The application discloses a speed reducer capable of automatically judging faults. The speed reducer comprises a speed reduction transmission mechanism, a transmission shaft, a transmission bearing, abox body, an automatic fault judging device and a plurality of first sensors, wherein the first sensors are installed on at least one part of the speed reduction transmission mechanism, the transmission shaft, the transmission bearing and the box body, and are used for detecting and uploading sensing signals of corresponding parts of the speed reducer; the automatic fault judging device is use for decomposing, reconstructing and energy calculation on the sensing signals of training samples respectively, energy vectors formed by the calculated signal energy are taken as the training samples tobe input into neural networks of the corresponding signal types for training respectively, and the sensing signals uploaded by the plurality of first sensors, of different speed reducer parts are input into the trained neural networks of the corresponding signal types, and speed reducer components of the faults output by the neural networks and fault type information are obtained. The speed reducer improves the automation and intelligence degree of fault judgment, and optimizes weights and thresholds of the neural networks.

    本申请公开了一种故障自动判别的减速机,包括减速传动机构、传动轴、传动轴承、箱体、故障自动判别装置以及多个第一传感器,第一传感器安装于其中至少一个部分上,用于检测并上传减速机相应部分的传感信号;故障自动判别装置用于对训练样本传感信号分别进行分解、重构和能量计算,并将由算出的信号能量所形成的能量向量作为训练样本分别输入对应信号类型的神经网络进行训练,并将多个第一传感器上传的不同减速机部分的传感信号输入训练完成的对应信号类型的神经网络,得到神经网络输出的故障发生的减速机组成部分及其故障类型信息。该减速机提升了故障判别的自动化和智能化程度,并且对神经网络权值和阈值进行了优化。
