<p>A drive system for a domestic appliance provides inner and outer coaxial drive outlets operative at different speeds and comprises an active limb, which incorporates an electric drive motor and a shaft driven by said motor and coupled to the inner drive outlet to drive it at a selected speed. The system also includes a passive limb which incorporates a rotary component; the two limbs being mounted in fixed relationship to one another. A first speed reduction mechanism couples the shaft to the rotary component of the passive limb and a second speed reduction mechanism couples the said rotary component to the outer drive outlet. Conveniently, the rotary component comprises a further shaft, disposed substantially parallel to the driven shaft of said motor, and both limbs of the system are rigidly mounted to, and supported by, a common framework of support members. Both speed reduction mechanisms are typically belt driven, and may provide identical reductions.</p> |
