DRIVEN TOOL WITH FRICTION COUPLING Russian patent published in 2013 - IPC B25B21/00 B25B23/00 B25B23/157 F16D13/38 

FIELD: process engineering.

SUBSTANCE: invention relates to driven tool with friction coupling. Proposed tool comprises handle, drive section with output shaft, end adapter section designed to retain end adapter, and friction coupling. Friction coupling is arranged between end adapter section and drive section. Friction coupling comprises drive part to rotate along with drive section that has contact surface of drive side and driven part coupled with end adapter section and having contact surface of driven part that can get in contact with drive side contact surface. On application of pressing force by end adapter handle gripped by the user to machined part friction between drive side contact surface and driven side contact surface is increased for end adapter to rotate.

EFFECT: adjustment of friction, decreased noise.
