FIELD: machine building.
SUBSTANCE: invention relates to power take-off mechanisms. Power take-off (PTO) comprises a cover-equipped pneumatic chamber made from a housing in the form of a bushing. Inside the bushing there is a piston with possibility of movement, which is connected by means of a screw on one side with a rod made stepped along the outer surface and equipped with an elastic element. Second end of the rod is connected to the guide bushing fixed in the hole of the hollow housing. Fork installed on the rod has the possibility of contact with the hub of the drive gear fixed on the driven shaft with the possibility of movement. Both ends of the driven shaft are installed in bearings. Besides, in the hollow housing the ends of the axis are fixed, on which the drive gear is fixed. According to the first version: The PTO is equipped with a spacer and the output shaft of the PTO is equipped with a hole with a key slot. According to the second version, the output shaft of the PTO is equipped with splines and a flange.
EFFECT: increasing power take-off of the operating engine, variability of the installation.
