International ClassB23P 011/02AbstractThe present invention provides a method of assembling a fan where the fan itself comprises a plurality of fan components and a housing portion having an open end with an interior area defined by component receiving regions. The method includes positioning the housing portion with its open end up and then locating the components in set positions in the housing portion with those set positions being initially maintained by cooperative fitting of the components in the component receiving regions. After the components have been located in their set positions, the fan is then secured by mechanical locking means to releasably secure the components in the housing portion.Field of SearchThrough resilient mediaBy snap fit Assembling a subassembly, then assembling with a second subassembly Axial blower or fan PLURAL RUNNERS SUPPORTED FOR RELATIVE MOTION OR ON SEPARATE SHAFTS With means for selective runner operation or drive shaft connection Access opening through portion of casing or cover Casing having multiple parts releasably clamped (e.g., casing seal, etc.) INCLUDING SHAFT TRANSMISSION TRAIN, BRAKE, CLUTCH, OR ATTENDANT ACTUATED DRIVE MEANS | |
