Description
Technical field
The present invention relates to a kind of engine lubrication system component, in particular to a kind of rotor-type oil pump.
Background technique
Rotor-type oil pump is made of the pump housing, internal rotor, outer rotor, armature spindle and pump cover etc..The pump housing is equipped with rotor chamber,
Internal rotor and outer rotor are located in rotor chamber, and internal rotor is fixedly mounted on armature spindle, are directly or indirectly driven by crankshaft toothed wheel,
The eccentricity at internal rotor center and outer rotor center is e, and internal rotor drives outer rotor to rotate in the same direction together.In rotor chamber
Bottom be equipped with semi-moon shaped oil-feed tank and oil groove out, the line at internal rotor center and outer rotor center is line of eccentricity, the bias
Entire rotor chamber is divided into oil inlet side and oil extraction side by line.In the prior art, semi-moon shaped oil-feed tank is entirely located in rotor chamber
Oil inlet side, it is semi-moon shaped go out oil groove be entirely located in the oil extraction side of rotor chamber.
Since commercial vehicle is different in flow demand of the different phase to lubricating oil pump, in low speed, volumetric efficiency demand is high, high
Volumetric efficiency demand is low when fast, and can all have flow more than needed at a high speed according to the lubricating oil pump of low speed volumetric efficiency design.To understand
Certainly this problem, the prior art are all to limit output flow by increasing pressure limiting valve, will lead to manufacturing cost height, function in this way
Rate consumption is big.
Summary of the invention
It can solve what high speed flow was had more than needed without increasing pressure limiting valve just the technical problem to be solved in the present invention is to provide a kind of
Rotor-type oil pump.
In order to solve the above-mentioned technical problem, the technical scheme is that a kind of can solve high speed flow rotor more than needed
Formula lubricating oil pump, including the pump housing, pump cover, internal rotor, outer rotor, armature spindle, the pump housing are equipped with for accommodating internal rotor and outer
The rotor chamber of rotor, the bottom of the rotor chamber are equipped with semi-moon shaped oil-feed tank and out oil groove, and setting in oil-feed tank and goes out
The center of axis hole between oil groove, the relatively described rotor chamber in the center of the axis hole is set for the eccentric, by the center of the axis hole
It is connected to form a line of eccentricity with straight line with the center of the rotor chamber, which runs through oil-feed tank and out oil groove simultaneously.
In above-mentioned technical proposal, since internal rotor is mounted on armature spindle, armature spindle is mounted in the axis hole of the pump housing, because
This, the center of axis hole is equal to the center of internal rotor, and the center of rotor chamber is equal to the center of outer rotor.Due to connecting shaft hole
The both ends of the line of eccentricity at center and the center of rotor chamber extend through oil-feed tank and out oil groove, so that it is inswept just to change rotor
Effective area makes effective oil inlet area become smaller, and is equivalent to oil-feed tank and oil groove is ganged up out, in this way will in high speed
Oil inlet is insufficient, to achieve the purpose that reduce volumetric efficiency, does not need additionally to increase pressure limiting valve to limit output flow.
Detailed description of the invention

Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.
In the description of the present invention, it is to be understood that, term " first ", " second " are used for description purposes only, and cannot
It is interpreted as indication or suggestion relative importance or implicitly indicates the quantity of indicated technical characteristic.In description of the invention
In, the meaning of " plurality " is two or more, unless otherwise specifically defined.In the description of the present invention, it needs
Illustrate, unless otherwise specified and limited, term " installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be
Mechanical connection or electrical connection, the connection being also possible to inside two elements can be directly connected, and can also pass through intermediary
It is indirectly connected, for the ordinary skill in the art, can understand the concrete meaning of the term as the case may be.
As shown in Figure 1, 2, a kind of to can solve high speed flow rotor-type oil pump more than needed, including the pump housing 1, pump cover 2, rotor
Axis 3, internal rotor 4, outer rotor 5, the pump housing are equipped with the rotor chamber 11 for accommodating internal rotor 4 and outer rotor 5, the rotor
The bottom of chamber 11 is equipped with semi-moon shaped oil-feed tank 13 and oil groove 14, and the axis being arranged between oil-feed tank 13 and out oil groove 14 out
The center in hole 12, the relatively described rotor chamber 11 in the center of the axis hole 12 is set for the eccentric, by the center of the axis hole 12 and institute
The center for stating rotor chamber 11 is connected to form a line of eccentricity with straight line, which runs through oil-feed tank 13 and out oil groove 14 simultaneously.
In above-mentioned technical proposal, since internal rotor is mounted on armature spindle, armature spindle is mounted in the axis hole of the pump housing, because
This, the center of axis hole is equal to the center of internal rotor, and the center of rotor chamber is equal to the center of outer rotor.Due to connecting shaft hole
The both ends of the line of eccentricity at center and the center of rotor chamber extend through oil-feed tank and out oil groove, so that it is inswept just to change rotor
Effective area makes effective oil inlet area become smaller, and is equivalent to oil-feed tank and oil groove is ganged up out, in this way will in high speed
Oil inlet is insufficient, to achieve the purpose that reduce volumetric efficiency, does not need additionally to increase pressure limiting valve to limit output flow.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart from the technical program design under the premise of it is any obviously replace it is within the scope of the present invention.
In order to allow those of ordinary skill in the art more easily to understand the improvements of the present invention compared with the existing technology, this
Some attached drawings of invention and description have been simplified, and for the sake of clarity, present specification is omitted some other members
Element, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the contents of the present invention.
