Adopt above linkage structure, during installation, first drive flange is fixed on the end face of power take-off, drive sleeve is enclosed within on the main shaft of oil hydraulic pump, right hole and the oil hydraulic pump main shaft of drive sleeve link together by spline or flat key, again oil hydraulic pump is nested in the drive flange, the left hole of drive sleeve and the main shaft of power take-off are linked together by spline or flat key, at last oil hydraulic pump is fixed on the end face of drive flange, realized so coaxial the linking to each other of oil hydraulic pump main shaft of power take-off main shaft with the oil hydraulic pump of power take-off, thus the stable delivery moment of torsion.
On described drive flange (3) and power take-off (1) and surface of contact that oil hydraulic pump (2) is connected, all offer seam (5), be further defined by the coaxality of seam to drive flange and power take-off, drive flange and oil hydraulic pump, make the pressure transmission more stable.
In order to limit moving axially of drive sleeve, radially offer radial hole (4c) on the described drive sleeve (4), be equipped with in this radial hole (4c) and press closer screw (6), the described end that presses closer screw (6) is connected on the outer surface of power take-off main shaft (1a) or oil hydraulic pump main shaft (2a), and this presses closer screw (6) by locking nut (7) locking that is positioned at drive sleeve (4) outer surface.
Reveal for the gear oil that prevents power take-off, on the surface of contact that described drive flange (3) and power take-off (1) and oil hydraulic pump (2) connect, all be equiped with O RunddichtringO (8).
Beneficial effect: the utility model uses drive flange that oil hydraulic pump and power take-off are linked together, adopt simultaneously seam to guarantee three's coaxality, use drive sleeve that oil hydraulic pump main shaft and power take-off main shaft are linked together, make delivery pressure stable, also have the advantages such as processing technology is simple, easy for installation, low cost of manufacture.
