Abstract
The utility model relates to a connection structure of hub disk and hub, its characterized in that: the outside terminal surface of rim plate get on the bus level and smooth bright and clean anchor ring (1) of a concave yield, the external diameter of anchor ring (1) slightly is greater than hub external diameter (3), rim plate hole (4) are detained (5) with the hub ramus externus and are cooperateed, the terminal surface of the processing in close contact with of anchor ring (1) and hub, the hub has been got on the bus and has been welded cut (7), leave between the root of welding cut (7) and rim plate hole (4) and weld clearance (6), anchor ring (1) and hub external diameter (3) welding, the rim plate passes through welding seam A (2) welding with the hub, weld between rim plate hole (4) and welding cut (7) and the welding clearance (6), the rim plate passes through welding seam B (8) welding with the hub. Simple structure, reduce manufacturing cost, simplified process, overcome impeller hub and be difficult to riveting and the rivet not hard up problem that the riveting back appears, guaranteed the intensity and the rigidity of processingquality and impeller.
Description
Technical field
The utility model relates to a kind of centrifugal blower impeller, is specifically related to a kind of wheel disc of centrifugal blower impeller and the linkage structure of wheel hub.
Background technique
Centrifugal blower impeller is due at high rotating speed operate under rotation, to the intensity of impeller and rigid requirements higher, the wheel disc of impeller and wheel hub many employings solid forging structure or riveting, when lots of production is little, the forge piece blank reheating of solid forging structure is difficult to obtain, forging process amount is large, and manufacture cost is high; When adopting riveting, because hub relative diameter and volume are large, impeller internal space is little, riveting operation space is restricted, make riveted joint difficult processing to carry out, easily occur loosing of rivet phenomenon when riveting tight and impeller operation, adverse influence is produced to the normal work of blower fan.
Summary of the invention
The purpose of this utility model is to solve above-mentioned deficiency, provides the linkage structure of a kind of simple and practical wheel disc and hub welding, and can ensure intensity and the rigidity of centrifugal blower impeller.
For achieving the above object, the technical solution of the utility model is: the linkage structure of a kind of hub disk and wheel hub, it is characterized in that: the end face outside of wheel disc is got on the bus a recessed smooth bright and clean toroidal surface (1), the external diameter of toroidal surface (1) is slightly larger than hub outside diameter (3), wheel disc endoporus (4) and wheel hub prop up outward to be detained (5) and matches, the end face of the processing close contact of toroidal surface (1) and wheel hub, wheel hub has been got on the bus welding cut (7), welded gaps (6) is left between the root of welding cut (7) and wheel disc endoporus (4), toroidal surface (1) welds with hub outside diameter (3), wheel disc and wheel hub are by weld seam A(2) weld, wheel disc endoporus (4) welds with welding between cut (7) and welded gaps (6), wheel disc and wheel hub are by weld seam B(8) weld
Described wheel disc endoporus (4) and wheel hub prop up outward to be detained (5) and adopts transition fit, to ensure accurate positioning.
The height that described wheel hub props up button (5) is outward 1 ~ 2mm, to ensure the through welding of weld seam.
Described welded gaps (6) is 3 ~ 4mm, to ensure the intensity of weld seam.
Described weld seam A(2), weld seam B(8) be the circumferential weld of three layers of welding bead composition, postwelding does Stress relieving annealing process.
The beneficial effects of the utility model are: structure is simple, reduce cost of production, simplifies manufacturing process, overcomes the loosing of rivet problem that impeller hub is difficult to rivet and occur after riveted joint, ensure that intensity and the rigidity of quality of processing and impeller.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1,2,3, the linkage structure of a kind of hub disk and wheel hub, it is characterized in that: the end face outside of wheel disc is got on the bus a recessed smooth bright and clean toroidal surface 1, the external diameter of toroidal surface 1 is slightly larger than hub outside diameter 3, wheel disc endoporus 4 and wheel hub prop up button 5 outward and adopt transition fit, to ensure accurate positioning, the height that wheel hub props up button 5 is outward 1 ~ 2mm, to ensure the through welding of weld seam; The end face of the processing close contact of toroidal surface 1 and wheel hub, wheel hub has been got on the bus and has been welded cut 7, and leave welded gaps 6 between the root of welding cut 7 and wheel disc endoporus 4, welded gaps 6 is 3 ~ 4mm, to ensure the intensity of weld seam; Toroidal surface 1 welds with hub outside diameter 3, wheel disc is welded by weld seam A2 with wheel hub, and wheel disc endoporus 4 welds with welding between cut 7 and welded gaps 6, and wheel disc is welded by weld seam B8 with wheel hub, weld seam A2, weld seam B8 are the circumferential weld of three layers of welding bead composition, and postwelding does Stress relieving annealing process.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
