Abstract

The invention discloses a furnace top distributing gear for distributing materials on the top of an iron-fining furnace, belonging to the technical field of mechanical engineering. A rotating motor and a tilting motor are independently driven by a set of differential mechanisms, wherein differential mechanism drive and previous-stage drive adopt all-gear drive, the previous-stage drive of a central sun wheel of the differential mechanism adopts gear drive with common drive ratio, and a furnace pot is tilted by a three-ring speed reducer. The furnace top distributing gear can realize the functions of furnace pot tilting, furnace pot rotation and furnace pot tilting and rotation, has the advantages of compact structure, reliable drive, stable work, high drive efficiency, long service life, little maintaining workload and convenient furnace pot replacement, can be used for blast furnace engineering of various types or other places where loose unpacked materials are delivered.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and discloses a furnace top distributor, in particular a furnace top distributor for ironmaking. Background technique [0002] The ironmaking furnace top distributor is the core equipment of the ironmaking furnace top. At present, the distributors used in China are almost imported foreign equipment, especially large blast furnaces. The distributor introduced in China is vertically installed with a planetary differential mechanism, and the output transmission of the concentric shaft meets the transmission requirements; the planetary differential mechanism, gears and worm wheels are installed vertically, and the lubrication system is complicated; the structure of the concentric output shaft is relatively Complex, and the size of the hollow shaft is large, and the sealing is not easy; in order to meet the large transmission ratio requirements of the tilting chute, the previous stage o...
