SCREW APPARATUS AND MANUAL SCREW SYSTEM Russian patent published in 2021 - IPC B25B13/48 B25B17/00 B25B23/142 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a screwing apparatus configured to apply torque to a screw unit (12) and to a manual screwing system. The apparatus is comprised of a body containing an outlet unit (10) made with a gear reversibly coupled with the screw unit (12), an inlet unit (20) with a section for intake of driving torque by manual or mechanical impact, and devices for recording the outlet torque applied to the screw unit from the outlet side. The outlet torque recording devices (48) are mounted on and/or in the body in form of recording devices (48), said torque recording devices configured to record axial impact applied to the helical gear (38) which connects the inlet unit (20) and the outlet unit (24) with application of torque, said gear configured to rotate around the rotation axis (52) and to supply it for preferably electronic estimation of the signal, wherein the recording devices constitute devices (48) including a pressure and/or impact detector, the devices being coordinated with the helical gear (38) with force closure and with axial closure based on the body side (30) of the body.

EFFECT: improved screwing apparatus for applying torque to a screw unit.
