Fusion gerotor pump and motor
[technical field]
The invention belongs to mechanical manufacturing field.
[background technology]
Current various displacement pumps performance substantially and pluses and minuses are as follows:
Definitely at the uniform velocity discharge capacity output cannot in theory be accomplished;Definitely at the uniform velocity torque output.
Vane pump:The structure of vane pump is complicated compared with gear pump, but its operating pressure is higher, and flow pulsation is little, and work is flat Surely, noise is less, lasts a long time. so it is widely used in low hydraulic pressure in the special purpose machine tool in machine-building, transfer matic etc. In system, but its complex structure, poorly, the pollution to fluid is also more sensitive for oil absorption;, the improved high pressure leaf of structure The maximum operating pressure of piece pump is up to 16.0~21.0Mpa.Vane pump is made up of rotor, stator, blade and end cap etc. and stator has There is cylindrical form interior surface, there is eccentric throw between stator and rotor. blade is mounted in rotor slot, and can be slided in groove, when rotor is returned When turning, due to the effect of centrifugal force, blade is set to abut against stator inner wall, so in stator, rotor, between blade and both sides oil distribution casing The work space of several sealings is just formed, when rotor is turned round, blade gradually stretches, and interlobate work space gradually changes Become, in rotor each rotation, each work space completes an oil suction and force feed, therefore referred to as single acting vane pump to vane pump. Rotor ceaselessly rotates, pump just constantly oil suction and oil extraction.
Feature:Operating pressure is higher, pulses little, and noise is less, lasts a long time.
Shortcoming:Rotating speed is relatively low, and flow is medium.
Common gear pump:The concept of gear pump is very simple, i.e., its most basic form two is equivalently-sized Gear is intermeshed rotation in a close-fitting housing, and the similar figure of eight in inside of this housing, two gears are mounted in The inside, the external diameter of gear and both sides are fitted close with housing.Most basic form is exactly that two equivalently-sized gears are tight at one Intermeshing rotation in leakproof fit housing, the similar figure of eight in inside of this housing, two gears are mounted in the inside, gear External diameter and both sides are fitted close with housing.The material for coming from extruder is entered in the middle of two gears, and full of this in suction inlet One space, as the rotation of tooth is along housing motion, finally discharges when two teeth are engaged.
Feature:Operating pressure is more medium, pulses larger, lasts a long time, and rotating speed is higher.
Shortcoming:Pulsation is larger, and flow is less.
Crescent gear pump (impeller pump):Crescent gear pump has many advantages, and compact conformation, small volume, part is few, turns Speed may be up to 10000r/mim, and stable movement, noise is low, and volumetric efficiency waits to have the disadvantage that flow pulsation is big compared with high, the manufacture of rotor Complex process etc., has adopted at present powder metallurgy pressing molding. and with the development of industrial technology, the application of cycloid gear pump will More and more extensive crescent gear pump can be inverted just, can be used as hydraulic motor.
Feature:Working speed is relatively low, pulses little, and noise is less, and rotating speed is higher.
Shortcoming:Flow is medium, the life-span is general.
Piston pump:Piston pump is applied to high pressure, the particularly occasion of low discharge, flow and is less than 100 meters 3/ hour, discharges pressure When power is more than 9.8 MPas, its higher efficiency and good runnability are more shown.Its intake performance is good, can aspirate various The liquid of different medium, different viscosities.Therefore, it is raw in petro chemical industry, machine building industry, papermaking, food processing, medicine The application of the aspects such as product is very wide.Low-medium speed piston pump speed is low, can be dragged with manual operation and animal power, it is adaptable to rural water supply and little Type is irrigated.Flow Q=0.71~6000 meter of piston pump 3/ hour, discharge pressure P2≤39.2 MPa, in most cases P2 ≤ 24.5 MPas.
Feature:Operating pressure is very high, pulses less, lasts a long time.
Shortcoming:Flow is big, and rotating speed is medium, and volume is big, and noise is larger.
