Gear-box 70 includes the dust cap (not shown) of cavity and seal cavity, and gear-box 70 can be ellipse.
In addition, the dual rotor rotary type displacement pump of the application is in Pear-Shaped, such as Fig. 5, Fig. 6, Figure 10, Figure 11, Figure 12, figure
15th, shown in Figure 16, Figure 17, Figure 19, Figure 20 and Figure 21, the volume of epicoele 8 is less than the volume of cavity of resorption 9.That is, secondary rotor 20
The volume of the epicoele 8 at place is less than the volume of the cavity of resorption 9 at the place of main rotor 10.Specifically, the volume of cavity of resorption 9 can be epicoele 8
Volume 1.5 times, twice, three times, four times or other suitable ratios.Secondary rotor 20 and the synchronous rotary of main rotor 10, rise
To the effect of sealing；Main rotor rotates to form higher-pressure region and low-pressure area, plays a part of output flow.It is only main in the application to turn
Son 10 rotation output flow, that is to say, that only main rotor 10 promote liquid outflow, i.e., only main rotor 10 rotate outwards it is defeated
Outflow, thus rotating speed can reach it is very high.
The application is compared with the hydraulic pump of same rotational speed, and the dual rotor rotary type hydraulic pump internal capacity of the application is big, because
The flow of output is big in this same time.
Dual rotor rotary type hydraulic pump only one of which rotor (i.e. main rotor 10) output flow of the application, rotating speed can reach
To very high, therefore, compared with the hydraulic pump of same volume, more flows can be exported within the identical time.
In above-described embodiment of the application, it is preferable that cam ring is uniformly distributed around the circumference of final drive shaft, such as Fig. 5, figure
6th, shown in Figure 10, Figure 11, Figure 13, Figure 15, Figure 16, Figure 19 and Figure 20.For example, in the embodiment shown in Fig. 6, cam number is
Two, now the angle between two cams is 180 °；In the embodiment shown in Figure 11, cam number is three, now, three
Angle between cam is 120 °.Cam is uniformly distributed, then the volume between the two of arbitrary neighborhood cam and the inwall of pump case 1 is
Equal, identical fluid can be sucked and discharge, thus the dual rotor rotary type displacement pump can export stable flow.
When circumferential non-uniform Distribution of the cam ring around final drive shaft, angle between adjacent cams can any set angle
Degree.For example, when cam number is two, the angle between two cams can be 190 °, 170 °, 160 ° etc..
The dual rotor rotary type displacement pump that the application is provided, simple in construction, handling ease, low cost is lightweight, workspace
Field width, efficiency high, flow are big, and long service life, noise is low, widely used.
