Abstract
The invention discloses a rolling rotor type compressor which comprises a shell, a cylinder, a crank shaft, a stator, a rotor, a stator fixing device and a rotor fixing device, wherein the stator is fixed to the shell through the stator fixing device, the rotor is located outside the stator and fixedly connected with the crankshaft through the rotor fixing device, and therefore the rotor rotates around the stator on the outer side of the stator and drives the crank shaft to rotate. By adopting the rolling rotor type compressor, consumption of coil windings and other relatively expensive materials is greatly reduced, and therefore cost is lowered; in addition, due to the fact that the stator and the shell do not make direct contact, noise pollution is greatly reduced.

Accompanying drawing explanation
Fig. 1 is the structural representation of the rolling rotor compressor of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, presently preferred embodiments of the present invention is described in detail, in order to become apparent from understanding the purpose of the present invention, feature and advantage. It should be understood that embodiment shown in the drawings is not limitation of the scope of the invention, and simply to illustrate that the connotation of technical solution of the present invention.
The present inventor is being furtherd investigate on the basis of great many of experiments, it is surprised to find that the rotor breaking through prior art is positioned at the compressor of stator interior, the outside that rotor is arranged in stator can be substantially reduced the overall manufacturing cost of compressor, can effectively reduce motor noise in the course of the work simultaneously. By within the compressor by rotor the mode being arranged at outside stator to solve Compressor Manufacturing cost high, noise such as is difficult to alleviate at the difficult problem that always annoying those skilled in the art, has unexpected technique effect.
As it is shown in figure 1, the compressor 100 of one embodiment of the invention includes housing 101, reservoir 102, cylinder 103, bent axle 104, stator 105, rotor 106, stator support 107 and rotor field spider 108. In order to more clearly describe the present invention, the present embodiment and diagram are to illustrate with the rolling rotor compressor of vertical structure for concrete example, but, it is in the rolling rotor compressor that the present invention can also be applied to such as horizontal other structures such as grade that those skilled in the art should know what know, and is not limited to the concrete structure shown in Fig. 1.
As it is shown in figure 1, in the present embodiment, reservoir 102 is positioned at outside housing 101, and cylinder 103, bent axle 104, stator 105, rotor 106 and stator support 107 and rotor field spider 108 are all positioned at housing 101. Cylinder 103 is positioned at housing 101 bottom, and stator support 107 is positioned at above stator 105, and rotor field spider 108 is positioned at below rotor 106, and it is internal that bent axle 104 is positioned at stator 105, and rotor 106 is positioned at outside stator 105.
As it is shown in figure 1, in the present embodiment, rotor 106 is cylindrical, and the external diameter of rotor 106 is less than the internal diameter of housing 101, and therefore, rotor 106 and housing 101 are not in contact with (internal diameter that more preferably, the external diameter of rotor 106 is far smaller than housing 101). Secondly, the external diameter of stator 105 is positioned at rotor 106 less than internal diameter and the stator 105 of rotor 106, and therefore, stator 105 does not also contact with housing 101.
As it is shown in figure 1, in the present embodiment, stator support 107 and stator 105 are bolted. Having two screws at stator 105 center, correspondingly, stator support 107 is provided with two screws, by being loaded by bolt in the screw of stator 105 and stator support 107 thus being connected fixing with stator support 107 for stator 105. And stator support 107 is connected on the inwall of housing 101 by the mode welded.It will be appreciated, however, by one skilled in the art that stator support 107 can also be connected on the inwall of housing 101 by another way, include but not limited to threaded or pin connection etc. In like manner, stator 105 can also be connected with stator support 107 in other way, including and be not limited to pin and connect or welding etc.
As it is shown in figure 1, in the present embodiment, rotor 106 is connected also by bolt with rotor field spider 108. Rotor 108 has the through hole running through whole rotor, correspondingly, rotor field spider 108 has connecting hole, by bolt being loaded in through hole and connecting hole thus being connected fixing with rotor field spider 108 for rotor 106. Rotor field spider 108 is fixing with bent axle 104 to be connected. Specifically, rotor field spider 108 has bent axle connecting hole, correspondingly, bent axle 104 is provided with screwed hole, by screw being loaded in bent axle connecting hole and screwed hole thus being connected fixing with rotor 106 for rotor field spider 108.
In another embodiment, rotor field spider 108 extends upward integral part of guide part, correspondingly, stator support 107 has circular gathering sill, this circle gathering sill is flexibly connected with the guide part on rotor field spider 108, thus when rotor field spider 108 rotates, the guide part of rotor field spider 108 slides in the gathering sill of stator support 107. By this form, rotor field spider is connected with stator support, thus improving rotor field spider stability in rotary course.
Operationally, motor switches on power, rotor 106 produces exciting current, stator 105 surrounding forms rotating excitation field, and this rotating excitation field drives rotor 106 to rotate, and the rotor field spider 108 that rotarily drives of rotor 106 rotates, it is connected owing to rotor field spider 108 is fixing with bent axle 104, therefore, the rotation rotating driving bent axle 104 further of rotor field spider 108, thus completing the compression to cold-producing medium in the cylinder.
It is more preferably, the external diameter of rotor 106 is far smaller than the external diameter of housing 101, and stator 105 is positioned at inside rotor 106, and rotor 106 does not directly contact with housing 101 with stator 105, thus the noise that motor produces is easily detected by housing 101 and sends out, efficiently solve noise pollution problem.
Additionally, due to rotor 106 is positioned at the outside of stator 105, the stator common with prior art is positioned at outside rotor and stator is compared with the compressor of housing interference fit, adopts the compressor cost of the present invention to significantly reduce. When power is identical, in an equal amount of housing, the material needed for stator significantly reduces, as it is shown in figure 1, owing to stator 105 is positioned at the inner side of rotor 106, therefore, stator diameter reduced about 1/2nd more originally, its required material also nearly reduces half.
In the present embodiment, what stator fixing apparatus and rotor fixing device were respectively adopted is stator support 107 and the form of rotor field spider 108, but, it will be understood to those skilled in the art that and much can realize otherwise being fixed in housing 101 by stator 105 and rotor 106 and bent axle 104 being fixed. The device existed in a lot of prior aries all can realize this function. As space is limited, do not enumerating herein.
Additionally, the fixed form of stator support 107 and rotor field spider 108 and stator 105 and rotor 106 can also have multiple, include but not limited to that pin is fixed, keying is fixed. The form being screwed cited by the present embodiment is only a kind of mode therein.
Above-mentioned in conjunction with accompanying drawing, embodiments of the present invention are explained in detail, but the present invention is not limited to above-mentioned embodiment. Even if should be understood that and the present invention being made various change, as long as be arranged in outside stator by rotor and rotate outside stator around stator thus reducing compressor and passing to the problem of the motor noise outside housing and both fall among protection scope of the present invention.
