  • Air guide assembly for an electric motor and methods of making
    Patent number: 5296769
    Abstract: An air guide and motor housing assembly for use in domestic and commercial vacuum cleaners is described wherein the assembly comprises an air guide having a center detail for engaging the motor housing to facilitate assembly of the components, and reduce creep, turbulence and vibration-induced noise. An air guide for use with a centrifugal fan is described wherein the air guide is mounted on a motor bracket using the same rivets that fasten a bearing assembly to the motor bracket. Alternative embodiments of the device are also described in which a step in an inner fan housing cooperates with a step projecting from the air guide to securely fasten the air guide to the motor assembly, and a center detail on the air guide engages the motor housing to secure the air guide thereto, thereby providing the same advantages.
