US Patent:

55540040, Sep 10, 1996

Filed:

Jul 27, 1995

Appl. No.:

8/508226

Inventors:

Timothy J. Stewart - Akron OH

Assignee:

Ametek, Inc. - Kent OH

International Classification:

F04D 2928

US Classification:

416185

Abstract:

A molded impeller fan assembly has a backing plate and a plurality of blades extending generally orthogonally upwardly therefrom. A V-shaped buttress is formed at the transition of each blade to the backing plate. Each buttress is defined by a pair of opposed walls which are formed where the backing plate curves gradually upward toward the blade apex. A V-shaped indentation is disposed between the walls in a side of the backing plate opposite the blades. The walls of the buttress serve to transfer centrifugal and impact forces from the blades to the backing plate.

International Classification:

F16C 4300

US Classification:

384537

Abstract:

A bearing retaining device is provided to maintain a shaft bearing within a housing. In one embodiment the device has a housing with a central bore into which is received a bearing. The bearing rests upon a bearing seat and is maintained in the housing by a retainer clip. The retainer clip is generally disc shaped with a number of spring tab members extending at an angle therefrom. When the retainer clip is rotated within the housing, the spring tab members are compressed by brush holders protruding into the housing and above the retainer seat. The spring tab members spring back to position after clearing the protrusions and dimpled ears formed in the retainer clip body frictionally engage the brush holders. The trailing edge of each spring tab member grips the side of each brush holder. The bearing is thereby locked into the housing and displacement and vibration thereof are eliminated.

Inventors:

Timothy J. Stewart - Akron OH

Assignee:

Ametek Technical Motor Division - Kent OH

International Classification:

H02K 516

US Classification:

310 90

Abstract:

A ground lead connection is provided to electrically ground a motor armature shaft. In one embodiment the device has a motor housing in which is mounted a bearing. An armature shaft is journaled in the bearing and a ground lead is attached to the bearing. The bearing is provided with a counter bore socket which receives a terminal from the ground lead. The terminal includes a ferrule and a plug which has flared fingers. When connected, the plug engages the bore of the socket and the fingers engage the counter bore to permanently prevent removal of the terminal from the socket. The shaft is thereby grounded via the bearing without the need for numerous parts.
