  • Nowadays, a vapor cycle refrigerant system of a helicopter mainly comprises a compressor, a medium-frequency motor, an evaporator, a condenser, an evaporation fan, a condensing fan and an expansion valve. Motion transmission of the medium-frequency motor is achieved by a belt so as to drive the compressor to realize refrigeration. This method of driving the compressor has the following disadvantages: 1) motion transmission by using a belt occupies a large area of spaces and requires good positioning of the components and high precision with respect to installation; 2) the motor has an independent cooling mechanism which requires additional cooling fan and air ducts etc. to be provided, thereby resulting in undesirable bulkiness and heaviness; 3) tension of the belt and its limited service life requires additional maintenance and replacement. A hermetically sealed refrigerant compressor may effectively solve the above problems. However, a hermetically sealed refrigerant compressor according to prior art generally has a start current 5-7 times stronger than a working current. In an on-board device, such a strong start current will trigger power protection of the helicopter and thus causes power failure which is dangerous.

The device comprises only a sun gear fixed directly to the shaft and rotatable planet gears carried by the rotor hub and meshing with the sun gear, the planet gears being individually unbalanced but arranged symmetrically with respect to the axis of the shaft so that the gearing as a whole is always in balance.
