Description
Technical field
The utility model is related to a kind of lubricating oil pump.
Background technology
Lubricating oil pump is increasingly taken seriously as the conventional corollary equipment of engine, current lubricating oil pump be divided into gear pump and
The major class of impeller pump two, wherein gear pump generally comprise lower cover, gear cavity and the upper cover plate being sequentially overlapped together, in gear cavity
A pair of intermeshing gears are inside installed, when pinion rotation, the side of gear can form vacuum state, machine oil be inhaled into by
In the small-sized oil pocket that the teeth groove of gear is formed, the opposite side of gear is then fed to.But the mechanism of current lubricating oil pump is more multiple
Miscellaneous so that the assembling of lubricating oil pump is more complicated, the manufacturing cost of lubricating oil pump can not be effectively reduced.
Utility model content
To solve the above problems, the utility model proposes a kind of lubricating oil pump, it includes pump cover, the pump being superimposed
Body, driving shaft and driven gear shaft, are provided with gear cavity in the pump housing, and intermeshing driving gear is provided with gear cavity
And driven gear, driving shaft through pump cover and being fixedly connected with driving gear, the driven gear shaft through pump cover and with it is driven
Pinion rotation is connected；The gear cavity has a bottom plate, fuel feed hole is offered on bottom plate, being connected with fuel sucking pipe in fuel feed hole leads
Pipe；Collecting filter for filtering is installed on bottom plate, the fuel feed hole connects collecting filter through fuel sucking pipe conduit.
Further, driving shaft fixing hole and driven gear shaft fixing hole, one end of the driving shaft are provided with bottom plate
It extend into the driving shaft fixing hole, one end of the driven gear shaft is extend into the driven gear shaft fixing hole, actively
One end of axle fixing hole towards collecting filter is provided with plug.The two ends of driving shaft and driven gear shaft are separately fixed at pump lid and bottom
On plate, it is ensured that the stability of axle, while being provided with plug in one end of driving shaft fixing hole towards collecting filter, the plug is to master
Moving axis plays a part of positioning, is conducive to being accurately positioned for driving shaft.
Further, the lubricating oil pump also includes alignment pin, and one end of the alignment pin is entered in the pump housing through pump cover, the other end
In pump cover.Alignment pin makes the positioning between pump cover and the pump housing more accurate.
Further, guide pipe is provided with pump cover, guide pipe extends towards the direction away from the pump housing, the one of the driving shaft
End is stretched out to form power intake from guide pipe.It is provided with the one end of guide pipe away from the pump housing for being connected on engine
Flange.Guide pipe is directly formed on pump cover, i.e., guide pipe is integrally formed with pump cover, both ensure that and has been connected between guide pipe and pump cover
The stability that connects, it is to avoid the problem of the brought positioning of secondary connection is inaccurate is needed in split-type structural.While monoblock type knot
Structure reduces the expense of mounting surface processing.
In the utility model, the housing of lubricating oil pump only includes the pump housing and pump cover, and the formation of gear cavity is only formed by the pump housing, and
It will be arranged on for the collecting filter for filtering machine oil outside the pump housing so that simplifying the structure for lubricating oil pump, lubricating oil pump can be effectively reduced
The processing capacity of mounting surface, and reduce the manufacturing cost of lubricating oil pump.
