Variaattoritoiminnolla varustettu kitkaplaneettavaihde ja menetelmä sen käyttämiseksi

摘要

The invention relates to a frictional planetary gear with variator action. A first set of planet wheels roll along the internal rolling surface of a driving ring. A second set of planet wheels roll along a fixed rotation roller path. The planet wheels have pins thereof supported on planet flanges. The planet wheels of the second set are supported by means of a resilient central element for radial displacement. The fixed rotation roller path has a diameter which is adjustable, enabling an easy and expedient regulation of the transmission ratio even at high transmission ratios.
