Description

The serial closed cavity volume circulation increase and decrease device that crank type blade separates
Technical field
The present invention relates to the serial closed cavity volume circulation increase and decrease device that a kind of blade separates, particularly a kind of crank type The serial closed cavity volume circulation increase and decrease device that blade separates.
Background technology
At present, the blade of vane pump or motor is when rotating with rotor coaxial, and the outward flange of blade must be with cartridge type stator Medial wall be in close contact as far as possible, on medial wall, overall process is slided, this slip, makes blade outward flange and stator inner wall produce Raw abrasion;Meanwhile, blade two ends are in close contact with the two end cap inwall of pump respectively, the blade of vane pump or motor with rotor with When axle rotates, blade two ends are omnidistance on the end cap inwall of pump or motor slides, and the two ends of blade and end cap inwall produce abrasion. Above-mentioned two classes abrasions, reduce pump or the volume space bad sealing of the service life of motor, pump or motor, the output pressure of pump or The output moment of torsion of motor is difficult to improve, and unstable properties.
Summary of the invention
The present invention be directed to deficiency present in above-mentioned technology, it is provided that the serial closed cavity that a kind of crank type blade separates Volume circulation increase and decrease device;Can be used as the core component of pump or hydraulic motor;When making pump, it is turning of a kind of former vane pump Son changes mover into, and the most former rotor does not rotates, and is driven the vane pump doing the periodically movement of two coordinates by built-in bent axle;Do liquid During pressure motor, being that the rotor of a kind of former vane motor changes mover into, the most former rotor does not rotates, and drives at highly pressurised liquid The periodicity doing two coordinates under Dong moves, and then the crank rotation that driving mover is built-in, to form new vane motor; The sealing of the volume space of this pump or hydraulic motor can bring up to the level of piston type hydraulic pumps or motor, the output liquid of pump Pressure or the output torque ratio traditional blades pump of hydraulic motor or hydraulic motor improve more than 10 times, service life significantly carries High.
The object of the present invention is achieved like this: includes the stator of device, mover, telescopic blade, blade and stator Articulated mounting, blade that medial wall connects are connected also radial expansion the device hinged with mover, stator and mover two with mover End cap, total end cap of device, the input of medium and output-controlling device, bent axle and the supporting bearing of end and sealing device, dress The housing put, securing member, moment of torsion input/output terminal.
It is characterized in that: stator is a cylinder, it is integrated with device case, and mover is the cylinder being enclosed within stator Body, is respectively mounted stator and the left end cap of mover and right end cap, stator and mover two cylinder at two ends, stator axial line left and right Axis parallel, but the most coaxial;The bent axle part of bent axle is enclosed within mover cylinder, distinguishes respectively therebetween along about axial line If a bearing, the axial line of the bent axle part of bent axle overlaps with the axial line of mover cylinder, the axle center of the main shaft portion of bent axle Line overlaps with the axial line of stator cylinder body;One medium input control valve of laminating outside stator left end cap, outside stator right end cap One medium output control valve of side laminating, medium input is rigidly connected with the main shaft portion of output two control valves with bent axle;Device Two ends, housing left and right be respectively mounted left and right two total end caps of device case, the main shaft portion of bent axle and self-contained bearing and close Seal apparatus, relies on left and right two total end caps of the housing of device to install, left total end cap of the housing of device sets the most defeated of medium Entrance, right total end cap of the housing of device sets total delivery outlet of medium;The core of this device is the left and right two end cap of stator Between part, on the basis of the plane that said stator and mover two axial line determine, first centered by the axial line of stator, successively Doing the 4 of stator circumference decile, 6,8,10 or 12 equidistant points, above-mentioned each equidistant point is crossed to form with stator medial wall respectively 4,6,8,10 or 12 straight lines, at above-mentioned 4,6,8,10 or 12 linear positions, set gradually 4,6,8,10 or 12 respectively Blade, each blade is cut with scissors with stator medial wall respectively by 4,6,8,10 or 12 articulated mountings respectively at above-mentioned each intersecting straight lines Connect;Again centered by the axial line of mover, take turns doing the 4 of mover circumference equal dividing, 6,8,10 or 12 equidistant points, with mover axle Heart line is axial line, with two of the inside and outside radius sum more than mover cylinder/and in the lump less than the outer half of mover cylinder Footpath is radius, does cylinder, and this face of cylinder forms 4,6,8,10 or 12 phases respectively with above-mentioned 4,6,8,10 or 12 equidistant points Hand over straight line, respectively with above-mentioned 4,6,8,10 or 12 intersecting straight lines as axial line, with mover lateral wall cylindrical radius with above-mentioned newly The difference doing cylindrical radius is radius, opens 4,6,8,10 or 12 cylindrical holes on mover, and respectively in above-mentioned cylindrical hole Respectively setting together that footpath is with high 4,6,8,10 or 12 cylindrical axis bodies, this axis body can turn with each axial line for axle respectively in each hole Dynamic, each axis body is respectively opened a groove by this axis body axial line, well width is identical with vane thickness, and the degree of depth of groove is more than The radius of this cylinder axis body, blade is respectively provided in the groove of each axis body;On left and right two end caps of stator, the most all Setting up 4,6,8,10 or 12 arcuate apertures put separately, each hole on left end cap is medium input channel, and each hole on right-hand end lid is Medium output channel;And divided equally by degree angle 4,6,8,10 or 12 cylindrical holes are set, each hole is each hinge of stator vane respectively The hole, location of spindle;Input and output two control valve of medium is identical, respectively external face left and right with stator laminating, with bent axle Spindle centerline be that axial line is arranged, left and right two control valve presses axle phase phase contrast 180 degree installations, and left side is that medium inputs control Valve, right side is medium output control valve;The housing of device is left total between end cap and stator left end cap and the right total end of housing of device Two spaces formed respectively between lid and stator right end cap are the excessive input-output spaces of medium, and left side is that medium inputted Degree space, right side is that medium exports excessive space;Bent axle right-hand member is moment of torsion input/output terminal.
The invention has the beneficial effects as follows
Improving existing vane pump, during operating, the stator of pump is motionless, and the mover of pump only does two coordinates under the driving of built-in bent axle The most mobile, blade only radially periodically stretches and around vane hinge axial line periodic wobble, related elements abrasion is little, pump Service life long, pump volume space sealing can reach the level of plunger displacement pump, and the pressure of its output liquid is than traditional leaf Sheet pump improves more than 10 times, and the present invention can advance the upgrading of vane pump.The present invention inputs highly pressurised liquid, the song that mover is built-in Axle rotates, and can be changed into novel hydraulic motor.
