通过螺旋槽和直槽结构的水润滑橡胶合金轴承摩擦学性能对比实验,研究螺旋槽结构对水润滑轴承的润滑特性及泥沙和杂质排泄能力的影响,结果表明螺旋槽结构的水润滑橡胶合金轴承摩擦学性能优于直槽,更容易形成弹性流体动压润滑,降低摩擦磨损,具有良好的泥沙和杂质排泄能力,对延长使用寿命和保护设备正常运行具有很好的作用。
The effect of spiral groove structure on properties and silt-impurity excretion ability of water lubricated bearings lubrication is studied through comparison experiments on tribology properties of spiral groove and straight groove water lubricated rubber bearings.The results show that the tribological properties of spiral groove water lubricating rubber bearings are superior to the straight groove's.The spiral groove water lubricating rubber bearings is easier to form elastic hydrodynamic lubrication,reduce friction and wear,have good capacity of silt and impurity discharge,and have very good effect on extending the service life and protecting the normal operation of the equipment.
