Description
Technical field
The present invention relates to a kind of enhanced self-lubricating lubricating oil pump.
Background technology
As internal combustion engine is in multi-field extensive use, speed-raising, slewing range have it is larger widen, i.e. performance and quality
It is greatly improved.Therefore, Modern Internal-Combustion Engine proposes higher requirement to the performance of lubricating system critical piece lubricating oil pump,
The middle-size and small-size internal combustion engine in China generally uses internal messing cycloidal rotor oil pump at present.In long-term production practices, it has been found that use
In the rotor-type oil pump of lubricating system of IC engine, certain positions are since there are lack of lubrication, quick abrasion causes oil pump pump oil to be imitated
Rate attenuation is fast, and especially big flow impeller pump is more prominent, affects the service life of oil pump.
The performance and Acceptable life of oil pump are how effectively improved, becomes the problem of industry gives more sustained attention.
Invention content
To solve the above problems, present invention firstly provides the first technical solution, specially a kind of enhanced self-lubricating machine oil
Pump, including the pump housing and pump cover, is provided with the first oil sucting cavity and the first oil outlet chamber on the pump housing；The second suction is provided on pump cover
Oil pocket and the second oil outlet chamber and fuel feed hole and oil outlet, wherein fuel feed hole run through the second oil sucting cavity, and oil outlet goes out through second
Oil pocket；After the pump housing and pump cover overlap, first oil sucting cavity and the second oil sucting cavity are opposite, and the first oil outlet chamber and second goes out
Oil pocket is opposite.
It is changed to be separately positioned in upper and lower ends face, and position corresponds to and coincide, such design solves conventional pump presence
Several respects deficiency factor.Conventional pump is generally inhaled using single end face setting, pumping cavity, in theory：In operation, oil suction
Cavity space is being continuously increased, and intracavitary generates negative pressure, realizes oil suction, action direction is towards oil suction direction, and fuel-displaced cavity space is not
Disconnected to reduce, intracavitary generates positive pressure, forms oil pressure space, in this way, the rotor of reaction force and the pump housing, the faying face of pump cover are born,
There are two opposite positions, rotor is made to be run in the state of being in discontinuity equalization, affects performance and the use of oil pump
Service life.The both ends of the surface of rotor and pump cover, pump cover are all provided with being set to the equal suction in space, pumping cavity in corresponding position by we now,
Solve rotor in operation, the unbalanced problem of active force, meanwhile, make oil Pump rotor both ends of the surface and the pump housing, pump cover friction equal
Deng, and sufficient lubrication is obtained, and the active force that suction, pumping cavity generate is in equilibrium state.The overall structure of oil pump is more reasonable,
Especially big flow oil pump due to needing the space of larger suction, pumping cavity, is often limited by area, by oil pocket design compared with
It is deep, easily occur oil suction deficiency in operation, a problem that being emptied, the design of double oil pockets up and down substantially improves the operation item of oil pump
Part makes oil pump performance be greatly improved.
Further, outer rotor is further included, the outer rotor includes outer rotor body, internal rotor is provided in outer rotor block
Chamber is provided with the groove of annular in the middle part of the outer wall of outer rotor block, oilhole is offered in groove, the oilhole is through outer
The outer wall of rotor block, one end of the oilhole are located at the heel of internal rotor chamber.
In the design, in order to ensure that it is larger that flow often designs the height of rotor and diameter dimension, in this way, certainly will make
Increase into outer rotor and pump housing hole contact surface, generate larger frictional resistance, and bring the unfavorable condition of lack of lubrication, be not suitable with
It runs at high speed.After groove and oilhole that annular is set on the outer wall of outer rotor block, when rotor each rotation, aperture is in pressure oil
During chamber, lubricating cavity fuel feeding is given through aperture, the lower sealing surface infiltration upwards of the oil in lubricating cavity, so as to make outer rotor periphery and pump housing knot
Conjunction face is in the protection of sufficient oil film and operates, and aperture is only little on the influence of oil pump pump oil amount for the oil mass of infiltration, transports oil pump
Capable rubbing surface obtains appropriate lubricating condition, and reduces rubbing surface, reduces frictional resistance, runs at high speed creation for oil pump
Condition.
Further, 25-40%, depth 0.3-0.6mm of the width of the groove for the height of outer rotor body.Further
Ground is preferred, the width of the groove for the height of outer rotor body 1/3, depth 0.5mm.Further, the diameter of the oilhole
Preferably 2mm.
Further, seal groove is provided on the pump housing.The seal groove is for installing sealing strip, to ensure the sealing of lubricating oil pump
Property.
Secondly, the application also provides the second technical solution, specially a kind of enhanced self-lubricating lubricating oil pump, including the pump housing
And pump cover, the first oil sucting cavity and the first oil outlet chamber and fuel feed hole and oil outlet are provided on the pump housing, wherein fuel feed hole runs through
First oil sucting cavity, oil outlet run through the first oil outlet chamber；The second oil sucting cavity and the second oil outlet chamber are provided on pump cover；When the pump
After body and pump cover overlapping, first oil sucting cavity and the second oil sucting cavity are opposite, and the first oil outlet chamber and the second oil outlet chamber are opposite.
Further, the second technical solution further includes outer rotor, and the outer rotor includes outer rotor body, set in outer rotor block
Internal rotor chamber is equipped with, the middle part of the outer wall of outer rotor block is provided with the groove of annular, oilhole is offered in groove, it is described
Oilhole runs through the outer wall of outer rotor body, and one end of the oilhole is located at the heel of internal rotor chamber.
Further, 25-40% of the width of groove described in the second technical solution for the height of outer rotor body, depth are
0.3-0.6mm。
Second technical solution is differed only in the first technical solution, and fuel feed hole and oil outlet are arranged on the pump housing,
Effect is identical with the first technical solution.
