Abstract

"PEçA DE MãO MéDICA OU DENTAL-MéDICA (CONTRA-âNGULO, PEçA DE MãO) QUE TEM NO MìNIMO UMA PEçA ROTATIVA". A invenção refere-se a uma peça de mão médica ou dental-médica (3) que tem uma peça rotativa (12), em particular um motor de turbina (15a). Para melhorar a peça de mão com relação à construção pequena, ruído de operação e construção económica, é fornecido um mancal de rolamento (21) para a finalidade de montar a peça rotativa (12), tendo no mínimo duas fileiras de corpos de rolamento arranjadas uma junto da outra.
