PRESSING DEVICE FOR TENSIONING TWO GEARING ELEMENTS, GEARING PROVIDED WITH A PRESSING DEVICE OF THIS TYPE, AND METHOD FOR OPERATING SUCH A FRICTION GEARING

摘要

The invention relates to a pressing device (9, 10, 11, 14), which comprises two partial pressing devices and which is provided for two gearing elements (1, 2, 3) that roll on one another. The second partial pressing device (14) partially compensates for the force exerted by the first partial pressing device (9, 10, 11). The pressing device (108, 125, 126) is operated with an operating state pressing force characteristic curve which, between a state of rest of the friction gearing and a first operating state, has a slope that differs from that between the first operating state and a second operating state.
