For the problems referred to above, the patent document of Publication No. CN203584904U discloses a kind of vane pump, its technical scheme is: include the pump housing, the described pump housing is provided with oil inlet passage and oil discharge passage, rotating shaft it is provided with vertically on the pump housing, it is set with rotor in described rotating shaft, several blades it are uniformly provided with on described rotor, rotor periphery has stator, described stator be provided with respectively with oil inlet passage, the suction inlet of oil discharge passage connection and outlet, stator inner wall be provided with wearing layer, described wearing layer is alloy coating layer, described blade end is provided with the paddle of circular shape, described paddle end is provided with sealing gasket, described sealing gasket and wearing layer gap-contact.
In technique scheme, by setting wearing layer on stator inner wall, realize reducing the abrasion of stator inner wall.But, owing to sliding friction not being changed into rolling friction so that stator inner wall still weares and teares comparatively fast.
Utility model content
This utility model is intended to provide a kind of roller type vane pump, so that the sliding friction of blade tip and stator inner wall circumference is changed into rolling friction to reduce the abrasion of stator inner wall circumference.
Roller type vane pump in this programme, base case is: includes the pump housing and is coaxially installed in the stator in the pump housing and rotor, and stator and rotor eccentricity are arranged, and the pump housing is provided with oil inlet passage and oil discharge passage, the two ends of stator are provided with oil distribution casing, the periphery of rotor is uniformly provided with blade, and rotor is uniformly provided with some fixing holes, is provided with spring in fixing hole, spring is provided with blade, the top of blade is provided with two projections, protruding connection has the axis of rolling, the axis of rolling to be provided with running roller.
Operation principle and beneficial effect: during work, rotor rotates in stator, owing to stator and rotor eccentricity are arranged so that the blade on rotor compresses stator inner wall under the pressure of centrifugal action and spring.Unlike the prior art, owing to the top of blade is provided with two projections, in projection, connection has the axis of rolling, the axis of rolling to be provided with running roller.Make blade tip be become rolling friction with contacting of stator inner wall from sliding friction, reduce the blade abrasion to stator inner wall.Owing to being provided with two projections, make blade that the pressure of the axis of rolling can be uniformly distributed, it is to avoid running roller is inconsistent to the pressure of stator inner wall, and the leakage of oil that causes owing to pressure is inconsistent or the situation such as inconsistent of wearing and tearing.In sum, this programme provides the benefit that and reduces the blade abrasion to stator inner wall by arranging running roller on the top of blade.
Scheme 2, as the improvement to base case, blade has angle with the radial direction of rotor.Advantage is, blade, in addition to stress diametrically, the most also wants the pressure of liquid body, arranges angle and blade can provide the support force of circumference.
Scheme 3, as the improvement to scheme 2, the direction that blade is contrary with the angle of rotor radial deflection rotor rotation direction.Advantage is, the part making blade be positioned at through hole can directly provide support force, it is to avoid blade bends.
Scheme 4, as the improvement to base case, projection is uniformly arranged vertically on the top of blade.Advantage is, further such that projection is uniform to the pressure of the axis of rolling, and then makes running roller uniform to the pressure of stator inner wall.
Scheme 5, as the improvement to base case, stator inner wall is circumferentially with wearing layer.Advantage is, improves the wearability of stator inner wall.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model roller type vane pump embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: the pump housing 10, stator 20, rotor 30, spring 31, blade 32, the axis of rolling 33, running roller 34.
Embodiment
As shown in Figure 1, roller type vane pump, scheme is: include the pump housing 10 and the stator 20 being coaxially installed in the pump housing 10 and rotor 30, stator 20 and rotor 30 eccentric setting, the pump housing 10 is provided with oil inlet passage and oil discharge passage, the two ends of stator 20 are provided with oil distribution casing, the periphery of rotor 30 is uniformly provided with blade 32, some fixing holes it are uniformly provided with on rotor 30, being provided with spring 21 in fixing hole, spring is provided with blade 32, and the top of blade 32 is provided with two projections, there is the axis of rolling 33 protruding connection, and the axis of rolling is hinged with running roller 34.
It addition, in the present embodiment, blade 32 has angle with the radial direction of rotor 30.Advantage is, blade 32, in addition to stress diametrically, the most also wants the pressure of liquid body, arranges angle and blade 32 can provide the support force of circumference.The direction that blade 32 is contrary with rotor 30 angle deflection rotor 30 rotation direction radially.Advantage is, the part making blade 32 be positioned at through hole can directly provide support force, it is to avoid blade 32 bends.Projection is uniformly arranged vertically on the top of blade 32.Advantage is, further such that projection is uniform to the pressure of the axis of rolling 33, and then makes running roller 34 uniform to the pressure of stator 20 inwall.Stator 20 inwall is circumferentially with wearing layer.Advantage is, improves the wearability of stator 20 inwall.
During work, rotor 30 rotates in stator 20, due to stator 20 and rotor 30 eccentric setting so that the blade 32 on rotor 30 compresses stator 20 inwall under the pressure of centrifugal action and spring 31.Unlike the prior art, owing to the top of blade 32 is provided with two projections, in projection, connection has the axis of rolling 33, the axis of rolling 33 to be provided with running roller 34.Make blade 32 top be become rolling friction with contacting of stator 20 inwall from sliding friction, reduce the blade 32 abrasion to stator 20 inwall.Owing to being provided with two projections, make blade 32 that the pressure of the axis of rolling 33 can be uniformly distributed, it is to avoid running roller 34 is inconsistent to the pressure of stator 20 inwall, and the leakage of oil that causes owing to pressure is inconsistent or the situation such as inconsistent of wearing and tearing.In sum, the present embodiment is to reduce the blade 32 abrasion to stator 20 inwall by arranging running roller 34 on the top of blade 32.
