    • A reciprocating saw 11 comprises an output shaft 21 mounted for reciprocal motion in a housing 13. A counterweight 27 is mounted in the housing for reciprocal movement relative to the output shaft. A first drive 37 is connected between a motor and the output shaft for reciprocally driving the output shaft. A second drive 39 is connected between the motor 19 and the counterweight for reciprocally driving the counterweight. The second drive 39 preferably comprises a pivot arm 41 pivotally mounted about an axis transverse to the output shaft for receiving at a first location a reciprocating input in a first direction 40 and for producing at a second location a reciprocating output in a second direction 42 different from the first direction. The first and second drives provide a compact, low vibration, relatively simple, counterbalanced drive train for the saw.
    • 一个往复锯输出轴21的11包括安装成用于往复运动的壳体13的配重27被安装在壳体中,用于相对于所述输出轴往复运动。 第一驱动37连接一个马达和用于往复驱动该输出轴的输出轴之间。 第二驱动39连接马达19和用于往复驱动该配重的配重之间。 第二驱动39优选地包括一个枢轴臂41枢转地安装在关于轴线横向于所述输出轴,用于在第一方向40在第一位置处接收的往复输入和用于在第二位置制造在第二方向上往复运动的输出42种不同的 从所述第一方向。 第一和第二驱动器提供了一个紧凑的,低振动,比较简单,平衡重传动系统用于锯。
