WHEEL STABILISER

Wheel Stabiliser in truing robot.
The new, patented MD stabiliser module can be incorporated in the Obelisk II truing machine in the same small housing. This set-up allows stabilising without extra handling, wheel buffering or transport of the wheel. The reuslt is a much higher quality wheel with increased lifetime stability.

Stabilising means applying a force (from both sides of the wheel, simultaneous, force closed) to the spokes in the direction of hub. This force sets the spoke elbows in the flange holes of the hub and the nipples in the rim. This same effect occurs when a wheel is used over a long period of time, but, in the case of a wheel that has not been factory stabilised, can result in an untrue wheel or early failure of the wheel.

Stabilising, if used in the correct process sequence, results in more stable, durable wheels. Bicycle manufacturers have been familiar with factors such as those described above for many years. To improve the quality of trued wheels, separate stabilising machines have been placed in wheelbuilding lines. In the traditional systems the wheels are stabilised before a minimum torque is applied to all the spokes. The effect of stabilisin is therefore minimal. In traditional systems, there is always an additional, separate machine that requires higher investment and additional workspace within the factory.

The process steps
First, in the laced wheel, the nipples are rotated by the nipple hands to apply an equal, minimum torque. After the torque has been set and cheked, the wheel is stabilised The final step is the process of actually truing the wheel, within the customerīs desired tolerances for wobble and hop. For all three steps the wheel remains positioned in the wheel axle clamps, so that no additional handling is needed. Software makes it possible to opt for stabilisation or no stavilisation for each run of wheels and the number of stabilising rounds during the truing of the wheel. These factors depend on materials, required wheel quality, production speed and type of wheel.
