Description
Technical field
The present invention relates to the blade support structure of compressor, particularly about the installation position of leaf spring, make the spacing minimizing of electric structure portion and compression structure part and dwindle the blade support structure of the compressor of shaft length and the hot engagement height of rotor by the change support blade.
Background technique
In general, vane compressor is crimped on blade on the solid of rotation cylinder interior spatial division is sucked, compresses, discharges refrigerant gas for suction and compressing area.
Fig. 1 is the bottom sectional arrangement drawing of vane compressor in the past, and Fig. 2 is the oblique drawing of the compression structure part of compressor, and Fig. 3 is the sectional arrangement drawing of the compression structure part of compressor, and Fig. 4 is the planimetric map of the blade support structure of compressor.
As shown in the figure, vane compressor in the past is by the electric structure portion that is installed in casing 1 inside upper part; Be connected electric structure portion, the compression structure part that can suck, compress, discharge refrigerant gas constitutes.
Electric structure portion is installed in the inside of casing 1, by the stator 11 with winding coil; Be pressed into fixed rotating shaft 4 at core, and can be inserted in rotor 12 formations of stator 11 inner rotation.
Compression structure part is for suction, compression refrigeration gas have inner space V, comprises the cylinder 2 of the Lower Half that is fixed on casing 1; Conclude separately on cylinder 2 and below, form the upper axis board 3A and the lower shaft board 3B of cylinder together; When combining with the rotor 12 of electric structure portion, with shaft bearing plate 3A separately, 3B connects combination, and the power of electric structure portion is conveyed to the rotating shaft 4 of compression structure part; Combine with rotating shaft 4 or one-body molded and possess the division plate 5 that forms with sinusoidal wave apperance of bend point separately in bi-side up and down for the inner space V of cylinder 2 being divided into the 1st pressing chamber S1 and the 2nd pressing chamber S2; Contact its lower end and upper end separately dividing plate 5 two sides, and when rotating shaft 4 is rotated separately pressing chamber S1, S2 is divided into the 1st blade 6A and the 2nd blade 6B of suction zone and constricted zone; Two ends are each blade 6A of resilient support simultaneously, the leaf spring 7 of 6B; Be installed in the external profile surface of upper axis board 3A and lower shaft board 3B, decay produces the top baffler (not shown) and the bottom baffler (not shown) of discharging noise from each pressing chamber S1 when S2 discharges pressurized gas.
Rotating shaft 4 is inserted in metal (upper plate 3A, the axis hole of 3B and supported axial region 4a with radial direction by the 3b of radial bearing portion; Form by metal (upper plate 3A with the radial direction expansion in the Lower Half of axial region 4a, the enlarged portion 4b that the propelling bearing 3a of portion of 3B supports and its outer circumferential face one or after be assembled and divide plate 5.
Enlarged portion 4b makes its center consistent with the center of axial region 4a and when plane projection, is formed in axial region 4a same in the heart.When enlarged portion 4b is the center to divide plate 5, form the identical symmetric figure of both sides diameter up and down again.
Undeclared symbol r1 is the radial bearing radius surface in the drawing, and r2 is a cardan shaft bearing surface radius, and SP is a suction pipe.
The working procedure of vane compressor in the past is as follows:
When the winding coil power supply of the stator 11 of giving electric structure portion and rotor 12 when rotating, rotating shaft 4 and division plate 5 with rotor 12 combinations rotate to a certain direction, the blade 6A that contacts with the bi-side up and down of dividing plate 5 separately, 6B is with the height of dividing plate 5, back and forth change the 1st pressing chamber S1 of cylinder 2 and the volume of the 2nd pressing chamber S2 with opposite mutually up and down direction, meanwhile, by being installed in the suction pipe SP of above-mentioned cylinder 2 one sides, new refrigerant gas is drawn into the 1st pressing chamber S1 and the 2nd pressing chamber S2 continuously, after refrigerant gas is compressed gradually with the rotation of dividing plate 5, when the both sides protrusion curved face part of dividing plate 5 is discharged the moment of the moment of starting point to each exhaust port of process (not shown) from arrival, by alternately discharge of exhaust port separately.
At this moment, the corresponding metal (upper plate of the axial region 4a of rotating shaft 4 3A, the axis hole of 3B is (promptly, when the r1 radial bearing surface) being supported with radial direction, the corresponding metal (upper plate of enlarged portion 4b 3A, the plane of 3B (that is r2 cardan shaft bearing surface) kept stable rotation with the rotor shaft direction support.
But, as above the compressor of structure formation moves up and down with rotating shaft 4 for supporting in the past, and the division plate 5 of compression refrigeration gas and the blade 6A that is in contact with it, 6B and make it not break away from the mounting point, simultaneously for preventing that leaf spring 7 interferes (as shown in Figure 1) with stator in the compressor operating, make and extend to top and the bottom shaft bearing plate 3A, the supporting portion 7a of the outer circumferential face of 3B keeps a determining deviation L1 with vertically being connected the supporting portion and having leaf spring 7 and the stator 11 that the joint 7b of certain-length constitutes, thereby, heat is engaged in the rotor 12 of rotating shaft 4 and the spacing between the enlarged portion 4b, that is, hot engagement height L2 also should keep more than the determining deviation.When hot engagement height L2 is too high, prolong with the length of rotating shaft 4, axle rigidity dies down, thereby, mechanical, electrical vibration and noise problem when rotating.
Summary of the invention
What propose in order to address the above problem the objective of the invention is, and mounting structure and orientation by the leaf spring that improves support blade are provided, and the hot engagement height that reduces rotor reduces the blade support structure of the compressor of mechanical, electrical vibration that causes and noise.
In order to reach order as above of the present invention ground, blade support structure of the present invention includes: the leaf spring patchhole that connects compresser cylinder and top and the bottom shaft bearing plate thereof; Be inserted in above-mentioned leaf spring patchhole, the leaf spring of two ends elastic support blade end, it is characterized in that: above-mentioned leaf spring patchhole is to arrange the supporting portion that leaf spring is installed with the perpendicular direction of the radius of rotating shaft, and, the leaf spring patchhole with the perpendicular elongation line of radial direction on connect and form.
Above-mentioned leaf spring patchhole connects top and the bottom shaft bearing plate and cylinder and extends to its outer circumferential face, forms with the rectangular through slot.
Above-mentioned leaf spring is by supporting blade end separately and extending to above-mentioned leaf spring patchhole and the supporting portion that forms; With for being connected above-mentioned supporting portion with the Vertical direction complications, and the joint that is inserted in the leaf spring patchhole constitutes.
Advantage and good effect: according to aforesaid blade support structure according to compressor of the present invention, the mounting point of leaf spring is moved and can not interfered with the terminal part of stator to the central direction of rotating shaft, thereby, the mounting point of leaf spring can be enhanced a determining deviation L3, and be engaged in the rotor of rotating shaft and the spacing between the enlarged portion with the L4 maintaining heat, (instant heating engagement height) and the blade support structure comparison of compressor in the past, along with dwindling of hot engagement height, machine, electric oscillation and noise also are reduced thereupon, simultaneously, also has the effect that can improve compressor reliability.
