Description
Technical field
The present invention relates to the electric fan technical field, more particularly relate to the inducer interconnection technique of axial flow fan with flow guide.
Background technique
Its inducer of the axial flow fan with flow guide of prior art generally is arranged on the axle, its rotation has passive rotation and active rotation dual mode, active mode mainly is by the outer rim at inducer the rotation of motor by the driven by motor wind wheel to be set, the inducer of this mode rotates comparatively steady, rotating speed is even, but the cost height needs to consume more electric energy; The passive type rotating manner generally is the outer installment set screw nut at inducer, by nut inducer is fixed on the stationary axle, and then a ring is set on the stationary axle externally, the inducer Placement of this structure exists the inducer rotational velocity to be difficult for the problem of regulating, if the fastening too tightly then difficult rotation of inducer of nut, Ruo Taisong then inducer rotates not steadily, occurs creeping and bad phenomenon such as swing, the easy loose or dislocation of trim simultaneously.In order to address this problem, someone has adopted the mode that fixedly prevents the axial motion of inducer by bearing pin, as application number is 97246055, the applying date is on November 28th, 1997, denomination of invention is the bindiny mechanism of rotary leaf fan inducer, comprise synchronous machine, inducer, connect axle bush, it is characterized in that: connect axle bush and be fastened on the axle of synchronous machine by straight pin, inducer is sleeved on and connects on the axle bush, the locking device retaining that the connection axle bush is provided with is on the inner plane of inducer, to prevent the axial motion of inducer; An end that connects axle bush is equipped with rosette.This bindiny mechanism complex structure, the cost height is installed inconvenience, and same speed is difficult for regulating.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of simple in structure, stability of rotation, the axial flow fan with flow guide inducer bindiny mechanism that rotating speed is even, the inducer rotating speed can make things convenient for adjusting as required.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of inducer bindiny mechanism of axial flow fan with flow guide, electric fan flabellum forward frame is provided with stationary axle, and this inducer is socketed on the stationary axle, and the end of stationary axle also is connected with trim, it is characterized in that, also is set with top pressure spring on stationary axle.
As further specifying of such scheme, on the stationary axle between trim and the inducer, also be socketed with the roof pressure circle, top pressure spring is arranged between roof pressure circle and the inducer trim.
Described roof pressure circle and inducer phase-contact surface are provided with the ring that protrudes from roof pressure circle surface; The another side of roof pressure circle is provided with circular groove, and an end of top pressure spring is arranged in the circular groove.
The inboard neutral position of trim is provided with erection column, and the other end of top pressure spring is socketed on the erection column.
Be socketed with the metal swivel nut that is spirally connected with stationary axle in the described erection column.
On inducer, also be fixed with metal axle sleeve with stationary axle socket place.
Also can be socketed with packing ring on the stationary axle between described inducer and the forward frame.
As another program of this patent, described top pressure spring is arranged between inducer and the electric fan flabellum forward frame.
The utility model adopts the beneficial effect of technique scheme to be:
One, the utility model can be realized any adjusting of inducer rotating speed from " slow in fast "; The utility model passes through damping function, can realize the step-less adjustment of inducer rotating speed speed: the damping function between the circular groove of the annular convex ring of roof pressure circle and the damping function between the inducer, roof pressure circle and the erection column of the damping function between the spring, spring and decoration device, realize the adjusting of inducer rotating speed;
Two, the utility model can effectively prevent the axial runout of inducer by the roof pressure of top pressure spring, stability of rotation, because its roof pressure effect can prevent that creeping of trim from coming off, the trim that has overcome prior art easily comes off, inducer rotates jiggly phenomenon simultaneously;
Three, the utility model is simple in structure, and cost is low; Mainly by roof pressure circle, trim and between the two top pressure spring constitute, need not install complicated shrinking device additional, part is few, assembling is simple, can operate by hand, cost of production is low.
