Abstract

The influence of the type of motion friction (sliding/rolling) on the behavior of antiwear additives of lithium grease has been investigated. The tests of plastic lubricant on wear under conditions of sliding friction on a four-ball friction machine (FBFM-1) and as a part of a rolling bearing have been carried out. The multidirectional influence of additives on tribological properties of plastic lubricants is shown. Introduction of detonation nanodiamonds into lithium plastic lubricants (PLs) in concentration of 0.3% by mass in conditions of rolling friction leads to decrease of friction coefficient in relation to basic PLs by 2 times and increase of relative life. In conditions of sliding friction the antiwear properties are improved by 1.7–1.9 times. Addition of tricresyl ether of orthophosphoric acid (TKF) to lithium PLs in rolling friction conditions leads to increase of friction coefficient by 3.65 times and decrease of relative life, and in sliding friction conditions increases antiwear properties by 1.9 times. The results of research allow us to pick the optimum composition of additives depending on working conditions of a friction unit.

运动摩擦类型对抗磨添加剂性能影响的研究

研究了运动摩擦类型（滑动/滚动）对锂基润滑脂抗磨添加剂性能的影响。在四球摩擦机（FBFM-1）上进行了塑料润滑剂作为滚动轴承部件在滑动摩擦条件下的磨损试验。揭示了添加剂对塑料润滑油摩擦学性能的多向影响。在滚动摩擦条件下，将质量浓度为0.3%的爆轰纳米金刚石加入到锂塑料润滑剂中，其摩擦系数比碱性锂塑料润滑剂降低了2倍，相对寿命提高了2倍。在滑动摩擦条件下，其抗磨性能提高了1.7 ~ 1.9倍。在滚动摩擦条件下，加入正磷酸三甲醚（TKF）可使锂PLs的摩擦系数提高3.65倍，相对寿命降低；在滑动摩擦条件下，其抗磨性能提高1.9倍。研究结果使我们能够根据摩擦装置的工作条件选择最佳的添加剂组成。
