Redutor para retrofitting CNC de uma fresadora manual

Abstract

A machine of milling belong of Federal University of Technology - Câmpus Ponta Grossa was been parked. A student group mentored by professor Doctor Marcelo Vasconcelos de Carvalho determined to carry out a retrofitting in this machine with purpose of become a CNC milling with a step engine already existent. After to connect the step engine directly to axis of machine, was realize that the step engine there did not have the torque to move the table. To continue the project of retrofitting, a speed reducer was design by presenting a train of worm gear and spur gear. To design of speed reducer was necessary to design the trains of gears, the axis, the key and bearing. On the final of the project was realized that step engine chosen wasn’t powerful enough to this activity.
