The Digital Model Three-ring Gear Reducer Movement Simulation And Experiment Research

With the continuous improvement of modern mechanization level, the deepeningof the research on gear transmission, which has characteristics of compact structure,large carrying capacity of gear transmission form has attracted extensive attention ofthe industry. Three-ring gear reducer is a form of less tooth differenced planetary geartransmission, with its large transmission ratio, small volume, strong carrying capacity,compact structure, wide range of power and other characteristics, has been widely usedin all walks of life. Internal tooth plate is the key of three-ring gear reducer parts, itsmanufacturing precision directly affect the performance of three-ring gear reducer. Butnow widely used in tooth plate processing scheme has many insufficient, seriouslyaffect the application and promotion of three-ring gear reducer. At the same time, thestructure characteristics of three-ring gear reducer, meshing condition of inner rack,determines the inner tooth plate assembly sequence. To date, there has been noliterature can also put the three-ring gear reducer tooth plate assembly in order to makeit clear, often cannot lead to three-ring gear reducer assembly, correct directly restrictsthe development of three-ring gear reducer.In this paper, the three-ring gear reducer tooth plate processing method, assemblysequence and structure analysis experiments. First of all, according to the condition ofmeshing of three-ring gear reducer, the paper puts forward a new processing scheme ofinner tooth plate, using CAD software UG in adopting new digital modeling of toothplate processing scheme of three-ring gear reducer. Through analyzing the movementof the virtual prototype simulation and processing of the result of simulation showsthat the new scheme satisfy the reduction ratio of inner rack, prove the feasibility ofnew inner tooth plate treatment program; Secondly, through the analysis of thecondition of meshing of three-ring gear reducer, three-ring gear reducer is put forwardin tooth plate assembly sequence related to the input shaft keyway distribution. Theauthor assumes that a number of internal tooth plate assembly sequence, through the comparison of different assembly sequence proves that the tooth plate assemblysequence is related to with the keyway on the input shaft distribution; Then, using UGNX7.0and ANSYS workbench of three-ring gear reducer casing modal analysis,determine the three-ring gear reducer box type vibration frequencies and to use, toprevent the occurrence of resonance system provides an important basis.Finally, thethree-ring gear reducer box body vibration acceleration test experiment was carried out,using Matlab software programming to obtain the vibration acceleration signal ofFourier transform, and draw out of the box body vibration spectrum curve, and thenaccording to the characters of curve analysis of the dynamic performance of three-ringgear reducer gear box.
