驱动小齿轮

驱动小齿轮是回转支承和驱动系统中的关键机械部件，通常具有斜齿或直齿，与回转支承的内齿圈或外齿圈啮合。它将电机或液压系统的输入扭矩转换为大型结构的受控旋转运动，精确的齿形确保高效的动力传递和最小的齿侧间隙。

驱动小齿轮基于齿轮啮合的基本原理工作，其齿与回转支承齿圈的齿啮合。当小齿轮在输入扭矩作用下旋转时，产生滚动作用，驱动回转支承旋转，从而实现重载的受控运动，其机械优势由齿轮比和齿形决定。

The drive pinion operates on the fundamental principle of gear meshing, where its teeth engage with the gear teeth of the slewing bearing ring. As the pinion rotates under input torque, it creates a rolling action that drives the slewing bearing's rotation, enabling controlled movement of heavy loads with mechanical advantage determined by gear ratio and tooth geometry.
