Product Specifications

Technical details and manufacturing context for Drive Shaft/Bearing Assembly

Definition
The Drive Shaft/Bearing Assembly is a critical component of the Tool Arm that combines a rotating shaft with bearing support to transfer torque from the power source to the working end of the arm while maintaining precise alignment and minimizing friction. It enables smooth rotational motion and handles mechanical stresses during operation.
Working Principle
The drive shaft transmits rotational force from the motor or gearbox, while the bearing(s) reduce friction between the rotating shaft and stationary housing, supporting radial and axial loads to maintain alignment and rotational stability within the Tool Arm structure.
Common Materials
Alloy Steel, Bearing Steel
Technical Parameters
  • Shaft diameter and bearing dimensions critical for fit and load capacity (mm) Customizable
Components / BOM
  • Drive Shaft
    Transmits rotational torque through the assembly
    Material: Alloy Steel
  • Bearing
    Supports shaft rotation and reduces friction
    Material: Bearing Steel
  • Housing
    Encloses and supports bearing components
    Material: Steel or Aluminum
  • Seals
    Prevents contamination and retains lubrication
    Material: Rubber or Polymer
Engineering Reasoning
0-6000 rpm rotational speed, -40°C to 120°C temperature, 0-15 kN radial load, 0-5 kN axial load
Brinell hardness drop below 200 HB at 150°C, torsional stress exceeding 400 MPa, radial deflection exceeding 0.1 mm per 100 mm length
Design Rationale: Microstructural degradation of bearing steel (AISI 52100) due to tempering above 150°C, leading to loss of hardness and spalling; torsional fatigue from cyclic loading exceeding endurance limit of 4140 steel (280 MPa)
Risk Mitigation (FMEA)
Trigger Lubricant film thickness reduction below 1 μm due to thermal breakdown at 130°C
Mode: Boundary lubrication leading to adhesive wear and seizure
Strategy: Integrate PTFE-coated retainers and synthetic ester lubricant with 180°C thermal stability
Trigger Misalignment exceeding 0.05° per meter from thermal expansion differential (steel: 11.7 μm/m·°C vs aluminum: 23.1 μm/m·°C)
Mode: Edge loading causing brinelling and premature bearing fatigue
Strategy: Implement self-aligning spherical roller bearings with ±3° angular misalignment capacity
