Embodiment
A preferred embodiment of the present invention as shown in figure 1 to figure 13.As can be seen from the figure, the critical piece of this oil hydraulic pump 100 comprises housing 101, right end cap 102, left end cap 103, live axle 104, rubs wheel 105, isolates bounding means 107 etc.
As can be seen from Figures 6 and 7, be provided with left and right two and be used to install the cavity 106 of rubbing wheel in housing 101, the diameter of this cavity, can rub when making that rubbing wheel is loaded in the cavity therein greater than the diameter of rubbing wheel.
Employed wheel 105 the structure of rubbing is as shown in Figs. 8 to 11 in the present embodiment, wherein, is provided with a restraining groove 110 on the anchor ring of rubbing wheel 105.Accordingly, be provided with isolation bounding means 107 at cavity inner wall, it extend in the restraining groove, be used for limiting and rub wheel and make it and to rotate, and allow to rub wheel suitable activity nargin is arranged, in addition, as shown in Figure 2, this isolation restraining groove 107 also is used to cut off the gap of rubbing between wheel and the cavity inner wall.
As can be seen from Figure 12, the position corresponding with cavity is eccentric structure on the live axle 104, and when rotating under the effect of live axle in external force, the rotary motion trace of this eccentric position can be bigger.Wherein, the internal diameter of rubbing wheel is slightly larger than the diameter at eccentric position place, makes that rubbing wheel 105 can be set on this eccentric position to running fit.When drive shaft turns, can drive and rub wheel and produce and to rub, in the process of rubbing, the outer ring surface of rubbing wheel is the inwall of extrusion chamber successively.
From Fig. 1 and Fig. 7 as can be seen, on the housing of isolating bounding means one side, be provided with liquid entering hole 108, the housing of opposite side is provided with liquid outlet 109, is isolated bounding means 107 between liquid entering hole and the liquid outlet and separates, but can be interconnected by the gap of rubbing between wheel and the cavity.
The working principle of this oil hydraulic pump is shown in Figure 14 A to Figure 14 D, and wherein, lower right part is a liquid entering hole, and lower left quarter is a liquid outlet, and when live axle rotates counterclockwise, can drive and rub the effect that rubs that wheel produces order shown in Figure 14 A, Figure 14 B, Figure 14 C, Figure 14 D, wherein,
(1) from Figure 14 A to Figure 14 B, be positioned at the gap that isolates the bounding means right side and increase gradually, can suck liquid; The gap in left side reduces gradually simultaneously, thereby can be with liquid pressurization output.
(2) from Figure 14 B to Figure 14 C, top is transferred in the gap, right side gradually, can further suck liquid in this process, until liquid entering hole is blocked fully; Simultaneously, the gap in left side further reduces, thus liquid discharge fully, until liquid outlet is blocked fully.
(3) from Figure 14 C to Figure 14 D, the gap on right side increases gradually from zero, begins to suck liquid once more; To be positioned at liquid gap on the left of being expressed to of side clearance simultaneously, and export from liquid outlet.
(4) from Figure 14 D to Figure 14 A, the gap on right side further increases, and further sucks liquid; The gap in left side further reduces simultaneously, thereby further with liquid pressurization output.
The live axle revolution moves a week, above-mentionedly just repeats once above-mentioned four kinds of states, thereby constantly sucks new liquid, and discharges the liquid after pressurized.As seen, by this structure, can be output as highly pressurised liquid rubbing rubbing the gap of rubbing between wheel and the cavity inner wall extruding lower edge and flowing to liquid outlet of wheel by the liquid of liquid entering hole input.The oil hydraulic pump of present embodiment is particularly suitable for the slow-speed of revolution or the fixed occasion of rotary speed unstabilization is pressurizeed to liquid, for example can be used for application number and be 200510120802.7 wind generating unit and system, as oil hydraulic pump wherein, at this moment, rotate by the wind-drive wind wheel, the latter drives drive shaft turns again, rubs the aforementioned effect that rubs of wheel generation thereby make.
During concrete enforcement, above-mentioned housing 101, right end cap 102, left end cap 103, live axle 104, rub wheel 105, cavity 106, the structure of isolating bounding means 107, liquid entering hole 108, liquid outlet 109 and restraining groove 110 also can do suitable change as required.In addition, the cavity that the above-mentioned structure of one cover can only be set in the same housing adds rubs wheel, and the cover cavity that three covers or more said structures also can be set adds rubs wheel, when two covers being set or overlapping more, rub wheel at each, be provided with the corresponding restraining groove of a cover, isolate bounding means, liquid entering hole and liquid outlet.
Add and rub when wheel when being provided with two covers or overlapping cavity more, each liquid entering hole can be connected to same supplying tube, and each liquid outlet is connected to same output tube, that is to say, every suit cavity adds that to rub between the wheel be relation in parallel.Also can will rub the corresponding liquid outlet of wheel and be connected to next rubbing by indusion tube and take turns corresponding liquid entering hole with last one, to rub the corresponding liquid entering hole of wheel with first then and be connected to supplying tube, rub the corresponding liquid outlet of wheel with last and be connected to output tube, at this moment, each overlaps cavity and adds that to rub between the wheel be the mutual relation of series connection, thereby can form secondary pressurization or more times pressurization.
