    摘要： A multi-speed, power-driven tool may include a transmission 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.

    摘要： A power tool includes a housing; an electric motor; an electronic clutch; and a clutch setting assembly that includes a variable resistive element, a clutch selector, and a contact assembly. The contact assembly includes a spring coupled to the clutch selector and a contact member with a leg configured to be insertable into an opening in the clutch selector so that the spring and the contact member are non-removable from the clutch selector and the spring biases the contact member against the variable resistive element. The contact member has a head configured to engage the variable resistive element to generate a resistance signal that corresponds to a position of the clutch selector. The controller is configured to receive the resistance signal and, based on the resistance signal, look-up, receive, or generate the torque threshold value for the power tool operation parameter that corresponds to the selected clutch setting.

    摘要： A power tool having one or more sound damping members which reduce sound and/or vibration from one or more parts of a power tool. The sound damping member can reduce sound and/or vibration from static or dynamic parts of a power tool. The sound damping member can reduce noise and/or vibration from one or more rotating or moving parts of a power tool and its housing or internal structure. Methods, means, controls, systems and practices for reducing or eliminating undesired sound from a power tool are disclosed.
