Tools for making and releasing pressurized oil pressure belts with cylindrical or conical seat surfaces, e.g. B. between shafts and gears are known in numerous types. In one design, the return oil is fed to the seat surface through a hollow screw that is screwed into the end face of the shaft. By means of a nut on an external thread of this hollow screw, the gear wheel is pushed onto the shaft via a sleeve that acts on the gear wheel or is pulled off the shaft.

The invention creates a very simple installation tool that consists of a few parts and does not require any cumbersome laying of lines, since the only pump required is connected directly to the banjo bolt. To loosen the bandage, only the pressure piston needs a hydraulic device for producing a pressure oil pressure bandage

4 -0 screw s are shown _{radially from the Leitune l} T one or more lines 15 , which lead into the cubic capacity ίο of the tool. The pressure cylinder 12 is sealed off from the pressure cylinder 13 with a sleeve 17 made of an oil-resistant material. which is held by a ring 18 on the Uruckkolbeii. Correspondingly, a sealing sleeve 19 with a retaining ring 20 is attached to the pressure cylinder 13 opposite the hollow screw S. To produce the pressure-oil compression bandage, the gear wheel 2 is first placed on the opposite surface of the shaft 1 after the usual cleaning of the seat surface 3 . The hollow screw 5 is down to the bottom

Claims (1)

screwed into the bore of the shaft 1 in a sealing manner and the pump connected to the thread 6 . The pressure oil is fed to both the seat surface 3 and the displacement 16 of the tool at the same time. As the pressure increases, the gear 2 is pushed onto its seat in a known manner and the tool is then unscrewed again. To loosen the bandage, a spacer ring (not shown) can be screwed onto a thread 21 of the pressure cylinder 13. This ring then abuts when screwing the tool to the end face of the shaft 1 and thus prevents to drove the pressure oil to move the printing cylinder 13 relative to the piston 12. The Druckül then acts only in the seat 3, so that the dressing dissolves ts and the gear 2 snaps out against the flange 14 of the printing cylinder. Claim: Hydraulic device for producing such a pressure oil interference fit with a preferably tapered seat, z. B. between a shaft and a toothed wheel, with a hydraulic tool, by which one part of the union, z. B. the gear, on the other part of the association, z. B. on the shaft, the pressure oil is fed from a line system of the seat surface between the two parts of the association, characterized in that the pressure piston (12) of the hydraulic tool is coaxial with a hollow screw containing the pressure oil supply line for the seat surface (5) is formed, the concentric firmly in one part of the association, z. B. in the shaft (1) can be screwed, while the pushable pressure cylinder (13) of the hydraulic tool one on the other part of the association, z. B. on the gear (2), acting! • 'Iansch (14), and that from the Druckölcitung (7) in the hollow screw (5) a line (15) is branched into the displacement (16) of the hydraulic tool, so that the sliding of the toothed wheel (2) and producing the oil film in the seat surface (3) of only one common Preßverbandes Drucköiqueiie, z. B. a pump is required, which can be directly connected centrally to the hollow screw (S) of the tool. In addition 1 Biafc drawings 509 660/73 J. 65 OBundcsdnickcrciDerlin
