POWER TOOL WITH MULTISPEED TRANSMISSION

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...

Beschreibung
Zusammenfassung:	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.
