Title:
MEASURING METHOD FOR MINUTE ANGULAR VELOCITY AND MINUTE ANGLE AND DEVICE FOR GENERATING THESE QUANTITIES
Document Type and Number:
Japanese Patent JPH0465623
Kind Code:
A
Abstract:
PURPOSE:To measure the minute angular speed and minute angle by mounting a body to be measured on a rotary table, rotating the table and causing the displacement of an abutting rod, and calculating a necessary number. CONSTITUTION:Such an abutting member that the rotation of a variable speed motor 6 is changed by a speed change means and converted by a converting means 8 into linear motion is formed abutting on the flank of the tip part of the rigid rod 9 of specific length, having its end part formed integrally sideward from the center of the rotary table 3 capable of rotating in a horizontal plane, in the horizontal plane. Then the body 16 to be measured is mounted on the table 3 and the motor 6 is rotated for a specific time to displace the tip part of the rigid rod 9 abutting by the horizontal movement of the abutting member, and the fine angular speed and fine angle are calculated from the specific length of the rigid rod, the displacement of the tip part, the rotating speed of the variable speed motor, the speed change ratio of the speed changing means, and the specific rotation time of the variable speed motor.
