1results about How to "Smooth oil return" patented technology

This invention discloses a torque balancing device and an oil supply and return system, belonging to the technical field of submersion motion test equipment. The torque balancing device is installed on a submersion motion test bench, which includes a column, a platform located inside the column, a crossbeam fixed to the top of the column, and a lifting actuator fixed above the crossbeam. The movable end of the lifting actuator is connected to the platform. The torque balancing device is located between the column and the platform. It is used to counteract the overturning torque caused by the control error of the lifting actuator and the overturning torque caused by a malfunction in the control system of the submersion motion test bench, thus enabling the platform to move vertically along the column. The torque balancing device includes a torque balancing cylinder, a ball joint, and a hydrostatic support plate. The torque balancing cylinder is fixed to the corner beam of the platform, and the hydrostatic support plate is attached to the surface of the column. The piston rod of the torque balancing cylinder is connected to the ball head of the ball joint by screws, and the ball socket of the ball joint is connected to the hydrostatic support plate by screws.
