METHOD AND DEVICE FOR DETECTING UNBALANCE IN STATIC BALANCE OF ROTARY BODY

摘要

PURPOSE:To quickly detect the unbalance in the static balance of a rotary body by measuring the weight distribution of the trisected point of on a circumference centering around the center of the rotation of a rotary body and executing the vector operation of the value thereof by using a microcomputor. CONSTITUTION:A weight detecting sensor 2 is arranged on the supporting point forming the apex of the equilateral triangle located on a horizontal plane at the position of the rotary body placing part formed on the upper face of a machine body, making the center of the equilateral triangle and that of a rotary body 1 coincident with on the same vertical line and the body 1 is placed on three rotary body supporters 3. The weight information at the supporting point of the body 1 detected by the sensor 2 is converted into a numerical value by a quantity/numerical value convertor 6 and fed to a microcomputor 7. A vector operation is performed in the computor 7 by the command from a controller 8, the weight and position of the unbalance are calculated and recorded by a recorder 10 as well as displayed on a display device 9. The unbalance in the static balance of the rotary body can quickly be detected.
