Dynamic characteristics of the rack and pinion lift mechanism of the combined command cabin

Abstract This paper presents a novel approach to accurately simulate the dynamic characteristics of rack and pinion lifting mechanism while accounting for coupling effect meshing tooth pair stiffness grease in real-world environments. A structure-grease model is established based on deformation coordination conditions meshing. The incorporates term time-varying pinion. By analyzing combined command cabin using this model, we find that total gear teeth lower when transient thermoelastic flow considered. Furthermore, value decreases as normal force at point decreases. research reveals worst lubrication are typically found wheel near base circle, where film temperature rise highest, pressure thickness thinnest.
