Abstract

The invention discloses a deep-sea motor based on magnetic coupling transmission and a transmission method. The deep-sea motor based on magnetic coupling transmission comprises a non-magnetic pressure-resistant shell and a magnetic coupling motor; the pressure-resistant shell comprises a body and a cover body, and the magnetic coupling motor comprises a driving assembly and a magnetic coupling output rotor shaft; and a containing cavity is formed in the body, the cover body comprises a cover plate and an inner barrel part protruding towards the inner side face of the cover plate, the magnetic coupling output rotor shaft is installed in the inner barrel part through a bearing, the driving assembly is installed in the containing cavity, the body is covered with the cover plate in a sealed mode, and the magnetic coupling output rotor shaft is in transmission connection with the driving assembly in a magnetic coupling transmission mode. The deep-sea motor based on magnetic coupling transmission does not need a sealing element to carry out dynamic sealing on the output shaft, and the problems of oil leakage and dynamic sealing of the rotary output shaft are solved.

Description

technical field [0001] The invention relates to the technical field of submersible motors, in particular to a deep-sea motor and a transmission method based on magnetic coupling transmission applied in a deep-sea environment. Background technique [0002] The oil-filled balanced underwater motor is commonly used in the existing deep-sea motors, and the oil-filled balanced motor has a simple structure and is easy to implement. The balance modes of the oil-filled balanced underwater motor include membrane compensation, oil bladder compensation and piston compensation; the principle is that the protective shell of the deep-sea motor is filled with oil, and the deformation under high water pressure passes through its compensation membrane, oil bladder or compensation piston. A method of deformation to achieve pressure equilibrium. For example, an invention patent of Patent No. 2012102389458 "Controller Integrated Deep Sea Motor" utilizes a similar pressure balance device. [0...
