Description
Technical field
The present invention relates to machine field, the fixing rotor structure of especially a kind of hollow type outer shaft.
Background technology
The rotor of existing all kinds of motors is generally axis and fixes, and drives external equipment by middle shaft rotation, and rotor inside mostly is solid construction.The motor of this kind of rotor structure, manufacture and mounting process are comparatively complicated, and cost is higher, and especially rotor dispersing hot property is bad, in some special enclosure space application scenarios, motor performance is promoted and cause useful life serious restriction.In addition, the working methods that adopt motor and pump combination in engineering technology application more, thus by motor driven pump work, being realized the object of gas, fluid transport, system cost is higher and take up room greatlyr, transports and installation and maintenance inconvenience etc.
Summary of the invention
The invention provides the fixing rotor structure of a kind of hollow type outer shaft, because rotor portion adopts hollow structure, effectively increased rotor area of dissipation and approach, make to adopt the motor of this structure to there is good heat dispersion.Its manufacture craft is simple, significantly reduces cost and the weight of motor, has promoted runnability and the useful life of motor.And be convenient to realize motor-and-pump integrated function, and simplify largely gas-liquid transmission system structure and equipment, saved usage space and cost.
The present invention is achieved in that
The rotor structure that hollow type outer shaft is fixing, comprises stator 1, hollow rotor 2, rotor fixedly end ring 3, rotor rigid bearing 4, air gap 5, hollow multi-channel structure 6; It is characterized in that, the inner hollow multi-channel structures 6 that adopt of hollow rotor 2, and by rotor fixedly end ring 3 through rotor rigid bearing 4, be connected with stator 1, between stator 1 and hollow rotor 2, be air gap 5.
Described hollow rotor 2, without inner axis, adopts the rotor rigid bearing 4 being connected with stator 1 as outer shaft, makes hollow rotor 2 can realize the motion that rotates in a circumferential direction.
Described stator 1 end is outstanding, forms bearing groove, covers fixedly end ring 3 of rotor completely, when hollow rotor 2 rotation, can play safety protection function.Make as far as possible evagination or do not expose not of rotating part, avoid contact personnel or other exterior objects to cause injury accident or affect motor moving.
Described hollow rotor 2 and rotor fixedly end ring 3 adopt split-type structurals, are easy for installation and removal; A plurality of bolts that dependence distributes along even circumferential connect, and after screwing, have elasticity, can regulate the compression degree to bearing, effectively reduce the caused frictional dissipation of difference because of installation dimension, avoid occurring the generation of the mechanical breakdowns such as eccentric wear.
Described rotor rigid bearing 4 is thrust bearing, squares up bilateral or oblique angle is monolateral, can adopt mechanical bearing, also can adopt magnetic suspension bearing, effectively to reduce the spin friction loss producing under High Rotation Speed, improves electric efficiency.
The hollow multi-channel structure of described rotor consists of single hole, diplopore or porous, and when passage is single hole, hole shape can be a concentric circle, can be also the fan-shaped of semicircle; When passage is porous, hole shape be fan-shaped, encircle fan-shaped, circular, also can be according to the mobile requirement of fluid, be designed to other special shapes arbitrarily.
When the hollow multi-channel structure 6 of described rotor is diplopore or porous, each hole is circumferentially symmetric with respect to rotor axis edge, and between adjacent holes, has the bridge shape interval of certain width, and the width at this bridge shape interval generally requires design according to structural strength.
When air duct is dispelled the heat in hollow multi-channel structure 6 conducts of described rotor, its wall can not process, and air turbulence can be strengthened in the surface of inner wall coarse, improves radiating effect; During as gas or liquid supplying passage, need do smooth treatment to reduce resistance.According to the difference of pumped (conveying) medium, need to stick or melt note other materials, do insulate, the processing such as anticorrosion, waterproof and dustproof or antiscale.
Compared with prior art, tool of the present invention has the following advantages:
Adopt the motor manufacture craft of this rotor structure simple, for convenience detach and installation; Weight is lighter, both cost-saving, again convenient transportation and installation.Hollow multi-channel structure can be used as the passage of gas or liquid, and perfect heat-dissipating is conducive to improve the performance and used life of motor, is specially adapted to, in some work condition environments that temperature rise is had relatively high expectations, be convenient to realize motor-and-pump integrated equipment simultaneously.

Embodiment
Below in conjunction with Fig. 1-Fig. 5, the present invention is further illustrated:
As shown in Figure 1, the fixing rotor structure of this hollow type outer shaft comprises stator 1, hollow rotor 2, rotor fixedly end ring 3, rotor rigid bearing 4, air gap 5, hollow multi-channel structure 6.Wherein, the punching of rotor employing silicon steel sheet folds and forms.
Hollow rotor is connected with stator through rigid bearing by fixing end ring, and wherein stator end is partly outstanding, forms groove, and fixing rotatablely moving of end ring played a protective role.Fixedly end ring and rotor adopt split-type structural, convenient installation; A plurality of bolts that dependence distributes along even circumferential connect, and bolt can overlap elastomeric pad or spring, after making to screw, has elasticity, can regulate the compression degree to bearing, bearing adopts mechanical thrust bearing, while flowing through gas or liquid in hollow multi-channel structure, plays the effect of offsetting axial force.
In hollow multi-channel structure, number of channels can be one, also can be a plurality of, and with respect to electrical axis along circumferentially symmetrical, according to different quantity, can form different channel designs and hole shape.As shown in Figure 3, number of channels is two, is two and half scallop holes after symmetrical, and bridge shape interval forms " one " font.As shown in Figure 4, number of channels is three, is three ring scallop holes after symmetrical, and bridge shape interval forms " people " font, and the rest may be inferred can form loose structure.The hole shape of passage also can adopt circular hole, and as shown in Figure 5, number of channels is four circular holes, symmetrical along circumference.
When motor moves, can connect outside pump by rotor, hollow multi-channel structure can be used as gas, fluid passage; Or impeller is installed on conduit wall, and the centrifugal force that utilizes rotor high-speed rotation to produce is realized motor-and-pump integrated function.Because employing hollow structure, and have by gas, liquid functional, so adopt the motor of this structure to there is good heat sinking function.
Hollow multi-channel structure is as heat radiation during air duct, and its wall can not process, i.e. the direct ingress of air of inner surface after silicon steel plate packing, and air turbulence can be strengthened in the surface of inner wall coarse, improves radiating effect; During as gas or liquid supplying passage, need do smooth treatment to reduce resistance, will guarantee good heat conductivility simultaneously, as adopted stainless steel.According to the difference of pumped (conveying) medium, also need to stick or melt note other materials, do insulate, the processing such as anticorrosion, waterproof and dustproof or antiscale, as adopted the materials such as polytetrafluoroethylene, can guarantee to prolong that journey resistance is little, insulation, anticorrosion, waterproof, antiscale, heatproof etc.
The foregoing is only better embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
