Abstract
The invention discloses a multistage electric shaft generally comprising a mandrel, driving sections, driven sections, and a connecting wire. The driving sections and the driven sections of the multistage electric shaft are installed on the mandrel. Each driving section is a motor equipped with an outer rotor and an inner stator. Each driven section is a cylindrical cavity. When the multistage electric shaft operates, the mandrel does not rotate but the driving stages and the driven stages rotate.
Description
Technical field
The present invention relates to electric drive axle, particularly relate to a kind of multisection type electric drive axle.
Background technology
Now in the industrial production, conveyer plays important role always.Simple conveyer adds crawler belt by two axles at two ends and forms.One of them axle general is driving shaft, and one is driven shaft, and driving shaft is connected with external motive device by drive disk assembly.Also having some driving shafts not need external motive device, as electric drum, itself is exactly the rotor of motor.
Can produce vibration in conveyer operation process, and often rotating speed is higher, transport tape breadth wider (axle is longer) vibration is more serious.Vibration can affect service life of a machine, and the serious machine that even can cause cannot work.Integrally, its vibration causes primarily of axle conveyer.There is absolute axisymmetric axle, during rotation, can not vibration be caused.If axle has the defect in certain bending or other processing, cause its barycenter off-axis, during rotation, will vibration be brought.
Need wide cut, high-speed transfer machine in some application, improve breadth width and the transmission speed of conveyer, first problems faced vibrates aggravation exactly! Reducing the most direct also the most effective means of vibration is improve the machining accuracy of axle, makes axle more close to axial symmetry.This often makes processing cost significantly improve.Some are used to the occasion of slender axles, even machining is very superior, axle is meeting flexural deformation under the tension force effect of crawler belt, and the axoplasm heart can off-axis.
There is disclosed technology at present, the driven shaft of conveyer is made segmented.This kind of axle has a fixing mandrel, and mandrel is installed multiple bearing, and in conveyer running, crawler belt band dynamic bearing rotates.Like this, during work, mandrel does not turn, and each section of bearing just mandrel overlapped turns, even if to occur to a certain degree bending for mandrel, also can not cause obvious vibration.This scheme effectively reduces the vibration that in the conveyer course of work, driven shaft causes, but the vibration problem that driving shaft causes cannot solve simply by this scheme.Relative to driven shaft, the vibration that driving shaft causes is often larger, and the difficulty reducing the vibration that driving shaft causes is also larger.
Summary of the invention
In order to the vibration caused when reducing axle running, improve the transmission speed of crawler belt, the present invention proposes a kind of new solution.
Main technical schemes of the present invention is as follows:
A kind of multisection type electric drive axle, it comprises a mandrel, two or more axle sleeves.Some section in these axle sleeves has the function of motor, containing rotor, stator, is called powered phase; Other Duan Ze does not have the function of motor, is only plain shaft cover, is called driven section.As required, all sections of a multisection type electric drive axle can be powered phase; Also can some powered phase, driven section an of part.But have at least one section to be powered phase.If its all sections is all powered phase, the stator of powered phase can be utilized to be spliced into mandrel, and not need an extra whole mandrel.As required, each powered phase can arrange speed feedback device, in order to control the rotating speed consistency of each powered phase.
Compared with prior art, the advantage of described multisection type electric drive axle is: one, compared with the driving shaft mentioned in background technology, the rotor of the driving shaft that this programme proposes adopts segment design, during work, mandrel does not turn, and each section of rotor rotates around each self-corresponding a bit of mandrel, significantly reduces the vibration that the flexural deformation due to mandrel brings, the requirement on machining accuracy of axle is significantly reduced, is conducive to the speed improving transport tape; Two, compared with the segmented driven shaft mentioned with background technology, the axle self that this programme proposes can provide power.

Embodiment
Describe the multisection type electric drive axle of the technical program embodiment with reference to the accompanying drawings in detail.
With reference to Fig. 1, the technical program first embodiment provides a kind of existing powered phase also to have the multisection type electric drive axle of driven section.This electric drive axle is divided into 5 sections, comprises two powered phases 1, three driven section 2, and powered phase 1 is alternately arranged on mandrel 5 with driven section 2.Each powered phase 1 is as a complete motor, and containing independently stator 3 and rotor 4, its stator 3 is fixed on mandrel 5, and the connection wire 6 of stator winding arrives the external world through mandrel 5; Driven section 2 is one section of columniform cavity, and its two ends are arranged on mandrel 5 simply by bearing.Powered phase 1 is identical with the external diameter of driven section 2.In actual use procedure, this multisection type electric drive axle, as a driving shaft, forms a conveyer together with an other driven shaft and crawler belt.After energising, the powered phase 1 of driving shaft starts to drive crawler belt, and then drives driven section 2 running, and drives driven shaft to operate together further, realizes the function of conveyer.
With reference to Fig. 2, the technical program second embodiment provides the multisection type electric drive axle that a kind of existing powered phase 1 also has driven section 7.This electric drive axle comprises two powered phases 1 and 11 driven section 7.This powered phase is identical with the powered phase in the first embodiment.Driven section is then a bearing.Operating principle and the first embodiment similar.
With reference to Fig. 3, it is all the multisection type electric drive axle of powered phase 1 that the technical program the 3rd embodiment provides a kind of.This electric drive axle comprises four powered phases.During work, four powered phases 1 drive crawler belt running jointly.
Be appreciated that any one embodiment above-mentioned, quantity and the arrangement mode of its powered phase and driven section can be arbitrary.Each driven section on an axle can adopt same form, also can adopt multi-form, and such as, on same axis some driven section adopts cylindrical cavity, and some driven section is exactly a simple bearing.Certainly, each powered phase on same axis also can adopt different forms.
Be appreciated that any one embodiment above-mentioned, the stator 3 in its powered phase, rotor 4 can be, but not limited to be conductor winding, also can be permanent magnets.
If wished, mandrel also can be that multistage is stitched together, such as, be all the multisection type electric drive axle of powered phase for a whole section, also the stator of all powered phases can be stitched together as mandrel, and no longer needs an extra mandrel.
Above content is only embodiments of the invention, and those skilled in the art can make various amendment and not depart from scope and spirit of the present invention.
