MULTIFLOW GEARING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: gearing comprises housing, input and output shafts whereto thrust gear wheels are secured, and two intermediate pinion units which are set in bearings and engage with the gear wheels and with each other. The gearing is also provided with at least two intermediate shafts, distant rings, and disks with bearing supports for the intermediate shafts. The bottom disk is rigidly secured to the housing. The distant rings are interposed between the disks. The pinion units are formed with coupled pinions of lesser and grater diameters and set in bearings mounted on the intermediate shafts. The disks have openings for free passing of the pinion of lesser diameter in assembling of the reduction gear. Distances between the centers of the shafts of the reduction gear form an equidistant triangle and coupled with the diameter of the dividing circumference of the grater pinion of the pinion unit by a relationship available in the invention description. EFFECT: improved design. 2 dwg
