Abstract
The utility model relates to a rotatory circle micromatic setting of high speed centrifugation fan import stator, including the rotatory circle of import, hexagon socket head cap screw, eccentric cover, guide bearing, plain washer and centre circle, rotatory circle sets up in the centre circle inboardly, installs eccentric cover in the guide bearing, and guide bearing and inner circle are provided with the plain washer within a definite time, and eccentric cover, guide bearing and plain washer are installed through hexagon socket head cap screw and is circled in. The utility model discloses simple structure, the design compactness, convenient to use uses on the high speed centrifugation fan of suitable all specifications, is interference fit between eccentric cover and bearing, and the zero clearance is just imported and is formed rolling friction between rotatory circle and the guide bearing, reduces the resistance, can guarantee the rotation and enclose steady rotation, is favorable to ensureing the concentricity.
Description
Technical field
The utility model relates to a kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane, belongs to frame for movement technical field.
Background technology
In the prior art, the rotation circle of high-speed centrifugal fan entry guide vane and centre circle are matched in clearance, spacing by spacing pressing plate. When rotation, rotation circle is plane contact with centre circle, and frictional force is large, and both radial fit gaps are larger, can produce rotation circle and centre circle decentraction, causes rotation to iris out existing bite phenomenon, causes the entry guide vane blade cannot normal rotation; Secondly the wall thickness of rotation circle is thinner, processing difficulties, and after processing, form error is larger, and concentricity is difficult to ensure.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane simple in structure, compact to design is provided.
The utility model adopts following technical scheme: a kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane, comprise import rotation circle, hexagon socket head cap screw, eccentric bushing, guide bearing, plain washer and centre circle, described import rotation circle is arranged at centre circle inner side, in described guide bearing, eccentric bushing is installed, between described guide bearing and centre circle, be provided with plain washer, described eccentric bushing, guide bearing and plain washer are arranged on centre circle by hexagon socket head cap screw.
Further, between described eccentric bushing and guide bearing, be interference fit.
Further, the external diameter center of described eccentric bushing and guide bearing endoporus centre deviation are a, and the span of a is 0.5～1.5mm.
Further, the surface of described guide bearing is W type and can forms rolling friction with import rotation circle.
The utility model is simple in structure, compact to design, easy to use, on the high-speed centrifugal fan of applicable all specifications, using, is interference fit between eccentric bushing and bearing, gapless, and form rolling friction between import rotation circle and guide bearing, reduce resistance, can ensure the uniform rotation of rotation circle, be conducive to guarantee concentricity.
Brief description of the drawings
Fig. 1 is the utility model structural principle schematic diagram.
Fig. 2 is local structure for amplifying schematic diagram of the present utility model.
Reference numeral: import rotation circle 1, hexagon socket head cap screw 2, eccentric bushing 3, guide bearing 4, plain washer 5, centre circle 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of rotation circle micromatic setting of high-speed centrifugal fan entry guide vane, comprise import rotation circle 1, hexagon socket head cap screw 2, eccentric bushing 3, guide bearing 4, plain washer 5 and centre circle 6, import rotation circle 1 is arranged at centre circle 6 inner sides, eccentric bushing 3 is installed in guide bearing 4, between eccentric bushing 3 and guide bearing 4, it is interference fit, the external diameter center of eccentric bushing 3 and guide bearing 4 endoporus centre deviations are a, the span of a is 0.5～1.5mm, between guide bearing 4 and centre circle 6, be provided with plain washer 5, eccentric bushing 3, guide bearing 4 and plain washer 5 are arranged on centre circle 6 by hexagon socket head cap screw 2, the surface of guide bearing 4 is W type can form rolling friction with import rotation circle 1.
Operation principle: centered by guide bearing 4 endoporus, fine setting eccentric bushing 3, make pivot and centre circle 6 centres of import rotation circle 1, guide bearing 4 and import rotation circle 1 close contact, gapless, when operation, the 1 energy uniform rotation of import rotation circle, thus drive entry guide vane blade normal rotation.
