RECIPROCATING DRIVE

摘要

Vibration in machines including a reciprocating working member, e.g. gang saws represents a serious problem. The problem is solved by a simple drive for such a machine including a motor driven shaft carrying a pair of gears for operating a planetary transmission, which includes a pair of gear trains symmetrical with respect to the plane of reciprocation of the working member, first and second opposed, balanced counterweights associated with each gear train for balancing forces generated by reciprocation of the working member, and third and fourth opposed, balance counterweights for balancing forces generated by the transmission means.
