Abstract

TRANSMISSãO DE ROSCA DE ESFERA. A presente invenção refere-se à transmissão de rosca de esfera, com um fuso de rolo de esfera (1) e porca de fuso (2) sobre ele disposta, sendo que esferas (3) estão dispostas passíveis de circulação sem-fim em um canal de esfera (6) sem-fim limitado por pistas de esfera (4, 5) do fuso de rolamento de esfera (1) e da porca de fuso (2), sendo que o canal de esfera (6) apresenta um segmento de carga (7) enrolado em torno do fuso de rolamento de esfera (1), cujo início e fim estão unidos entre si sem-fim por um segmento de retorno (8) isento de carga, sendo que respectivamente ao menos duas e no máximo quatro esferas (3) estão alojadas em uma gaiola de esfera (10, 22) comum, cujas bolsas de gaiola (11) alojam respectivamente uma das esferas (3), sendo que a gaiola de esfera (10, 22) apresenta em suas extremidades axiais e entre esferas (3) mutuamente vizinhas pratos (12, 15) engatando nas pistas de esfera (4, 5), e em seus lados voltados para as esferas (3) providos de um alojamento (14) cóncavo para as esferas (3).
