DISPOSITIVO DE TRANSMISION PARA MAQUINAS TRAZADORAS.

摘要

The present invention relates to transmission device for plotters characterized in that it comprises at least a freely rotating first wheel (2) arranged between the motor tube (5) and the winder tube (6) of a plotter, such that the rotation of the motor tube (5) is transmitted to said winder tube (6) through said freely rotating first wheel (2). It may also comprise a pair of freely rotating wheels (3) that are constrained to rotate together by contact, arranged between said motor tube (5) and said winder tube (6), one wheel of said pair of wheels (3) being in contact with said motor tube (5) and the other wheel of said pair of wheels (3) being in contact with said winder tube (6). It facilitates the change from direct to inverse transmission without having to use tools, and it achieves a clutch effect as the result of the sliding of the wheels with respect to the tubes.
