Abstract
The invention discloses a main drive gear box. An upper box, an upper middle box, a lower middle box and a lower box are sequentially located through locating pins and fastened through bolts from top to bottom to connect into a gear box body. A lower input gear shaft is supported on the lower box through bearings and is sealed between the lower middle box and the lower box respectively through an end cover and an unclosed cover at the two ends of the lower input gear shaft. A front tooth portion and a rear tooth portion are arranged on the lower input gear shaft. A middle left output gear shaft and a middle right output gear shaft are supported on the lower middle box through bearings and are sealed between the lower middle box and the upper middle box through an end cover and an unclosed cover at the two ends of the middle left output gear shaft and an end cover and an unclosed cover at the two ends of the middle right output gear shaft respectively. The tooth portion of the middle left output gear shaft and the tooth portion of the middle right output gear shaft are meshed with the front tooth portion and the rear tooth portion of the lower input gear shaft respectively. An upper left output gear shaft and an upper right output gear shaft are supported on the upper middle box through bearings and are sealed between the upper middle box and the upper box through an end cover and an unclosed cover at the two ends of the upper left output gear shaft and an end cover and an unclosed cover at the two ends of the upper right output gear shaft respectively. The tooth portion of the upper left output gear shaft and the tooth portion of the upper right output gear shaft are meshed with the tooth portion of the middle right output gear shaft and the tooth portion of the middle left output gear shaft.
