The tribological properties of a new and unique thermo-reversible Gel-Lubricant (TR Gel-Lube) were investigated. TR Gel-Lube, which includes 10-40% of amide type gelling agent in base fluid, is able to repetitive change from gel-state to liquid-state at the melting point of the gelling agent. High-pressure rheological tests were performed in order to characterize the behavior of base oil and TR Gel-Lube as a function of pressure and temperature. The effect of TR Gel-Lube on ball bearings fatigue life was carried out by systematic tests using thrust ball bearings. The results of L10 life tests of TR Gel-Lube showed a longer life than the conventional greases. This result was investigated from the oil film formation. It was found that the gelling agent played a key role in the lubricating properties. Some mechanisms such as adsorbed film formation and solid like formation are proposed.

研究了一种新型独特的热可逆凝胶润滑剂(TRGel-Lube)的摩擦学性能。在基液中含有10-40%的酰胺类胶凝剂的TrGel-Lube，能够在胶凝剂的熔点重复从凝胶状态到液体状态的变化。进行了高压流变性试验，以表征基础油和TrGel-Lube在压力和温度下的行为。采用推力球轴承进行了系统试验，研究了tr凝胶润滑剂对球轴承疲劳寿命的影响。TR Gel-Lube润滑脂的L10寿命试验结果表明，该润滑脂的使用寿命比传统润滑脂要长。这一结果是从油膜形成的角度进行的。结果表明，胶凝剂是影响其润滑性能的关键因素。提出了吸附成膜、类固体形成等机理。
