Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] refer to Figure 1 to Figure 6 As shown, the integrated propulsion and power generation device based on shaftless counter-rotating wheel rim drive in an embodiment provided by the present invention includes a conduit, and two runner assemblies are sequentially arranged in the conduit along the axial direction of the conduit, and the two runners The components are respectively connected with the motor and the generator;

[0027] Among them, the runner assembly includes a stator, a rotor, and a propeller that are sequentially sleeved in the conduit. The stator is connected to the conduit and fixed, and the two ends of the rotor are installed on the conduit through bearings. The propeller rotates with the rotor. The two runner assemblies The propellers rotate in opposite directions.

[0028] Further, the stator is sleeved on the inner wall of th...

Abstract

The invention discloses an integrative propulsion and power generation device driven by axis-free contra rotating wheel flanges. The device comprises a guide pipe, and the guide pipe is internally provided with two rotating wheel assemblies which are axially and sequentially arranged along the guide pipe; each rotating wheel assembly comprises a stator, a rotor and a propeller which are sequentially arranged in the guide pipe in a sleeved mode, the stators are fixedly connected with the guide pipe, the two ends of each rotor are arranged on the guide pipe through bearings, the propellers rotate along with the rotors, and the rotating directions of the propellers in the two rotating wheel assemblies are opposite to each other. The integrative device is compact in structure, high in formed power density and thrust-weight ratio, long in service life, low in vibration noise and especially suitable for application to unmanned underwater vehicles, propulsion and power generation are conducted synchronously, the energy utilization rate is increased, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to an integrated device for propulsion and power generation based on shaftless counter-rotating rim drive. Background technique [0002] With the development of advanced ship technology, various high-performance ships have higher and higher requirements for their propellers. For example, cruise ships require propellers with high speed and low noise, submarines require propellers with low noise and hope to solve the problem that the propulsion shaft passes through the pressure compartment In order to solve the problem of high cost, submarines require propellers to be highly efficient and energy-saving. The inherent structural restrictions of traditional shafting propellers are increasingly unable to meet the requirements, and shaftless rim-driven propellers have emerged as the times require. It integrates the motor-propeller-water-lubricated bearing, cancels the traditional s...
