Abstract

MéTODOS PARA CONTROLAR A INSTABILIDADE EM ROLAMENTOS DE PELìCULA DE FLUIDO. Trata-se de um método para controlar a instabilidade em rolamentos de película de fluido mediante a utilização de um rolamento magnético em combinação com um rolamento de película de fluido (quer seja um rolamento de munhão cilíndrico, um rolamento elíptico, um rolamento de meio deslocamento, um rolamento de múltiplos lóbulos, um rolamento de folha delgada ou um rolamento de coxim de inclinação, não importa realmente), em que o rolamento de película de fluido serve como rolamento de suporte de carga principal e o rolamento magnético controla a instabilidade do rolamento de película de fluido. Esta combinação eficiente resulta em rolamentos que podem ser utilizados a altas velocidades sem ter problemas tanto de estabilidade quanto de confiabilidade. Um método alternativo para controlar a instabilidade nos rolamentos de película de fluido consiste em perturbar o fluxo na direção axial, por exemplo, um rolamento de luva (de munhão) pode ser manufaturado de maneira tal que o eixo geométrico do rolamento fica enviesado com o eixo geométrico do eixo mecânico, ou um rolamento de geometria variável pode ser manufaturado para permitir o desalinhamento angular do rolamento.