[content of the invention]
Fusion gerotor pump and motor;The main body of the structure be by:Fusion rotor (1), structural cavity body (2), thrust bullet Reed (3) or axial limiting construction and gear piece (4) or the composition such as body slide assemblies or dead axle not rounded pulley assembly;Fusion rotor (1) be mounted among structural cavity body (2) as pivoting part, and with the inner surface of structural cavity body (2) be fitted close or It is clearance fit relationship, the function that thrust spring piece (3), thrust spring piece (3) is needed during tight fit is to maintain itself and structure The inner surface of cavity (2) is to be fitted close;Gap needs axial limiting to construct when coordinating, and axial limiting construction is used:Card Spring, catch or rolling bearing;The latent structure of fusion rotor (1) is at least 2 conduits, and the head and the tail trend of conduit (6) is being justified On the direction in week, axial location diverges to a certain distance;And the head and the tail of conduit (6) have the coincidence angular area that section fusion is successively decreased (distribution angle scope:About slightly larger than hemicycle week, now 2 respectively account for half circumference to maximum situation, full of whole in angle Individual circumference, forms the angular regions of 2 overlaps);Gear piece (4) or body slide assemblies or dead axle not rounded pulley assembly are arranged on thing On the input port of material and delivery outlet, the tooth tip portion of gear piece (4) or body slide assemblies or dead axle not rounded pulley assembly is touched to close and melted On conjunction rotor (1) surface in the groove of conduit;The fusion that the elastic force deformation direction of the teeth portion of gear piece is touched with the teeth portion of gear piece Rotor (1) normal to a surface direction is identical or contrary;So the tooth tip portion coincideing with conduit of gear piece will be with fusion rotor (1) Rotation and contact slide in the channel, conduit is jumped out with the termination of conduit, slide into the sideway stance of fusion rotor slotless, Go round and begin again;When working as hydraulic pump body, the gear piece (4) or body slide assemblies or dead axle installed in material input is non- Round and smooth wheel assembly will play a part of extruded material;When sliding in conduit due to tooth tip portion, when meeting in rotation direction tooth is caused When tip is more close to by wall (5), tooth tip portion has the effect of sealing conduit and the material in conduit is released into conduit, produces pump Body discharge, empty the conduit of material by with structural cavity body inwall form vacuum space, the conduit spatial rotational of portion's vacuum arrives Material is filled after material input again;When working as hydraulic motor, need to be provided with pressure relief valve (pressure releasing structure:In fortune The gear piece (4) of row low-pressure area or body slide assemblies are nearby or the inner surface of structural cavity body (2) of dead axle not rounded pulley assembly adds Work has with the unidirectional relief hole by effect, and one-way cock ensures that liquid will not be back to the low-pressure area), otherwise hydraulic motor Will not start;The pressure of (highly pressurised liquid) material will cause tooth tip portion to bear pressure so that tooth tip portion is more close to by wall (5) When;Material pressure acts on channel ends surface, produces rotating torque.
When the rotation direction of fusion rotor (1) is caused, when no longer meeting tooth tip portion and being close to by wall (5) in rotation direction, Gear piece (4) or body slide assemblies etc. will lose sealing function;Material or flowed out by eduction valve or circumferential washed open (due to band It is flexible) tooth tip portion outflow.
With the technical characteristic of the difference of other technologies:It is fixed on the gear piece (4) or body slide assemblies in structural cavity body Tooth tip portion or dead axle not rounded pulley are slided in fusion rotor conduit, and the fusion of the coincidence angular area of conduit is successively decreased and referred to:Conduit Sectional area in coincidence angular area linear decrease until to zero, the depth of groove is also just gradually decremented to zero;Axial limiting construction makes It is:Jump ring, catch or rolling bearing;The quantity in groove fusion rotor road is even number, at least needs 4 conduits;Material is defeated Can be on entrance and delivery outlet 1 pair can also be 2, to 3 pairs or multipair.
Axial limiting is constructed:This is a routine techniquess, it is intended that prevent the axial displacement of rotor.
Merging the shape in the external surface work face of rotor (1) can be:The conical surface can also be cylinder. described structure The inner surface of cavity (2) is to be fitted close or clearance fit relationship, is referred to:Structural cavity body, the inner surface of fusion rotor are During cone match, gap can carry out axially opposing displacement to adjust, and wear and tear or make using compensating for from thrust spring Constructed with axial limiting, obtain long-term close surface engagement state;Or structural cavity body, the inner surface of fusion rotor are that cylinder coordinates When, can only axial limiting construction.
Section fusion is successively decreased and is referred to:The sectional area of conduit in coincidence angular area linear decrease until to zero, that is, groove In coincidence angular area, gradually linear decrease is zero to the depth in road;Now contact point works in pairs simultaneously, the linear increase of area, The linear reduction of one area, just plus just compensation is reduced;This is related to the output uniformity of discharge capacity or torque;Computationally, nothing By discharge capacity or torque, the area sum of the gear piece that any one time is absorbed in below conduit surface is all proportional to;Due in mistake The area of the gear piece that (during 2 slotted vanes are while be absorbed in conduit) is absorbed in below conduit surface during crossing, one is linearly to pass Subtract, another is linear increment;Their area sum keeps constant;Thus absolute linear convergent rate is obtained in theory; This is peerless in volume class compiles appearance technology!
The shape in conduit section:Can be trapezoidal, rectangle, arc, narrow wide shape under being most preferably, when with when and tooth When the contact point of narrow wide shape is slidably matched under piece (4) or body slide assemblies or dead axle not rounded pulley assembly, with certainly Own compensating action, abrasion does not affect fit clearance, to the impact very little for sealing.
The pump slightly has similarity with vane pump;But it is essentially different:Must after the moving component abrasion of vane pump Leakage is so produced, and this technology does not then have, because faying face is without edge face structure so that the abrasion of gear piece will not produce gap, Abrasion is equivalent to break-in.
In addition this technology is easy to accomplish atomic discharge capacity;Splendid sealing characteristics.
* the module diagnostic of critical seal is realized:
Gear piece:It is an integrated elastic structure that elastic displacement is realized by shape.
Body slide assemblies:It is to rely on slide rail or ramp member constraint and while uses spring to realize contact and melt Close dynamic Contact under the displacement of rotor (1).
Dead axle not rounded pulley assembly:It is not only to use slide rail or slideway or Spring driving fixed pulley, it is also possible to only make Realize contact with dynamic Contact under the displacement of fusion rotor (1) with the dead axle of not rounded pulley or the rotation of moving axis.
