Abstract
"ROLAMENTO DE ESFERAS E UNIDADE DE ROLAMENTO DE ESFERAS". A presente invenção refere-se a um rolamento de esferas (6) e uma unidade de rolamentos de esferas, especialmente para aparelhos de altas rotações como turbinas dentais, porta-ferros angulares dentais, bombas turbo moleculares ou semelhantes, com esferas (4), que são dispostas entre um anel interno de rolamento (7) e um anel externo de rolamento (8), que em operação em rotações, especialmente durante a fase de partida, possui características de operação amplamente melhores, sendo que ao mesmo tempo é impedida uma sobrecarga do rolamento de esferas ou da unidade de rolamentos de esferas em virtude da tensão prévia ou em virtude de divergências de geometria e/ou de imprecisões de montagem. Isto, de acordo com a presente invenção, é alcançado pelo fato de que é previsto um dispositivo (4) para a geração de uma força de tensão dependendo do número de rotações.
