Abstract

The present invention relates to a microturbine generator, comprising: ① micro pneumatic turbine: including a cavity, a turbine, and an upper baffle; the cavity and the upper baffle form a gas passage; ② micro generator: including a stator and a rotor; Composed of circuit board and stator yoke, the stator yoke is embedded in the lower end cover, the coil is processed on the flexible circuit board, and the flexible circuit board is attached to the exposed side surface of the stator yoke: the rotor is composed of the rotor yoke, the rotor base plate and the permanent magnet Composition; ③ transmission device: including rotating shaft, upper bearing and lower bearing; the fixed connection between the turbine and the rotating shaft, and the fixed connection between the rotating shaft and the rotor; ④ housing: the rotating shaft is connected to the upper end cover of the housing through the upper bearing, and the It is connected with the lower partition of the casing, and plays the role of fixing the rotating shaft and transmitting the power of the rotating shaft. The invention is suitable for the power supply device of the bullet fuze of the artillery sub-communication ammunition and other equipments requiring the miniature power supply device.

Description

technical field [0001] The invention relates to a microturbine generator, which is suitable for the power supply device of the bullet fuze of artillery sub-communication ammunition and other equipment requiring a micro power supply device, and belongs to the field of micro motors. Background technique [0002] The bullet fuze of my country's existing artillery sub-munitions is small in size and does not have enough space to install a power supply unit, so a mechanical trigger fuze is used. The mechanical trigger fuze uses a needle firing mechanism, and its disadvantage is that it is difficult to improve the reliability of firing due to the influence of mechanical structure characteristics, which is manifested in a high misfiring rate of bullets (about 5%). Under the international background that many countries in the world propose to limit the use of sub-munitions, it is particularly important to reduce the misfire rate of sub-munitions. [0003] An important way to reduce ...
