Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship steering engine technology, in particular to a steering engine transmission mechanism. BACKGROUND

[0002] The ship steering engine is the core equipment for controlling the ship's heading, and the performance of its transmission mechanism is directly related to the safety and control accuracy of the ship's navigation. The traditional ship steering engine transmission mechanism has many shortcomings: although the pure electric drive has high control accuracy, the transmission parts are easily affected by water impact or instantaneous overload during steering, which leads to problems such as wear and tear, breakage, and poor long-term reliability due to the lack of effective buffer protection; although the pure hydraulic drive has certain buffer capacity, it has the defects of slow response speed and low angle control accuracy, and the risk of hydraulic oil leakage threatens the safety of operation. At the same time, some mechanisms use a single transmission structure, which can easily cause the steering engine shaft to be stuck once the drive component fails, making it impossible to achieve emergency steering; the traditional worm and gear transmission is prone to radial force due to design problems, increasing the load on the steering engine shaft, and long-term use may cause shaft deformation. In addition, the existing detection mechanism often has detection errors due to insufficient coaxial installation, and lacks a real-time feedback mechanism, making it difficult to ensure steering accuracy; in severe sea conditions, the steering engine shaft is easily subjected to excessive stress when subjected to sudden impact due to the lack of targeted buffer and overload protection design, reducing the service life of the equipment and even causing chain failures. Therefore, the development of a steering engine transmission mechanism that integrates efficient drive, accurate detection, reliable buffer, and redundant protection functions has become a key to meeting the high-precision, high-stability, and high-safety requirements of modern ship heading control.
