Description
Technical field
The present invention relates to a kind of rotary type blower fan, particularly relate to a kind of rotary type blower fan with bent axle.
Background technique
Rotary type blower fan is a kind of positive displacement blower fan, has the permanent torque gas mechanical characteristics of forced conveyance.Its relative roots blower has higher volumetric efficiency, lower leak-down rate simultaneously.Its working principle is under eccentric guiding, produces centrifugal force (or with spring) and drives slide plate to be close on cylinder wall to rotate, the volume constantly changed in cylinder body by slide plate and eccentric wheel, and the acting of realization to air.
Its maximum shortcoming is because slide plate and cylinder body produce violent friction, therefore seriously limit the linear velocity on slide plate top.Cause the blower fan of this model both can not do on volume also can not promote on rotating speed greatly.So the rotary type blower fan of market-ripe, its flow is general all within 8m3/min, and body rotating speed is no more than 500RPM.
In order to overcome this shortcoming, occurring that one fixes slide plate with hinge axis, having controlled to there is certain interval between slide plate and cylinder body, rotarily driving with eccentric wheel the structure that slide plate carries out frictionless motion in cylinder body.The linear velocity that this structure solves rotary type blower fan and produces because of friction limits, and can significantly improve rotating speed, greatly reduce volume under equal flow, or can realize the flow of several times in equal volume.But, in view of occurring between hinge axis and the gyration center of eccentric wheel that rotating shaft is interfered.So the core component of body: hinge axis and eccentric wheel all adopt cantilever design.This design causes eccentric wheel and hinge axis to occur beat and vibration at pressure, rotating speed time higher, affect design gaps, and gap smaller causes friction or gap to become and causes pressure loss greatly.And in order to maintain intensity, general hinge axis needs to adopt thicker diameter design, eccentric wheel needs to thicken wall thickness, this yielding causes throw of eccentric design to be subject to strict restriction, have impact on volumetric efficiency, also cause the stressed moment of slide plate to shorten, slide plate strength demand becomes large.And eccentric runner causes centrifugal force to strengthen because wall thickness increases, lower easily broken at a high speed.So this structure often adopts upright type of design to avoid gravity effect as far as possible, but upright type of design is unfavorable for internal lubrication again.Also to be why this structure cannot become matured product from drawing all the time introduce to the market for this.
Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of rotating speed is fast, the rotary type blower fan of the band bent axle of high flow capacity.
For solving the problems of the technologies described above, a kind of rotary type blower fan with bent axle of the present invention, it comprises cylinder body, transfer rod, eccentric wheel, door assembly with hinge and glass in right hand and left slide plate and bent axle, described cylinder body one upper lateral part has intake grill, described cylinder body one side lower part has exhaust outlet, described eccentric wheel is installed in cylinder body, the main shaft portion of described bent axle is installed in cylinder body with one heart, the crank section of described bent axle is then concentric with cylinder body, described bent axle is provided with hinge wheel by bearing, bearing and door assembly with hinge and glass in right hand and left slide plate is linked respectively inside and outside described hinge wheel, described door assembly with hinge and glass in right hand and left slide plate is arranged on transfer rod, described cylinder body both sides arrange shaft cylinder cap and closed cylinder cap respectively.
Described eccentric wheel two ends are by the large and small bearing supporting of eccentric wheel, and described crankshaft two end is by the large and small bearing supporting of bent axle.
The rotary type blower fan of band bent axle of the present invention, 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 rotor (bent axle) rotates, door assembly with hinge and glass in right hand and left slide plate is driven to operate in cylinder body, take hinge axis as gyration center due to slide plate, so when rotating, slide plate cylindrical can be controlled do not contact with inner chamber of cylinder block, occur without friction running, the linear velocity that this structure solves rotary type blower fan and produces because of friction limits, can rotating speed be significantly improved, under equal flow, greatly reduce volume, or the flow of several times can be realized in equal volume.
