Abstract
The utility model provides a can timely oil absorption rotor formula oil pump, include the pump body, pump cover, drive gear, rotor shaft and install at epaxial inner rotor of rotor and external rotor, the one end of rotor shaft is installed in the shaft hole of the pump body, and the other end is installed in the shaft hole of pump cover, and drive gear installs in the end of the arbitrary one end of rotor shaft, all installs the bush in the shaft hole of the pump body and pump cover, wherein is equipped with an axial air discharge duct between the outer peripheral face of shaft hole wall and the bush of the pump body, the position of air discharge duct is close to the end that produces oil of oil pump. The beneficial effects of the utility model are that: through increase an air discharge duct at the end that produces oil, just can make the gaseous air discharge duct of in time following in the airtight space discharge when oil pump initial start to the oil pressure is set up in rapid oil absorption, and the check valve is opened under the effect of oil pressure, and fluid can get into lubricated oil duct and lubricate the engine.
Description
Technical field
This utility model relates to a kind of engine lubrication system parts, particularly to a kind of rotor-type oil pump.
Background technology
Rotor-type oil pump is made up of the pump housing, armature spindle, internal rotor, outer rotor and pump cover etc..Internal rotor is fixed on rotor
On axle, crankshaft toothed wheel directly or indirectly driving, internal rotor and outer rotor eccentric setting, internal rotor drives outer rotor together along same
One direction rotates.On the tooth form line of each tooth of inner and outer Rotator, total energy mutually holding point contact condition, so, inside and outside
Just several working chambers are formed between rotor.When some working chamber turns over from oil sucting cavity, volume increases, and produces vacuum, machine oil
It is inhaled into working chamber from fuel feed hole, along with being rotated further of inner and outer Rotator, when this working chamber forwards the position that pumping cavity communicates to,
Volume diminishes, and oil pressure raises, and machine oil is pressed into oil leab from oil outlet through pumping cavity.
Owing to the oil outlet end of this lubricating oil pump has individual check valve on the engine, oil pump after only check valve is opened, just can be made
The fluid of oil outlet end is by lubrication electromotor, but check valve needs the most just can open.In oil pump initial start
Time, because the existence of check valve, it is the space that an approximation is airtight between oil outlet end and the check valve of oil pump, so turns when oil pump
After son starts to rotate, because the existence of confined space, working chamber cannot oil suction in time, it is impossible to set up rapidly oil pressure, check valve difficulty
To open, finally result in electromotor and cannot start even part of damage smoothly.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can the rotor-type oil pump of oil suction in time.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that the rotor of the timely oil suction of a kind of energy
Formula lubricating oil pump, including the pump housing, pump cover, travelling gear, armature spindle and the internal rotor being arranged on armature spindle and outer rotor, described
One end of armature spindle is arranged in the axis hole of the pump housing, and the other end is arranged in the axis hole of pump cover, and travelling gear is arranged on armature spindle
Arbitrarily the termination of one end, is mounted on lining in the axis hole of the pump housing and pump cover, the axis hole wall of its middle pump body and the periphery of lining
An axial air discharge duct it is provided with, the oil outlet end being located proximate to lubricating oil pump of described air discharge duct between face.
In one embodiment, described air discharge duct is opened on the axis hole wall of the pump housing.
In one embodiment, described air discharge duct is opened on the outer peripheral face of lining.
Preferably, the cross section of described air discharge duct is crescent.
Preferably, described outer rotor is provided with multiple oil-through hole.
The beneficial effects of the utility model are: by increasing an air discharge duct at oil outlet end, just can be in oil pump initial start
Time, making the gas in confined space discharge from air discharge duct in time, thus oil pressure is set up in oil suction rapidly, check valve is in the effect of oil pressure
Under be opened, fluid gets enter into oil leab and is lubricated electromotor.

Fig. 1 is the overall structure schematic diagram of this utility model embodiment；
Reference is:
1 pump housing 2 pump cover 3 travelling gear
4 armature spindle 5 internal rotor 6 outer rotors
7 lining 8 air discharge ducts.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, this utility model is made further with accompanying drawing below in conjunction with embodiment
Explanation, the content that embodiment is mentioned is not to restriction of the present utility model.
In description of the present utility model, it is to be understood that term " first ", " second " are only used for describing purpose, and
It is not intended that indicate or imply relative importance or the implicit quantity indicating indicated technical characteristic.At this utility model
Description in, " multiple " are meant that two or more, unless otherwise expressly limited specifically.Retouch of the present utility model
In stating, it should be noted that unless otherwise prescribed and limit, term " is installed ", " being connected ", " connection " should be interpreted broadly, example
As, can be to be mechanically connected or electrical connection, it is also possible to be the connection of two element internals, can be to be joined directly together, it is also possible to be logical
Cross intermediary to be indirectly connected to, for the ordinary skill in the art, described term can be understood as the case may be
Concrete meaning.
As it is shown in figure 1, preferred embodiment of the present utility model is: the rotor-type oil pump of the timely oil suction of a kind of energy, including
The pump housing 1, pump cover 2, travelling gear 3, armature spindle 4 and the internal rotor 5 being arranged on armature spindle 4 and outer rotor 6, on outer rotor 6
Being provided with multiple oil-through hole, one end of described armature spindle 4 is arranged in the axis hole of the pump housing 1, and the other end is arranged on the axis hole of pump cover 2
In, travelling gear 3 is arranged on armature spindle 4 and passes on the termination of the pump housing 1 one end, is mounted in the axis hole of the pump housing 1 and pump cover 2
Lining 7, is wherein provided with an axial air discharge duct 8, this aerofluxus at the axis hole wall of the pump housing 1 near the position of the oil outlet end of lubricating oil pump
