Abstract

Sewing machine equipped with a frame or frame, a main drive shaft supported in rotation on said frame, and a planetary drive device on said shaft, comprising a driving element, a reaction element and a wheel carrier or planetary elements said conductive element and said reaction element having coaxial surfaces of cooperative contact with the planetary elements, and a plurality of wheels or planetary elements supported by said carrier and arranged between said planetary contact surfaces, said planetary elements having surfaces peripherals in cooperative contact at diamentrally distant points with said contact surfaces with the planetary elements; characterized by the fact that the contact surfaces of said conductive element and of said reaction element with the planetary elements, and the peripheral surfaces of the planetary elements, include at each contact point a rubber or similar elastic material surface and that it increases the friction, said planetary elements being dimensioned, with respect to said cooperative contact surfaces with them, so that they slightly deform said elastic material at each contact point.
