The aim of this research paper is to simulate the process of gear meshing in the planetary gear system (PGT) of CNC bending machine to evaluate the friction coefficient, friction force, and wear rate of EN24 material. EN series of steel is typically used for gear manufacturing. The PGT is capable of transmitting huge torque and provides high performance along with huge reduction ratio. It is used on a grand scale in many applications. Effective meshing is observed at the sun and planet gear interface only. Tests are performed on a cylinder-on-disk machine with varying loads from 60 to 110 N for time duration of 5 min at 1250 rpm. The outcomes elucidate that the friction coefficient fluctuates with time and normal load. From experimental inspection, it is observed that the friction coefficient increases with rubbing time and after that remains constant for a rest period. From experimental investigation, it is observed that the friction coefficient and wear increase with an increase in normal load. It is observed that the presence of carbon content leads to fluctuation in wear rate. Wear measurement test was carried out for EN24 materials by rubbing different cylinders on EN-31 disk.

本研究的目的是模拟CNC折弯机行星齿轮系统（PGT）中的齿轮啮合过程，以评估EN24材料的摩擦系数，摩擦力和磨损率。EN系列钢通常用于齿轮制造。PGT能够传递巨大的扭矩，并提供高性能以及巨大的减速比。它在许多应用中被大规模使用。仅在太阳齿轮和行星齿轮的界面处观察到有效啮合。测试是在磁盘负载为60 N至110 N的变化的磁盘机上进行的，持续时间为12分钟（5分钟），转速为1250 rpm。结果表明，摩擦系数随时间和正常载荷而波动。从实验检查来看 可以观察到，摩擦系数随摩擦时间而增加，此后在一段时间内保持恒定。从实验研究中可以看出，摩擦系数和磨损随着法向载荷的增加而增加。观察到碳含量的存在导致磨损率的波动。通过在EN-31圆盘上摩擦不同的圆柱体，对EN24材料进行了磨损测试。
