(1) the power transmission between them is still realized in the case of substantially motionless along axis.
Further, the lubricating oil pump also includes inertia actuating mechanism.The inertia actuating mechanism can include mass 11, lead
To plate 10 and swing arm 12.The inertia actuating mechanism is arranged on the outside of pump cover 17 and can be by the servo axis 11 (2) on the whole
Driving is rotated.Specifically, the mass 11 has the body and ear body of flat, and the body and the ear body are basic
Vertically.The mass 11 also has guide groove, and mass 11 is movably arranged on the guide plate 10 using its guide groove.Quality
Block 11 is pressed close to guide plate 10 and arranged, only allows to guide surface of the mass 11 along the guide plate 10 in other words in guide groove

The servo axis 1 (2) and the mass 11 are rotatablely connected.
Specifically, when servo axis 1 (2) driving guide plate 10 rotates, the guide plate 10 will drive the mass 11 to enter
Row rotates.Will be away from servo axis 1 (2) in centrifugal force caused by rotation, mass 11 using the mass 11
Direction is moved, so as to drive swing arm 12 to pivot.The pivot of now swing arm 12 will increase its axial component along servo axis 1 (2)
Length, so as to force the servo axis 1 (2) along its axis away from pump cover 17 in other words away from the drive shaft 1 (1)
Move in direction.The internal rotor 15 so can be then driven to be moved along the axis relative to the outer rotor 14, so as to change
Along the length of action L of the axis between the internal rotor 15 and the outer rotor 14.
Pump cover 17 has oil inlet, oil-out and oil duct, and wherein oil inlet is adjacent to low pressure oil area, and oil-out is adjacent to hydraulic oil
Area.Servo axis 1 (2) drive internal rotor 15 to be rotated relative to outer rotor 14, machine oil is entered high pressure oil area by low pressure oil area 20
21.Meanwhile the machine oil in high pressure oil area is entered the push pedal chamber on the right side of push pedal 16 by oil duct, formed to push pedal 6 to the left
Thrust.Under the thrust, push pedal 6 closes internal rotor 15 and the thrust for applying this in other words to the left is transmitted to internal rotor 15.Together
When, previously described inertia actuating mechanism can also produce centrifugal force at this moment, and by swing arm 12 by the centrifugal force convert to
The thrust to the right of moving axis 1 (2).Because internal rotor 15 is fixedly connected with servo axis 1 (2), therefore, mechanism pump is at work, interior
Rotor 15 and servo axis 1 (2) on the whole will by the thrust to the left from push pedal 16 and from inertia actuating mechanism to
Right thrust.
When lubricating oil pump is started working, the rotating speed of machine oil pump shaft 1 is started from scratch gradual increase.In low-speed stage, due to turning
Speed is relatively low, therefore centrifugal force caused by mass 11 is not enough to overcome the thrust of the offer of push pedal 16, and push pedal 16 promotes interior turn
Son 15 is attached on the bottom wall of pump case 13.Now internal rotor 15 and the length of action of outer rotor 14 are most long, and internal rotor 15, outer rotor 14
And push pedal 16 will be isolated between low pressure oil area and high pressure oil area, without connecting between low pressure oil area and high pressure oil area.It should be noted
, " no connection " here means that machine oil is only capable of by the pump oil mechanism that internal rotor 15 and outer rotor 14 are formed from low pressure oil
Area is pumped to high pressure oil area.Now, the pumping efficiency highest of whole lubricating oil pump, ensure that each parts are to machine oil during low-speed running
Demand.
Now, there is the first length of action between the internal rotor 15 and the outer rotor 14.In the first length of action,
The internal rotor 15 and the outer rotor 14 be positioned to by the high pressure oil area and the low pressure oil separate from.Now pumping efficiency
It is maximum.
Further increase with the rotating speed of machine oil pump shaft 1, centrifugal force can also increase therewith caused by inertia actuating mechanism, come
It is more than the thrust to the left from push pedal 16 from the thrust to the right of inertia actuating mechanism.Can thus force the servo axis 1 (2) and
Internal rotor 15 moves right.Now, have between internal rotor 15 and outer rotor 14 and nibbled less than the second of first length of action
Close length.In the second length of action, the internal rotor 15 and the outer rotor 14 are located so that the high pressure oil area and institute
The connection of low pressure oil area part is stated, " part connects " here means also to tie up between the high pressure oil area and the low pressure oil area
Hold and cause the internal rotor 15 and the outer rotor 14 to provide the pressure difference needed for the pumping efficiency more than zero.
Lubricating oil pump provided by the invention pumping efficiency in machine oil pump shaft low-speed running state is higher, can provide enough machines
Oil mass lubricates for parts.When machine oil pump shaft runs at high speed state, pumping efficiency step-down, but the flow of machine oil does not have with pressure
There is step-down.This achieve high pumping efficiency during machine oil pump shaft low-speed running, without pressure release when running at high speed, meet engine lubrication
The purpose of demand.
Above disclosure is only preferred embodiment of present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to the claims in the present invention, still belong to the scope that the present invention is covered.
