Modeling lubricating system of reducer of the excavator

This paper presents modeling lubricating system of reducer of the excavator. Network modeling of fluid Dynamics and 3d Computational Fluid Dynamics was used. The problem of fluxes balancing was solved. This paper presents numerical analysis of oil main of planetary reducer. Numerical analysis was made to save equal oil flow rates through outlet ports. Net modeling was made to solve this problem. Oil flow was laminar. The model involves hydrodynamic resistances. Certain resistances were determined by empirical formulae. Other resistances were determine by 3d modeling.
