Abstract
The invention relates to a main reducing gear with a walking shaft sealing structure. The main reducing gear comprises a casing and is characterized in that a walking shaft is horizontally distributed in the casing; the two ends of the walking shaft are respectively located by a double-row radial ball bearing and the casing, the walking shaft is sleeved by a walking gear, and the walking gear is fixed to the inner lateral wall of the walking shaft through a sealing gasket; a medium-speed shaft is arranged in the casing, and the middle-speed shaft is sleeved by a medium-speed mesh gear; and large helical-tooth cylindrical gear rings attached to the medium-speed mesh gear are arranged at the two ends of the medium-speed mesh gear, and the large helical-tooth cylindrical gear rings are in mesh transmission with the walking gear. The main reducing gear with the walking shaft sealing structure is simple in structure, saves oil consumption and improves work efficiency. In addition, a loading machine can provide larger driving force in a using process.
