摘要： A tool having a housing assembly, which defines a handle, a motor assembly, a trigger assembly, a spindle and a transmission assembly. The motor assembly is received in the housing assembly and has an output shaft. The trigger assembly is coupled to the housing assembly and is configured for use in actuating the motor assembly. The transmission assembly transmits rotary power between the output shaft of the motor assembly and the spindle. The transmission assembly includes a planetary stage with an input sun gear, an output planet carrier and a compound planet gear having a first planet gear and a second planet gear coupled together for common rotation on the output planet carrier. The planetary stage is selectively operable in a first gear reduction and a second, relatively lower gear reduction in which the compound planet gear cooperates to produce at least one intermediate gear reduction within the planetary stage.

摘要： A force and moment canceling reciprocating mechanism for a power-driven tool may include a transmission including an input gear assembly and an output gear assembly, coupled to a reciprocating mechanism. The input gear assembly may include a first input gear coaxially aligned with a second input gear. The output gear assembly may include a first output gear coaxially arranged with a second output gear. The reciprocating mechanism may be coupled to the output gear assembly, to convert rotational motion to linear motion, for output to an output accessory of the tool. One or both of the first and second input gears may include counterweights, or counterweight masses, and one or both of the first and second output gears may include counterweights, or counterweight masses. The counterweighting of the input and output gear assemblies may provide for the cancelation of forces and moments generated by the operation of the motor and the transmission, and the reciprocal motion of the reciprocating mechanism.

摘要： A clutch for a power tool includes an adjustment ring configured to move axially relative to the housing while being rotated relative to the housing. A spring retainer is disposed axially rearward of the adjustment ring. The spring retainer is coupled for rotation together with the adjustment ring and configured to remain substantially axially stationary relative to the housing when rotated. A spring is disposed between the adjustment ring and the spring retainer. A clutch face is coupled to a portion of the transmission. A locking member is disposed between the spring retainer and the clutch face. The locking member is configured to transfer a holding force exerted by the spring to the clutch face. Rotation and axial movement of the adjustment ring alters the holding force exerted by the spring. When an amount of output torque exceeds the holding force, torque transmission to the output spindle is effectively interrupted.

摘要： A power-driven tool may include a clutch mechanism selectively provides for engagement between and transmission mechanism and an output mechanism of the tool. The clutch mechanism may include a variable rate, or a dual rate biasing mechanism. mechanism that transmits power from a motor to an output device. A speed selection mechanism may be coupled to the transmission mechanism, to control a speed reduction through the transmission mechanism, and an output speed of the tool. The transmission mechanism may employ a compound, stepped, planetary gear assembly, to provide for an axially compact arrangement of transmission mechanism components, to reduce an axial length of the tool. The speed selection mechanism may employ a multi-staged grounding device, corresponding to the reduced axial length of the transmission mechanism.

Each set of mating conically-shaped features includes a first cone portion and a second cone portion. The first cone portion of each set of mating conically-shaped features is coupled to the first housing component and has a frusto-conically-shaped exterior surface. The second cone portion of each set of mating conically-shaped features is coupled to the second housing component and has a frusto-conically-shaped interior surface that is engaged with the frusto-conically-shaped exterior surface of an associated first cone portion. Each fastener is received through an associated pair of the first and second cone portions and is threadably engaged to one of the first and second housing components.
