“…Herringbone tooth planetary transmission is widely used in the transmission field of armament equipment, shipbuilding heavy industry, aviation and automobile because of the advantages of reliable work, smooth transmission, large load-bearing capacity, compact structure, high transmission efficiency, high degree of overlap and small axial force [1]. Herringbone gears have a certain helix angle, traditional finishing processes such as grinding, grinding and hand polishing can achieve the accuracy requirements of mechanical parts, but their efficiency is low and the cost is high, abrasive flow machining as a new surface treatment method, because of its high processing accessibility to the internal surface of through-hole type parts and complex curved surfaces have a good surface treatment effect [2].…”

The Eulerian-Eulerian method is used to numerically simulate herringbone teeth using the precision machining technique of abrasive flow. The effects of inlet velocity and abrasive concentration factors on abrasive flow machining are investigated separately for numerical analysis to reveal the effects of dynamic pressure and wall shear on abrasive flow machining under different machining parameters. The simulation results show that increasing the inlet velocity can improve the processing efficiency and the processing effect of abrasive flow processing. Increasing the abrasive concentration increases the processing cost and predicts a weakening of the abrasive flow, allowing for the use of lower concentrations of abrasive flow for actual processing.
