Product Specifications

Technical details and manufacturing context for Pivot Housing

Definition
The Pivot Housing is a critical component of the Boom Base Section that provides a secure enclosure and mounting structure for the pivot mechanism, enabling rotational movement while maintaining structural integrity and alignment.
Working Principle
The housing provides a rigid frame that contains bearing surfaces and mounting points for the pivot assembly, allowing controlled rotation of connected components while distributing loads and preventing misalignment.
Common Materials
Cast Steel
Technical Parameters
  • Overall dimensions including bore diameter, mounting hole patterns, and wall thickness specifications (mm) Standard Spec
Components / BOM
  • Mounting Flange
    Provides attachment points to the Boom Base Section structure
    Material: steel
Engineering Reasoning
0-150 kN·m torque, -40°C to 120°C temperature
Material yield strength exceeded at 180 kN·m torque or 150°C thermal expansion exceeding 0.5 mm clearance
Design Rationale: Plastic deformation due to torsional stress exceeding ASTM A36 steel yield strength of 250 MPa, or thermal expansion coefficient mismatch (steel α=11.5×10⁻⁶/°C vs bearing α=23×10⁻⁶/°C) causing binding
Risk Mitigation (FMEA)
Trigger Corrosive environment with chloride concentration exceeding 500 ppm
Mode: Stress corrosion cracking initiating at weld seams
Strategy: 316L stainless steel construction with post-weld heat treatment at 1050°C for 2 hours
Trigger Cyclic loading at 5-15 Hz frequency matching natural frequency of 12 Hz
Mode: Resonance-induced fatigue fracture at stress concentration points
Strategy: Damping ratio increased to 0.15 through constrained layer viscoelastic inserts

Frequently Asked Questions

What is the primary function of a pivot housing in machinery?

The pivot housing serves as a structural component that securely houses and supports the pivot mechanism within the Boom Base Section, enabling controlled rotational movement while maintaining stability under heavy loads.

Why is cast steel used for pivot housing construction?

Cast steel provides exceptional strength, durability, and impact resistance required for heavy machinery applications. It withstands continuous stress, vibration, and environmental factors while maintaining dimensional stability.

How does the mounting flange integrate with the pivot housing?

The mounting flange is a critical component of the pivot housing assembly that provides secure attachment points for connecting to other structural elements, ensuring proper alignment and load distribution throughout the machinery system.
