Document Type and Number:
WIPO Patent Application WO/2019/058965
Kind Code:
A1
Abstract:
Provided is a diagnostic method for appropriately recognizing the state of a rolling face (11) of a raceway member (1) in a rolling guide device and the lubrication state of a rolling body (6), wherein: a vibration sensor (35) is used to detect the relative vibration displacement between the raceway member (1) and a moving member (2), and a detection signal of the vibration sensor (35) and a predetermined threshold are compared; when the detection signal is greater than the threshold, it is determined that the traveling state of the moving member (2) with respect to the raceway member (1) is abnormal, a lubricant is supplied to the rolling guide device, and the detection signal of the vibration sensor (35) is re-read after the supply of the lubricant is completed; and when said detection signal exceeds the threshold again, it is determined that the supply of the lubricant is defective or the rolling face (11) of the raceway member (1) is defective.
