Product Specifications

Technical details and manufacturing context for Hinge Joints

Definition
Hinge joints are critical components in articulated booms that enable controlled rotational movement between adjacent boom sections, allowing the boom to articulate and reach various positions while maintaining structural integrity and load-bearing capacity.
Working Principle
Hinge joints operate on a pin-and-clevis principle where a cylindrical pin passes through aligned holes in two connected parts, allowing rotation around a single axis while preventing movement in other directions.
Common Materials
High-strength alloy steel
Technical Parameters
  • Pin diameter and bore size specifications (mm) Standard Spec
Components / BOM
  • Hinge Pin
    Provides the rotational axis and transfers loads between connected parts
    Material: Hardened alloy steel
  • Clevis
    U-shaped bracket that holds the hinge pin and connects to boom sections
    Material: High-strength steel
  • Bushings/Bearings
    Reduce friction between moving parts and provide wear resistance
    Material: Bronze or polymer composite
  • Retaining Mechanism
    Secures the hinge pin in place (cotter pins, bolts, or locking rings)
    Material: Steel
Engineering Reasoning
0-180 degrees rotational freedom, 15-45 N·m torque transmission, 0.1-0.5 mm radial clearance
Shear stress exceeding 250 MPa in pin material, radial clearance exceeding 1.2 mm, angular misalignment exceeding 3 degrees
Design Rationale: Fatigue failure due to cyclic Hertzian contact stress at pin-bushing interface exceeding 1500 MPa, fretting wear at mating surfaces with relative motion amplitude >50 μm
Risk Mitigation (FMEA)
Trigger Insufficient lubrication causing boundary lubrication regime with coefficient of friction >0.15
Mode: Accelerated adhesive wear leading to 0.8 mm radial clearance increase within 500 operating hours
Strategy: Forced lubrication system with 0.5 L/min flow rate at 2 bar pressure and MoS2 additive concentration of 3% by weight
Trigger Cyclic bending moment exceeding 120 N·m at 2 Hz frequency causing stress concentration factor of 2.8 at fillet radius
Mode: Fatigue crack initiation at pin root with propagation rate of 10^-8 m/cycle leading to fracture within 10^6 cycles
Strategy: Shot peening surface treatment inducing 400 MPa compressive residual stress layer of 0.3 mm depth and radius optimization to maintain stress concentration factor <1.5
