Filed:

Sep 1, 2006

Appl. No.:

11/515467

Inventors:

Shepard Lynn Hockaday - Benson NC, US
Candace Stephenson Barefoot - Dunn NC, US
George Dane Goodson - Dunn NC, US
Timothy Glenn King - Coats NC, US
Ray John Matthews - Willow Spring NC, US
John David Reece - Erwin NC, US

Pimol Ballard Vonkchalee - Apex NC, US

International Classification:

H01R 39/18
H01R 39/20
C04B 35/64

US Classification:

310248, 310252, 264603

Abstract:

Systems and methods for electrical component, e.g., brush, manufacture are provided that control grain orientation. The systems and methods utilize hot pressing techniques to enhance the properties and functionalities of the electrical components/brushes. An intermediate work product characterized by a grain orientation is initially formed through a conventional pressing technique. The conventionally-pressed intermediates are positioned within a cavity/die with the grain orientation in a predetermined orientation relative to the hot press force to be applied thereto. The hot pressed final product exhibits superior resistivity, strength and apparent density/durability. Surface features may be formed on the face(s) of the final work product during the hot pressing step that cannot be achieved in conventional processing techniques. Advantageous articles of manufacture, e.g., brushes and brush assemblies, are also disclosed.

US Classification:

310233

Abstract:

Addressed herein are commutators and methods of manufacturing them. The methods permit the carbonaceous material and core of a commutator to be molded simultaneously, rather than in a two-step process, and can eliminate one of two curing procedures used in connection with other manufacturing techniques. The necessity of machining the inner surface of the commutator shell to remove undesired excess phenolic or other material additionally is avoided by use of the techniques detailed herein. Commutators formed according to these methods may have increased useful lives and provide better performance than others presently available.
