Abstract

L'invenzione realizza una testa levigatrice comprendente un carter (22), supportante una pluralità di mole (124; 224), sostenuto da un albero centrale (2) collegato ad una presa di moto (50) e contenente pignoni satelliti (13) posti in rotazione tramite cinematismi. Ciascuna di dette mole (124) è fissata all'estremità (123) di un perno (122), collegato eccentricamente nel foro (16) di uno di detti pignoni satelliti (13), provvisto di un corpo sferico (125) atto a consentire, durante la rotazione di detta testa levigatrice, un moto conico di rivoluzione dell'asse longitudinale (129) di detto perno (122) e della mola ad esso collegata rispetto all'asse longitudinale del relativo pignone satellite (13), contemporaneamente ad un moto di rivoluzione di detta mola rispetto all'asse di rotazione (100) della testa levigatrice medesima.The invention realizes a sanding head comprising a carter (22), supporting a plurality of grinding wheels (124; 224), supported by a central shaft (2) connected to a power take-off (50) and containing satellite sprockets (13) placed in rotation through kinematic mechanisms. Each of said wheels (124) is fixed to the end (123) of a pin (122), eccentrically connected in the hole (16) of one of said satellite sprockets (13), provided with a spherical body (125) suitable to allow , during the rotation of said honing head, a conical revolution motion of the longitudinal axis (129) of said pin (122) and of the grinding wheel connected to it with respect to the longitudinal axis of the relative satellite pinion (13), simultaneously with a motion revolution of said grinding wheel with respect to the rotation axis (100) of the polishing head itself.
