Abstract: A method for identifying installation positions of sensors, which predefines the corresponding relationship between the first sliding member, the second sliding member and the signal features according to the installation directions of the sensors, and then drives the first sliding member and the second sliding member of one of the feed systems to move to obtain and analyze the three-axis signals fed back from the sensors, firstly select responsive three-axis signals, and then determine the axis with the largest response of the three-axis signals so as to identify the sensor installed on the first sliding member. Then, the corresponding relationship between the remaining three-axis signals and the sensors installed on the second sliding members is identified based on the dynamic signal feature and the static signal feature, so as to achieve the purpose of automatically identifying the installation position of the respective sensors.

Abstract: A linear transmission device with capability of real-time monitoring of an amount of a lubricant includes a long shaft, a moving part, a lubricating device and a detecting module. The lubricating device includes a shell and an oil containing unit. The shell is formed with a first accommodating space. The oil containing unit is disposed in the first accommodating space and configured to provide the lubricant to an outer surface of the long shaft. The detecting module includes a temperature sensing unit and a control unit. The temperature sensing unit is configured to detect a current temperature of the oil containing unit. The control unit is connected with the temperature sensing unit and configured to: receive the current temperature; calculate a remaining amount of the lubricant of the oil containing unit based on the current temperature and an oil releasing model; and output the remaining amount.

Abstract: A method for assessing preload degradation of a ball screw is to be implemented by a computer device. The method includes: obtaining an entry of time-domain vibration data based on a vibration signal which is related to vibrations of balls of the ball screw; obtaining an entry of frequency-domain vibration derived data based on the time-domain vibration data; obtaining a vibration eigenvector based on the entry of frequency-domain vibration derived data; performing preload assessment based on the vibration eigenvector, reference vibration vectors and a preload assessment range to obtain a result of the preload assessment; and determining whether preload degradation has occurred on the ball screw based on the result of the preload assessment.
