Embodiment
Below, describe the preferred embodiments of the present invention in detail with reference to Fig. 3 to Fig. 5, so that the general technical staff of the technical field of the invention implements easily.
Rotary compressor 1 according to present embodiment comprises: the housing 10 that forms outward appearance; Form the cylinder portion 20 of pressing chamber 22 in the inside of housing 10; Be arranged at electronic 30 of inside upper part of housing 10; Be arranged at the press part 40 of the lower inside of housing 10, this press part 40 compresses compressed medium in the rotation of the inside of pressing chamber 22 and from electronic 30 reception rotating force.
Cylinder portion 20 comprises: the cylinder 21 that forms pressing chamber 22; The flange part 25 that is used for the upper and lower opening of closed cylinder 21.
Cylinder 21 is and has the cylindric of upper and lower opening, to form pressing chamber 22.Present embodiment is small-sized capacity than existing rotary compressor.That is, in 1～5cc scope, Given this height of cylinder 21 is preferably greatly in 5～15mm scope greatly for the compression volume of cylinder 21.
Flange part 25 comprises the top that is installed on cylinder 21 respectively and the upper flange 25a and the lower flange 25b of bottom, supports the rotating shaft 41 of press part 40 in the time of with the last side opening that is used for closed compression chamber 22 and open lower side.
Comprise for electronic 30: the columnar stator 31 that is fixed in the inner face of housing 10; Rotatably be arranged at the inside of stator 31 and the rotor 33 of the rotating shaft 41 that central part is incorporated into press part 40.When connecting power supply, electronic 30 rotor 33 rotations, thus make rotating shaft 41 rotations and drive compression portion 40.
Press part 40 comprises: from electronic 30 rotating shaft 41 that receives rotating force; What protrude from rotating shaft 41 along radial disbalance in the inside of pressing chamber 22 rolls ring portion 43, according to the rotation of rotating shaft 41 compressed medium of pressing chamber 22 is compressed being used for.
Rotating shaft 41 is arranged as the center that connects pressing chamber 22.Rotating shaft 41 receives rotating forces and rotates from electronic 30 rotor 33.
Roll ring portion 43 according to the rotation of rotating shaft 41 and eccentric rotation is compressed the compressed medium of pressing chamber 22 inside with this.Rolling ring portion 43 forms as one with rotating shaft 41.Than rotary compressor in the past, be the lower small-sized rotary compressor of height of pressing chamber 22 according to the rotary compressor 1 of present embodiment, so the length of rotating shaft 41 is shorter than structure in the past.In view of the above, even if rotating shaft 41 is tilted, flange part 25 can not stick up yet, thereby can not form the slit at pressing chamber 22.Simultaneously, form as one with rotating shaft 41, also can keep the airtight confidence level of pressing chamber 22 even if will roll ring portion 43.
Press part 40 is made of the strong material of wear resistance.That is, the material of press part 40 can comprise have nickel (Ni), the cast iron of chromium (Cr), molybdenum (Mo).Since roll ring portion 43 for and will blade described later (vane, not shown) continue the parts of contact, therefore should constitute with the strong material of wear resistance.Than rotary compressor in the past, the rotary compressor 1 of present embodiment is the lower small-sized rotary compressor of height of pressing chamber 22, so the length of rotating shaft 41 is shorter than structure in the past.In view of the above, even if rotating shaft 41 is adopted than the more expensive wear-resisting material of expense in the past, its manufacturing expense also can significantly not rise, and is integrated into rotating shaft 41 owing to will roll ring portion 43 on the contrary, therefore can reduce manufacturing process and reduces whole manufacturing expense.
In addition, press part 40 can be by the material as the rotating shaft 141 of in the past rotary compressor 100, for example formation such as gray cast iron, spheroidal graphite cast iron.At this moment, shown in Fig. 4 b, roll ring portion 43 and preferably comprise coating layer 43a by the wear-resisting material hard-coating.At this, hard-coating can apply or a kind of in applying of Tungsten carbite carbon film (WC/C:tungsten carbide/carbon) for diamond-like-carbon (DLC:Diamond Like Carbon).
Be formed with thrust face 45 on the upper and lower plates face that rolls ring portion 43 according to the rotary compressor 1 of present embodiment.That is, for existing rotary compressor 100, need to form thrust face 143a rolling on the upper and lower plates face of ring portion 143, on the upper and lower plates face of the eccentric part 142 that is independent of the rotating shaft 141 of rolling ring portion 143, also need to form simultaneously thrust face 142a.But, in the present embodiment,, therefore can form thrust face 45, thereby reduce manufacturing process by a technology owing to roll ring portion 143 and rotating shaft 141 forms as one.Thrust face 45 forms by grinding (grinding work).
In addition, the ring portion 43 of rolling according to the rotary compressor 1 of present embodiment is formed with quality and reduces groove 47.Quality reduces groove 47, and to be used to reduce with rotating shaft 41 be quality poor between the mutual opposed zone of rolling ring portion 43, center.Can prevent in view of the above with the rotating shaft 41 of rolling ring portion 43 buckling phenomenon of contingent rotating shaft 41 that is the center owing to roll the difference of quality of ring portion 43.At this, the size that quality reduces groove 47 is that the mutual opposed quality of rolling ring portion 43 in center becomes identical size and position with optimum seeking site for making with rotating shaft 41.
In addition, reduce groove (not shown) though also can form quality on existing rotary compressor 100, because eccentric part 142 and roll ring portion 143 and be respectively independently parts, so the size that quality reduces groove can be restricted.But, in the present embodiment and since rotating shaft 41 with roll ring portion 43 and form as one, therefore can form relatively large quality and reduce groove 47 than in the past structure.
In the present embodiment, quality reduces groove 47 along axially the forming with the form of through hole of rotating shaft 41, but axial depression that also can be and forming from the upper board face that rolls ring portion 43 or lower panel face along rotating shaft 41.In addition, quality minimizing groove 47 forms one in the present embodiment, but also can form more than two.
In addition, press part 40 also comprise according to the rotation of rolling ring portion 43 along pressing chamber 22 radially advance and retreat move the time zoning pressing chamber 22 blade (vane).This blade is contacted with the outer surface that rolls ring portion 43, is constricted zone and non-constricted zone with this with pressing chamber 22 zonings.
Cylinder 21 is formed with blade groove (vane slot, not shown), to be used to accommodate the turnover of blade and guide blades.
More than, be used for explanation and illustrated rotary compressor 1 in the present embodiment and have a pressing chamber 22, but state that at this present invention is also applicable to having two rotary compressors with upper compression chamber.
Though, more than the diagram and embodiments of the invention have been described, it will be appreciated by those skilled in the art that under the prerequisite that does not break away from principle of the present invention or guiding theory, can carry out various distortion to embodiments of the invention.Protection scope of the present invention should be determined by claims and equivalent thereof.
