Abstract
The present invention provides a kind of lubricating oil pump for being avoided that inordinate wear, one end including the pump housing, pump cover, shaft, the shaft is mounted in the axis hole of the pump housing, the other end is mounted in the axis hole of pump cover, the middle part of the shaft is equipped with rotor or gear, the medial surface of the pump housing and pump cover is equipped with oil-way, one end of the oil-way leads to the axis hole of the pump housing or pump cover and extends to shaft hole inner wall, makes to form a chip pocket on shaft hole inner wall.The axis hole of the pump housing or pump cover is led to due to one end of oil-way and is extended to shaft hole inner wall, make to form a chip pocket on shaft hole inner wall, oil liquid can not only be allowed preferably to lubricate axis hole and shaft by chip pocket in this way, and chip pocket can also be retained the particulate matter in oil liquid, gap location spin friction of the particulate matter always in shaft and axis hole is avoided, the inordinate wear for avoiding shaft and shaft hole inner wall therefore generating.
Description
Technical field
The present invention relates to a kind of engine lubrication system component, in particular to a kind of lubricating 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, but due to inevitably there is granule foreign in machine oil, because
This, while providing lubrication to axis hole and shaft, the granule foreign in oil liquid also will necessarily enter together axis hole and turn machine oil
The gap of axis.When shaft high speed rotation, the granule foreign in oil liquid can rotate in shaft and the close gap of axis hole,
It necessarily will affect the leakproofness between axis hole and shaft for a long time to generate inordinate wear to shaft hole inner wall and shaft.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lubricating oil pump for being avoided that inordinate wear.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of machine oil for being avoided that inordinate wear
Pump, one end including the pump housing, pump cover, shaft, the shaft are mounted in the axis hole of the pump housing, and the other end is mounted on the axis hole of pump cover
In, the middle part of the shaft is equipped with rotor or gear, and the medial surface of the pump housing and pump cover is equipped with oil-way, the lubrication
One end of oil groove leads to the axis hole of the pump housing or pump cover and extends to shaft hole inner wall, makes to form an appearance bits on shaft hole inner wall
Slot.
Preferably, the chip pocket is axially disposed on the shaft hole inner wall, and the length of the chip pocket is less than the axis
The length in hole.
Preferably, the lubricating oil pump is gear type oil pump.
The beneficial effects of the present invention are: since one end of oil-way leads to the axis hole of the pump housing or pump cover and to axis hole
Inner wall extends, and makes to form a chip pocket on shaft hole inner wall, oil liquid can not only be allowed preferably to lubricate axis by chip pocket in this way
Hole and shaft, and chip pocket can also be retained the particulate matter in oil liquid, avoid particulate matter always in shaft and axis hole
Gap location spin friction, avoid therefore inordinate wear that shaft and shaft hole inner wall generate.

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 3, the preferred embodiment of the present invention is: a kind of lubricating oil pump being avoided that inordinate wear, including the pump housing
1, pump cover 2, shaft 3, the shaft 3 one end be mounted in the axis hole of the pump housing 1, the other end is mounted in the axis hole of pump cover 2, institute
The middle part of shaft 3 is stated equipped with rotor or gear 4, the medial surface of the pump housing 1 and pump cover 2 is equipped with oil-way 5, the lubrication
One end of oil groove 5 leads to the axis hole of the pump housing 1 or pump cover 2 and extends to shaft hole inner wall, makes to form an appearance on shaft hole inner wall
Consider slot 6 to be worth doing, the chip pocket 6 is axially disposed on the shaft hole inner wall, and the length of the chip pocket 6 is less than the length of the axis hole
Degree.
As shown in Figure 1, the lubricating oil pump in the present embodiment is gear type oil pump.
The working principle and beneficial effect of the present embodiment is: since one end of oil-way 5 leads to the pump housing 1 or pump cover
2 axis hole and to shaft hole inner wall extend, make on shaft hole inner wall formed a chip pocket 6, oil liquid can not only be allowed to pass through appearance in this way
Bits slot 6 preferably lubricates axis hole and shaft 3, and chip pocket 6 can also be retained the particulate matter in oil liquid, avoid particle
Object is always in the gap location spin friction of shaft 3 and axis hole, the inordinate wear for avoiding shaft 3 and shaft hole inner wall therefore generating.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart from the technical program design under the premise of it is any obviously replace it is within the scope of the present invention.
In order to allow those of ordinary skill in the art more easily to understand the improvements of the present invention compared with the existing technology, this
Some attached drawings of invention and description have been simplified, and for the sake of clarity, present specification is omitted some other members
Element, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the contents of the present invention.
