The invention discloses an electromagnetic tensioning
system suitable for a
piston engine aircraft
transmission system, and relates to the technical field of tensioning mechanisms, the electromagnetic tensioning
system comprises a first fixing seat, a
pressure sensor, an electromagnetic driving mechanism, a tensioning execution mechanism and a second fixing seat; the electromagnetic driving mechanism comprises an
electromagnetic coil, an iron core, a telescopic guide cylinder and a telescopic guide cylinder fixing piece, the telescopic guide cylinder fixing piece is fixed to the first fixing base, the telescopic guide cylinder penetrates through the telescopic guide cylinder fixing piece and abuts against the
pressure sensor, the
pressure sensor is arranged between the telescopic guide cylinder and the first fixing base, and the iron core is fixed in the telescopic guide cylinder; the
electromagnetic coil is sleeved on the iron core; the tensioning executing mechanism comprises an actuating sleeve and a permanent
magnet armature, the actuating sleeve is arranged outside the telescopic guide cylinder in a sleeving mode and fixedly connected with the second fixing base, and the armature is fixed to the actuating sleeve and arranged opposite to the iron core. The
system is high in response speed, can achieve the precise control of the tensioning force, better meets the
space requirements of a helicopter
transmission system, and is low in maintenance cost.
