Description
technical field [0001] The invention relates to the technical field of hydraulic oil cylinders and motion control thereof, in particular to an oil injection system for an annular oil cylinder. Background technique [0002] The advantages of hydraulic transmission are: high power, high efficiency, low noise, safe and stable, highly integrated, etc. At present, the commonly used hydraulic transmission method is to drive the hydraulic pump to rotate through the motor, absorb oil from the fuel tank, and connect a series of hydraulic valves after the pressure oil is output from the hydraulic pump, and then connect to the work piece. By controlling the working state of the hydraulic valve, the actuator realizes the requested action. This kind of transmission mode is difficult to meet the situation that the working part of the oil cylinder needs to have rotary motion. In the design of CNC boring and milling machine for processing wind turbine hubs, an annular oil cylinder is requ...
