Based On The Simulation Study Of Gear Failure Of ADAMS Metallurgical Crane Reducer

As an important part of the metallurgical crane equipment,the reducer is an important mechanism for achieving motion transformation and power transmission of mechanical equipment,where the performance of the gear component will directly affect the reliability and safety of the equipment.The fault study of the gear gear is important in ensuring the safe operation of the equipment and avoids the occurrence of accidents.This paper uses virtual origin technology to establish a high-speed stage pinion,a genuscular crack,breaking,breaking,and dynamic simulation,and dynamic simulation,the simulation model is verified by comparing simulation results and theoretical values.Positiveness.After the model verification is successful,the simulation studies the vibration characteristics of high-speed stage meshing force under different levels of high-speed small gears and different degrees of composite fault conditions,and propose a gear mesh signal identification method.The main research contents of the paper are as follows:(1)Use Solid Works software to model and assemble a metallurgical crane reducer,importing it into ADAMS software for rigidly flexible coarction model and kinetics,and through axial speed,load torque,and reducer dynamics Aspect proofs the correctness of the model.(2)Established a high-speed union gear tooth cracks,different degrees breaking and wear single gear failure rigidity,the simulation comparison draws: 1)As the fault is aggravated,the high speed grade gear is engaged in the vertical direction.The force fluctuation range will increase,in which the breakage range is the largest.2)The amplitude of the multiplication decreases as the frequency increases,and the frequency range of the fault will increase.3)When the gear fails,the high-speed gear meshing frequency and the double frequency of the two frequency are rising,and the corresponding frequency amplitude will increase as the fault is increased.(3)Established a high-speed union gear tooth crack wear,different degrees of breaking wear composite gear failure rigidity,simulation comparison: 1)When the root crack-wear composite fault and broken teeth When the wear composite fault,the high-speed gear meshing frequency and the double frequency of the frequency of the frequency are greatly improved,and then the magnitude range is smaller as the degree of fault is increased.2)When the crack gear is abrasion fault,the high-speed gear engagement frequency and the double frequency combination amplitude are rising: when the wear gear is worn,the high speed stage gear meshing frequency and the magnitude of the frequency are increased.The edge frequency is reduced.(4)Based on the above studies,the high-speed stage gear is normal and the high-speed gear vertical direction of the single gear failure is simulated,and the combination of the set of empirical modal decomposition,sample entropy and ultimate learning machine is established.The simulation data under each operating condition is compared with the combination of the collection experience modified decomposition,sample entropy,and instructional neural network.As a result,it has further verified that the ultimate learning machine has more than the gear meshing signal.High recognition accuracy.
