Title
(EN) Single shaft yaw electric bolt-tightening machine
Abstract
(EN)

A single-shaft yaw electric bolt-tightening machine, comprising a base (1), a bracket (2), an electric tightening shaft assembly (14), a sleeve (15), a reaction force supporting board (16), a dedicated sleeve (17), a reaction force sleeve (18), a servomotor (19), a torque sensor (20), an angle sensor (21) and a connecting shaft (22). The bracket (2) is fixed on the base (1) and is provided with a rotary servomotor (3) and an encoder (4). The rotary servomotor (3) is connected with an output shaft (5) which is provided with a small pulley (6). The small pulley (6) is fitted with a big pulley (8) by a toothed belt (7). The big pulley (8) is connected with a rotating shaft (9). A guide rod (12) is connected with a rotating arm (10) by a shaft sleeve (11) and is fixed on a cover-plate bracket (13) in which the electric tightening shaft assembly (14) is fixed.
