Description
Technical field
The utility model is related to engine lubrication system, the rotor engine oil pump used on particularly a kind of commercial vehicle engine.
Background technology
With continuing to develop for engine technology, to the technical requirements of the rotor engine oil pump of engine lubrication system increasingly
It is high.For example, further to improve the manufacture level of commercial vehicle engine and reducing commercial vehicle engine manufacturing cost, it is necessary to one kind
Design on the large-scale drive end bearing bracket of commercial vehicle engine diversification combination and Engine Matching and by engine crankshaft gear drive
The lightweight rotor engine oil pump with idle gear.In addition, in order to require lubricating oil pump for commercial vehicle engine in various conditions of work
Lower offer oil pressure stabilization, flow are abundant, the lubricating oil of reliable working performance, and pair lubricating oil pump matched with commercial vehicle engine exists
Oil flow rate, pressure and the main screw lift that installation dimension, three dimensions, engine lubrication system need under certain rotating speed are all
Propose new requirement.
The general impeller pump with idle gear structure, using ironcasting, idle gear shaft is the pump housing with pump housing interference fit
Can.Due to lightweight requirements to be adapted to, the pump housing can only use aluminum casting to present lubricating oil pump, and the aluminum casting pump housing and idle gear shaft mistake
The power that is full of is restricted, therefore idle gear shaft is likely to occur in motion process releases.
Utility model content
The purpose of this utility model is to solve the problems, such as above-mentioned prior art, there is provided one kind is prevented from lazy tooth
Wheel shaft is released, and using the lubricating oil pump of aluminium alloy pump body.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：A kind of use aluminium alloy pump body
Lubricating oil pump, including the pump housing, idle gear shaft, idle gear component, the idle gear component are arranged on idle gear shaft, the idle gear
Axle interference is arranged in the idle gear axis hole of the pump housing, and a counterbore is provided with the idle gear axis hole lower end of the pump housing, described heavy
Centring ring is installed, the centring ring is interference fit with counterbore, and lower end and the centring ring interference of the idle gear shaft are matched somebody with somebody in hole
Close, the idle gear shaft is steel material with centring ring.
Preferably, the outer face of the centring ring is concordant with pump housing mounting surface.
In one embodiment, the counterbore and centring ring are circle.
In one embodiment, the counterbore and centring ring are polygon.
The beneficial effects of the utility model are：By being provided with a counterbore at the idle gear axis hole lower end of the pump housing, and
One centring ring is installed in counterbore, makes centring ring and counterbore interference fit, and match somebody with somebody the lower end of idle gear shaft and centring ring interference
Close, because the idle gear shaft and centring ring are steel material, can thus strengthen the tightness of idle gear shaft, it is to avoid motion
During the phenomenon that releases of idle gear shaft occur.
Brief description of the drawings
Fig. 1 is the lubricating oil pump overall structure diagram in the utility model embodiment；
Reference is：
1 --- idle gear shaft 2 --- idle gear shaft component
3 --- pump housing 4 --- centring rings.

The orientation or position relationship of the instructions such as " clockwise ", " counterclockwise " be based on orientation shown in the drawings or position relationship, be only for
Be easy to description the utility model and simplify describe, rather than indicate imply signified device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that indicating or implying relative importance
Or the implicit quantity for indicating indicated technical characteristic.In description of the present utility model, " multiple " be meant that two or
Two or more, unless otherwise expressly limited specifically., it is necessary to illustrate in description of the present utility model, unless otherwise rule
Fixed and restriction, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be mechanically connect or electrically connect,
Can be two connections of element internal, can be joined directly together, it is also possible to be indirectly connected to by intermediary, for this area
Those of ordinary skill for, can as the case may be understand the concrete meaning of the term.
As shown in figure 1, a kind of lubricating oil pump of use aluminium alloy pump body, including the pump housing 3, idle gear shaft 1, idle gear component 2,
The idle gear component 2 is arranged on idle gear shaft 1, and the interference of the idle gear shaft 1 is arranged in the idle gear axis hole of the pump housing 3,
Be provided with a counterbore at the idle gear axis hole lower end of the pump housing 3, centring ring 4 be installed in the counterbore, the centring ring 4 with
Counterbore is interference fit, and lower end and the interference fit of centring ring 4 of the idle gear shaft 1, the idle gear shaft 1 are equal with centring ring 4
It is steel material；The outer face of the centring ring 4 is concordant with the mounting surface of the pump housing 3.The counterbore and centring ring 4 are circle,
