Metallurgy gearbox structure

The utility model discloses a metallurgical gear box structure and relates to a metallurgical gear box structure designed to transmit load by using the load shunt and confluence technology and adopting a herringbone gear structure; the structure mainly comprises a box body, a blank cap and two gear transmission mechanisms, wherein the gear transmission mechanisms operate independently; each gear transmission mechanism comprises two input shafts and an output shaft that are mutually engaged by taking a herringbone gear as a transmission gear and used for transmitting power; each input shaft is provided with an independently-driven motor; the herringbone gears in the two gear transmission mechanisms are arranged in a staggered way; the improved metallurgical gear box has the advantages of small volume, compact structure, large transmission power, high carrying capacity and shock resistance, less influence from the outside, long service life, light weight, high rigidity, low noise and the like; therefore, the application scope is very wide; and the metallurgical gear box structure is especially suitable for the occasions that high-power heavy-duty transmission is performed, a motor is required to be braked or to operate forward and reversely, very large impact or overload is required to be borne in the working process, etc.
