Abstract
Official abstract text for this publication.
An electric power tool includes a housing, a motor disposed in the housing, a planetary gear reduction mechanism and an internal gear. The planetary gear reduction mechanism includes multi-stage planetary gears, multi-stage carriers each configured to carry a plurality of planetary gears, and a bearing assembled with a final-stage carrier from a rear side of the final-stage carrier to rotatably support the final-stage carrier. The internal gear is configured to be rotatable and axially slidable while allowing planetary motion of final-stage planetary gears supported by the final-stage carrier. A gear portion provided on the final-stage carrier is formed as a separate gear which is assembled with the final-stage carrier from the rear side of the final-stage carrier after assembling the bearing with the final-stage carrier.
First claim
Opening claim text (preview).
What is claimed is: 1. An electric power tool comprising: a housing; a motor disposed in the housing; a planetary gear reduction mechanism positioned at a front side of the motor and including: multi-stage planetary gears, multi-stage carriers arranged in an axial direction of the motor, each multi-stage carrier being configured to carry a plurality of planetary gears, a bearing assembled with a final-stage carrier so as to rotatably support the final-stage carrier, and…
