Abstract

amortecedor e / ou absorvedor de vibração. um amortecedor e / ou absorvedor de vibração linear inclui um veio central (12) tendo regiões de rolamento (18) e regiões de contato de fricção (20) e um alojamento (2) incluindo conjuntos de pontas (22) que são montados com uma pequena folga radial para localização precisa nas regiões de rolamento (18) para deslocamento axial em relação ao veio central (12) ao longo de um eixo central (x), os conjuntos de pontas (22) cada um incluindo pontas resilientes (38) que se estendem axialmente a partir das respectivas seções do corpo (26) e têm faces de contato (40) que engatam resilientemente, ou seja, são pressionadas pela resiliência das pontas (40) em contato com as superfícies de fricção (20) das regiões de contato do veio central (12), em que o deslocamento linear relativo entre o veio central (12) e o alojamento (2) é oposto pelo contato de fricção entre as superfícies de fricção (20) e as faces de contato (40).
