Overview
This page is to get a better understanding of the engineering and design requirements for the wheel drive assembly.
Shaft Load Bearing Capacity
Currently a 1-7/8" shaft is used on the LifeTrac III. Analysis is required to determine if it is strong enough while using standard carbon steel
Shaft Torsion Limit
Analysis required for using a single g8 bolt and 2 bolts, with 1-7/8 shaft
Analysis required for shear limit using 3" shaft with 2 g8 bolts, 1". This is for scaling analysis of bulldozer. Goal: 16,000 lb of pushing force for prototype 1 using same design with jackshaft
