It is lower that serious abrasion can occur, the index severe overweight such as out-of-roundness, surface flatness, roughness of wheel is caused, influences vehicle
Safe operation, therefore inspection and repair system provides, vehicle runs and wheel is carried out into turning after certain mileage, recovers the precision of wheel
Index, to ensure the safe operation of vehicle.
Axle box bearing is a critical component of vehicle safety operation, by can only lean on temperature index in vehicle operation
Judge the state of bearing, and judgement of the temperature index to the initial failure of bearing is helpless, temperature is once exceeded, then marks
Will that bearing fault is very serious, may threaten the safe operation of vehicle at any time.If the turning cycle of wheel can be coordinated,
Judge can be monitored to the state of axle box bearing, then can greatly improve the safety of vehicle operation while turning wheel
Property.
Utility model content
The utility model provides a kind of bearing testers for handing over car wheel-set non-pulling wheel Xuan to repair for rail, to in-orbit friendship
The problem of detecting during car wheel-set non-pulling wheel Xuan is repaiied while to wheel set bearing state, to improve the safety of vehicle operation
Property.
A kind of bearing testers for handing over car wheel-set non-pulling wheel Xuan to repair for rail, the detector include data acquisition unit, work
All-in-one, and first, second, third and fourth vibrating sensor are controlled,
First, second, third and fourth vibrating sensor accesses data acquisition unit, and data acquisition unit is connected by communication serial port
To industrial computer, by the data transfer collected to industrial computer,
The display of industrial control all-in-one machine, for the figure shows of testing result,
First, second vibrating sensor access rail hands over the first round pair of the bogie of car,
Third and fourth vibrating sensor access rail hands over the second wheel pair of the bogie of car.
The first, second, third and fourth vibrating sensor is separately mounted to Xuan and repaiies biography in the middle part of the upper paw of lathe
In sensor mounting groove, and fixed with M6 bolts, the cable of vibrating sensor, which is arranged in the wire casing of sensor, to be fixed.

Use situation.Communicated between Acquisition Circuit and industrial computer using RS232.Industrial control all-in-one machine with touch-screen, is installed on operator side
The position of convenient to operate.
In Xuan repaiies work, paw is compressed axle box by operator, without additionally being adjusted to vibrating sensor, bearing
Vibration signal is delivered to vibrating sensor by axle box, paw.Detector detects the vibration data of bearing, self-excited oscillation in future sensing
The vibration signal of collection is demodulated and wrapped with FFT processing into data signal, data acquisition unit by the analog-signal transitions of device
Network total value and envelope frequency spectrum, the alarm limits according to setting judge the degree of injury of bearing, and according to the bearing designation monitored
It is corresponding to arrive component feature value, provide the damage report of specific part.
What deserves to be explained is created although foregoing teachings describe the utility model by reference to some embodiments
Spirit and principle, it should be appreciated that, the utility model is not limited to disclosed embodiment, and each side is drawn
Divide and also do not mean that the feature in these aspects can not combine, this division is merely to the convenience of statement.The utility model purport
