Abstract
The invention provides a thin-wall gear ring self-centering tensioning installation fixture. The thin-wall gear ring self-centering tensioning installation fixture comprises a spindle basic disc, a compression disc, a compression nut, a spring and a plurality of tensioning steel balls. The compression nut compresses the compression disc, the compression disc compresses the tensioning steel balls arranged in radial through holes in an annular wall, therefore, the purpose of tightening a thin-wall gear ring from inside to outside is achieved, and radial location of the gear ring is completed. In the process of clamping, the tensioning steel balls evenly distributed on the spindle basic disc are simultaneously stressed, the thin-wall gear ring can receive outward tensioning force evenly, and therefore deformation of the thin-wall gear ring is effectively restrained; meanwhile, the centering performance of the thin-wall gear ring on measurement equipment is guaranteed. The thin-wall gear ring self-centering tensioning installation fixture effectively reduces deformation of the thin-wall gear ring in the process of clamping, eliminates the steps of concentric centering on the measurement equipment after clamping is completed, and improves clamping efficiency and detection accuracy.
