30-19 PROCEDEU DE DETERMINARE A RANDAMENTULUI CUPLEI CINEMATICE TIP ROLĂ CILINDRU

METHOD FOR DETERMINING THE EFFICIENCY CYLINDER
ROLL CINEMATIC COUPLE
In this work is analyzed mechanical efiency by experimental research
using a device for helicoidally movement simulation.
The precision of helicoidally generation is determinate in relation
between normal force and acting torque. For accurate determination of the
measurements is made by electronic transducers for displacement and rotation.
Keywords: kinematic coupling, helical motion, rotation and displacement
