Abstract

ESTA INVENCION PROPORCIONA UN DISEÑO DE UN PORTADOR PARA UN MONTAJE GIRATORIO QUE INCLUYE DOS BOLAS QUE GIRAN LIBREMENTE MONTADAS EN UN EJE DE ROTACION DEL MONTAJE Y SEPARADAS AXIALMENTE, DE FORMA QUE UNA QUEDA CERCA DEL EXTREMO AXIAL DEL MONTAJE. CADA BOLA ESTA RESTRINGIDA POR UNA SUPERFICIE DEL PORTADOR CONCAVA (PREFERIBLEMENTE CONICA O FRUSTOCONICA) Y UNA SUPERFICIE DEL PORTADOR CONCAVA FIJA CORRESPONDIENTE DE UN MONTAJE UNIDO AL ARMAZON, CAJA O UNA ESTRUCTURA SIMILAR NO GIRATORIA. PREFERIBLEMENTE, UNO DE LOS MONTAJES FIJOS ESTA UNIDO A UN MUELLE COMPRIMIBLE PARA PROPORCIONAR AL MONTAJE UNA PRECARGA AXIAL CONTROLADA. LAS BOLAS ESTAN SUSTANCIALMENTE ENCERRADAS Y SE PROPORCIONA UN LUBRICANTE EN LA CAVIDAD CERRADA. EN EL MODELO PREFERIDO, EL MONTAJE GIRATORIO ES UN MONTAJE DE UN ACCIONADOR GIRATORIO DE UNA UNIDAD DE DISCO. COMPARADO CON LOS DISEÑOS DE PORTADORES DE BOLAS CONVENCIONALES, EL DISEÑO PRESENTE REDUCE EL NUMERO DE PARTES Y EL VOLUMEN ESPACIAL OCUPADO POR LOS PORTADORES, REDUCE LAS HISTERESIS Y MEJORA LA RESISTENCIA CONTRA A LOS GOLPES.
