FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Proposed drive comprises drive shaft and two gear wheels, two con-rods, two cranks hinged to con-rods and fitted on coaxial crankshafts with wheelwork each including crankshaft with gear wheel fitted thereon and, if required, countershafts locked axially and provided with engaged gear wheels meshed with crankshaft gear wheel, and counterweights fitted on crankshaft and/or countershaft. Closure of side clearances in gearing during stand reciprocation is ensured by providing the drive with extra shaft to engage similar gear wheels of two wheelworks by extra gear wheels fitted on said shaft. Note here that said extra shafts floats axially and is furnished with axial pressure mechanism engaged with housing. All gear wheels represent helical gears with opposite direction of teeth. Drive shaft is arranged parallel about axis of crankshafts while drive gears are fitted directly at drive shaft to engage with similar gear wheels of wheelwork.
EFFECT: new design.
