CONICAL PLANETARY GEAR REDUCER HAVING A CENTRAL WHEEL

摘要

The invention relates to a conical planetary gear reducer having a central wheel, which yields high transmission ratios and which is used for regulating the rotative speed in linkages. According to the invention, the conical planetary gear reducer with a central wheel is provided, in the satellite wheel body (7), with some axial recesses (a) through which some radial wings (b) of couplings (15) extend to some channels (c) in the body (3), by means of which said wheel is blocked on rotation.
