Background technique
At present, pump as element most important in hydraulic system, current extensive use mainly contain gear pump, vane pump and plunger pump three kinds, but each own pluses and minuses.The advantage of gear pump is that structure is simple, reliable operation, but volumetric efficiency is low, noise is large, flow pulsation is obvious; The advantage of vane pump be discharge capacity compared with large, uniform flow, noise are little, but functional reliability is poor, complex structure; The advantage of plunger pump is compact structure, easy to process, specific power volume is little, but cost is high, complex structure, responsive to oil contamination.Therefore market needs a kind of novel oil hydraulic pump.
Summary of the invention
The present invention is mainly for above problem, there is provided a kind of on the basis of rotary engine, this duplex triangle rotor type oil hydraulic pump is designed by the change to structure, the stagger mode at phase angle of similar straight engine is adopted to reach the object reducing operational shock, main feature is that flow is large, efficiency is high, volume is little, structure is simple, operate steadily shock-free oil hydraulic pump, and its technological scheme adopted is as follows:
A kind of novel duplex three-apexed rotor oil hydraulic pump comprises: front rotor oil outlet one-way valve, front rotor, front rotor in line check valve, pump case, rear rotor oil outlet one-way valve, rear rotor, rear rotor in line check valve and input shaft, described front rotor oil outlet one-way valve is fixed in pump case body surface body top, front rotor in line check valve is fixed in pump case body surface body bottom, rear rotor oil outlet one-way valve is fixed in pump case body surface body top, rear rotor oil outlet one-way valve position and front rotor oil outlet one-way valve are on the same axis, rear rotor in line check valve position and front rotor in line check valve are on the same axis, rear rotor in line check valve is fixed in pump case body surface body bottom, input shaft is rotationally connected through pump case side and pump case, the front gear of front rotor and input shaft is rotationally connected, rear rotor and input shaft backgear are rotationally connected.
On technique scheme basis, described front rotor and rear rotor are all be connected with the front and back pinion rotation of input shaft by the mode of seamed docking, by the front rotor of centrifugal force whipping and rear rotor during rotation, corresponding four bolts hole of pump case base position, front rotor and rear rotor all adopt triangular rotor shape, front rotor three sidelines adopt the camber line with radian, and rear rotor three sidelines adopt the camber line with certain radian.
The present invention is on the basis of rotary engine, this duplex triangle rotor type oil hydraulic pump is designed by the change to structure, adopt the stagger mode at phase angle of similar straight engine to reach the object reducing operational shock, main feature is that flow is large, efficiency is high, volume is little, structure is simple, operates steadily without impact.
