Overview

Computational modeling study reveals optimized spider pin profiling expands liquid lubrication zones in wind turbine planetary gears, suggesting improved bearing durability under extreme loads.

Key Points

To develop a thermoelastic hydrodynamic (TEHD) lubrication model to evaluate bearing performance and prevent contact wear in high-power wind turbine planetary gears.
Formulated a coupled numerical algorithm integrating fluid film lubrication equations, heat transfer thermodynamics, and structural elasticity theory.
Simulated spider pin hydrodynamic bearings under extreme loading conditions to compute pressure distributions, clearances, friction moments, and elastic deflections.
Evaluated the effect of geometric profiling on the spider pin support surface to reduce mixed lubrication regimes.
Determined operational thresholds under extreme loads, characterizing critical minimum oil-film clearances, peak pressures, and localized elastic deformation zones.
Demonstrated that strategically profiling the spider pin support surface expands the full fluid-film lubrication zone while minimizing mixed friction areas.
