Description
Technical field
Compressor field is the utility model is related to, relates in particular to a kind of simple locking dress of Centrufugal compressor impeller
Put.
Background technology
At present, Centrufugal compressor impeller uses doubly linked structure more, and be fastenedly connected for using pretension bolt
Structure, how to ensure to reach expected coupling mechanism force in technique, turn into the problem of assembly technology.Traditional process is to exert oneself
Square spanner tightens locking nut, and this method operation is laborious, and the size of pretightning force is not easy to hold, and easily causes locking screw
Cooperation tension between female and impeller axle was pine.
In order to solve the above-mentioned technical problem, Chinese patent notification number was the prior art of " CN201377466 " in 2010
January 6 disclosed a kind of locking device for centrifugal compressor impeller, and its technical scheme is：The impeller includes impeller axle
And the locking nut in impeller axle is threadedly connected to, especially, locking device includes：Piston, its one end are connected through a screw thread
To impeller axle and relative with locking nut；Driving instrument, it is connected with piston, drives piston movement to stretch or discharge impeller axle,
And driving lever, coordinate with locking nut, for tightening locking nut when stretching impeller axle.In actual use, this is special
Although profit can relatively accurately reach expected coupling mechanism force, it is complex and unhandy scarce that it remains structure
Fall into.
Utility model content
The purpose of this utility model is solve the above-mentioned problems in the prior art, there is provided a kind of centrifugal compressor leaf
The simple locking device of wheel, the utility model solve the complicated and unhandy problem of locking device structure in the prior art.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of simple locking device of Centrufugal compressor impeller, it is characterised in that：Including pedestal, push rod and nut is extruded,
The through hole being adapted with impeller axle external diameter is provided with the pedestal, the pedestal is movably set in impeller axle by through hole,
One end of the push rod is fixed on the side of pedestal, and the other end is fixedly installed the jacking block for acting on impeller, the extruding nut
It is threaded in the impeller axle of pedestal opposite side, the extruding nut and the jacking block being connected on pedestal coordinate stretching impeller
Axle.
Plastic cushion is fixedly installed on the jacking block.
The jacking block is bolted on push rod.
The jacking block is square or circular.
The quantity of the push rod is 2-4.
The push rod is cylinder.
Using the utility model has the advantage of：
First, the utility model is coordinated to stretch impeller axle by the jacking block for extruding nut and being connected on pedestal, utilizes leaf
The elastic deformation of wheel shaft ensures to reach expected coupling mechanism force, has both improved the fixed effect of impeller axle, have again it is simple in construction,
The advantages that easy to operate, solves the complicated and unhandy problem of locking device structure in the prior art.
2nd, the plastic cushion that the utility model is set on jacking block can reduce the frictional force of jacking block and impeller, avoid pair
Cause to damage in the surface of impeller.
3rd, jacking block is fixed on the structure on push rod by the way of bolt fixation in the utility model, is advantageous to according to reality
When need to change different jacking blocks, more convenient operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure marked as：1st, pedestal, 2, push rod, 3, extruding nut, 4, jacking block, 5, plastic cushion, 6, impeller, 7, impeller
Axle.
Embodiment
A kind of simple locking device of Centrufugal compressor impeller, including pedestal 1, push rod 2 and extruding nut 3, the pedestal 1
On be provided with the through hole being adapted with the external diameter of impeller axle 7, the pedestal 1 is movably set in impeller axle 7 by through hole, the top
One end of bar 2 is fixed on the side of pedestal 1, and the other end is fixedly installed the jacking block 4 for acting on impeller 6, the extruding spiral shell of nut 3
Line is connected in the impeller axle 7 of the opposite side of pedestal 1, and the extruding nut 3 and the jacking block 4 being connected on pedestal 1 coordinate stretching leaf
Wheel shaft 7.
In the utility model, for convenient disassembly, the jacking block 4 is bolted on push rod 2.In order to reduce jacking block
4 act on frictional force during impeller 6, and plastic cushion 5 is fixedly installed on the jacking block 4.
In the utility model, the jacking block 4 is square or circular.
In the utility model, the quantity of the push rod 2 is 2-4, and the push rod 2 is cylinder.
Implementation principle of the present utility model is：
Pedestal 1 is set in impeller axle 7 first, and the plastic cushion 5 on jacking block 4 is contacted with impeller 6, then will be squeezed
Pressure nut 3 is set in impeller axle 7, and continues to stir extruding nut 3, and extruding nut 3 produces extruding force to pedestal 1, extruded
In the presence of power, due to push rod 2 and jacking block 4, impeller axle 7 is stretched, and after being stretched to setting position, dials tight locking screw
Mother, then the stretch section resilience of extruding extruding nut 3, now impeller axle 7 is unclamped, but the shaft part after locking nut locking can not be complete
Resilience, such impeller axle 7 elastic stretching amount of itself can produce pretightning force to locking nut, so as to reach the work of impeller locking 6
With.
