Description
Technical field
The present invention relates to rotary slide sheet type fluid machinery technology, particularly a kind of variable sliding-vane central rotation compressor is applicable to compressor, motor and the internal-combustion engine of sliding vane.
Background technique
Rotary slide sheet type compressor or sliding vane fluid machinery have: simple in structure, component are few, motional inertia is less, running is steady, efficient is than advantages such as height, be widely used on the fluid machineries such as various compressors, motor.
But also there are some shortcomings in rotary slide sheet type compressor, has limited its development, such as: mechanical wear is serious, energy loss is big, low-speed performance is bad etc., makes to leak and increases the weight of, and the life-span reduces.Cause the key factor of above defective to be: the slide plate radial seal relies on the structural feature of line contact sealing.And causing the reason of this line contact sealing to be: rotor is to be installed in prejudicially in the cylinder, rotor cylindrical and cylinder surfaces are tangent on how much, no matter how the angle of vane slot changes, the spin axis of slide plate and cylinder-bore axis are inconsistent all the time, make the slide plate radial surface can only be processed into the less arc surface of radius, thereby causing line contacting structure between slide plate and the inner surface of cylinder block, its effect must be inferior to the reciprocal compressor that cylinder body is face contact seal.
Summary of the invention
In order to overcome the prior art above shortcomings, the invention provides a kind of variable sliding-vane central rotation compressor, to improve the sealability of compressor, reduce mechanical wear, cut down the consumption of energy.
Variable sliding-vane central rotation compressor of the present invention, comprise the compressor case that cylinder block and both sides cylinder end piece constitute, suction port and air outlet are arranged on the cylinder block, the rotor that is positioned at cylinder block is installed on the cylinder end piece by axle, some slide plate notches are arranged on the rotor, in the slide plate notch slide plate is set; All have an annular groove on the concave surface of described two cylinder end piece inboards, the opposing side of described epitrochanterian slide plate notch external port is the cylndrical surface, slide plate notch proximal ends is a cavity, slide plate is installed in the slide plate notch, bow type slide block is set respectively between the corresponding cylndrical surface of bi-side, slide plate outer end and slide plate notch external port, both sides, slide plate the inner are U-shaped slide block of holding respectively, also is slidingly matched with it in two sliding axles insertions in each U-shaped slide block outside and the annular groove of its adjacent cylinder end cap inboard.
This variable sliding-vane central rotation compressor is novel, during the rotor rotation, the slide plate that radially slides drives slide block and rotates together, because the slide block of the slide plate the inner also annular groove on the cylinder end piece slides, the axis that causes the spin axis of slide plate to depart from rotor is converted to the cylinder block axis, slide plate is around the swing of the axis of the cylndrical surface of slide plate notch external port like this, guarantees the radially face contact seal of cambered surface and cylinder block internal surface of slide plate all the time.Face contact seal improves the sealability of compressor greatly, and energy consumption reduces, and mechanical wear reduces, and increase working life.Also can install seal ring additional as reciprocal compressor on blade, effect will be desirable more.

Embodiment
The present invention is further described below in conjunction with embodiment's accompanying drawing.
Fig. 1 a, b are the structural representation figure of 1 one groups of slide plate lists of embodiment active chamber compressor.This compressor comprises that cylinder block 14 and both sides cylinder end piece 12 constitute compressor case, suction port 27, air outlet 28 are arranged on the cylinder block 14, all have an annular groove 11 on the concave surface 21 of two cylinder end piece 12 inboards, annular groove 11 is coaxial lines 2 with cylinder block 14 inner cylinder.Rotor 19 is installed on the cylinder end piece 12 prejudicially by axle 1, it between rotor 19 and the shell active chamber 13, slide plate notch 20 is arranged on the rotor 19, the opposing side of slide plate notch 20 external port on the rotor 19 is the cylndrical surface, the cylndrical surface axis is 8, slide plate notch 20 proximal ends are a cavity 10, and the cavity 10 of slide plate notch 20 proximal ends is wideer than slide plate notch 20 external port.
Wherein, described U-shaped slide block 3 comprises two guide plates 6 and connection strap, and two guide plates 6 are installed in the two ends of connection strap one side respectively, and fixing described two sliding axles, 4, two guide plates, 6 inner side surfaces of connection strap opposite side and slide plate 5 are slidingly matched.Slide plate 5 outer end radial surfaces are processed into and cylinder block 14 cambered surface that the internal surface axle center is consistent and shape is suitable, and there is seal groove 7 two cylinder end pieces, 12 inboards, and seal ring 9 is installed in the seal groove 7, to increase sealing effect.
Wherein 1 group of slide plate working principle with reference to Fig. 1,2 explanation embodiments 1.Rotor 19, slide plate 5 etc. are around the rotational of axle 1; The axis of cylinder block 14, end cap 12 and chute 11 is 2.Slide plate 5 is close to cylinder block 14 and is slided under action of centrifugal force, and slide plate 5 front and back active chambers 13 volumes change, and realize compression and air-breathing function, make compressor operating.In conjunction with Fig. 1,2a, slide block 3 and sliding axle 4 is because the effect of guide plate 6 can only slide up and down along slide plate 5, and therefore, the vertical line of line 22 mid points overlaps with the center line 23 of slide plate 5 between the every pair of sliding axle 4.
During rotor 19 rotation, slide plate 5 drives slide blocks 3 and rotates together, because a pair of sliding axle 4 of slide block 3 inserts slip among the chutes 11, causes the inner of slide plate 5 to depart from the axis of rotor 19 under the effect of slide block 3.Because of rotor 19 different with the axis of chute 11, the inner that causes slide plate 5 is that swing in the axle center with 8 in cavity 10, the principle of passing this circular arc center of circle according to the perpendicular bisector of any 2 lines on the circular arc, this vertical line 23 to sliding axle 4 line mid points (also being the center line of slide plate 5) must be through the axis 2 (also being the axis 2 of cylinder block 14) of chute 11, and this center line 23 forwards in the process of 90 degree positions and all passes axis 2.
So, though rotor 19 is the axis rotations around axle 1, and the slide plate 5 above it rotates around cylinder block axis 2, the radial surface of slide plate 5 is processed into and cylinder block 14 cambered surface that the internal surface axle center is consistent and shape is suitable, just can make slide plate 5 and cylinder block 14 inwalls keep face contact seal, significantly reduce wearing and tearing, cut down the consumption of energy and reduce to leak.Fig. 2 b, c are that the corner of embodiment's 1 slide plate 5 is spent positions at 90 degree, 270 respectively, can illustrate that slide plate is always around axis 2 rotations.
