影响牙轮钻头轴承系统寿命的因素很多,除轴承结构、材料、加工工艺以及可靠的密封外,采用卓有成效的添加剂以减小摩擦磨损,也是提高轴承系统寿命的关键措施之一。因此,我们选用“万灵霸”添加剂配合在钻头现用润滑脂中进行模拟试验,对比其抗磨损性能,以期提高牙轮钻头轴承系统的寿命。试验结果表明,加入“万灵霸”全能高效添加剂后,平均减小磨损20.9％,证明该添加剂是有效的,不言而喻,在其它同类恶劣工况下使用该添加剂也必然有效。 一、“万灵霸”添加剂对比试验 1.试验目的 通过试验,对比分析现用钻头润滑脂加入“万灵霸”添加剂前后的抗磨损性能,作出评价。 2.试验方法
There are many factors that affect the life of cone bit bearing system. In addition to the bearing structure, materials, processing technology and reliable sealing, the use of effective additives to reduce friction and wear, but also to improve the life of the bearing system, one of the key measures. Therefore, we use the “Wan Ling Pa” additive with the drill in the existing grease simulation test, compared with its anti-wear performance, in order to improve the life of roller cone bearing system. The test results show that the addition of “Wan Ling Ba” all-around high-performance additives, the average wear reduction of 20.9%, proved that the additive is effective, it goes without saying, in other similar adverse conditions using the additive inevitable. First, the “Wan Ling Pa” additive comparison test 1. Objectives of the test Through comparative analysis of the existing drill grease added “Wan Ling Pa” additive before and after the anti-wear performance, make an evaluation. 2 test methods
