Abstract
A novel high-precision rigid-flexible coupling rotating platform includes a foundation, a rigid bearing, a bearing sleeve, a core rotating platform, a rotating driver and a coder; the bearing sleeve is fixed on the foundation; the rigid bearing is in rotatable drive connection with the core rotating platform, and connected with the foundation through the bearing sleeve; an upper surface of the core rotating platform is provided with a plurality of groups of flexible hinges; when the rotating driver applies a driving force to rotate the core rotating platform, the driving force elastically deforms the flexible hinge rings. The flexible hinges are used and disposed on the upper surface of the core rotating platform; without disassembling the whole rotating platform, a corresponding group of flexible hinges can be changed but an assembling relationship between other groups of flexible hinges cannot be broken.
