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（TR Gel-Lube）的摩擦学特性。 TR Gel-Lube在基液中含有10-40%的酰胺型胶凝剂，能够在胶凝剂的熔点下从凝胶态反复转变为液态。进行高压流变测试是为了表征基础油和 TR Gel-Lube 随压力和温度变化的行为。 TR Gel-Lube 对球轴承疲劳寿命的影响是通过使用推力球轴承进行的系统测试进行的。 TR Gel-Lube 的 L10 寿命测试结果表明，TR Gel-Lube 的寿命比传统润滑脂更长。该结果是根据油膜形成进行研究的。研究发现，胶凝剂对润滑性能起着关键作用。提出了一些机制，例如吸附膜形成和固体状形成。
