Abstract

bomba de caixa de rolamentos com perfil reduzido resistente à abrasão. uma bomba centrífuga tem um difusor estacionário com um furo. um mancal de impulso é pressionado para dentro do difusor e tem um furo interior curvo. um corredor impulso ter um exterior curvo é correspondentemente e estreitamente recebido pelo interior rolamento de encontro. o corredor impulso é introduzido a um eixo e transmite a pressão de um impulsor rotativo para o difusor através do rolamento de encosto. aq superfície curva do rolamento de impulso permite a manipulação de impulso tanto axial e radial, sem a necessidade de vários rolamentos axiais. o aumento da área de superfície curva do rolamento de impulso pode também lidar com cargas mais elevadas.
