Description
Technical field
The present invention relates to engine lubrication system, specifically a kind of blade pump rotor and a kind of noise can be reduced
Vane pump.
Background technique
Engine noise is the main source of automobile noise, in order to improve the comfort of automobile, it is necessary to which control appropriate is simultaneously
Reduce noise.Engine speed and pump speed are usually constant-speed ratio, so the order noise that lubricating oil pump is generated in rotation process
There are linear relationships, the specially a certain multiple of engine speed with engine speed.Order, that is, signal frequency corresponds to whirler
The frequency multiplication of tool rotational frequency.Wherein order, revolving speed, the relationship between frequency are as follows: order=frequency/revolving speed, order can be understood as
Change frequency of the signal within the period of one circle of rotating machinery rotation.
Currently, being the order noise problem for solving vane pump in industry, not equal part rotor is generallyd use, so that rotor rotates
After a week, there is not superimposed noise in the same position, reduce order noise.For example, Chinese invention patent
No. 2017209648358 disclose a kind of vane type lubricating oil pump (207438115 U of notification number CN), using the leaf of Unequal distance
Chip architecture design, significantly reduces the order noise of order feature and lubricating oil pump.
But a new problem can be brought using not equal part rotor, i.e., the geometric center of equal part rotor is not weighed with mass center
It closes, rotor is caused to there is an eccentricity during rotation, cause movement uneven, for a long time, necessarily affect product
Reliability.
Summary of the invention
Noise, which can be reduced, again the technical problem to be solved in the present invention is to provide one kind can guarantee the vane pump of moving equilibrium
Rotor, while a kind of vane pump that can reduce noise using above-mentioned rotor structure being also provided.
In order to solve the above-mentioned technical problem, the present invention is about the technical solution of vane pump: a kind of blade pump rotor, including
Axis hole, outer peripheral surface and two end faces, the outer peripheral surface of the rotor are equipped with multiple for installing the blade groove of blade, multiple blades
Slot is circumferentially distributed by unequal interval along rotor, and the either end facet of the rotor or two end faces are equipped with compensating groove,
The compensating groove is used to adjust the mass center of rotor, is overlapped the mass center of rotor with the geometric center of rotor.The rotor of this structure
Both it can be reduced pressure oscillation, reduce noise, and can guarantee the balance of rotor motion.
After establishing the inventive concept of compensating groove, long arc shape, kidney-shaped, triangle can be as the shape of compensating groove
The regular shapes such as shape, square, circle, prismatic or irregular shape.
As a preferred option, the outer peripheral surface for being located proximate to rotor of compensating groove
Wherein, the quantity of blade groove is N number of, N number of angle is formed between N number of blade groove, the angle between N number of angle is not mutually equal
Or only part angle is equal.
A kind of vane pump that can reduce noise provided by the invention, including the pump housing (1), pump cover (2), rotor, blade, change
It essentially consists in into point using blade pump rotor provided by the present invention.
Not equal part rotor using the above structure, can obtain it is following the utility model has the advantages that
1) pressure oscillation is advantageously reduced, noise is reduced；
2) it advantageously reduces and the abrasion of the pump housing, pump cover；
3) compensating groove is conducive to mitigate weight；
4) mass center that rotor is adjusted by compensating groove, is overlapped the mass center of rotor with the geometric center of rotor, thus can be true
The running balance for protecting not equal part rotor, to improve product reliability.
