Background
The oil-cooling three-in-one new energy reducer is mainly used for cooling the stator and rotor of a motor. Meanwhile, a strand of lubricating oil is provided for assisting lubrication of a bearing or a differential gear with poor splash lubrication in the speed reducer. The active lubricating system mainly comprises an electronic oil pump, a heat exchanger, an oil pipe and an oil duct designed in a shell structure. The electronic oil pump absorbs oil, and the oil enters the heat exchanger for cooling through an oil pipe or an oil duct designed in the shell, so that the lubricating oil at the temperature of about 110 ℃ is cooled to about 85 ℃. And the cooled lubricating oil is guided to the stator and the rotor of the motor to be cooled through an oil duct designed in an oil pipe or a shell.
The oil duct designed in the shell structure is formed by connecting and communicating a plurality of sections of intersected straight hole oil ducts in the machining process of the shell. And installing an oil plug at a required port position. Isolated from the external environment to form a relatively closed lubricating oil path. Therefore, the simpler the oil channel design is in the shell structure, the fewer the oil channels are, the smaller the pressure drop of the active lubricating oil is, the fewer the oil plugs are installed, and the smaller the risk of oil leakage at the oil plugs is. When the oil duct of the existing oil-cooled three-in-one new-energy speed reducer is arranged, the shape and the structure of the shell of the speed reducer are always the same and the hole is convenient to open, and a long tortuous oil duct is often formed by intersecting too many straight-hole oil ducts, so that the oil leakage risk is increased, and the oil blockage is increased.
