Description

A kind of the dynamic balancing technics method and combined moving of Carbon Fiber Composite Propeller Shaft pipe Balance clip
Technical field
The present invention relates to the dynamic balance fields of axis, and in particular to arrives a kind of realization carbon fibre composite central siphon dynamic balancing side Method is related to a kind of combined moving balance device for hooping.
Background technique
Carbon fibre composite is to use most wide one of composite material at present, there is very excellent mechanical property, it 1/4 of specific gravity less than steel, intensity is but much better than steel, therefore the use of carbon fibre composite is more and more wide.Use carbon 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 technical solution adopted in the present invention is as follows:
A kind of combined moving balance clip, including clip, bolt, nut, spring shim, clump weight and clump weight fixing screws; 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
The present invention will be further explained below with reference to the attached drawings, but is not limited to the following content.
Refering to fig. 1, of the invention a kind of to realize that clip involved by carbon fibre composite central siphon dynamic balance method is whole Body structure chart, including clip 1, bolt, nut and spring washer 5.Wherein, clip 1 is by four quadrant clips It forms, spring pad snare is being passed through adjacent two four points by bolt, nut and spring washer 5(between quadrant clip One of then fastened with nut on the bolt of circle clip) connect into a complete round clip 1.
(side of clip 1 or axial face) is uniformly arranged some threaded holes on the circumference of the complete circle clip 1 4(screw thread hole axle is parallel to clip axis), its number can be arranged in threaded hole 4 as needed.Correspondence is set on each threaded hole 4 There are fixing screws 3, fixing screws 3 can fasten clump weight 2 appropriate.
