摘　　要：针对目前传统舵机占据舱室空间大、隐蔽性差等问题,探讨了一种将驱动机构置于舵柄内的高功率密度舰船舵机.在对其结构分析的基础上,探讨了高功率密度舵机的工作原理、在舰船上的安装布置、主作用力的传递路线;从理论上分析了各设计参数对舵机转舵性能的影响;应用Hertz理论,建立了多参数对舵机滚珠传动副性能的影响模型,为高功率密度舵机的结构优化设计、性能改进提供了理论基础.通过和现有其他力矩放大传动装置传递功率能力比较,以及样机试验结果表明,驱动机构位于舵柄内的高功率密度舰船舵机满足现代船舶操纵系统对高性能舵机的要求,具有结构紧凑、功率密度大、材料利用率高、响应快、动态性能好等优点.To overcome problems with traditional ship＇s steering gears which occupy excessive space and have weak concealment,a high-power-density ship＇s steering gear with a driving mechanism that includes a built-in rudder tiller was proposed.Principal forces acting on the steering gear were analyzed,based on structural analysis,working principles,assembly requirements,and restrictions on layout caused by ship design.The influence of design parameters on the performance of the steering gear was then theoretically studied.By using Hertz theory,a model describing the influence of multiple parameters on the steering gear＇s rolling ball transmission performance was established.This provided a theoretical foundation for optimizing its structural design,resulting in significant performance improvements for the steering gear.After comparing this design with other torque amplifying transmission devices as well as prototypes that have been tested,the authors generalized that the high-power-density ship steering gear meets the high performance requirements of modern ship steering control systems with the following advantages： more compact structure,higher power density,more effective material utilization,faster response,and better dynamic performance.
