Grinding rollers drive arrangement for a vertical mill

摘要

Grinding rollers drive arrangement (20) for a vertical mill (1), comprising:a) a pivot lever (40) with a central longitudinal axis (a2) and along this a first end portion (41) and a second end portion (42),b) a roller (30), which is rotatably mounted on the first end portion (41) of the pivot lever (40) is arranged and which, for rolling engagement with a grinding plate (10) is provided,c) a transmission (50) with a gear housing (51), a transmission input (52) and a transmission output (53), whereind) the transmission (50) to the second end portion (42) of the pivot lever (40) is arranged and the transmission output (53) with the milling roller (30) is connected in rotary drive,e) of a drive (60) with a drive housing (61) and a drive gear (63), the with the transmission input (52) is connected in rotary drive, andf) a bearing device (70) which, on a stationary base (b) is to be supported and which has a pivot bearing (72), by means of which the pivot lever (40) is pivotable, so that the milling roller (30) to the grinding plate (10) towards and away from said is movable,g) the gear housing (51) to the second end portion (42) of the pivot lever (40) is non-rotatably supported, characterized in thath) the drive housing (61) in a rotationally fixed manner on the gear housing (51) is supported and a pivot axis (a3) of the pivot bearing (72) by the gear (50) extends, so that the drive (60) and the transmission (50) for with the pivot lever (40) are mounted to pivot.i) the transmission (50) arranged symmetrically with respect to a longitudinal center axis (a2) of the pivot lever (40) is arranged, so that the longitudinal center axis (a2) of the pivot lever (40) is independent of a pivoting of the pivot lever (40) coincides with a longitudinal central axis (a4) of the transmission (50), and whereinn="14"j) of the drive (60) is symmetrical with respect to the longitudinal center axis (a2) of the pivot lever (40) is arranged, so that the longitudinal center axis (a2) of the pivot lever (40) is independent of a pivoting of the pivot lever (40) coincides with a longitudinal central axis (a5) of the drive (60) is.
