Embodiment Construction

[0021] like figure 1 As shown, an electric steering gear based on ball worm gear transmission in this embodiment includes a housing, a drive motor 101 , a worm gear mechanism and a steering gear output shaft 110 .

[0022] The shell is a T-shaped shell, which includes an upper end cover 107 and a lower base 112; the bearing seat upper body and the bearing seat lower body of the tapered roller bearing are integrally formed on the upper end cover 107 and the lower base 112 respectively; the inside of the shell A mechanical limit is also integrally formed, and the mechanical limit is located on both sides of the fan-shaped worm wheel 109 of the worm gear mechanism, so as to limit the rotation angle of the fan-shaped worm wheel 109 . An angle potentiometer 106 for monitoring the rotation angle of the steering gear output shaft 110 is provided in the housing just above the steering gear output shaft 110, so as to monitor the rotation angle of the steering gear output shaft 110 in r...

Abstract

The invention discloses an electric steering engine based on ball worm and gear transmission. The electric steering engine comprises a shell, a driving motor, a worm and gear mechanism and a steering engine output shaft. The worm and gear mechanism comprises a worm in transmission connection with a rotating shaft of the driving motor and a worm gear in transmission connection with an output shaft of the steering engine. The invention solves the problem that the steering engine cannot meet the accurate control requirement of the underwater vehicle in China due to low efficiency, large volume, high noise and heating, and has the advantages of low vibration, low dead weight, high efficiency, low noise and long service life.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to a low-noise and high-efficiency electric drive steering gear based on ball worm gear and worm drive. Background technique [0002] The steering gear is an important part of the underwater vehicle control system, and it is also an important source of submarine noise. Reducing the noise of the steering gear is an important way to improve the stealth performance of the underwater vehicle. At present, most underwater vehicles use gear transmission systems or hydraulic transmission systems. The above two systems have complex structures and occupy a large volume. At the same time, there are also problems of high noise and oil leakage, which are extremely important for the concealment of underwater vehicles. Disadvantage; at the same time, the complex structure and processing errors may cause the response speed and transmission accuracy to fail to achieve the ex...
