  • Patent number: 4982617
    Abstract: TransmissionIn conventional transmissions utilized, for example, in rolling mill facilities, the shifting procedure is cumbersome and time-consuming. The shifting process is to be simplified in the novel transmission.The multiple-speed, e.g. two-speed transmisssion (1) exhibits two pinions (2, 3) rotatably supported on a motor-driven input shaft (5), of shifting speeds I and II, for driving two gear wheels (6, 7) non-rotationally arranged on an output shaft. The pinions (2, 3) can be coupled selectively with the input shaft (5) by means of the hydraulic clamping sleeves (10) of two friction clutches (8, 9).The transmission is especially suited for use in rolling mill drive mechanisms.
