There is a problem that "the measured rotor rotates on the roller for a long time, the bearing portion of the measured rotor is damaged." As a solution to this problem, Japanese Patent Publication No. 50-16956.
There is a gazette. In addition to the roller drive mechanism for measurement, a drive mechanism for directly driving the rotor to be measured was provided to shorten the rotation time on the roller during measurement. However, in this method, the roller is driven at the time of measurement, and the vibration of the roller drive mechanism (additional vibration of the belt that drives the roller)
Is added to the measured rotor, resulting in a measurement error.
