发明名称 Fan with individual flow segments connected to a hub with a prefabricated thermoplastic strip
摘要 This fan is provided with an impeller (1), having a hub (2), and with a casing surrounding the impeller (1). The impeller (1) has individual flow segments (4) connected to the hub (2) and to one another and in each case enclosing a flow duct (5), and a shaft connected to the hub (2) and extending along an axis (3). The object is to provide a fan which has an impeller which can be easily produced from a plastic and is suitable for comparatively high operating speeds. This is achieved by the flow segments (4) being connected with a form fit to the hub (2), and by the fastening of the flow segments (4) being reinforced by means of at least one shrouding (13, 14) of a prefabricated thermoplastic strip reinforced with continuous fibers, the thermoplastic strip having been briefly heated and fused with the layer respectively applied previously during the winding of the shrouding (13, 14).
