转向油缸上的万向轴承应使用齿轮油进行润滑。‌

转向油缸上的万向轴承在工作期间承受大扭矩和交变载荷,因此需要选择合适的润滑油以确保其正常运作和延长使用寿命。黄油虽然常见,但其韧性较差,难以在轴承中形成良好的油膜,特别是在需要承受大扭矩和交变载荷的情况下。因此,推荐使用齿轮油进行润滑,原因如下:

1、齿轮油的粘度适当‌,能够形成高强度的油膜,这种油膜不会因离心力而从接触面塌陷,从而能够形成良好的弹性动压润滑。

2、齿轮油具有出色的油性和极压性能,这可以确保在高压工况下建立有效的边界润滑膜,保护万向轴承免受磨损。

在实际操作中,如果有齿轮油灌装设备,应定期为万向节加油并检查钢碗的密封性。另外,也可以使用锂基润滑脂进行润滑,结合定期维护工作,分解万向节,清理旧油并重新注入新油进行润滑‌。

综上所述,选择适当的润滑油对于保护转向油缸上的万向轴承至关重要,齿轮油因其优异的性能而成为首选。
