According to experimental measurement,the damping factor in torlsional vibration mode shape of damped gear webs could reach over 0.4.It makes the method of real modes in common use to give results whose errors are unaceeptably too large.The author establishes the dynarnlc model of gear system. The model includes pinion,hub and ring ofgear,masscs connected on input and output ends.In this model the tortional vibration of all elements in the system and radial vibration of the palr of gears are considered and...

According to experimental measurement,the damping factor in torlsional vibration mode shape of damped gear webs could reach over 0.4.It makes the method of real modes in common use to give results whose errors are unaceeptably too large.The author establishes the dynarnlc model of gear system. The model includes pinion,hub and ring ofgear,masscs connected on input and output ends.In this model the tortional vibration of all elements in the system and radial vibration of the palr of gears are considered and the principal source of daniping is the damping of viscoelatic materials atteched on webs,which is treated as a torsional damper.Then the author adopts tbe complex vibration mode analyzing technique to deal with this model.Further,the author computcs the dynamic response of tbe damped gear sysem,The calculated results are found to be corresponding to the obscrvations given in some reporis on experiments with damping.

Three adopted tpe of web arrangements are plain, inclined andone-side web respectively. Test results show that the influence of web size variation on natural fre-quencies of thin-rimmed gear structure is larger than the influence of rim size variation. The typesof web arrangements have different influenas on natural frequencies of gear structures. The test re-sults are compared with...

Modal experiments of eight thin-rimmed helical gear structures with different web arrange-ments are carried out in this paper. Three adopted tpe of web arrangements are plain, inclined andone-side web respectively.
