摘　　要：研究表明,当船舶在波浪中航行时,由于受到水浮力、水阻力、船舶重力及惯性力等作用,船体会产生弯曲变形,该变形在一定程度上影响到沿船体纵向布置的齿轮机构轮齿的啮合性能。本文针对传统的船用齿轮在强度计算中不计船体变形及齿间摩擦力的问题,以沿船体纵向布置的渐开线斜齿减速齿轮机构为研究对象,通过系统地分析、研究,推导出综合考虑船体变形及齿间摩擦的船用斜齿轮齿面接触疲劳强度计算公式,以进一步完善船用齿轮的强度计算。算例表明,船体变形及齿间摩擦对齿轮强度的影响的确不可忽视。It has been testified that the bending deformation of ship hull will take place while sailing in the waves, because of the function of the buoyancy, resistance, gravity and inertia force etc, and deformation will affect the mesh performance of the helical gearing arranged along the ship longitudinal direction. In addition, the effect of sliding fric- tion between gear teeth can not be neglected. However, the influence both ship hull defurmation and friction between gear teeth are omitted in strength calculation of gear driving fixed in boat in traditional design. As for these two points, the author deduces the equation which perfects the helical gear strength calculation, under the joint action of the shipbody deformation and the sliding friction between gear teeth. The conclusion indicated that it is right.
