Description
Technical field
The structure-design technique field of vane pump is the utility model is related to, more specifically to a kind of rolling friction type
Vane pump.
Background technology
Vane pump belongs to hydraulic pump, is that a kind of rotated by rotor makes swept volume of a single chamber space change reach conveying liquid
Hydraulic pump.Traditional blades pump is mainly made up of rotor, stator, blade, power transmission shaft and former and later two valve plates.Stator has interior
Chamber, single acting vane pump bore of stator bus are circle, and rotor is fixedly installed in power transmission shaft and eccentric setting is in bore of stator；Double cropping
It is the non-circular curve that four arcses are equipped with that four sections of easement curves are formed, rotor axis and stator with the bore of stator bus of vane pump
Center line overlaps.In rotor rotation process, blade tip contacts with stator inner surface all the time so that and blade and stator wear are big,
Easily shorten vane pump whole service life.For problem above, exploitation is a kind of reasonable in design, and convenient and practical rolling rubs
Erasing vane pump is those skilled in the art's technical problems to be solved.
Utility model content
The technical problems to be solved in the utility model is：To overcome the technical problem mentioned in above-mentioned background technology, now carry
For a kind of rolling friction type vane pump reasonable in design, convenient and practical.
Technical scheme is used by the utility model solves its technical problem：A kind of rolling friction type vane pump, the leaf
Piece pump includes：Pump case, the filter vat being arranged in pump case, the support bar being arranged between inside pump casing and filter vat, it is arranged on
Rotor in filter vat, 4-8 arc impeller is symmetrically arranged with rotor, the arc-shaped leaf wheel end includes：3-5 ball and
The groove matched with ball；Wearing layer is coated with the inside of the filter vat, is set respectively in the both sides that support bar separates on filter vat
It is equipped with left filter bores and right filter bores.
Further, the support bar includes being fixedly connected between inside pump casing and filter vat and symmetrically arranged upper support
Bar and lower support bar；Inlet and liquid outlet, the right side that inlet separates with support bar, lower support bar are provided with the pump case
Side connects, and the left side that liquid outlet separates with support bar, lower support bar connects, and right filter bores aperture is less than left filter bores aperture；
The groove ends wire length is less than ball diameter, and depth of groove is more than ball bearing radius.
Beneficial effect：Compared with prior art, the structure design of rolling friction type vane pump of the present utility model is more closed
Reason, the setting of filter vat can effectively reduce solid impurity into the pump housing or the probability of the damage pump housing, the setting of wearing layer and ball
Vane pump service life can be effectively improved, the setting of arc impeller may be such that the fluid self-assembling formation vortex into the pump housing, resistance
It is smaller, convenient and practical, suitable further genralrlization application.
