Design and application of elastic diaphragm type group chuck
When grinding the inner bore of the gear after quenching, our factory used the elastic taper sleeve which is positioned by the pitch point and the clamp which is axially moved and clamped. The centering accuracy is low, and the operation requirements for the workers are high. The surface of the new tooth has increased the requirement for the radial runout of the ring gear. The original structural clamp cannot be adapted, so we designed the elastic diaphragm type group chuck.
