Abstract

Un giunto a frizione di una macchina utensile a comando elettrico, in particolare una cesoia per siepi o un trapano, con almeno una molla a tazza di forma anulare fra una ruota dentata esterna ed una interna deve garantire, con una costruzione compatta, un elevato momento di risposta il più preciso possibile. La molla a tazza (15) fa presa in direzione tangenziale con il suo perimetro interno (16) ad accoppiamento di forma con la ruota dentata interna (9) e si appoggia nel tratto del perimetro interno (16) assialmente sulla ruota dentata interna (9). La molla a tazza (15), nel tratto (18) del suo perimetro esterno, aderisce assialmente con accoppiamento ad attrito alla ruota dentata esterna (4).
