Industry-Verified Manufacturing Data (2026)

Drive Hub

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Drive Hub used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Drive Hub is characterized by the integration of Spline Teeth and Mounting Flange. In industrial production environments, manufacturers listed on CNFX commonly emphasize Alloy Steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The central rotating component of a torque limiting clutch that transmits torque from the input to the output while allowing controlled slip when torque exceeds a preset limit.

Product Specifications

Technical details and manufacturing context for Drive Hub

Definition
In a torque limiting clutch, the drive hub serves as the primary torque-transmitting element that connects the input shaft to the clutch mechanism. It's designed to engage with friction plates or other torque-transmitting elements and incorporates features that allow it to disengage or slip when the applied torque exceeds the clutch's calibrated limit, thereby protecting downstream equipment from overload damage.
Working Principle
The drive hub rotates with the input shaft and transmits torque through its engagement surfaces (such as splines, teeth, or friction surfaces) to the clutch pack. When torque exceeds the preset limit (determined by spring pressure or other mechanisms), the drive hub allows relative motion (slippage) between itself and the engaged components, interrupting torque transmission until torque returns to safe levels.
Common Materials
Alloy Steel, Case-Hardened Steel
Technical Parameters
  • Bore diameter for shaft mounting (mm) Customizable
Components / BOM
  • Spline Teeth
    Engages with mating components to transmit torque
    Material: Case-Hardened Steel
  • Mounting Flange
    Provides attachment points for clutch plates or springs
    Material: Alloy Steel
  • Bearing Surface
    Reduces friction during slippage events
    Material: Hardened Steel with Lubrication
Engineering Reasoning
50-500 N·m torque transmission, 0-3000 rpm rotational speed, -40°C to 120°C operating temperature
Shear stress exceeding 350 MPa in spline teeth, surface temperature exceeding 200°C at friction interface, radial deflection exceeding 0.15 mm at bearing surfaces
Design Rationale: Adhesive wear at friction surfaces due to exceeding the static friction coefficient limit (μ > 0.35), torsional fatigue failure from cyclic stress exceeding the endurance limit of 4140 steel (σ_e = 280 MPa), thermal degradation of lubricant film at temperatures above 150°C
Risk Mitigation (FMEA)
Trigger Contaminant ingress (particles > 25 μm) into friction interface
Mode: Abrasive wear leading to increased slip torque deviation exceeding ±15% of setpoint
Strategy: Integral labyrinth seals with 0.05 mm radial clearance and positive pressure purge system at 0.2 bar
Trigger Misalignment exceeding 0.1° angular or 0.3 mm parallel offset during installation
Mode: Premature bearing failure within 500 operating hours due to edge loading
Strategy: Precision ground pilot diameters with h6/H7 fit tolerance and integrated alignment dowels
