Abstract

ROLL FIXING SYSTEM IN SUGAR CANE HARVESTING UNITS. This utility model is concerned with a system for securing the rollers in hydraulic motors present in sugar cane cutting and collecting machines, in machines known in the state of the art for coupling the rollers to hydraulic motors by means of a system. The gear unit comprises an outer body provided with a plurality of wedges, which engages a screwed hub in the marginal portion of the roll, which hub has a series of dragging armholes. The utility model proposed here comprises a system of fixing the cylindrical rotor in the simplest and most robust hydraulic motor, since the armholes and drag wedges are eliminated and replaced respectively by an external body with a hexagonal profile shoulder. or with a similar geometric profile, which makes the coupling much simpler and more robust, as well as the production of parts requiring a smaller number of machining processes which consequently reduces their cost.
