Title:
張力測定システム
Document Type and Number:
Japanese Patent JP7034851
Kind Code:
B2
Abstract:
To correctly measure tension of an endless roll suspension transmission member by correctly distinguishing the characteristic frequency of the endless roll suspension transmission member from vibration of a plurality of frequencies generated in the endless roll suspension transmission member of a roll suspension transmission device.SOLUTION: In a characteristic frequency calculation part 133, as a characteristic frequency f0 of a belt 24, the frequency is calculated, whose peak appears commonly in three frequency spectra acquired in each of a measurement period P1 during a period when a rotation speed ω of a motor 21 is a constant speed ω1, a measurement period P2 during the period when the rotation speed ω is a constant speed ω2, and a measurement period P3 during the period when the rotation speed ω is a constant speed ω3 and which is not a multiple of the rotation frequency of the motor 21.SELECTED DRAWING: Figure 2
