Description
Technical field
The present invention relates to a kind of engine lubrication system component, in particular to a kind of vane type lubricating oil pump.
Background technique
Vane type lubricating oil pump is a kind of displacement-variable oil pump, it includes the pump housing, pump cover, transmission shaft, blade, rotor, change
Spring, variable sliding block are measured, the cavity for being used to install variable sliding block, rotor and variable spring and transmission shaft installation are equipped in the pump housing
Hole also is provided with transmission shaft mounting hole on pump cover.Variable sliding block is mounted in the cavity on the pump housing, and rotor is then mounted on variable sliding block
Rotor chamber in.Rotor is equipped with axis hole and for installing the mounting groove of blade, blade mounting groove uniformly respectively on rotor,
A blade is fitted in each blade mounting groove, blade can move radially in blade mounting groove.
It is end face oil inlet from rotor and variable sliding block that the structure of this vane type lubricating oil pump, which determines, when rotor and variable
The thickness of sliding block is too thick, in mesohigh region because the thickness of sliding block and revolving speed reason will lead to it is oil-filled discontented, so as to cause containing
Gas is excessive, keeps volumetric efficiency decline serious and generates cavitation erosion part of damage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vane type lubricating oil pump that can improve volumetric efficiency.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of blade that can improve volumetric efficiency
Formula lubricating oil pump, including the pump housing, pump cover, transmission shaft, rotor, blade, variable sliding block and variable spring, the pump housing are equipped with and are used for
The cavity of rotor, blade, variable sliding block and variable spring is accommodated, the rotor is fixed on transmission shaft, and the one of the transmission shaft
End is mounted in the axis hole of the pump housing, and the other end is mounted in the axis hole of pump cover, and the circumferential surface of the variable sliding block is equipped with a radial direction
Through-hole, the through-hole is located at oil inlet end.
Preferably, the through-hole is waist-shaped hole.
The beneficial effects of the present invention are: in above-mentioned technical proposal, since the circumferential surface of variable sliding block is equipped with the logical of a radial direction
Hole, and the through-hole is located at oil inlet end, it, not only can be from the end face oil inlet of rotor and variable sliding block, also in this way when rotor operates
It can enable oil liquid in time full of operating mesh regional from the through-hole oil inlet of variable sliding block circumferential surface, to be promoted in high-speed region
Volumetric efficiency improves cavitation erosion.
