Electrically powered tool

Abstract

A power tool such as a portable cutting machine has less gear noise from, for example, a reduction gear train under no load. The power tool includes a blade, an electric motor including a motor shaft, and a gear train that transmits a rotational output from the electric motor to the blade. The gear train includes a first gear supported on the motor shaft, a countershaft, an intermediate gear meshing with the first gear and supported on the countershaft, a final shaft having a distal end attached to the blade, a final gear meshing with the intermediate gear and supported on the final shaft, and at least one elastic member between the final shaft and the final gear.
