Abstract
The utility model discloses a steel rolling antifriction bearing fault monitoring device. The device comprises a first vibration sensor and a second vibration sensor. The first vibration sensor is disposed on a rack. The second vibration sensor is disposed on a bearing base. The first and the second vibration sensors are connected to a controller. The controller is further connected to an alarm unit. The device effectively eliminates noise interference and monitors the operation conditions of the antifriction bearing in a real-time manner.
Description
Technical field
The utility model belongs to technical field of steel rolling, is specifically related to a kind of steel rolling rolling bearing fault monitoring device.
Background technology
Bearing be the most key in rolling mill be also one of the most flimsy mechanical component.If when bearing damage can not be found timely, can not produce qualified product, and can cause the damage of other parts.Rolling mill is in the time of work, and near temperature rolling bearing arrives hundreds of degree; The noise that near various plant equipment are sent is huge.So in the time that the rolling bearing of rolling mill is carried out to status monitoring, need to get rid of the interference of various noises, improve the signal to noise ratio (S/N ratio) of signal of rolling bearing.Existing monitoring device can not solve the interference that noise exists well.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of steel rolling rolling bearing fault monitoring device is provided, and adopts this device effectively to remove the interference of noise, the operating mode of Real-Time Monitoring rolling bearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of steel rolling rolling bearing fault monitoring device, comprise the first vibration transducer and the second vibration transducer, this first vibration transducer is placed in frame, the second vibration transducer is placed on bearing seat, and the first vibration transducer is connected with controller respectively with the second vibration transducer, and this controller is also connected with warning device.
Further, this first vibration transducer and the second vibration transducer are acceleration transducer.
Further, it is coated that the outside of this first vibration transducer and the second vibration transducer adopts the material of resistance to wearing.
A kind of steel rolling rolling bearing fault of the utility model monitoring device, vibration transducer is positioned in frame as reference point, and numerical value is reliable, the signal value of default dependent failure in controller, realize the fault that Real Time Monitoring exists, for safety in production provides guarantee.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of steel rolling rolling bearing fault of the utility model monitoring device.
Embodiment
As shown in Figure 1, a kind of steel rolling rolling bearing fault monitoring device, comprise the first vibration transducer 2 and the second vibration transducer 5, the first vibration transducer 2 is placed in frame 1, the second vibration transducer 5 is placed on bearing seat 6, and the first vibration transducer 2 is connected with controller 3 respectively with the second vibration transducer 5.This controller 3 is also connected with warning device 4.The first vibration transducer 2 and the second vibration transducer 5 are acceleration transducer, and the first vibration transducer 2 and the second vibration transducer 5 adopt the material of resistance to wearing coated.
Principle of work of the present utility model is: the vibration signal value by rolling bearing under no-load condition and occur that the signal value of different faults is input to controller 3, the first vibration transducer 2 and the second vibration transducer 5 are input to controller 3 at the signal value detecting, signal is processed processing by controller 3, draw except the signal value after making an uproar, the signal value calculating is compared with the signal value of pre-input, can judge the failure problems of steel rolling rolling bearing, and send signal to alarm device 4.
