Technical field
The present invention relates to a kind of fluid varactor machine, belong to hydropneumatic apparatus field, it belongs to a kind of and is slided to axial and realized double-function variable vane pump or the motor of variable by parts.
Background technique
At present, known oil hydraulic pump (motor) mainly contains plunger type and a few class forms such as blade type and gear type, variable displacement pump mainly contains plunger type and blade type, wherein plunger type major defect is that complex structure volume is heavy, single-acting blade-type variable displacement pump pressure imbalance, wearing and tearing are large, pressure and rotating speed are very limited.
Vane pump is a kind of dynamical element being widely used in hydraulic system.Vane pump have output flow evenly, the feature such as smooth running, noise be low, so it is widely used in the hydraulic system of lathe, boats and ships, engineering machinery etc.
The vane pump being applied at present in hydraulic system has single-acting formula and the large class of double action two.Single acting vane pump is mainly by stator, rotor, blade and thrust plate form, owing to there is certain offset in stator and rotor, so when rotor, blade, rotor, the sealed volume volume that the thrust plate of stator and both sides surrounds will change, by the suction on thrust plate, oil drain out is realized oil suction and the oil extraction of oil pump, the eccentric amount e that changes stator and rotor just can change the size of vane pump discharge capacity, but because this pump is monolateral pressure oil output, so the radial force that the main shaft of pump and bearing are subject to is larger, this has just affected the working life of this pump and the raising of pressure greatly.
Double-acting vane pump is mainly also comprised of blade, thrust plate and rotor and stator, and the stator curve of this pump is comprised of two pairs of symmetrical circular arcs and four sections of transition curves.When the main shaft rotor driven of pump rotates, blade is just along with stator curve stretches out and indentation in the blade groove of rotor, the blade that often rotates a circle stretches twice in rotor vane groove, complete twice oil suction and oil extraction, be referred to as double-acting vane pump, two oil sucting cavities and two oil-discharging cavities of this pump are arranged symmetrically with, so it is in a basic balance to act on epitrochanterian radial hydraulic pressure, the life-span of bearing is longer, be conducive to the raising of pressure, but the Theoretical flowing capacity of this pump is immutable substantially, therefore also limited to a certain extent the application of this pump.
Although above-mentioned form is through updating, performance has had very large lifting, but has very large deficiency, and this has all limited the application of this two classes pump to a certain extent.Make the equipment complex and expensive more that also becomes simultaneously.
Technology of the present invention and existing vane pump are comparatively approaching, and similar patent has: patent, double-function variable vane pump CN 2426529 Y, double-function variable vane pump CN 87206578 U, double-function variable vane pump CN 1128294 C, double-function variable vane pump CN 2109447 U etc.It is inhomogeneous that the shortcoming of patent CN 2426529 Y mainly contains 1. blade wears, 2. variable oil sealing dish pressure at both sides is uneven, 3. dependent variable oil sealing dish pressure at both sides imbalance causes variable adjusting screw rod to bear strength is excessive and make to regulate in work difficulty, 4. manually variable controlling device regulates inconvenience, 5. can not under high pressure work.
The main distinction of the present invention and prior art is; It arranges a dividing plate dish rotating with rotor and blade synchronization on rotor and blade, dividing plate dish external diameter is greater than the maximum inner diameter of stator, dividing plate dish can slide to axial with rotor, blade, dividing plate dish arranges the groove identical with blade quantity, between rotor, dividing plate dish, blade, seal, dividing plate dish is divided into former and later two parts by double-acting vane pump.Dividing plate dish can be located in the middle of the first stator, the second stator simultaneously, the negative camber of the first stator, the second stator is identical, dividing plate dish external diameter is greater than the maximum inner diameter of the first stator, the second stator, between the first stator, dividing plate dish, the second stator, seal, the first stator, the second stator and dividing plate dish and rotor and blade slide to axial, thereby the swept volume that changes former and later two some work chambeies is realized variable object.The pump housing self can not produce and close oil and cavitation, and airtight in pump well to realize seal leakage few, and blade wear is even, pressure balance, structure of the present invention is relatively simple, and high low speed and high low pressure performance are compatible stable, variable regulation range is large, convenient and easy, applied widely.
