The invention relates to a slewing bearing and a manufacturing method and application thereof. The slewing bearing comprises an inner gear ring, an outer gear ring and a rolling body, first meshing teeth are arranged on the inner side of the inner gear ring, second meshing teeth are arranged on the outer side of the outer gear ring, and the outer gear ring comprises a first outer gear ring body and a second outer gear ring body which are fixedly connected. The manufacturing method of the slewing bearing comprises the following steps: processing one metal circular ring into the inner gear ring, and fastening the two metal circular rings together to be processed into the first outer gear ring and the second outer gear ring. The slewing bearing is applied to motion control of a workpiece clamping assembly in the polishing machine. According to the slewing bearing, the inner gear ring and the outer gear ring are directly connected through the rolling bodies, the size miniaturization of the slewing bearing with the inner teeth and the outer teeth is achieved, the strength of the slewing bearing is improved, and due to the design that the outer gear ring is divided into two parts, the slewing bearing is easier and more convenient to install.

    本发明涉及一种回转支承及其制作方法和应用。所述回转支承包括内齿圈、外齿圈和滚动体,所述内齿圈内侧设置有第一啮合齿,所述外齿圈外侧设置有第二啮合齿,外齿圈包括固定连接的第一外齿圈和第二外齿圈。该回转支承的制作方法是将一个金属圆环加工成内齿圈,将两个金属圆环紧固在一起加工成第一外齿圈和第二外齿圈。所述回转支承在抛光机中应用于工件夹持组件的运动控制。本发明的回转支承由内齿圈与外齿圈通过滚动体直接接合,不但实现了具有内外齿的回转支承的体积小型化,而且提升了回转支承的强度,外齿圈一分为二的设计,使回转支承的安装更加简单、便捷。
