Lukienko L.V., Isaev V.V. Determination of hardness values of the transfer mechanism to assess the loading of heavy-duty production machines

Determination of hardness values of the transfer mechanism to assess the loading of heavy-duty production machines

Lukienko L.V., Isaev V.V.

The paper presents the results of analytical determination of gear rigidity index of the production machine feeding mechanism to estimate dynamic loading of a rack-and-pinion transfer system. The APM WinMachine software is used for this purpose. The analysis of the results shows that rigidity of rack-and-pinion and pin wheel considerably outdoes the rigidity of feeding mechanism gears. The teeth rigidity of the driving wheel of a rack-and-pinion transfer system depends on the load point and changes to 23.5%. The rigidity of a gear – pin wheel transmission is 32.27% higher than that of a gear – rack-and-pinion transmission system. The validity of received results is confirmed by the acceptable similarity of certain values of equivalent tension with the previous research results. The difference in values of equivalent tension doesn’t exceed 12.3%. It is advisable to use a three-mass dynamic model for further research work.

Keywords: modeling, rigidity index, feeding mechanism.
