Abstract:

In order to solve the return difference problem of traditional gear pairs,the factors influencing the errors in the processes of design,manufacture and installation are quantitatively calculated.Then,by taking into account the influences of tooth thickness deviation,radial pulsation,center distance deviation and temperature on gear deformation,a design method of the metal rubber compound gear pair with automatic deformation compensation is proposed.Moreover,on the basis of ABAQUS finite element analysis,the influences of high and low temperatures on the gear deformation are calculated,and the gear deformations at the high and low temperatures as well as the preloading of theoretical center distance are obtained.Finally,the vibration responses of the metal and compound gear pairs under different preloading are tested.The results show that ( 1) with the increase of the preloading,the vibration acceleration decreases first and then increases; ( 2) the preloading has a great influence on the metal gear pair but a little influence on the compound gear pair,and with the increase of the preloading,the improvement effect of the compound gear pair tends to become more obvious than that of the metal gear pair; and ( 3) the optimal preloading obtained by tests accords well with the calculated result,which verifies the correctness of simulation analysis.
