Abstract

mecanismo de aumento da rigidez para rolamento de suspensão magnética, rolamento de suspensão magnética e bomba de sangue. a presente divulgação se refere a um mecanismo de aumento de rigidez (23) para um rolamento de suspensão magnética (20), um rolamento de suspensão magnética (20) incluindo o mecanismo de aumento de rigidez (23) e uma bomba de sangue. o rolamento de suspensão magnética (20) compreende um estator (21) com dentes do estator (211) e um rotor (22) disposto dentro do estator (21). o mecanismo de aumento de rigidez (23) compreende: um ímã permanente do rotor (231), um ímã permanente do estator (232) e um corpo de acionamento axial (233). o ímã permanente do rotor (231) e o rotor (22) do rolamento de suspensão magnética (20) formam um conjunto de rotor, que tem uma estrutura assimétrica em relação ao plano principal (p) do rotor (22). o mecanismo de aumento de rigidez (23) é configurado, de modo que o ímã permanente do estator (232) gere uma força de atração radial para o ímã permanente do rotor (231) e o corpo de acionamento axial (233) gera uma força repulsiva axial para o ímã permanente do rotor (231), em que a magnitude da força repulsiva axial é variável com uma mudança de uma distância axial entre o corpo de acionamento axial (233) e o ímã permanente do rotor (231). o mecanismo de aumento de rigidez (23) pode aumentar a rigidez torcional do rotor (20) do rolamento de suspensão magnética (20) e facilitar a miniaturização do rolamento de suspensão magnética (20).
