Description

A kind of swinging blower fan with bent axle
Technical field
The present invention relates to a kind of swinging blower fan, more particularly to a kind of swinging blower fan with bent axle.
Background technology
Swinging blower fan is a kind of positive displacement blower fan, has the permanent torque gas mechanical characteristics of forced conveyance.Its is relative simultaneously Roots blower has higher volumetric efficiency, lower slip.Its operation principle is under the guiding of eccentric wheel, produces centrifugation Power(Or use spring)Drive slide plate to be close on cylinder wall to be rotated, change is constantly produced in cylinder body by slide plate and eccentric wheel The volume of change, and realize the acting to air.
The shortcomings that its is maximum is because slide plate produces violent friction with cylinder body, therefore seriously limits the line on slide plate top Speed.Cause the blower fan of the model both to have done in volume to be also impossible to be lifted on rotating speed greatly.So market-ripe Swinging blower fan, its flow is general all within 8m3/min, and body rotating speed is no more than 500RPM.
In order to overcome the shortcoming, there is one kind and slide plate is fixed with hinge axis, control between slide plate and cylinder body and exist necessarily Gap, the structure of frictionless motion is carried out in cylinder body with the dynamic slide plate of eccentric wheel rotating band.The structure solves swinging wind Machine because friction and caused linear velocity limits, rotating speed can be significantly improved, greatly reduce volume under equal flow, or The flow of several times can be achieved in equal volume.But in view of necessarily there is rotating shaft between the centre of gyration of hinge axis and eccentric wheel Interference.So core component of body:Hinge axis and eccentric wheel all use cantilever design.It is this design pressure, rotating speed compared with Cause eccentric wheel and hinge axis beat and vibration occur when high, influence design gaps, gap, which diminishes, causes friction or gap Change causes pressure to be lost greatly.And in order to maintain intensity, general hinge axis needs to use thicker diameter design, and eccentric wheel needs Wall thickness is thickeied, this yielding causes eccentric throw design severely limited, have impact on volumetric efficiency, also cause slide plate stress torque Shorten, slide plate strength demand becomes big.It is broken under high speed and eccentric runner causes centrifugal force to increase because wall thickness increases.Institute Often gravity is avoided to influence as far as possible using upright type of design with the structure, but upright type of design is unfavorable for internal lubrication again.This is also to be Any structure can not become matured product from drawing all the time and introduce to the market.
Accordingly, it is desirable to provide a kind of new technical scheme solves the above problems.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of rotating speed is fast, the swinging blower fan with bent axle of high flow capacity.
In order to solve the above technical problems, the present invention a kind of swinging blower fan with bent axle, it include cylinder body, transfer rod, partially Heart wheel, door assembly with hinge and glass in right hand and left slide plate and bent axle, the upper lateral part of cylinder body one are provided with air inlet, and the side lower part of cylinder body one is provided with air outlet, The eccentric wheel is installed in cylinder body, and the main shaft portion of the bent axle is concentrically mounted in cylinder body, the crank section of the bent axle It is then concentric with cylinder body, hinge wheel is provided with by bearing on the bent axle, bearing is linked inside and outside the hinge wheel respectively and door assembly with hinge and glass in right hand and left is slided Piece, the door assembly with hinge and glass in right hand and left slide plate are arranged on transfer rod, and the cylinder body both sides set shaft cylinder cap and closing cylinder cap respectively.
The eccentric wheel both ends are supported by the large and small bearing of eccentric wheel, and the crankshaft two end passes through the large and small bearing branch of bent axle Hold.
The present invention the swinging blower fan with bent axle, there is cylinder body, transfer rod, eccentric wheel, door assembly with hinge and glass in right hand and left slide plate and bent axle, when turn Son(Bent axle)During rotation, door assembly with hinge and glass in right hand and left slide plate is driven to be operated in cylinder body, because slide plate is using hinge axis as the centre of gyration, so rotation When turning, can control slide plate is cylindrical not contacted with inner chamber of cylinder block, occur without friction operate, the structure solve swinging blower fan because For friction, caused linear velocity limitation, can significantly improve rotating speed, volume is greatly reduced under equal flow, or equal The flow of several times can be achieved in volume.

Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should Embodiment is only used for explaining the present invention, does not form the restriction to protection scope of the present invention.
As shown in Figures 1 to 4, a kind of swinging blower fan with bent axle of the invention, it includes cylinder body 2, transfer rod 1, eccentric wheel 3rd, door assembly with hinge and glass in right hand and left slide plate 4 and bent axle 12, the upper lateral part of cylinder body 2 one are provided with air inlet 6, and the side lower part of cylinder body 2 one is provided with air outlet 7, eccentric Wheel 3 is installed in cylinder body 2, and the main shaft portion of bent axle 12 is concentrically mounted in cylinder body 2, the crank section of bent axle 12 then with cylinder body 2 With one heart, hinge wheel 5 is provided with by bearing on bent axle 12, bearing 15 and door assembly with hinge and glass in right hand and left slide plate 4, door assembly with hinge and glass in right hand and left is linked respectively inside and outside hinge wheel 5 Slide plate 4 is arranged on transfer rod 1, and the both sides of cylinder body 2 set shaft cylinder cap 14 and closing cylinder cap 13 respectively.
The both ends of eccentric wheel 3 are supported by the large and small bearing 10,8 of eccentric wheel, the both ends of bent axle 12 by the large and small bearing 11 of bent axle, 9 supportings.
Work as rotor(Bent axle)During rotation, drive door assembly with hinge and glass in right hand and left slide plate 4 to be operated in cylinder body 2, due to slide plate be using hinge axis as The centre of gyration, so during rotation, it can control slide plate cylindrical not with the lumen contact of cylinder body 2, occur operating without friction.
The swinging blower fan with bent axle of the present invention, slide plate is fixed with hinge axis, controls and has one between slide plate and cylinder body Fixed gap, the structure of frictionless motion is carried out in cylinder body with the dynamic slide plate of eccentric wheel rotating band.Eccentric wheel and hinge axis will not There is beat and vibration, do not interfere with design gaps, also do not interfere with lubrication.The structure solves swinging blower fan because friction And caused linear velocity limitation, rotating speed can be significantly improved, volume is greatly reduced under equal flow, or in equal volume The flow of several times can be achieved.
