Problems solved by technology

[0002] The thruster is the power source of the underwater machine. There are many problems in the existing underwater thrusters. Firstly, in order to increase its reliability in deep water, the thickness of the shell is often increased, which makes the thruster extremely heavy; secondly, the traditional The structural reliability of the O-ring seal arranged on the reducer shaft is low, and the loss to the reducer is large; then the magnetic coupling mechanism can solve the wear problem, but the technology is not yet mature, and the output torque loss is large; finally, the underwater propeller motor often needs to be overloaded The traditional sealing structure will trap the heat generated by the motor inside the propeller, causing the motor to overheat and affect the performance of the motor, thereby reducing the efficiency of the entire propeller

Abstract

The invention provides an oil seal underwater propeller and belongs to the field of underwater propellers. The oil seal underwater propeller comprises a propeller body and a compensator and further comprises an oil pipe, a head cover, a propeller oil pipe fixing sleeve, a shell, an oil seal gland, an oil seal outer retainer ring, an output shaft, a propelling screw, a sacrificial anode, an air deflector, an air deflector supporting rod, a skeleton-type oil seal, a speed reducer, a motor, a piston cylinder, a piston cylinder seat, a compensator oil pipe fixing sleeve, an oil pipe plug and an oil sac, the propeller body and the compensator are connected through the oil pipe, the head cover, the shell, the oil seal gland, the oil seal outer retainer ring and the output shaft are connected sequentially and matched with the skeleton-type oil seal to form a propeller sealing member, the air deflector is fixedly connected with the shell through the air defector supporting rod, and the propelling screw and the sacrificial anode are mounted the output shaft. The oil seal underwater propeller has the advantages that the problem of wearing of the propeller can be improved, reliability of a sealing structure can be improved, thickness of the shell of the propeller can be reduced, the problem of heat radiation of the motor can be solved, and loss of torque transmission can be avoided.
