DEVICE FOR MEASURING THE INTERNAL PROFILE OF A HOLLOW SHAFT |
| 摘要 |
A sensor is placed on a plate lowered into the hollow of the shaft and guided by taut wires between a lower attachment device and an upper motorised winder. The deformations, responsible for measurement errors and caused either by static deformations, produced by the weight or poor construction of the apparatus, or by vibrations, are to a large extent eliminated. |
