Description
Technical field
The present invention relates to a kind of engine lubrication system component, in particular to a kind of gear type oil pump.
Background technique
Existing lubricating oil pump, it usually needs the high pressure oil in oil outlet region is guided into the pump housing and pump cover by oil-way
Axis hole position, for being lubricated between axis hole and shaft.In addition, lining would generally be pressed in axis hole in order to avoid abrasion
Set.When the axis hole of the pump housing or pump cover is long, if with a bushing, lubricating oil from high pressure oil end by the gap of bushing and axis into
Enter, it is difficult to the outer one end of sufficient lubrication.
Summary of the invention
The technical problem to be solved in the present invention is to provide the gear type oil pumps that one kind is capable of fast lubricant bushing.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of tooth for capableing of fast lubricant bushing
Wheeled lubricating oil pump, including the pump housing, pump cover, driving shaft, driving gear, driven shaft, driven gear；The driven gear is rotationally
It is mounted on the middle part of the driven shaft, one end of the driven shaft is fixedly mounted on the pump housing；The driving gear is fixedly mounted
At the middle part of the driving shaft, the both ends of the driving shaft are installed in rotation on respectively in the axis hole of the pump housing and pump cover, described
There are two bushings, two bushing intervals to be arranged in the axis hole for making the pump housing or pump cover and form first for press fitting in the axis hole of the pump housing or pump cover
Annular groove is additionally provided with one on the pump housing or pump cover for being connected to the inclined oil hole of air of first annular groove and high-voltage oil cavity.
In above-mentioned technical proposal, since dress is formed between two bushings there are two bushing in the axis hole of the pump housing or pump cover
Then high pressure oil in lubricating oil pump high-voltage oil cavity is introduced into first annular groove by first annular groove by inclined oil hole of air, this
Sample can just make lubricating oil be directly entered the middle part of axis hole, fast lubricant bushing and driving shaft surface, and be conducive to outward
End provides sufficient lubricating oil and is lubricated.
The further technical solution of the present invention is: there are two bushing, two bushings for press fitting in the axis hole of the driven gear
Interval, which is arranged in the axis hole for making driven gear, forms second annular groove, and the driven gear is in the position of corresponding second annular groove
Install the oil-through-hole of a radial direction.Since driven gear is rotated around driven shaft, when oil-through-hole rotates to higher-pressure region, high pressure oil
Second annular groove can be entered by oil-through-hole, then driven shaft surface and bushing are provided by the gap of driven shaft and bushing
Lubrication, when oil-through-hole rotates to low-pressure area, the high pressure oil in second annular groove can be discharged to low pressure chamber by oil-through-hole, such as
This iterative cycles.
Further, oil guide groove is equipped on two end faces of the driven gear.Parts of lubricating oil can thus be made
Enter the gap of driven shaft and bushing by oil guide groove, form bilateral oil inlet lubricating, makes the lubrication on bushing and driven shaft surface more
Sufficiently.
Preferably, the outer openings of the oil-through-hole are arranged at the tooth root of driven gear.

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 Figures 1 to 4, the preferred embodiment of the present invention is: one kind capableing of the gear type oil pump of fast lubricant bushing,
Including the pump housing 1, pump cover 2, driving shaft 3, driving gear 4, driven shaft 5, driven gear 6, transmission gear 7；Driven gear 6 can be rotated
Ground is mounted on the middle part of driven shaft 5, and one end of driven shaft 5 is fixedly mounted in an interference fit on the pump housing 1；Driving gear
4 are fixedly mounted on the middle part of driving shaft 3, and the both ends of driving shaft 3 are installed in rotation on respectively in the axis hole of the pump housing 1 and pump cover 2,
Bushing 8 is pressed in the axis hole of the pump housing 1 and pump cover 2, there are two bushing 8, two bushings 8 for press fitting in the axis hole of middle pump body 1
Interval setting makes to form first annular groove 9 in the axis hole of the pump housing 1, be additionally provided on the pump housing 1 one it is first annular recessed for being connected to
The inclined oil hole of air 10 of slot 9 and high-voltage oil cavity.So that lubricating oil is directly entered the middle part of axis hole, fast lubricant bushing 8 with
3 surface of driving shaft, and the sufficient lubricating oil of outside side offer is provided and is lubricated.
As shown in Figure 2,3, there are two bushings 8, two interval of bushing 8 settings to make driven for press fitting in the axis hole of driven gear 6
