摘要： A reciprocating saw including a housing, a spindle mounted for reciprocating motion within the housing, a gear rotatably mounted within the housing, a wobble shaft rotatably mounted within the housing, a wobble plate rotatably mounted on the wobble shaft and connected to the spindle, and a clutch drivingly connecting the gear to the wobble shaft. The clutch includes a clutch driver rotatably positioned within the housing adjacent the wobble shaft, and the clutch driver includes a recess for insertably receiving a portion of the wobble shaft. The clutch driver can also include a relief ledge for providing clearance between the clutch driver and the wobble plate. The clutch can further include a first clutch disk connected with the gear and positioned between the gear and the clutch driver, and a second clutch disk connected with the clutch driver and positioned between the gear and the first clutch disk.

摘要： An inflatable flexible gland clutch has a gland secured to one of a pair of cooperating clutch elements. The gland mounts friction shoes and includes inflatable chambers which, when subjected to air under pressure, will move the gland to a position where the shoes engage the other clutch element. Other chambers formed in the gland will, when inflated, disengage the clutch by moving the clutch shoes away from engagement with the mating clutch element.
摘要翻译：一种可充气的柔性密封离合器具有固定到一对配合的离合器元件之一的压盖。压盖安装摩擦鞋，并且包括可充气室，当压力下受到空气时，其将使压盖移动到鞋与其它离合器元件接合的位置。形成在压盖中的其它室将在膨胀时通过使离合器鞋离开与配合离合器元件的接合来使离合器脱离。
