Abstract

Inventia se refera la un mecanism cu filet cu bile folosit pentru transformarea miscarii de rotatie într-o miscare de translatie, folosit la deplasarea elementelor mobile, în constructia masinilor -unelte. mecanismul cu filet cu bile, conform inventiei, este astfel alcatuit încît reducerea bilelor în filet se face pe o suprafata plana între flancurile filetului, iar pentru ghidarea laterala sunt prevazute elemente directoare, formate din doua piese de deviere fixate de fus.
