| Abstract: | The shaft axial run out must be got exactly by the precise detecting system. In this paper, some factors, such as the transducer performance, the circuit non linearity, the displacement direction decision and zero point remainder voltage, which affect the detecting precision of the shaft axial run out, have been studied. The optimization of oscillatory frequency and the design of the circuit of ideal diode have been discussed, and a utility circuit has been designed to meet the requirement of detection of the precise straightening press. Some experiments have been performed and the detecting absolute errors were below 0.01mm. The system can be applied to the precise straightening press detecting system. |
