Description
Technical field
The present invention relates to machine oil pump technical field, a kind of especially rotor-type oil pump pump housing.
Background technique
Rotor-type oil pump is made of shell, internal rotor, outer rotor and pump cover etc., the recessed gear ratio internal rotor of outer rotor
Raised teeth number is one more, and such inner and outer Rotator nonsynchronous rotation in the same direction, rotor tooth form tooth Profile Design must make rotor go to any angle
When spending, can mutually coordinate point contact on the tooth form profile of each tooth of inner and outer Rotator.In the oil inlet side of rotor chamber, since rotor is de-
Engagement is opened, volume is gradually increased, and generates vacuum, and machine oil is inhaled into, and rotor continues to rotate, and machine oil is brought to the fuel-displaced of rotor chamber
Side, at this moment, rotor just enter engagement, reduce this cavity volume, and oil pressure increases, and machine oil squeezes out between cog and passes through out rotor
Chamber force feed is gone out.In this way, machine oil is just constantly inhaled into and extrudes with the continuous rotation of rotor.
The existing lubricating oil pump pump housing usually respective rotor bottom of chamber portion be provided with cooperation pump cover oil inlet and oil outlet into
Oil groove and out oil groove, since oil pressure is higher when entering the fuel-displaced side of rotor chamber for machine oil, and the groove bottom of oil groove and out rotor out
There are certain differences in height for the bottom surface of chamber, are easy to cause machine oil not suitable enough when flowing into out in oil groove from rotor chamber bottom surface in this way
Freely, or even it will increase the intracorporal pressure oscillation of pump.
Summary of the invention
Problem to be solved by this invention is to provide a kind of rotor-type oil pump pump housing, and machine oil can be made to enter rotor
It is more smooth when chamber, largely reduce the pressure oscillation in pump.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of rotor-type oil pump pump housing, including
Ontology, offers the rotor chamber for installing internal rotor and outer rotor on the ontology, the bottom of the rotor chamber be equipped with axis hole,
Oil-feed tank and out oil groove, the arc-shaped and rotation direction setting along internal rotor of the oil groove out, the preceding end slot of the oil groove out
Wall surface is equipped with Oil Guide slope.
Preferably, the middle part on the Oil Guide slope is equipped with the arcwall face swelled upwards along its width direction.
Preferably, the first groove is offered along its height on the rotor chamber inner wall of the oil-feed tank, described first
The groove bottom of the lower end connection oil-feed tank of groove, offers second along its height on the rotor chamber inner wall of oil groove out
The lower end of groove, second groove connects out the groove bottom of oil groove.
It is highly preferred that the ontology is equipped with multiple weight loss grooves.
It is highly preferred that the lateral surface of the ontology is arranged at intervals with three interconnecting pieces outwardly protruded, the interconnecting piece is opened
Equipped with mounting hole.
It is highly preferred that being connected with reinforcing rib between the interconnecting piece and ontology.
The beneficial effects of the present invention are: internal rotor, outer rotor, armature spindle, pump cover are pumped into the pump housing in the rotator type mechanism
Ontology on install after, at work, with the rotation of rotor, machine oil enters rotor from the oil inlet side of rotor chamber to lubricating oil pump
When the fuel-displaced side of chamber, the machine oil of body bottom portion can slide into out in oil groove along the Oil Guide slope of fuel-displaced front of the slot trough wall surface,
Flow process is more smooth, largely reduces the pressure oscillation in pump.
