Forged Aluminum Gear Hub: Six-Lobe Drivetrain Hub
The forged aluminum gear hub is a disc-shaped drive part in a heavy-motorcycle drivetrain. It is a six-lobe flower-shaped disc with a round central boss and six recesses around it that can be machined into bolt holes or cush-drive rubber seats. Parts like this are used in rear-wheel drives, clutches or transmission mechanisms, transmitting torque while absorbing shock.
Al Forge Tech (AFT) has produced heavy-motorcycle transmission hubs and handlebar clamps in 6061-T6, 2014-T6 and 7075-T6, including forging, machining and anodizing. The six-lobe shape is closed-die hot forged in one operation so grain flow runs continuously through each lobe and the central boss; after heat treatment, the center bore, bolt holes and mating faces are turned and CNC-machined.

よくある質問
Which aluminum alloys are used for gear hubs, and how are they chosen?
AFT’s heavy-motorcycle transmission hubs and handlebar clamps have used 6061-T6, 2014-T6 and 7075-T6. 6061-T6 balances machinability and corrosion resistance; 2014-T6 offers higher strength for heavier loads; 7075-T6 is a high-strength alloy for designs demanding maximum strength and lightness, but needs anodizing for corrosion resistance. The choice depends on load, corrosion requirement and cost.
How is bolt-hole indexing ensured on the hub?
Bolt-hole indexing and pitch circle diameter determine how the hub assembles to sprockets or wheel hubs. After heat treatment, AFT machines all bolt holes in one CNC setup so indexing shares one datum, then measures pitch circle diameter, indexing and hole size on Zeiss CMM.
How does a forged aluminum Forged Aluminum Gear Hub compare with casting or machining from billet?
Forging shapes aluminum in the solid state under pressure, so the grain flow follows the part contour and the porosity and shrinkage common in castings are avoided. Compared with machining from solid billet, a near-net-shape forging removes less material and shortens machining time. For a Forged Aluminum Gear Hub under repeated loads, forging balances strength and weight; the final choice still depends on design loads and volume.
Is heat treatment for the Forged Aluminum Gear Hub done in-house?
Yes. Al Forge Tech operates 8 T4 solution treatment units and 7 T6 artificial aging units on site, so the Forged Aluminum Gear Hub can be solution treated, quenched and aged in the same facility before machining and inspection. Keeping heat treatment in-house removes inter-plant transport, reduces lead-time risk and keeps lot traceability within one quality system. Parameters are set according to the alloy grade and your specification.
Can the Forged Aluminum Gear Hub be anodized or given other surface finishes?
Yes. Al Forge Tech offers anodizing (including hard anodizing), shot blasting, vibratory finishing, e-coating and painting, plus pickling and ultrasonic washing lines to clean parts after machining. Please note the finish type and film thickness on the drawing so machining allowances and cosmetic standards for the Forged Aluminum Gear Hub can be evaluated together.
