Description
Technical field
This utility model relates to a kind of oil pump end cap.
Background technology
Current existing motor pump, it is common that oil pump shaft is directly adaptive with motor shaft phase plug-in mounting by spline,
To carry out corresponding power output operation.But, although this kind of motor pump fit structure disclosure satisfy that substantially
Use need, but owing to the phenomenon of oil pump leakage of oil easily occurring under its long-time high load capacity duty.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome existing motor pump at long-time high load capacity
The deficiency of easy leakage of oil under duty, this utility model provides a kind of oil pump end cap.
This utility model solves its technical problem and be the technical scheme is that a kind of oil pump end cap, for electricity
Lubricating oil pump, including end cap body, the middle part of described end cap body has axis hole, before described end cap body has
End face and rear end face, described front end face coordinates installation with motor pump, described front end face offers annular close
Sealing groove and some bolts hole, described bolt hole is blind hole, and described bolt hole is uniform around described axis hole, described
Annular seal groove is between bolt hole and axis hole, and the cross section of described annular seal groove is swallow-tail form, described ring
In shape seal groove, sealing ring is installed；The periphery of each bolt hole offers annular mounting groove, described annular peace
Cork washer it is embedded with in tankage.
Having two symmetrically arranged mounting ears on described rear end face, described mounting ear has installing hole.
Described rear end face is provided with locating dowel, and described locating dowel is triangular prism shaped.
Described sealing ring is O shape rubber seal.
The beneficial effects of the utility model are, oil pump end cap of the present utility model, have offered ring in axis hole periphery
Shape seal groove, and sealing ring is installed in annular seal groove, sealing ring makes end cap seal against each other with motor pump；
Simultaneously as it is inconsistent to vibrate relation between end cap and motor pump, end cap easily and produces between motor pump
Life is vibrated and is occurred each other to loosen to cause leakage of oil, and this utility model offers annular peace in the periphery of bolt hole
Tankage, is embedded cork washer in mounting groove, cork washer can alleviate the vibration between end cap and motor pump,
Prevent from end cap and motor pump from producing to loosen, it is to avoid motor pump under long-time high load capacity duty due to
End cap cannot seal with motor pump and cause leakage of oil；Further, annular seal groove is swallow-tail form, permissible
Just sealing ring is arranged in annular seal groove when oil pump end cap produces, and owing to annular seal groove is dovetail
Shape, it is possible to prevent the sealing ring of the inside from dropping out, therefore, the sealing ring of oil pump end cap can produce with factory and carry,
When installing oil pump end cap of the present utility model without additionally mounted sealing ring, prevent installation personnel from forgetting when installing
Note is installed sealing ring and is made motor pump generation leakage of oil.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are showing of simplification
Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model
Relevant composition.
As shown in Figure 1, Figure 3, a kind of oil pump end cap of the present utility model, for motor pump, including end cap
Body, the middle part of described end cap body has axis hole 1, and described end cap body has front end face 2 and rear end face 3,
Described front end face 2 coordinates installation with motor pump, if offer on described front end face 2 annular seal groove 4 and
Bolt stem hole 5, described bolt hole 5 is blind hole, and described bolt hole 5 is uniform around described axis hole 1, described ring
Shape seal groove 4 between bolt hole 5 and axis hole 1, as in figure 2 it is shown, described annular seal groove 4 cut
Face is swallow-tail form, is provided with sealing ring (being not drawn in figure) in described annular seal groove 4, and described sealing ring is
O shape rubber seal.
The periphery of each bolt hole 5 offers annular mounting groove 6, is embedded with cork in described annular mounting groove 6
Packing ring (is not drawn in figure).
As it is shown on figure 3, have two symmetrically arranged mounting ears 7, described mounting ear 7 on described rear end face 3
There is installing hole 8.Being additionally provided with locating dowel 9 on described rear end face 3, as shown in Figure 4, described locating dowel 9 is
Triangular prism shaped.
Oil pump end cap of the present utility model, has offered annular seal groove 4 in axis hole 1 periphery, and in ring packing
Installing sealing ring in groove 4, sealing ring makes end cap seal against each other with motor pump；Simultaneously as end cap and electricity
Vibrating relation between lubricating oil pump inconsistent, end cap easily and produces vibration between motor pump and sends out each other
Raw loosening causes leakage of oil, and this utility model offers annular mounting groove 6 in the periphery of bolt hole 5, in mounting groove 6
Being embedded cork washer, cork washer can alleviate the vibration between end cap and motor pump, prevents end cap and electricity
Lubricating oil pump produces and loosens, it is to avoid motor pump cannot be with electricity due to end cap under long-time high load capacity duty
Lubricating oil pump seals and causes leakage of oil；Further, annular seal groove 4 is swallow-tail form, can be at oil pump end cap
Just sealing ring is arranged in annular seal groove 4 during production, and owing to annular seal groove 4 is swallow-tail form, energy
The sealing ring enough preventing the inside drops out, and therefore, the sealing ring of oil pump end cap can produce with factory and carry, in peace
Without additionally mounted sealing ring when filling oil pump end cap of the present utility model, prevent installation personnel from when installing, forgetting peace
Fill sealing ring and make motor pump generation leakage of oil.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant
Staff can carry out various change completely in the range of without departing from this utility model technological thought
And amendment.The content that the technical scope of this utility model is not limited in description, it is necessary to root
