Abstract

LA MACHINE 10 COMPREND UN ARBRE DE PALPEUR 42 MONTE VERTICALEMENT DONT LE POIDS EST CONTREBALANCE PAR UN CONTREPOIDS PNEUMATIQUE 100. LE SYSTEME DE PROTECTION COMPREND DEUX ELEMENTS DE FREINAGE 239, 240 MONTES A PROXIMITE DE L'ARBRE DE PART ET D'AUTRE DE CE DERNIER. LES ELEMENTS DE FREINAGE SONT SOLLICITES EN ENGAGEMENT AVEC L'ARBRE PAR DES RESSORTS 230, 240 ET DES BIELLETTES 222, 226. UN VERIN PNEUMATIQUE 210 S'OPPOSE A L'ACTION DES RESSORTS TANT QU'IL EST ALIMENTE EN AIR SOUS UNE PRESSION SUFFISANTE. LORSQUE LA PRESSION D'ALIMENTATION DU VERIN DIMINUE, PAR EXEMPLE EN CAS DE PANNE DANS LE CIRCUIT D'ALIMENTATION, LES RESSORTS PROVOQUENT L'ENGAGEMENT DE FREINAGE DES ELEMENTS DE FREINAGE ARRETANT AINSI LA DESCENTE DE L'ARBRE DU PALPEUR. APPLICATION AUX MACHINES POUR RELEVES DIMENSIONNELS.
