Deep sea pressure compensation type oil-filled motor based on leather bag structure

Abstract

The invention relates to a motor, in particular to a deep sea pressure compensation type oil-filled motor based on a leather bag structure, which comprises a cylindrical front cabin body and a cylindrical rear cabin body which are connected through a flange connecting block. A front end cover is arranged at the front end of the front cabin body, a through hole is formed in the center of the frontend cover, and an output shaft is step-shaped and installed in the through hole in the center of the front end cover. An oil filling port, an exhaust port and a cable interface are formed in the sideface of the rear cabin body, and a rear end cover is arranged at the rear end of the rear cabin body and is in a through circular truncated cone shape. A rubber leather bag is in a hemispherical shellshape with a flange face and is connected and fixed between the rear cabin body and the rear end cover through bolts. A compression spring is arranged between the rubber leather bag and a rear gland;the motor is arranged in the front cabin body; the motor shaft is connected with the output shaft through a set screw; and the motor, a driving plate and a watertight connector are connected throughvoltage-withstanding wires. The motor is more stable during starting and running, and has better sealing performance at a high rotating speed.

Description

Technical field [0001] The invention relates to a motor, in particular to a deep-sea pressure compensation type oil-filled motor based on a bladder structure. Background technique [0002] The deep sea generally refers to the sea area with a water depth of less than 500 meters. Due to the limitation of technical means, human exploration and understanding of the deep sea are still very limited. The deep sea environment has the characteristics of high pressure, low temperature, and no light, so it creates unique biological and material resources. Sampling research on deep-sea macrobiology, microorganisms, sediments, pore water, etc. not only helps humans understand the origin and evolution of life on earth, but also has important significance for the development of geophysics and marine geology. The actions of various sampling devices in the deep sea environment, such as drilling down, valve opening and closing, etc., require power. In the existing research, most of the existing r...

Problems solved by technology

In practical applications, due to the high-pressure dynamic sealing problem at the output shaft of the motor, the former structure generally does not exceed 3,000 meters in depth, so the latter structure is mostly used in large-depth sampling devices at present, but the latter structure is now The problem in existing technology is that in actual work, seawater may seep into the interior and cause a short circuit
