Abstract
The utility model relates to a trouble diagnose experimental stage for rotary machinery, which is composed of an electrical machine, a fault gear wheel, a driving gear, a coupler, a balance disc, a generator, a pillow block, a loader, a fault bearing and an a plane and two pits. The utility model has the advantages of easy operation and simple and rapid replacement of the fault elements when different fault experiments are carried out. The utility model can meet the teaching requirement. A sensor has the advantages of easy installation, obvious fault information output and high signal-to-noise ration. The sensor also has unicity. Students can obtain the spectrogram corresponded with the fault phase easily, and enhance the perceptual knowledge.
Description
The utility model is a kind of rotary machinery fault diagnosis experiment table about universities and colleges' teaching usefulness.
It is investigated newly as can be known: the domestic universities and colleges similar experiment table in laboratory can only be to " die misalignment " of shaft coupling, and " imbalance " of tumbler reaches " sliding bearing " fault diagnosis and experimentize.And to " gear distress ", the diagnostic function of " rolling bearing " lacks.
The purpose of this utility model: for provide a kind of easy and simple to handle, directly perceived, export tangible rotary machinery fault diagnosis experiment table with, failure message more than one and satisfy requirement in universities and colleges' teaching.
Principle of the present utility model: fault gear or fault bearing that integral body is supporting are placed in the system on request, then sensor is installed near the place, plane the specified fault element, enter computing machine and handle by amplifier, interface box with special software, can pass through screen display, or print figure and related parameter is respectively arranged.And crossing deposit record time domain, amplitude domain, frequency field figure and parameter, the learner just obtains the corresponding relation of this fault and above-mentioned figure and parameter.
Advantage of the present utility model: easy to operate, when doing the different faults experiment, it is simply rapid to change fault element, satisfies the teaching requirement.Sensor is easy for installation, and failure message output is obvious, and has unicity, the signal to noise ratio (S/N ratio) height, and the student can obtain and the corresponding spectrogram of fault easily, strengthens perceptual knowledge.The collection of fault information data is handled and displayed record promptly can realize supporting, analysis, demonstration and record with the existing vibration analysis instrument of user.The experiment table volume is little, can be placed directly on the table, and good looking appearance, color is soft, and relative low price can well be the teaching service.
Accompanying drawing 1 is a synoptic diagram of the present utility model.It is by motor (1), whole interchangeable fault gear simulation structural unit (2), three same model shaft couplings (3), balancing frame (4), generator (5), whole interchangeable fault bearing test head (6), transmission gear (7), bearing base (8), spiral loader (9), fixed gear (10) and plane and two pits (11) are formed.Wherein, after fault gear simulation structural unit (2) and transmission gear (7) are located with plane and two pits with support, fastening with screw.Gear (7) with gear (10) ratio of gear is: 1:2, gear (10) is 0.5～2 with gear (2) ratio of gear.
Accompanying drawing 2 is synoptic diagram of whole interchangeable fault bearing test head (6).It is by half a coupler (12), end cap (13), and flexible shaft bearing sleeve (14), (16), and load bearings seat (15), axle (17), fault bearing (18), (21), load bearings (19), (20), and sleeve (22), garden nut (23) is formed.It can wholely from support (8) take out or put into.Wherein, bearing (18), (19), (20), (21), with axle (17), with interchangeable bearing holder (housing, cover) (14), (16), all adopt tighter excessive the cooperation with load bearings seat (15), its axial location is by the shaft shoulder, and sleeve (22) and garden nut (23) are fixing.Interchangeable rolling bearing experiment head (6) is by flexible shaft bearing sleeve (14), and the interior external diameter of (16) changes to satisfy with guaranteeing measures different fault bearings (18), when (21) and the concentricity of system.Interchangeable rolling bearing experiment head (6) position in support is by flexible shaft bearing sleeve (14), the convex shoulder of (16) card position.
The synoptic diagram of accompanying drawing 3 whole interchangeable fault gear simulation structural units (2), it is by bearing seat (24), socket head cap screw (25), fault gear (26), bearing (27), axle (28), half a coupler (29), bearing cap (30), pressure ring (31) is formed.It can integral body be taken out or put into from system.Behind plane and two pits (11) location, fastening with screw, wherein, bearing (27) all adopts with axle (28) and bearing seat (24) and excessively cooperates.Its axial location is by the shaft shoulder, and bearing seat (24) bearing cap (30) is fixing.Gear (26) and axle (28) are by flat key and excessively cooperates connection, the usefulness shaft shoulder and pressure ring (31) axial location.
The centre distance of it and system matches is, the ratio of gear by gear (10) and gear (7) changes (being that the number of teeth changes) and guarantees.
Embodiment of the present utility model: 1. Gear Fault Diagnosis experiment.Transmission gear (7) is taken away, putting whole interchangeable fault gear simulation structural unit (2) locatees by plane and two pits, screw is fastening, adjust shaft coupling (3) and balancing frame (4), make its axis centering, at the place, plane, bearing seat top of gear simulation structural unit (2) sensor installation, connect charge amplifier, interface box loads running then, observe the time domain corresponding, frequency domain figures by on screen, can directly showing after the supporting Computer Processing that dedicated analysis software arranged with gear distress.2. bearing failure diagnosis experiment.Fault gear simulation structural unit (2) is taken away, put into transmission gear (7) and whole interchangeable fault rolling bearing experiment head (6).After running well, test by spiral loader (9) loading, by on screen, showing relevant figure after the Computer Processing.
