Abstract

The invention discloses a gear box fault prediction, monitoring and diagnosis method and a corresponding device. The method comprises the steps: collecting working data of a gear box and train operation data; and carrying out intelligent analysis processing on the working data of the gear box and the train operation data, and predicting and obtaining fault data of the gear box. According to the invention, the technical problem that the fault of the train gearbox cannot be accurately predicted in time is solved.

Description

technical field [0001] The invention relates to the field of gearboxes, in particular to a method for fault prediction, monitoring and diagnosis of a gearbox and a corresponding device. Background technique [0002] Gearbox is a key component of rail transit train transmission system. The small gear of the gearbox is flexibly connected to the traction motor through a coupling; the large gear of the gearbox is pressed on the axle, and the gearbox transmits power through the meshing of the gears, and transmits the power of the traction motor to the axle to drive the vehicle to run. [0003] The fault diagnosis system of the traditional gearbox collects a single data of the gearbox, and then judges whether the measured data of the gearbox exceeds the threshold, and confirms the operating status of the gearbox according to the judgment result. However, due to the different operating conditions of each vehicle and different seasonal environmental factors, it is difficult for the...
