Gear driving fault diagnosis system

Abstract

The invention discloses a gear driving fault diagnosis system. The gear driving fault diagnosis system comprises a foundation, a driving motor, a dynamic torque sensor, an encoder, a two-stage planetary gear case, a parallel planetary gear case, a magnetic powder brake, a driving wheel, a parallel gear, a vibration sensor assembly and a control system, wherein the gear cases are designed into special structures so as to rapidly replace gear parts, multiple identical shafts are parallelly mounted, single fault signals and an integrated signal including different faults can be acquired, adjustment on the quantity of external parallel gears is carried out, vibration signals of gears having different faults and same faults under loaded and zero load states can be acquired, automatic program control and manual control on start, stop and an operation speed of the motor can be carried out, and closed loop feedback control can be carried out. The system is advantaged in that requirements of gear driving fault diagnosis research analysis works for hardware equipment can be satisfied through integrated design.

Description

technical field [0001] The invention relates to a fault diagnosis system, in particular to a gear transmission fault diagnosis system. Background technique [0002] Gear transmission is the most widely used form of transmission in mechanical transmission. Due to its long-term exposure to various alternating loads, impacts and frictions in the working process or its own defects left in the manufacturing process, it is prone to Failure or even damage, and for the gear transmission system that has a failure, it will generate noise, accelerate equipment wear and reduce equipment life, and seriously damage the equipment directly, affect production, and bring economic losses, especially for some special important applications. Occasionally, once the equipment fails, the loss is immeasurable. Therefore, in order to minimize the economic loss caused by these uncertain gear mechanical failures, we need to make a diagnosis in the early stage of the failure, so as to provide a scienti...
