研究了一种新型热可逆凝胶润滑剂（TR凝胶润滑剂）的摩擦学性能。TR凝胶润滑油在基液中包含10-40%的酰胺型胶凝剂，能够在胶凝剂的熔点下重复地将相从凝胶状态改变或转化为液体状态。进行高压流变试验以表征基础油和TR凝胶润滑油作为压力和温度的函数的行为。通过推力球轴承系统试验，研究了TR凝胶润滑剂对球轴承疲劳寿命的影响。TR凝胶润滑脂的L10寿命试验结果表明，其使用寿命比常规润滑脂长。这一结果是从油膜的形成来研究的。结果表明，胶凝剂对润滑性能起着关键作用。提出了吸附成膜和类固体形成等机理。
The tribological properties of a new and unique thermoreversible 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 repeatedly alter or convert phase 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 bearing fatigue life was carried out by systematic tests using thrust ball bearings. The results of L 10 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.
