Influence of Teeth Manufacturing Tolerances of Cylindrical Geared Wheels on GearOperating Characteristics Based on Spinner Stretching Apparatus

摘要

In the paper, issues related to the errors and inaccuracies resulting from improper operation?of the drive system of the stretching apparatus of a ring spinner are discussed. The aim of the?paper was an analysis of a design solution for the driving system of a ring spinner and its?operating behaviour influencing the quality parameters of the fiber jet. In the paper, modelling?of the involute teeth shape by means of a BEASY package was done. Based on the model?prepared, an assessment of the sensivity of geometrical teeth outline on particular dynamical?quantities for the gear of the stretching apparatus was performed. An improvement in the?parameters of operating of the spinner can be achieved via changing of the design characteristics?of elements of the driving system; in particular, modification of the teeth shape was?considered. Within the scope of the work, numerical analyses of the meshing geared wheels?were conducted taking into consideration the unevenness of operating of the drive system as?well as load distribution acting along the line of action. In the paper, the boundary element?method was utilised for evaluation of the load distribution in relation to spectral analysis?connected with the unevenness of the fibers’ jet mass.
