Bearing vibration monitoring system

Abstract

The invention discloses a bearing vibration monitoring system. The system comprises a bearing, a supporting sleeve, vibration sensors, an electronic diagnosis module, an industrial personal computer,a PLC, a display terminal, an alarm device and a storage device, the bearing is installed on a gear shaft, the gear shaft is installed in an inner hole of the supporting sleeve, and the vibration sensors are connected to the horizontal direction and the vertical direction of the supporting sleeve respectively to collect vibration data of the bearing; the vibration sensors transmit signals to the electronic diagnosis module, and the electronic diagnosis module outputs a real-time vibration spectrogram by processing the signals or outputs the signal to the PLC by signal processing; the PLC can display real-time data of bearing vibration on the display terminal through signal processing and trigger the alarm device to respond when a monitoring value exceeds a set value. The storage device cancall operation data for comparative analysis. Damage of parts can be avoided, accidental shutdown is prevented, the service life of equipment is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a bearing vibration monitoring system, which belongs to the technical field of state monitoring of main transmission bearings of press machines. Background technique [0002] Bearings are an important part of the main transmission parts of presses. Whether the bearings are installed or not and whether they are in good condition will directly affect the accuracy, life and performance of the bearings. The main transmission part is a crucial driving part in the press, and its operation reliability is particularly important for the accuracy and life of the whole machine. At present, the state monitoring of bearings is generally realized by measuring the bearing temperature, which can characterize the deterioration factors of the mechanical structure. However, when the bearing temperature rises significantly, the operating conditions of the bearings are already very bad, and the bearings are basically damaged. Contents of the inve...

At present, the state monitoring of bearings is generally realized by measuring the bearing temperature, which can characterize the deterioration factors of the mechanical structure. However, when the bearing temperature rises significantly, the operating conditions of the bearings are already very bad, and the bearings are basically damaged.
