The central siphon that fibrous composite is fabricated to replaces traditional metal shaft, can not only meet intensity requirement, and can reduce biography
The quality of moving axis, advantageously reduces energy loss.
In carbon fibre composite central siphon manufacturing process, the problems such as due to material unevenness and the accuracy of manufacture, central siphon can be made
The mass center line of upper each cross section is not overlapped with central siphon geometric center lines, when the rotation of carbon fibre composite central siphon, axis it is dynamic not
Balance can cause the oscillation crosswise of shaft；When revolving speed is higher, even if very small mass eccentricity can all generate very big centrifugation
Power makes central siphon generate strong vibration, it is therefore desirable to carry out dynamic balancing technics processing to carbon fibre composite central siphon.
Currently, metal shaft, which does dynamic balancing, two methods of duplicate removal and weight gain, it is general to be realized by drilling and welding.Both
Method cannot all use on carbon fibre composite central siphon, and drilling can destroy fiber, reduce the mechanical property of central siphon, and stickup is matched
Pouring weight, when running at high speed, counterweight has the risk thrown away.The present invention passes through interference fit and axis by mechanical connection, with clip
Pipe connection realizes the dynamic balancing of carbon fibre composite central siphon by adjusting the clump weight on clip, and it is multiple will not to destroy carbon fiber
The globality of the material of condensation material central siphon, easy to process, easy to operate, safety is good, high reliablity.
Summary of the invention
It is an object of that present invention to provide a kind of realization carbon fibre composite central siphon dynamic balance methods and combined moving to balance
Device for hooping.This method is easy to operate, solves carbon fibre composite central siphon dynamic equilibrium problems, enables axis normal table work
Make.

The clip is enclosed by 4 1/4 round clips, is connected by bolt, nut with spring washer between 1/4 circle clip,
And a complete round clip can be formed in the circumferential of Carbon Fiber Composite Propeller Shaft pipe；The side of the clip is uniformly divided
It is furnished with the threaded hole for passing through screw fixed weight block, clump weight has through-hole corresponding with threaded hole, and fixing screws pass through
The through-hole of clump weight is threadedly coupled with threaded hole.
The present invention also provides a kind of dynamic balancing technics methods for realizing Carbon Fiber Composite Propeller Shaft pipe, will include card
The combined moving of hoop and clump weight balance clip is fixedly connected in Carbon Fiber Composite Propeller Shaft, by increasing counterweight one by one
Clump weight is removably fixed on clip different location by the mode of the number of block, until realizing carbon fibre composite
Axis dynamic balancing；It is passed alternatively, the combined moving balance clip including clip and clump weight is fixedly connected on carbon fibre composite
On moving axis, clump weight is removably fixed on clip different location, by way of reducing the number of clump weight one by one,
Until realizing the dynamic balancing of carbon fibre composite axis.
The present invention is uniformly arranged several threaded holes on clip, and clump weight has through-hole corresponding with threaded hole；It is described
Clump weight is removably fixed on clip different location to refer to, by the through-hole alignment threaded hole of clump weight, using fixation
The through-hole that screw passes through clump weight is threadedly coupled with threaded hole.
The threaded hole is distributed in the side of clip.
The clip is enclosed by 4 1/4 round clips, by bolt, nut and spring pad between 1/4 circle clip
Circle connection, circumferential in carbon fibre composite axis form a complete round clip.
Clump weight can be installed according to dynamic balancing measurement result on threaded hole of the present invention.
Beneficial effects of the present invention are as follows:
1) present invention provides a kind of realization carbon fibre composite central siphon dynamic balance method, metal clip processing technology thereof letter
Single, dynamic balance weight block is realized by mechanical connection, is avoided cementing insecure.
2) globality that will not destroy carbon fibre composite central siphon material, will not change the mechanical property of axis.
3) reach balance, strong operability, high reliablity with the method for increasing and decreasing or changing clump weight axial and circumferential position.
4) Combined clip is utilized, the method that duplicate removal can also be used in weight increasing method both can be used, dynamic balancing is implemented to axis.
The dynamic balance method, using Combined clip, structure is simple, easy to operate, can facilitate realization carbon fiber composite
Expect the dynamic balancing of central siphon.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
