Abstract
An improved head for polishers, comprising a planetary transmission mechanism between the drive shaft and wheel holder assembly claimed in utility model 129,621, is characterized essentially because of the two coaxially coupled bodies that constitute it, the central body receives the coupling elastic cardan shaft of the drive shaft, through the penetration of the crosspiece of said shaft between diametrically opposed slots of the upper extremity of the central body, while the latter externally presents a seat for the lower extremity of a coax spring, the upper end of which is it supports under the periphery of a disc joined axially with the drive shaft.
