Portion 122 is evenly distributed in the edge of end.
Second depressed part 121 is specifically as follows the depressed part of bar shaped second.It is appreciated that the second depressed part 121 can also it
Second depressed part 121 of his shape, such as cross second depressed part, the concrete shape of the second depressed part 121 should not be understood
To be to limitation of the present utility model.
It is appreciated that the pump core 120 can also be the pump core 120 of other shapes, for example, round table-like pump core, the pump core
It is to limitation of the present utility model that 120 concrete shape, which should not be construed,.
Fig. 3 is referred to, flexible fastening piece 110 includes protuberance 111 and connecting portion 112.Protuberance 111 can stretch to
In second depressed part 121, after protuberance 111 stretches into second depressed part 121 so that pump core 120 and flexible fastening piece 110
The relative slip in the axial direction of pump core 120 can occur, and the relative rotation in the circumference of pump core 120 can not occur.
112 specific quantity of connecting portion is two, and each both ends with protuberance 111 in two connecting portions 112 are connected,
Connecting portion 112 is used for the pump core 120 fixed where the second depressed part 121 that protuberance 111 and then fixed protuberance 111 stretch into.
Flexible fastening piece 110 is specifically as follows flexibly positioned steel wire, and flexibly positioned steel wire can be formed convex by bending
Go out portion 111 and connecting portion 112.Protuberance 111 is specifically as follows the shape of falling U structure, and inverted U-shaped stretches into the second depression of bar shaped
In portion 121, so as to avoid the movement of pump core 120 in the circumferential.
Details include cylindrical portion 131 and choke 132 referring to Fig. 1, oil pump overcoat 130, and choke 132 is specifically as follows
Round-like structure, and one end being relatively large in diameter of choke 132 is fixedly connected with one end of cylindrical portion 131, the axle of cylindrical portion 131
The axis of line and choke 132 coincides.Pump core 120 is arranged in oil pump overcoat 130.Pump core 120 is provided with the first depressed part
122 one end is stretched out from the choke 132.Oil pump overcoat 130 can rotate relative to pump core 120.Pump core 120 can have
First depressed part 122, and matched by the choke 132 of the first depressed part 122 and oil pump overcoat 130, pump core 120 also may be used
With including the angle of inclination identical round platform portion (not shown) with choke 132.Pump core 120 and the necking of oil pump overcoat 130
It is to limitation of the present utility model that the concrete structure at the position being engaged in portion 132, which should not be construed,.
Fig. 4 is referred to, the less end of diameter of low speed bent axle 150 connects with the less one end of the diameter of oil pump overcoat 130
Connect, and low speed bent axle 150 can drive the rotation of the oil pump overcoat 130 by rotating.It bears the power that connecting rod transmits,
And the power by the way that connecting rod is transmitted is changed into torque, is exported by bent axle and drive oil pump overcoat 130 to rotate.
The operation principle of necking oil pump that the utility model embodiment provides is：
Low speed bent axle 150 bears the power that connecting rod transmits, and is transformed into torque, exports and drives by low speed bent axle 150
Dynamic oil pump overcoat 130 rotates.Because the protuberance 111 of flexible fastening piece 110 is engaged with the second depressed part 121 of pump core 120,
So that pump core 120 is relatively fixed relative to flexible fastening piece 110 in the circumference of pump core 120, pump core 120 can be relative to elasticity
Fixture 110 moves in the axial direction.
Oil pump overcoat 130 is rotated, and pump core 120 and flexible fastening piece 110 are relatively fixed in the circumference of pump core 120, because
This oil pump overcoat 130 rotates relative to pump core 120.Because the outer surface of pump core 120 is provided with helicla flute 140, therefore lubricating oil exists
The side of oil pump overcoat 130 and the close flexible fastening piece 110 of pump core 120, the spiral set along the outer surface of pump core 120
Groove 140 is constantly by (upward) promotion in the direction away from the first depressed part 122, now, anti-work of the pump core 120 by lubricating oil
Firmly, drive flexible fastening piece 110 together (downward) mobile away from the direction of low speed bent axle 150.
When the rotating speed of low speed bent axle 150 is very fast, low speed bent axle 150 drives oil pump overcoat 130 to rotate, because pump core 120 exists
It is relatively fixed in circumference, so that oil pump overcoat 130 is also rotated with faster rotating speed relative to pump core 120.Therefore, lubricating oil
In the side of oil pump overcoat 130 and the close flexible fastening piece 110 of pump core 120, along helicla flute 140 by constantly towards close to low
The amount that the direction of fast bent axle 150 promotes is also more.When lubricating oil impacts the inwall of oil pump overcoat 130, equally can also produce compared with
The active force of big opposite direction, and the active force acts on pump core 120 so that contracting of the pump core 120 towards close oil pump overcoat 130
Oral area 132 direction movement, between pump core 120 and choke 132 be smaller than the rotating speed of low speed bent axle 150 it is slower when pump core
Spacing between 120 and choke 132.
Because the spacing between pump core 120 and choke 132 diminishes, so as to reduce the intake of oil, due to leading to for oil
Enter the reduction of amount, reduce pump oil effect during oil pump 130 high rotating speed of overcoat, avoid appearance and the oil extraction phenomenon of a large amount of mists
Produce.
The necking oil pump that the utility model embodiment provides can cause pump core 120 when the rotating speed of low speed bent axle 150 is very fast
Spacing between the choke 132 of oil pump overcoat 130 diminishes, so as to reduce the intake of oil, due to oily intake
Reduce, reduce pump oil effect during oil pump 130 high rotating speed of overcoat, avoid the appearance of a large amount of mists and the generation of oil extraction phenomenon.
It is appreciated that helicla flute 140 can be arranged on the outer surface of pump core 120, oil pump overcoat 130 can also be arranged on
Medial surface, it is to limitation of the present utility model that the specific set location of helicla flute 140, which should not be construed,.
The utility model embodiment additionally provides pump oil machine, and pump oil machine includes necking oil pump described above.
One end of the remote protuberance 111 of the connecting portion 112 of flexible fastening piece 110 can be fixed with the bottom of the pump oil machine
Connection.Flexible fastening piece 110 is fixedly connected with bottom, and fixed effect can be preferably played to pump core 120.
The utility model embodiment provide necking oil pump and pump oil machine include flexible fastening piece 110, pump core 120 and
Oil pump overcoat 130.Wherein, oil pump overcoat 130 includes cylindrical portion 131 and choke 132, cylindrical portion 131 and choke 132
Axis overlap, cylindrical portion 131 is fixedly connected with choke 132, and the diameter of choke 132 is less than or equal to cylindrical portion 131
Diameter.Pump core 120 is arranged in oil pump overcoat 130, and oil pump overcoat 130 can rotate relative to pump core 120, pump core 120 it is remote
One end from oil pump overcoat 130 is detachably connected with flexible fastening piece 110, and flexible fastening piece 110 exists for limiting pump core 120
Circumferential movement.When oil pump overcoat 130 rotates, because pump core 120 is relatively fixed in the circumferential, therefore oil pump overcoat 130 is relative
Rotated in pump core 120, so as to drive lubricating oil to move up.When the rotating speed of oil pump overcoat 130 accelerates, lubricating oil is continuous
Opposite motive force can be produced to pump core 120 while taking out upwards so that the spacing between pump core 120 and choke 132 reduces,
So as to reduce the intake of oil, due to the reduction of the intake of oil, pump oil effect during oil pump 130 high rotating speed of overcoat is reduced
Fruit, avoid the appearance of a large amount of mists and the generation of oil extraction phenomenon.
