I am searching for a practical factory-made hydraulic cylinder (actuator) that can provide an axial push of 140 kN against the shaft of the rotor of an electric generator and also transmit the 90 kNm torque from the motor to the shaft of the generator (see Fig. 1).
Fig. 1. Electric generator rotated by a motor and pushed by a hydraulic cylinder.
Explanations: The generator is an experimental submerged electric machine of a special construction supposed to be rotated by an underwater turbine mounted on its shaft, in front of the generator. This turbine rotates at about 60 RPM providing a 90 kNm useful torque. Unfortunately, it also pushes against the generator with 140 kN. For testing purposes, the generator will be rotated first with an electric motor which I found. However, it only simulates the torque of the turbine. The thrust has to be generated with a hydraulic cylinder that I have not found.
Question: Are there hydraulic cylinders (like the one in Fig. 1 or of a different construction) that provide thrust and at the same time transmit rotary motion from a motor to a generator?
Even cylinders that can generate 14 or 7 kN of thrust would be useful for the beginning.
Remark: I have found rotating hydraulic cylinders (pistons), like in Fig. 2, but they can provide push to the motor itself if mounted in front of it. They can also supply thrust to the generator but in this case the shaft between the generator and the hydraulic cylinder needs a cogged wheel on it that has to be rotated by another one on the shaft of the motor. The setup is complicated.
