The invention discloses an oil-immersed hydraulic power source system for an aircraft undercarriage. The system comprises an oil tank and a motor assembly, the motor assembly is fixedly installed in ashell, the shell is fixed to the bottom of the oil tank, an oil inlet communicated with the oil tank is formed in the top of the shell, and a power interface for supplying power to the motor assemblyis installed on one side outside the shell; a sealing piece used for being connected with a pump assembly is installed at a driving end of the motor assembly, an oil return assembly is further connected to the side, away from the sealing piece, outside the shell, an oil outlet of the oil return assembly is communicated with the interior of the shell, and the oil tank is filled with hydraulic oil.The motor assembly and the oil tank are integrally designed, space can be effectively saved, and leakage during oil supply can be effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of aviation hydraulic power sources, and in particular relates to an oil-immersed hydraulic power source system for aviation landing gear. Background technique [0002] During the process of retracting and extending the landing gear of the aircraft, a hydraulic power source is required to provide stable power. However, the current hydraulic power source used in the landing gear is a split design. The oil tank and the motor are set separately. It occupies a large space, and when the hydraulic pump is rotating, the hydraulic oil will leak due to the failure of the dynamic seal, causing long-term problems such as oil leakage, oil leakage, oil dripping, and oil leakage in the aircraft hydraulic power source system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-immersed hydraulic power source system for aviation landing gear, which takes up ...
