齿轮齿（如适用）

回转支承（也称转盘轴承）外圈或内圈上集成的齿轮齿，提供动力传递的机械接口。这些齿与小齿轮啮合，将旋转运动转化为受控扭矩，使大型结构在重载下平稳旋转并保持精确定位。齿轮齿通常直接切割在轴承的淬硬钢圈上，形成一个集承载能力和动力传递功能于一体的整体部件。

回转支承上的齿轮齿基于齿轮啮合的基本原理工作。当小齿轮与轴承圈上的齿啮合时，旋转力通过接触表面传递。渐开线齿廓确保平稳啮合和脱开，且侧隙最小，同时轴承滚道同时承受轴向、径向和倾覆力矩载荷。这种集成设计无需单独的齿轮组件，降低了复杂性，并在需要旋转和承载的应用中提高了机械效率。

Gear teeth on slewing bearings operate on the fundamental principle of gear meshing. When a pinion gear engages with the teeth on the bearing ring, rotational force is transferred through the contact surfaces. The involute tooth profile ensures smooth engagement and disengagement with minimal backlash, while the bearing's raceways support axial, radial, and moment loads simultaneously. This integrated design eliminates the need for separate gear assemblies, reducing complexity and improving mechanical efficiency in applications requiring both rotation and load support.
