Description
Technical field
The present invention relates to machine oil pump technical field, a kind of especially lubricating oil pump that the lubricating oil convenient for axis leaks.
Background technique
Lubricating oil pump can provide the machine oil of enough pressure and flow as the important component in lubricating system for lubricating system,
When work, the oil inlet that the oil liquid from oil sump first passes through lubricating oil pump is inhaled into oil suction chamber, then is admitted to oil outlet chamber, finally
It is discharged, is sent in the pipeline for needing to lubricate from oil outlet.Lubricating oil pump includes the pump housing, pump cover and axis, and pump cover is mounted on the pump housing
Together, axis extends vertically through the pump housing and pump cover, for the normal operation for guaranteeing axis, needs lubricating oil in axis hole, the lubricating oil is usual
It is introduced from the oil outlet chamber of pump cover, then returned in oil suction chamber by the oil groove that axis hole leaves for pump cover oil suction chamber, forms the interior of lubricating oil
Circulation, although the mode of the lubricating oil draining of the above axis is able to satisfy the lubricating oil pump of most of structure, but there are certain air inlet wind
Danger, because in some cases, it is extraneous if poor sealing between pump cover and cylinder body with the progress of machine oil pump work
Air can be entered in oil suction chamber by the oil groove of pump cover oil suction chamber side, lubricating oil pump suck be caused, to influence lubricating oil pump
It works normally.Currently, axis hole lubricating oil can directly be let out by axis hole gap after oil outlet introducing there are also a kind of draining mode
To outside pump cover, in this way, the end face of pump cover cannot be sealed, and for the lubricating oil pump of a part of structure, being cannot for this
(during installation, due to the requirement on cylinder body installation boundary, the outer end of axis hole is the state in sealing to part lubricating oil pump) realized,
Therefore such draining mode smaller scope of application, cannot widely promote the use of.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of lubricating oil pump that the lubricating oil convenient for axis leaks, the machines
Oil pump is when the lubricating oil for carrying out axis leaks, it is possible to prevente effectively from there are air inlet risks for oil inlet.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: it is a kind of outer convenient for the lubricating oil progress of axis
The lubricating oil pump let out, including the pump housing, pump cover and axis, offer axis hole on the pump housing and pump cover respectively, on the pump housing and pump cover
Oil suction chamber and oil outlet chamber are also offered, the pump cover is mounted on the pump housing, and the axis is mounted in the axis hole of the pump housing and pump cover,
The pump cover draws oil groove towards offering on the side of the pump housing from the axis hole that the oil outlet chamber of pump cover leads to pump cover, the pump cover
The drain pan for leading to the edge of pump cover from the axis hole of pump cover is offered on end face.
Further, the depth of the drain pan is 3-5mm.
Further, the drain pan includes the first drain pan, the second drain pan and third drain pan being sequentially communicated,
One end of first drain pan is connected to the axis hole of pump cover, and one end of the third drain pan is worn to the edge of pump cover, described
First drain pan and third drain pan are respectively the slot of strip structure, and second drain pan is the slot of sector structure.
Still further, the depth of second drain pan is greater than the depth of the first drain pan and third drain pan.
Preferably, ring bush is installed, the axis is passed through from ring bush, the annular in the axis hole of the pump cover
The end face of bushing is lower than the end face of pump cover.
Lubricating oil pump provided by the invention is introduced into lubricating oil into axis hole at work, by drawing oil groove, then passes through drain pan
Lubricating oil in axis hole is let out into oil sump, during this draining, lubricating oil does not pass through the oil suction chamber of pump cover, but logical
The drain pan crossed on pump cover returns in oil sump, can be in this way, will not enter in lubricating oil pump with air when lubricating oil draining
Effectively avoiding the oil inlet of lubricating oil pump, there are air inlet risks.Obviously, the axis hole lubricating oil draining of lubricating oil pump provided by the invention
The axis hole lubricating oil draining mode of mode and traditional lubricating oil pump is different, the present invention in the case where not changing other structures,
Oil inlet can effectively be prevented there are air inlet risks by opening drain pan in pump cover end face, both simply, at low cost, and can be pushed away extensively
It is wide to use.

Concrete condition understands the concrete meaning of the term.
As depicted in figs. 1 and 2, a kind of lubricating oil pump that the lubricating oil convenient for axis leaks, including the pump housing 1, pump cover 2 and axis
3, axis hole 4 is offered respectively on the pump housing 1 and pump cover 2, also offers oil suction chamber 5 and oil outlet chamber 6, pump cover on the pump housing 1 and pump cover 2
2 are mounted on the pump housing 1, and axis 3 passes perpendicularly through the axis hole 4 of the pump housing 1 and pump cover 2, are mounted on the pump housing 1 and pump cover 2,2 direction of pump cover
The axis hole 4 from the oil outlet chamber 6 of pump cover 2 towards pump cover 2 is offered on the side of the pump housing 1 draws oil groove 7, the end face (pump cover of pump cover 2
2 back to the side of the pump housing 1) on offer the drain pan 8 for leading to the edge of pump cover 2 from the axis hole 4 of pump cover 2.
The lubricating oil pump that above embodiment provides is introduced into lubricating oil into axis hole 4 by drawing oil groove 7, then passes through drain pan 8
Lubricating oil in axis hole 4 is let out into oil sump, during this draining, lubricating oil does not pass through the oil suction chamber 5 of pump cover 2, and
It is to be returned in oil sump by the drain pan 8 on pump cover 2, in this way, which when lubricating oil draining lubricating oil pump will not be entered with air
In, it is possible to prevente effectively from there are air inlet risks for the oil inlet of lubricating oil pump.
Further, the depth of drain pan 8 is 3-5mm.
The shape of drain pan 8 in present embodiment can there are many, in order to energy-saving material, mitigate the weight of pump cover 2, drop
Low cost, drain pan 8 can include the first drain pan 8a, the second drain pan 8b being sequentially communicated using such as flowering structure, drain pan 8
With third drain pan 8c, one end of the first drain pan 8a is connected to the axis hole 4 of pump cover 2, the other end of the first drain pan 8a and
