2-Stage Industrial Parallel-Shaft Gearbox Cutaway (10 Bodies)
10-body industrial parallel-shaft speed reducer (total ratio i = 10.67:1) with upper housing cover removed to expose the high-speed pinion shaft, intermediate countershaft, slow-speed output shaft, 4 gears, and 6 roller bearings.
Two-stage parallel-shaft speed reducers are the workhorses of conveyors, cranes, and rolling mills. Removing the upper cast-iron cover reveals the complete 3-shaft drivetrain supported on six rolling-element bearings seated in the split housing bores.
1. Geometry & FEA Mesh
- •10 independent solid bodies: lower cast iron housing, high-speed pinion shaft, Stage 1 driven gear, intermediate pinion shaft, Stage 2 slow-speed bull gear, output shaft, bearing sets, and end caps.
- •Zero CAD Collisions Gate verified across all 10 bodies.
2. Loads & Boundary Conditions
- •Concentric bearing seats, shaft shoulders, and gear tooth tip clearances across both stages.
3. Simulation Results & Findings
- ✓10 gearbox bodies load in the 3D viewport with individual tree controls and physical material properties.
Provides a classic multi-body industrial gearbox benchmark assembly in WebCAE.
