Abstract

Research on a type of non-contact driver made of magnetic materials in a rope drum was carried out to solve the problem of leakage in the deep dynamic seals of motor output shafts. An isolation sleeve was added between the inner and outer magnetic rotor, which changed the sealing type from a dynamic seal located on the motor output shaft to a static seal on the front end; this allows the sealing depth to go down more than 10000 m. This study designed the driver components, analyzed the principle of magnetic coupling, and used the method of finite elements to analyse the intensity of the sleeve. Through the rope drum sealing pressure test and the pulling rope experiments at sea, its sealing pressure can reach up to 110MPa. Research verified the effectiveness of the sealing, rotational stability, tensioning reliability, and engineering feasibility.
