鱼雷定深仪差动式机械限位器结构分析

针对目前鱼雷航行深度遥控定深仪对鱼雷的航行深度标定进行机械限位的要求，分析了鱼雷航行深度遥控定深仪中差动式机械限位器的结构和原理，从该机构在结构设计中采用的类蜗轮蜗杆传动方式出发，进一步通过对该机构的运动学分析和数学建模，定量地描述了特征零件的运动姿态和轨迹，分析了影响限位位置的特征零件的主要参数，结果表明，该机构能够满足鱼雷定深标定机械限位的要求。该研究可为类似限位装置的设计和应用提供一定的参考。

Differential Structure Analysis of Mechanical Position Limiter for Remote Depth Setting Unit of Torpedo

Aiming at the requirement for mechanical limiting position of remote depth setting unit of a torpedo, this paper analyzes the structure and working principle of the mechanical position limiter of transmission gear in the remote depth setting unit. This structure is designed to use worm gear transmission mode. Based on kinematic analysis and mathematically modelling, the movement attitude and tracks of the diagnostic parts are described quantifieationally, and the important parameters which affect the limiting position of the diagnostic parts are analyzed. The result shows that this structure can meet the requirement for the mechanical limiting position of torpedo setting depth calibration. The research can provide a reference for design and application of similar structures.
