    • A reciprocating saw includes a housing assembly and a motor positioned substantially within the housing assembly. The motor includes a pinion. A drive mechanism is positioned substantially within the housing assembly and includes a gear driven by the pinion, a spindle, and a connecting rod to transmit rotation of the gear into reciprocation of the spindle. A bushing is positioned substantially within the housing assembly about at least a portion of the spindle. The bushing is pivotable relative to the housing assembly to accommodate non-linear rocking motion of the spindle. A seal surrounds a portion of the bushing and includes a first lip extending radially from the bushing and a second lip spaced apart from the first lip and extending radially from the bushing. The second lip is movable relative to the first lip. Both the first lip and the second lip continuously engage the housing assembly when the bushing pivots relative to the housing assembly.
    • 往复锯包括壳体组件和基本上位于壳体组件内的马达。 马达包括一个小齿轮。 驱动机构基本上位于壳体组件内,并且包括由小齿轮驱动的齿轮,心轴和连接杆,以将齿轮的旋转传递到心轴的往复运动。 衬套围绕主轴的至少一部分基本上位于壳体组件内。 衬套相对于壳体组件可枢转以适应主轴的非线性摇摆运动。 密封件围绕套管的一部分并且包括从衬套径向延伸的第一唇缘和与第一唇缘间隔开并从衬套径向延伸的第二唇缘。 第二唇缘相对于第一唇缘是可移动的。 当衬套相对于壳体组件枢转时,第一唇缘和第二唇缘都连续接合壳体组件。
