Abstract
The invention provides a device and method for fastening and loosening threaded fasteners. Therefore, threaded fasteners, narrow and located at the special positions, are unnecessarily screwed up by a hand-operated spanner. A non-hand-operated spanner, such as a pneumatic impact wrench, is utilized for fastening threaded fasteners at any position. Therefore, labor time is decreased, working efficiency is increased and labor cost of an enterprise is lowered. The device comprises a housing, an input gear, an idle pulley, an output gear and thrust bearings. The multiple thrust bearings are arranged in the input gear, the idle pulley and the output gear and then arranged on a first housing. Then, the multiple thrust bearings are arranged on the other end of the input gear, the idle pulley and the output gear, and then buckled with a second housing. Finally, two housings are fixed. When the threaded fasteners need fastening, an output end of the pneumatic impact wrench drives the input gear of the device. The input gear drives the idle pulley and the idle pulley drives the output gear. The output gear drives a sleeve to screw up the threaded fasteners. The threaded fasteners are loosened and reversely rotate.
