Problems solved by technology

As a key link in the conversion of torque and speed, once the planetary gearbox fails, it will cause the entire power transmission chain to fail and stop, and it will lead to the death of the machine
[0003] Traditional online detection and analysis devices suitable for wind power gearboxes and industrial planetary gearboxes cannot perform comprehensive inspections on gearboxes

Abstract

The invention relates to an analysis system for online detection of performance and fault of a gearbox, comprising: a sound intensity probe sensor for collecting noise data during operation of the gearbox, an accelerometer for collecting vibration data during operation of the gearbox, a temperature sensor for collecting temperature data during operation of the gearbox, a pressure sensor, a torqueand speed sensor, a data acquisition system and a B&K system software analysis workstation; the data acquisition system forms a communication connection with the sound intensity probe sensor, the accelerometer, the temperature sensor, the pressure sensor, and the torque and speed sensor; the data acquisition system is in a communication connection with the B&K system software analysis workstation.The analysis system for online detection of performance and fault of the gearbox has the advantages that the data of each sensor can be centralized, and the operation performance of the gearbox undera specific working condition can be detected online for comprehensive analysis and diagnosis of the fault of the gearbox.

Description

technical field [0001] The invention relates to an on-line detection and analysis system, in particular to an on-line detection and failure analysis system of a gearbox. Background technique [0002] Wind power transmission gearboxes and industrial planetary gearboxes are compact in structure, small in size, light in weight, large in transmission ratio, strong in carrying capacity, stable in transmission, and high in transmission efficiency. They are suitable for high-speed high-power and low-speed high-torque mechanical transmissions. In the actual operation process, the gearbox has complex dynamic heavy load forces and is prone to mechanical failure. In each product development and manufacturing process, conceptual design, preliminary design, detailed design, design verification, small batch trial production, and mass production are required. Among them, design verification is the most important stage of new product development reliability, including DFMEA confirmation, e...
