Abstract
The present invention relates to a kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane, including import rotation circle, hexagon socket head cap screw, eccentric bushing, guide bearing, plain washer and centre circle, rotation circle is arranged on the inside of centre circle, eccentric bushing is installed in guide bearing, plain washer is provided between guide bearing and inner ring, eccentric bushing, guide bearing and plain washer are arranged on centre circle by hexagon socket head cap screw.The present invention is simple in construction, it is compact to design, it is easy to use, used on the high-speed centrifugal fan for being adapted to all specifications, be interference fit, gapless between eccentric bushing and bearing, and form rolling friction between import rotation circle and guide bearing, resistance is reduced, rotation circle uniform rotation is ensure that, it is advantageously ensured that concentricity.
Description
Technical field
The present invention relates to a kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane, belong to mechanical structure technology neck
Domain.
Background technology
In the prior art, the rotation circle of high-speed centrifugal fan entry guide vane coordinates with centre circle for gap, passes through spacing pressure
Plate is spacing.During rotation, rotation circle is plane contact with centre circle, and frictional force is big, and both radial fit gaps are larger, can produce rotation
Turn-take and centre circle decentraction, cause rotation to iris out existing bite phenomenon, cause entry guide vane blade can not normal rotation；Secondly rotate
The wall thickness of circle is relatively thin, processing difficulties, and form error is larger after processing, concentricity it is difficult to ensure that.
The content of the invention
It is an object of the invention to overcome deficiency of the prior art, there is provided a kind of high speed simple in construction, compact to design
The rotation circle micromatic setting of centrifugal blower entry guide vane.
The present invention is adopted the following technical scheme that：A kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane, including
Import rotation circle, hexagon socket head cap screw, eccentric bushing, guide bearing, plain washer and centre circle, the import rotation circle are arranged in centre circle
Eccentric bushing is installed in side, the guide bearing, plain washer is provided between the guide bearing and centre circle, the eccentric bushing, led
It is arranged on to bearing and plain washer by hexagon socket head cap screw on centre circle.
Further, it is interference fit between the eccentric bushing and guide bearing.
Further, the external diameter center of the eccentric bushing and guide bearing endoporus centre deviation are a, and a span is
0.5~1.5mm.
Further, the surface of the guide bearing can form rolling friction in W types with import rotation circle.
The present invention is simple in construction, compact to design, easy to use, is used on the high-speed centrifugal fan for being adapted to all specifications, partially
The heart is covered being interference fit between bearing, gapless, and import rotation is enclosed and rolling friction is formed between guide bearing, reduces resistance
Power, ensure that rotation circle uniform rotation, it is advantageously ensured that concentricity.
Brief description of the drawings
Fig. 1 is principle schematic diagram of the present invention.
Fig. 2 is partial enlargement structural representation of the invention.
Reference：Import rotation circle 1, hexagon socket head cap screw 2, eccentric bushing 3, guide bearing 4, plain washer 5, centre circle 6.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-Figure 2, the rotation circle micromatic setting of a kind of high-speed centrifugal fan entry guide vane, including import rotation circle
1st, hexagon socket head cap screw 2, eccentric bushing 3, guide bearing 4, plain washer 5 and centre circle 6, import rotation circle 1 are arranged at the inner side of centre circle 6, lead
Eccentric bushing 3 is installed into bearing 4, is interference fit between eccentric bushing 3 and guide bearing 4, the external diameter center of eccentric bushing 3 is with being oriented to
The endoporus centre deviation of bearing 4 is a, and a span is 0.5~1.5mm, and plain washer 5 is provided between guide bearing 4 and centre circle 6,
Eccentric bushing 3, guide bearing 4 and plain washer 5 are arranged on centre circle 6 by hexagon socket head cap screw 2, and the surface of guide bearing 4 is in W type energy
Enough and import rotation circle 1 forms rolling friction.
Operation principle：Centered on the endoporus of guide bearing 4, finely tune eccentric bushing 3, make import rotation circle 1 pivot with
With one heart, guide bearing 4 is in close contact at the center of centre circle 6 with import rotation circle 1, gapless, during operation, and import rotation circle 1 can be at the uniform velocity
Rotate, so as to drive entry guide vane blade normal rotation.
