Description
The utility model relates to a kind of mechanical engineering equipment fault diagnosis Comprehensive Experiment equipment, in particular for the mechanical fault diagnosis comprehensive experimental device of teaching or development test.
The article of the technology of equipment fault diagnosis and device aspect and monograph, existing more report in some publications and books.For example: " chief editor such as equipment fault diagnosis handbook Xu Min, publishing house of Xi'an Communications University; " mechanical fault diagnosis " curved beam is given birth to, He Zhengjia writes Shanghai science tech publishing house; " vibration, test and diagnostic " periodical.Its content mainly is that equipment occurs from engineering problem is set about various detections and the fault analysis carried out, or does the single failure diagnostic test on certain device, can solve Device Diagnostic problem in the working site.But if in order to cultivate this respect personnel or to carry out development test work, it is perfect inadequately that field experiment environment and condition just seem.In industrial actual environment, can not be timely provide the various faults of equipment to learn and train to the student, do not allow on production equipment, to carry out various development tests yet.
The purpose of this utility model is to cultivating, train mechanical fault diagnosis personnel's unit and development test department that a kind of mechanical fault diagnosis comprehensive experimental device is provided.
The utility model comprises: the power source part, form by alternating current generator and speed regulator, and in the rated speed of alternating current generator, adjust motor speed arbitrarily and change the frequency of operation of experiment table.The fault simulator part is by all kinds of no damages, damage and defective spur gear, helical teeth, herringbone wheel, rolling bearing, sliding bearing, hydrostatic bearing and all kinds of unitor, unbalance dynamic simulator, loading device are formed replaceably.Can simulate spur gear, spiral gear, herringbone wheel broken teeth, spot corrosion fault; Rolling bearing lacks several spot corrosion faults of lubricating oil and ball and inside and outside circle; Sliding bearing lacks the diagnosis of lubricating oil, wearing and tearing, tile kilning; During installation, the fault of decentraction between the input shaft of motor shaft and simulator; The simulation installation shaft with spool between not parallel or centre distance is overproof and cause the abnormal fault of gearing mesh; Faults such as the hydrostatic bearing oil pressure is undesired, oil circuit obstruction, bearing temperature rising; The monitoring of equipment carrying and the simulation of rotating machinery unbalance dynamic.The test section is made up of acceleration, speed, displacement, temperature, power, pressure transducer.Be connected with multifunctional converter and computing machine, constitute monitoring analysis system.Also can join, then the information of record is input in the specialized analyzer, carry out more deep analysis with record storage.Wherein, speed regulator is contained on the motor, motor is connected by the input shaft of shaft coupling with the fault simulation part, loading device connects by the shaft coupling output shaft, the acceleration of test section, speed, displacement, temperature sensor are contained on the gear shaft holder, and power, pressure transducer are contained on the bearing seat of loading device.
Effect of the present utility model is embodied in: diagnostic function is comprehensive, can the real simulated engineering in, more than ten kind of common faults phenomenon of plant equipment.By it being carried out the detection and the analysis of acceleration, speed, displacement, pressure, temperature, power energy parameter etc.Distinguish, verify all kinds of faults more intuitively, make the student in the short time, can grasp the technology of equipment fault diagnosis preferably.This equipment also is the reliable tools of carrying out all kinds of mechanical fault diagnosis development tests.
Illustrate in greater detail embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is that load is the mechanical fault diagnosis comprehensive experiment table of plant equipment;
Fig. 2 is that load is the mechanical fault diagnosis comprehensive experiment table of generator.
In the accompanying drawing 1, variable-frequence governor (1) is reconciled the working speed of three phase alternating current motor (2), and motor is connected by shaft coupling (3) with the comprehensive experiment table input shaft.The both sides of input shaft are fixing by bearing seat (5).(6) be the transient equilibrium disk that is used for simulating the unbalance dynamic phenomenon, can join different masses on the disk.Input shaft (first) small Spur gear is meshed with second large straight gear (7), and this is to the spot corrosion and the broken teeth fault of gear simulation spur gear.Have three large straight gears of changing at any time as required, one is normal gear, and two are respectively spot corrosion and broken teeth gear in addition.Second has a pair of spiral gear (8) to be meshed with the 3rd.The situation of its quantity and simulated failure is identical with spur gear.The 3rd has a pair of herringbone wheel (9) to be meshed with the 4th.This is the fault that the large-scale herringbone wheel of simulation (being meant that a large-scale herringbone wheel is adding the herringbone wheel that assembles again after processing respectively by two spiral gears man-hour) causes error to cause in processing or when installing to gear.Gear (9) is the processing separately of branch two halves, two groups of pilot holes and fixing threaded hole are arranged on the gear, one group is the herringbone wheel under being used for fixing normal condition, after removing first group of fixed pin, when adopting another group fixed pin, just can simulate owing to process or install the phenomenon of the failure of the inaccurate herringbone wheel both sides spiral gear flank of tooth dislocation that causes.Being risen by input shaft, is removable rolling bearing in first three root axle two end axles bearing.(5) be one of them.One cover standard rolling bearing is respectively arranged, also have bearings such as serious wear, Internal and external cycle spot corrosion in addition respectively.Can change at any time as required.In the 4th axle two end axles bearing is sliding bearing (10).This is mainly used to simulate to bearing and lubricates bad and fault that cause bearing temperature rise so that damage.This inner structure to sliding bearing is the dress sliding bearing sleeve, at big herringbone gear shaft bearings at both ends place dismountable axle sleeve to be installed also in bearing seat.After simulated failure is damaged, only need more renew cover and do not damage axle.This comprehensive experiment table can also be simulated because the fault that the installation aspect is produced.Out-of-size allowed band when for example, the centre distance of simulation pair of engaged gears is installed and the fault that produces; Not parallel and the fault of generation between simulation axle and the axle.The fault that shaft coupling two side shafts produce not on same center line.Axle on the shaft coupling (11) is an output shaft.There are two kinds of load forms this back, and accompanying drawing 1 is depicted as plant equipment load, and this equipment is rolling mill.Gear shaft that passes through on shaft coupling (11) the connection gear seat (12) on the gear (9) rotates, and drives the identical spur gear engagement of a pair of parameter, and produces two thus with the rotation of rotating speed output shaft drive universal drive shaft.Universal drive shaft drives rolling-mill roller and relatively rotates and be rolled sheet metal.Hydrostatic bearing (16) is housed on rolling-mill roller two end axles bearing.This hydrostatic bearing provides condition of work by hydraulic workstation.In this hydraulic system, can simulate faults such as leakage of oil, wearing and tearing, pressure variation.(14) be the rolling mill main body.Pressure transducer (13) is housed on the topping roll bearing seat, is used for monitoring roll-force.Needed vibration, speed, displacement, temperature sensor are installed in the position of (15) on four bearing seats.Shown in the accompanying drawing 2, generator (17) and load controller (18) are the adjustable load of separating of comprehensive experiment table.(4) be the comprehensive experiment table base.
