supercharger impeller 3 pass through the triangle taper hole 4 and rotating spindle 1 at axle center respectively
The triangle axis of cone 5 that two ends are set is interference fitted, and passes through at least one bolt 6 connection one rigid rotator of composition in shaft end.
The bolt hole of the two axial ends of rotating spindle 1 described in the utility model is respectively left-handed screw and dextrorotation screw, and is distinguished
It is configured with left-hand bolt and right-hand bolt.Wherein the end of expanding machine active wheel 2 uses right-hand bolt, and the end of supercharger impeller 3 is used
Left-hand bolt.Protecting casing 7 is also configured with the both ends of rotating spindle 1.
Embodiment：Impeller described in the utility model is coupled by triangle taper hole 4 and two bolts 6 with rotating spindle 1
It is coupled, constitutes a rigid rotator.Rotating spindle 1 connects through triangle taper hole with impeller, and the two is interference fit, need pair during assembling
Impeller carries out heating assembling, makes in expanding machine running, impeller will not relatively rotate with main shaft.
The bolt hole at the two ends of rotating spindle 1 described in the utility model is respectively left-handed and right-handed screw, and wheel rotation rises
After coming, the coupling bolt of impeller and main shaft is more and more tighter, will not fall off；Further strengthen impeller operation safety and
Stationarity.
