Abstract
The utility model discloses a low -speed overload bearing test platform. The technical scheme who adopts includes the bottom plate to and set up the bed hedgehopping piece at the bottom plate both ends, wherein bed hedgehopping piece sets up the motor, another bed hedgehopping piece sets up bearing frame, its characterized in that: the output shaft of motor passes through the coupling joint speed regulator, the coupling joint axle is passed through to the other one end of speed regulator, the other end of axle is connected with the bearing frame, at the epaxial bearing that sets up, corresponds the bearing below and sets up the jack. The utility model discloses a low -speed overload bearing test platform, the motor through adjusting bearing rotating speed, adds screw jack through being connected with the speed regulator bottom the bearing, simulate the effect of exerting pressure for the bearing. Acoustic emission sensor is installed additional in the outer lane for gather the acoustic emission signal of bearing operation, and upload to upper machine in measuring and assay.
Description
Technical field
The utility model relates to bearing technical field of measurement and test, and concrete is a kind of bearing test platform.
Background technology
Rotating machinery is the emphasis of equipment condition monitoring and fault diagnosis work always, and bearing because of start sensitive, operate steadily, be easy to exchange and the advantage such as operation and maintenance expense is low, obtain in rotating machinery and apply very widely.Because bearing is usually used to the key position of high rotating speed, top load, high precision apparatus, so are directly connected to performance and the life-span of entire machine in its running quality and serviceable life.So bearing working status monitoring and diagnosis tool are of great significance, and be also one of the developing emphasis technology in mechanical fault diagnosis field always.
In order to overcome the deficiency (can not pinpoint the problems early) that above-mentioned technology exists, the early-stage weak fault of bearing will cause catastrophic consequence, but the vibration signal of initial failure is very faint, again easily flood by the larger low frequency environments noise of relative amplitude around, thus cannot effectively detect out of order existence.Because acoustic emission is the high frequency stress wave signal that damaged structure itself sends, be not subject to the interference of ambient noise, therefore acoustic emission detection method adopt by this programme.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of super slow-revving rotary machinery fault diagnosis platform.
For solving the problem, the technical solution adopted in the utility model comprises base plate, and be arranged on the keel at base plate two ends, wherein one piece of keel arranges motor, another block keel arranges bearing seat, it is characterized in that: the output shaft of described motor connects speed regulator by shaft coupling, the other one end of described speed regulator is by shaft coupling coupling shaft, and the other end of described axle is connected with bearing seat, axle arranges bearing, below corresponding bearing, lifting jack is set.
Described low speed heavy-duty bearing test platform, is characterized in that: described keel is wooden unit.
Described low speed heavy-duty bearing test platform, is characterized in that: described lifting jack is screw jack.
Low speed heavy-duty bearing test platform of the present utility model, motor, by being connected with speed regulator, by regulating bearing rotational speed, adds screw jack bottom bearing, simulates and executes stressed effect to bearing.Installing calibrate AE sensor additional in outer ring, for gathering the acoustic emission signal that bearing runs, and being uploaded to host computer for examination and analysb.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 to 3 is structural representations of different angles of the present utility model.
Embodiment
As shown in Figures 1 to 3, low speed heavy-duty bearing test platform of the present utility model, comprise base plate 1, and be arranged on the keel 2 at base plate 1 two ends, wherein one piece of keel arranges motor 3, another block keel arranges bearing seat 4, the output shaft of described motor 3 connects speed regulator 5 by shaft coupling 4, and described speed regulator 5 in addition one end, by shaft coupling 4 coupling shaft 6, reduces the rotating speed of motor by speed regulator.Described axle 6 other end is connected with bearing seat 4, and axle 6 arranges bearing 7, arranges lifting jack 8 below corresponding bearing 7.
In further optimization such scheme, described keel 2 is wooden unit.Adopt wooden unit as keel, there is the effect of buffering, to alleviate vibration during electric machine rotation, reduce fault erroneous judgement.Described lifting jack 8 is screw jack.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
