The prompt
Create a precise parametric 3D CAD assembly of the automated warehouse storage and retrieval system shown in the attached drawing. Follow the reference drawing strictly. Preserve the mechanical layout, component positions, motion directions, and overall proportions. Do not simplify or redesign the mechanism. Coordinate system: X = horizontal travel Y = transverse direction Z = vertical lifting Main components: - Vertical guide column and rack - Lifting carriage - Rack-and-pinion lifting mechanism - Lifting motor - Worm gearbox - Horizontal travel gearbox and motor - Four travel wheels - Horizontal guide rail - Chain transmissions - Roller conveyor - Goods/load - Supporting frame - Bearings, shafts, keys, couplings and fasteners Use these design parameters: L = 900 mm h = 180 mm L1 = 700 mm L2 = 500 mm d3 = 100 mm d8 = 160 mm Vn = 55 m/min Vx = 20 m/min Gn = 130 kg Gd = 100 kg Lh = 21,000 h Lifting gearbox: - Worm gear transmission - Worm starts z1 = 2 - Worm wheel teeth z2 = 17 - Ratio i = 8.5 - Module m ≈ 5 mm - Right-hand worm - Lifting motor ≈ 2.2 kW, 1500 rpm Horizontal travel: - Travel wheel diameter = 160 mm - Travel speed = 20 m/min - Travel gearbox ratio ≈ 40 - Motor ≈ 0.37 kW, 1500 rpm - Four wheels supporting the carriage The lifting mechanism must work as: motor → worm gearbox → output shaft → pinion → rack → vertical carriage movement. The horizontal mechanism must work as: motor → travel gearbox → chain/wheel drive → horizontal carriage movement. The roller conveyor must contain multiple rollers, shafts, bearings, sprockets and chain transmission, with roller axes parallel to Y. Model the worm gearbox as a real mechanical assembly with: - Separate worm shaft - Separate worm wheel shaft - Worm and worm wheel - Bearings - Keys - Seals - Housing and cover - Realistic shaft shoulders and bearing seats Make all major dimensions parametric and editable. Ensure: - Correct rack-pinion and worm-wheel meshing - Correct wheel-rail contact - Realistic mechanical clearances - No component intersections - Realistic shafts, bearings and chain paths - Assembly is suitable for engineering drawings and manufacturing documentation Prioritize mechanical accuracy, dimensional consistency, manufacturability, and similarity to the reference drawing.
