METHOD OF MOUNTING AND LOCKING WORKING MEMBERS OF TECHNOLOGICAL MACHINES Russian patent published in 2002 - IPC

FIELD: mechanical engineering; automatic machines and automatic forge-and-press machines containing several working members working according to preset cyclogram. SUBSTANCE: drive member of main actuating mechanism made in form of single-throw crankshaft is set in one of extreme positions defining beginning of cycle of performance of preset technological process. Then, driven members of drive of working members of actuating mechanisms are shifted in turn and locked in accordance with sequence of their operation stipulated by cyclogram. Said shift is made at preset angular magnitude relative to single-throw crankshaft by means of keyless joint for which use may be made of clamping sets fitted between shaft and hub of driven member and made in form of split cylindrical rings with starting taper surfaces engageable with side spacer rings by means of screw joint As a result, preset cyclogram of working member operation may be changed in accordance with sizes of article being machined. EFFECT: possibility of obtaining optimal quality at reduced power requirements. 3 cl, 4 dwg
