Abstract

PURPOSE: To obtain a chuck for tachometers free of slip during the measurement by means of a cone having a fixed slope which is fitted into the shaft and the shaft tip centered in the magnetic chuck.
CONSTITUTION: A chuck body 10 is pressed against the end of a rotating shaft 5 of a rotary body in such a manner that the tip of a cone 13 projected from the tip of the chuck body 10 almost aligns with the center of a tail hole 6 of the rotary body for an object to be measured. Said mechanism causes the body to adhere to the shaft 5 by the magnetic force of a permanent magnet 11. When an attachment 14 is rapped lightly under the condition where the faces of the cone 13 and the hole 6 are deviated, a strong force is generated toward the right angle against the axial direction due to the wedging effect and causes the body 10 to move to the position at which the top of the cone 13 aligns with the center line of the shaft 5 and fastened at that place, allowing the shaft 5 and the body 10 to turn maintaining the position free of eccentricity. Thereby, a chuck for tachometers can be obtained free from slip developing during the measurement.
