Purpose

This study aims to the influence of grease consistency on oil film thickness, friction coefficient (COF) and wear. A novel Replenishment evaluation model for grease performance is proposed.

Design/methodology/approach

Measurements are conducted using an optical interference test bench and the MTM2 micro-traction machine the oil film thickness and friction coefficient (COF) of lithium-based greases with varying consistencies. And develop a mathematical model for evaluating the back-flow performance of grease, while also quantitatively analyzing its replenishment behavior and anti-wear capabilities.

Findings

Analysis results indicated that greases with lower consistency demonstrate superior back-flow performance and are less prone to starvation. The proposed model effectively captures the relationship between back-flow behavior, COF and wear.

Originality/value

The findings of this research offer valuable insights and practical guidance for the selection of lubricating grease in real-world operating conditions.
