Abstract
The invention discloses a cylinder for a rotary type compressor. A flexible hinge mechanism capable of generating elastic deformation is arranged on the end face of the high-pressure cavity side of the cylinder and is used for reducing the force acting on a crankshaft. According to the cylinder for the rotary type compressor, the phenomenon of eccentric wear of an eccentric circle of the crankshaft can be effectively reduced, the performance of the rotary compressor is improved, and the service life is prolonged. The invention also provides the rotary type compressor.
Description
Technical field
The present invention relates to a kind of cylinder for rotary compressor and comprise the rotary compressor of this cylinder.
Background technique
When rotary compressor work, by bent axle rotor driven High Rotation Speed, air-breathing from outside, and the gas compression sucking is become to pressurized gas, then discharge.In this process, the cylinder inner wall of hyperbaric chamber side bears the High Pressure of pressurized gas always, this active force cannot cushion, finally bent axle is produced to great reaction force, easily cause bent axle to tilt, cause winding degree in the time that crankshaft high-speed turns round to increase, produce eccentric wear, and then causing compressor efficiency low, working life is short.
Summary of the invention
Easily cause that for the cylinder in above-mentioned existing rotary compressor bent axle tilts, further causes the problem of Crankshaft, the invention provides a kind of cylinder for rotary compressor and rotary compressor thereof, it can reduce the eccentric wear of bent axle.
For a cylinder for rotary compressor, wherein, on the end face of the hyperbaric chamber side of described cylinder, be provided with the flexure hinge mechanism that can produce resiliently deformable, for reducing the suffered active force of bent axle.
In an embodiment, described flexure hinge mechanism comprises the flexible slot circumferentially arranging on the described end face of described cylinder therein.
In an embodiment, described flexible slot width is 0.5mm to 1mm therein.
Therein in an embodiment, the described flexible slot degree of depth is described cylinder length 1/3 to 1/2.
The present invention further provides a kind of rotary compressor that comprises above-mentioned any cylinder.
A kind of cylinder for rotary compressor of the present invention and rotary compressor, its end face in the hyperbaric chamber side of cylinder has been set up flexure hinge mechanism, this flexure hinge mechanism can resiliently deformable, the active force of mitigation on the inwall of the hyperbaric chamber side of cylinder, thus the suffered active force of bent axle further alleviated.Due to the suffered reaction force attenuation of bent axle, be therefore not easy run-off the straight, effectively reduce the eccentric wear of crankshaft eccentric circle, extend the working life of compressor.
Brief description of the drawings
Fig. 1 a, 1b, 1c are schematic diagram of the present invention.
Fig. 2 is the structural representation of cylinder of the present invention.
Fig. 3 is the enlarged view of A portion in Fig. 2.
Embodiment
By reference to the accompanying drawings the present invention is carried out to exemplary description, wherein identical parts represent with identical label.
The schematic diagram that Fig. 1 a, 1b, 1c are cylinder of the present invention.Lateral Force is in vertical plane (being equivalent to cylinder inner wall), as Fig. 1 a, after suffered active force increases, plane generation resiliently deformable, suffered transverse force is broken down into the power of parallel-slope and the power perpendicular to inclined-plane, as Fig. 1 b, alleviate the effect of the suffered transverse force of plane, after reaction force attenuation, the plane of distortion reverts to vertical plane again, as Fig. 1 c.
According to above-mentioned principle, Figure 2 shows that cylinder 10 of the present invention, wherein at the end face of the hyperbaric chamber side of cylinder, one flexure hinge mechanism is circumferentially set.Preferably, this flexure hinge mechanism comprises flexible slot 11.When work, crankshaft high-speed running, drives rolling rotor High Rotation Speed, when the pressure of hyperbaric chamber raises, flexible slot 11 develops into revolute pair, and the cylinder wall of flexible slot both sides (near the part of cylinder inner wall and the part in close cylinder outside) can relatively rotate.And before high pressure action,, before the pressure of hyperbaric chamber raises, flexible slot maintains the original state, and does not move, as shown in Figure 1a.In the time that high pressure moves, when the pressure in hyperbaric chamber raises, the cylinder wall of flexible slot both sides relatively rotates, and pressure-acting, on flexible slot, is decomposed into the power of vertical bevel direction and the power of parallel bevel direction by inclined-plane, as shown in Figure 1 b; After high pressure release,, after the pressure decreased of hyperbaric chamber, flexible slot restores to the original state, as Fig. 1 c; So iterative cycles.Due in the time that hyperbaric chamber moves, flexible slot rotates and produces resiliently deformable, and transverse force is decomposed, thereby effectively alleviate the reaction force of rolling rotor to crankshaft eccentric circle, reduce the eccentric wear phenomenon of crankshaft eccentric circle, improve compressor performance, increase the working life of compressor.
With reference to figure 3, this flexible slot 11 preferably circumferentially arranges at the end face of the hyperbaric chamber side of cylinder.For further guaranteeing intensity and the cylinder end face seal of cylinder, preferably, the width of this flexible slot is 0.5mm to 1mm.Preferably, the degree of depth of this flexible slot is cylinder length 1/3 to 1/2.
The present invention also provides a kind of rotary compressor that comprises above-mentioned cylinder.Rotary compressor of the present invention, due to flexure hinge mechanism being set in cylinder, reduces the eccentric wear phenomenon of crankshaft eccentric circle, has improved this compressor performance, and has extended working life.
The above embodiment has only expressed the preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
