Title:
METHOD FOR DETECTING MINUTE FLAW IN BEARING FOR COATING MACHINE ROTATING AT LOW SPEED, AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP2007178347
Kind Code:
A
Abstract:
To provide a method for accurately detecting minute flaws in a bearing of a coating controller and quickly replace a flawed bearing, and to obtain a coating sheet with a uniform thickness, without nonuniform thickness (step unevenness) on a coated surface.
An acceleration pick-up 11 is mounted on the bearing 26 or 28 of an object, of which the flaws are detected in a roller-type coating machine 20, and the output detected by the pick-up 11 is amplified in an amplifier 12 and is then passed through a low-pass filter 13 for making frequencies of 500 Hz or lower pass through.
