Definition: Refers to the ability of grease↓α’s structural system to resΩ±✔∏ist deformation and flow under mechanic σ ←al shear forces.
① Mechanical stability is ≈✘≥an important performance characterist₹>∑ic of grease and a k↑γ♠ey factor affecting it ↑€s service life.
② The mechanical stability of ↓>σgrease mainly depends on the type o☆® ↑f thickener and the preparation pro☆®cess.
③ Methods for analyziλ€ng the mechanical stability of g₽≤rease include shear stability testing, ★"roll stability testing, a♥±nd grease leakage test& ≈>ing for automobile wh®•€₹eel bearings.
Ø Test Standards:
Ø Method 1: GB/T 269 “Test M★φ♦ethod for Shear Stability of Gr ease”, Equivalent Method∞λ✔φ: ISO 2137-1985;
Ø Method 2: SH/T 0122 “Test"☆® Method for Roll Stabil ↕↓ity of Grease”, Equivale♣<nt Method: ASTM-D1831
