Abstract

"ELEMENTO DE MáQUINA". A invenção refere-se a um elemento de máquina, que está provido, pelo menos, ao longo de uma parte de seu comprimento axial, com uma primeira denteação (2.1), na forma de filetes de rosca que passam em sua superfície de revestimento cilindrica, para um acionamento de rosca. Este elemento é caracterizado pelo fato de que os filetes de rosca são produzidos através de uma laminação contínua do perfil na direção axial bastante conhecida, sendo que a laminação continua do perfil é empregada parcialmente continua, correspondendo à dilatação axial desejada dos filetes de rosca.
