# ConveyAI — Preliminary Engineering Report Project: Input required Generated: 2026-10-16T15:26:15.190Z | Model 1.0.0 NOT RELEASED FOR PROCUREMENT OR FABRICATION ## Design inputs ## Open numeric inputs Loaded conveying length (m): input required Belt width (mm): input required Belt speed (m/min): input required Product length along travel (mm): input required Gap between products (mm): input required Parallel product lanes (count): input required Mass per product (kg): input required Belt mass per metre (full width) (kg/m): input required Carryway sliding coefficient (—): input required Return sliding coefficient (—): input required Additional measured resistance (N): input required User-approved design multiplier (—): input required Drive efficiency (0–1): input required Belt hinge pitch (mm): input required Sprocket teeth (count): input required Motor operating speed (rpm): input required Derated allowable belt pull, full width (N): input required Solid round shaft diameter (mm): input required Shaft bearing span (mm): input required Single central radial shaft load (N): input required Shaft elastic modulus (MPa): input required Approved equivalent stress limit (MPa): input required Wear strip expansion coefficient (1/K): input required Unrestrained strip segment length (mm): input required Rise from assembly temperature (K): input required Product width across travel (mm): input required Required clearance each side (mm): input required Minimum rollers under one product (count): input required Approved roller load factor (—): input required Derated allowable load per roller (N): input required ## Preliminary family direction Path geometry required before family selection. No brand, material grade or part number is approved. Temperature, cleaning chemistry, friction, strength derating and food-contact evidence are mandatory manufacturer checks. ## Calculation schedule Theoretical product capacity: Input required Formula: 1000 v × lanes / (product length + gap) Scope: Uniform spacing; no stoppages, slippage or accumulation. Theoretical mass throughput: Input required Formula: capacity × product mass × 60 Scope: Unit products; not a bulk-material volumetric model. Product line mass: Input required Formula: 1000 × lanes × product mass / (length + gap) Scope: Uniform product spacing. Product mass on carrying run: Input required Formula: line mass × conveying length Scope: Average uniformly distributed product loading. Design belt pull: Input required Formula: K × [g L ((q + mb) μc + mb μr) + Fextra] Scope: Horizontal straight conveyor, sliding carry and return, steady motion. K is user supplied; acceleration, curves, incline and accumulation require a separate model. Geometric pitch diameter: Input required Formula: p / sin(π / Z) Scope: Ideal equal-pitch hinge polygon. Tooth profile and outside diameter remain manufacturer-specific. Mean drive shaft speed: Input required Formula: 1000 v / (p Z) Scope: One revolution advances Z pitches. Chordal instantaneous speed is not constant. Reference drive torque: Input required Formula: F × Dp / 2000 Scope: Pitch-circle reference; verify peak polygonal torque and start-up separately. Drive input power: Input required Formula: F v / (60000 η) Scope: Continuous mechanical estimate; not a motor nameplate selection or thermal/start check. Nominal gearbox ratio: Input required Formula: motor rpm / shaft rpm Scope: Verify available ratios, efficiency and actual motor slip. Belt pull utilization: Input required Formula: 100 F / allowable full-width pull Scope: User-supplied derated allowable rating; utilization below 100% is only one necessary check. Shaft bending stress: Input required Formula: 32 (W L / 4) / (π d³) Scope: Solid round shaft, simple supports, one central point load. Excludes self-weight, keyway, overhang and fatigue. Shaft torsional shear: Input required Formula: 16 (T × 1000) / (π d³) Scope: Solid round shaft; no keyway or stress concentration. Equivalent static stress: Input required Formula: √(σ² + 3τ²) Scope: Ductile-material static von Mises screen only; no fatigue approval. Static stress utilization: Input required Formula: 100 σeq / allowable stress Scope: Allowable must include the engineer-approved basis. Not a shaft release. Shaft centre deflection: Input required Formula: W L³ / (48 E I); I = π d⁴/64 Scope: Same simply supported central point-load model; compare with belt-maker limit. Free wear strip expansion: Input required Formula: α L ΔT Scope: Unrestrained segment expansion only. Mounting gaps require end restraint/tolerance review. Guide opening: Input required Formula: product width + 2 × clearance Scope: Straight product envelope only; curves, tilt, guides and tolerances need review. Static design load per supporting roller: Input required Formula: product mass × g × K / supporting rollers Scope: Equal load sharing assumed. Verify worst-position distribution, impact and bearing life. Roller load utilization: Input required Formula: 100 load / derated allowable roller load Scope: Rating must match actual span, speed, material and environment. ## BOM — unapproved specification schedule Modular belt assembly | Specification required | Quantity required | Source required Drive sprockets | Specification required | Quantity required | Source required Idle sprockets | Specification required | Quantity required | Source required Drive shaft | Specification required | Quantity required | Source required Idle shaft | Specification required | Quantity required | Source required Bearing assemblies | Specification required | Quantity required | Source required Motor and gearbox | Specification required | Quantity required | Source required Carryway wear strips | Specification required | Quantity required | Source required Return supports | Specification required | Quantity required | Source required Guide rails and brackets | Specification required | Quantity required | Source required Frame and supports | Specification required | Quantity required | Source required Conveyor change parts | Specification required | Quantity required | Source required Guards and safety controls | Specification required | Quantity required | Source required ## Approval and verification Reviewer: input required; approval date: input required; release status: NOT RELEASED Confirm manufacturer ratings, application-specific safety, fatigue, start/stop loads, guarding, installation and compliance before release. No standards compliance is inferred from these calculations. ## References HabasitLINK Engineering Guide, 6031 EN (2021 document): https://www.habasit.com/-/media/Project/Habasit/NewWebsite/Downloads/Products/Plastic-modular-belts/6031BROMOD-en0421HQR.pdf Intralox engineering manuals: https://www.intralox.com/resources/engineering-manual ISO 12100:2010 — risk assessment and risk reduction: https://www.iso.org/standard/51528.html ISO 14120:2015 — guards: https://www.iso.org/standard/59545.html ASME B20.1-2024 — conveyors and related equipment: https://www.asme.org/codes-standards/find-codes-standards/b20-1-safety-standard-conveyors-related-equipment
