Abstract

uma bomba de vácuo de compactação a seco, especialmente uma bomba helicoidal, apresenta dois elementos de rotor (14) dispostos em uma câmara de sucção (12), os quais estão portados por um respectivo eixo de rotor (22). duas extremidades de eixo dos eixos de rotor (22) projetam-se através da parede lateral (28) do alojamento de bomba (10). nas duas extremidades de eixo (28) está disposta uma respectiva roda de correia dentada (38). estão previstos ainda um dispositivo de acionamento e um motor elétrico para acionamento do eixo de rotor (22). o acionamento dos eixos de rotor (22) ocorre, de acordo com a invenção, através de uma correia dentada (40). para poder utilizar uma correia dentada para acionamento, está prevista uma folga de flancos de rotação entre os dois elementos de rotor (14) maior que ± 0,75%, especialmente maior que ± 1º.
