Gearbox and construction machine

Abstract

The utility model belongs to the technical field of engineering machinery, disclose gearbox and engineering machinery. The gearbox includes the box, and the output gear, output shaft, first bearing and second bearing of setting in the box, the output gear is set in the output shaft, the both ends of box along the axial direction of output shaft are respectively provided with first opening and second opening, and first bearing and second bearing are supported between output shaft and the inner wall of box, first bearing is close to first opening setting, and second bearing is close to second opening setting, still include output flange and gland, output flange sets up at first opening, and is connected with output shaft, and the gland is sealed in second opening. Through setting first opening and second opening, increase the assembly space of key components such as output gear, first bearing and second bearing, make the assembly and disassembly process more convenient, and can reduce the risk of causing damage to parts in the assembly and disassembly process, improve the maintenance efficiency of gearbox, and save the material cost of box.
