Low-noise wheelchair aluminum alloy hub

The sound of a wheelchair in motion is often the background noise to its user's dialogue with the world. Yet low-noise aluminum alloy hubs are redefining this mobility experience with their quiet strength.The secret to the aluminum alloy hub's silence lies in the precise collaboration of material and craftsmanship. Aviation-grade aluminum undergoes precision CNC machining, with the interface between hub and spokes controlled to an error margin of just 0.02mm, minimizing vibration noise from friction. High-purity bearing steel, paired with specialized lubricant, suppresses rotational friction to below 30 decibels—equivalent to the ambient sound in a library, barely perceptible to others.Lightweight design is another advantage. Compared to traditional steel components, aluminum alloy hubs of the same size reduce weight by 40%, cutting driving energy consumption while lessening impact noise from inertia. Hollowed spoke designs maintain strength while cleverly channeling airflow, eliminati…
