REDUCTION GEAR FOR ROTATABLE MECHANISM OF CRANE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: reduction gear has planet gear and gear transmission. The gear transmission connects the output shaft with the planet gear and is cylindrical and two-step. One of the toothings of the gear unit of the two-step gear transmission engages central driving gear having outer teeth and the other one engages the central wheel of the transmission. Each of the units of the gears of the cylindrical and planet transmission includes shaft whereto one of the toothing is rigidly secured and the other is mounted on the shaft to permit the shaft to be detached, rotated and fixed. The central wheel of the planet gear is rigidly secured in housing 1, and the carrier of the unit of the satellites is coupled with the output shaft. EFFECT: improved design. 5 cl, 3 dwg
