本文研究了热可逆凝胶润滑剂(TRGel-Lube)在弹流润滑条件下的特性。TRGel-Lube是一种润滑剂，由基液和凝胶剂组成。TRGel-Lube能够反复地在其凝胶剂的熔点将凝胶状态转变为液体状态。此外，TR-Gel-Lube还具有良好的摩擦学性能、抗蒸发性能等。本文介绍了弹流润滑油膜厚度特性、入口区域的贫油现象和弹流润滑牵引力特性的研究。结果表明，与普通润滑脂相比，该润滑剂具有较低的弹流阻力、较厚的弹流润滑油膜厚度和良好的弹流润滑油膜形成稳定性。
This study investigates about the characteristic of the thermo-reversible gel-lubricant (TR Gel-Lube) under elastohydrodynamic lubrication (EHL) conditions. TR Gel-Lube is the lubricant, which consists of base fluid and a gel agent. TR Gel-Lube is repeatedly able to change gel-state to liquid-state at the melting point of its gel agent. Moreover, TR Gel-Lube has good tribological properties, anti-evaporability and so on. This paper describes about investigation of the EHL oil film thickness characteristic, the oil starvation at EHL inlet region and the EHL traction characteristic. It was observed that TR Gel-Lube had low EHL traction, thick EHL film thickness and good stability of EHL oil film formation compared with conventional greases.
