Abstract
The utility model discloses a shaft-in-shaft centering rotorpump provided with sliding plates and aims to provide an improved structure of a vane pump. The rotor pump comprises a case, arotor, a crankshaft, the sliding plates, blades and the like, wherein a liquid is discharged from one end to the other end by the sliding plates during rotation of the rotor so as to play the role of the rotor pump. Due to limitation by the crankshaft (8), the sliding plates are prevented from being rubbed against the case under the inertia effect during rotation along with the rotor, the sliding plates are higher in revolving speed and lower in noise and can be made thicker and longer, the larger pressure and volume space can be obtained, the flow is large, the size is small, the efficiency is high, the application range is wide, and the rotor pump is applicable to an oil pump, a water pump, a motor, an air compressor, a vacuum pump, a driving paddle and the like.
Description
Technical field
The utility model relates to a kind of pump, is the improvement structure of vane pump.It can be used for oil pump, water pump, motor, air compressor, vacuum pump, driving oar etc.
Background technique
Since the nearly century, there is a kind of vane pump, be usually used in hydraulic transmission, it is made up of housing, rotor, blade etc., because blade is radial installation on rotor, causes the thickness of blade and extend to be all restricted, because the effect of inertial force, blade is to strengthen with the frictional force of housing with the increase of thickness, the corresponding sharp increase of noise, and shorten working life.Blade extrusion is subject to the restriction of rotor groove depth, so the volume space of vane pump is all very little, flow is little, volume is large, efficiency is low, and therefore it only limits to use in object oil hydraulic pump taking transmission so far, and other uses the occasion of pump just extremely rare taking flow as object.
Summary of the invention
The above-mentioned defect existing for prior art, the utility model aims to provide the axis in axis centering slide plate rotor pump that a kind of flow is large, volume is little, efficiency is high, noise is low.
In order to achieve the above object, the utility model has adopted following technological scheme: it comprises a bent axle in rotor, at least one or more slide plate cross mounting is on bent axle and to being through in the groove of rotor, slide plate can slide in groove, bent axle has limited the sliding scale of slide plate on groove by the effect of centring sleeve, one end of bent axle is by the bearings in rotor, the other end is by the bearings on clamping plate, tailing axle is contained on rotor, be contained in housing by the bearings on protecgulum and bonnet together with bent axle, one end of bent axle is fixed on bonnet, do not allow to rotate, when rotor rotates together with slide plate, slide plate top remains with housing some gaps.
Each slide plate divides two sections to be fixed on shuttle ring and to form a whole, blade is equipped with on the top of slide plate, when slide plate rotates with rotor, limit slide plate in epitrochanterian extrusion by the centring sleeve on bent axle, rotor and slide plate have been centered around respectively on two centers of circle and rotate.
Epitrochanterian internal thread coordinates and is fitted together with the outside thread on clamping plate, and the screw-internal thread fit on epitrochanterian outside thread and tailing axle is fitted together, and clamp screw is fitted together through the screw-internal thread fit of tailing axle and clamping plate, and rotor and tailing axle are fixed into an entirety.
Compared with the existing technology: the utility model is because adopted such scheme, change blade into slide plate to being through on rotor in epitrochanterian radial installation, the extrusion of slide plate extends greatly, adopt the method for Crankshaft Alignment to there is multiple effect: one, slide plate and housing can keep certain interval, have avoided frictional force and the wearing and tearing of slide plate and housing; Two, avoided causing that because the thickening of slide plate increases inertial force the shock of slide plate and housing aggravates, therefore slide plate can be thickeied arbitrarily lengthening; Three, rotor and slide plate noise and vibration in the time of high rotating speed reduces greatly, and rotating speed can be multiplied, and follows effect also can significantly improve, and this just provides precondition for the expansion of its using scope, such as high-speed motor, ships drive oar etc.; Four, allowing slide plate further thicken lengthening in the situation that, can obtain that pressure is high, flow is large, volume is little, efficiency is high.
