Deep-sea high-power low-vibration motor direct-drive propelling device

Abstract

The invention provides a deep-sea high-power low-vibration motor direct-drive propelling device, which comprises a propeller, the propeller is fixedly connected with a propelling motor through a guide pipe fixing flange cap, a sound insulation cover is installed outside the propelling motor, and a vibration isolation sealing gasket is installed between the sound insulation cover and a flange of the propelling motor. Meanwhile, a first vibration isolation ring and a second vibration isolation ring are arranged between the sound insulation cover and the propulsion motor; the output end of the propelling motor is connected with a rotating shaft through a crowned tooth coupler, a propeller sealing vibration isolation mechanism is installed on the rotating shaft, a propeller is installed on the head of the rotating shaft, and an oil filling quick-change connector is further arranged on the guide pipe fixing flange cap. In the rotating process of the propeller, the sealing problem of a large-diameter shaft penetrating cabin in a deep sea can be solved, vibration of the propeller transmitted to a motor and a bathyscaph shell is reduced, the underwater radiation noise value of the high-power motor and the high-speed rotating propeller is effectively reduced, and the service life of the propeller is prolonged. The support of the large-diameter shaft cabin-penetrating sealing and sound stealth technology is provided for the large bathyscaph.

Description

technical field [0001] The invention relates to the technical field of deep-sea propulsion devices, in particular to a high-power low-vibration motor direct-drive propulsion device for deep sea. Background technique [0002] In the propulsion device of deep-sea vehicles, the motor is generally used to directly drive the propeller to design and manufacture. At present, the size of deep submersibles at home and abroad is not large, so the power of the motor of the propulsion device is not large, and the noise of the propeller The indicators are not too demanding, and the problem of vibration and noise is easy to solve. Because the power of the propulsion device is small, the shaft diameter of the cabin is small, so the sealing is also easy to solve. However, if the deep submersible is large, the power of the propulsion device is large, the shaft diameter of the cabin is large, the speed of the propeller is high, and the requirements for concealed navigation are high, the high...
