CA 2471229
Devices and methods of use for brush holders are disclosed. A brush holder including an over-center locking device is disclosed. Also illustrated are methods and devices for maintaining brush pressure against a moving conductive surface using a spring without a back plate. Methods and devices for routing current from a brush to an output location without conducting through a brush box are shown. A system for ready removal and replacement of brushes, contacts and springs is disclosed. Also included are mechanisms and methods for preventing a brush from falling downward or out during removal of the brush. Methods and devices for cutting off current flow without creating arcing or shorting between a brush and collector ring or other moving conductive surface are presented as well.
L'invention concerne des dispositifs et des procédés d'utilisation pour porte-balais. Elle concerne également un porte-balais comprenant un dispositif de verrouillage décentré, ainsi que des procédé et des dispositifs destinés à maintenir la pression des balais contre une surface conductrice mobile au moyen d'un ressort sans plaque arrière. L'invention se rapporte en outre à des procédés et dispositifs permettant d'acheminer le courant depuis un balai jusqu'à un emplacement de sortie sans conduction à travers une gaine de porte-balais, ainsi qu'à un système de retrait et de remplacement rapide des balais, des contacts et des ressorts. Cette invention concerne enfin des mécanismes et des procédés destinés à empêcher un balai de tomber vers le bas ou à l'extérieur pendant son retrait, ainsi que des procédés et des dispositifs servant à couper la circulation du courant sans production d'arc électrique ou de court-circuit entre un balai et une bague collectrice ou une autre surface conductrice mobile.
