摘要:
Coupling device (16) for connecting a transverse fan (14) to the drive shaft of an electric motor (10). Portions of the drive shaft (12) are particularly shaped so as to fit into correspondingly shaped portions (40) in the coupling device. The coupling device further includes locking structure (48) for securing the coupling device to the transverse fan. The coupling device is preferably a single molded unit consisting of a thermoplastic elastomer material.
摘要:
A single piece drive hub connects the drive shaft of a motor to a transverse fan assembly. The structure of the single piece drive hub allows for the drive hub to be easily inserted and locked into place within the one end of the transverse fan assembly. The drive hub is preferably fabricated from a thermoplastic elastomer material that allows a diaphragm portion of the single piece drive hub to flexibly distort if necessary.
