VIBRATING NUTRUNNER

摘要

The present invention relates to a vibrating nutrunner that comprises the following members: a body (1) with a control handle (2); an actuator (3) arranged in said body and provided with an output shaft (4); and a rotary vibration generator which is connected to the output shaft and consists in a pair of flywheels (6, 7) connected together by a mechanism (7) with variable rotation speed as well as by a planetary reducing gear (8). The carrier (14) of the planetary reducing gear (8) is connected directly to the mandrel (15) of the nutrunner, wherein said mandrel comprises a head to receive a wrench at the end thereof. The flywheel (6) of the rotary vibration generator which is arranged on the side of the planetary reducing gear (8) includes a braking mechanism (16).
