Connection structure of hub disk and hub

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.
