Main transmission device of large excavator lifting mechanism
The invention discloses a main transmission device of a large excavator lifting mechanism. The main transmission device of the large excavator lifting mechanism comprises a lifting drum large gear, afirst planetary gear box and a second planetary gear box, wherein the first planetary gear box and the second planetary gear box are independent of each other, and the lifting drum large gear is connected with a drum shaft; bearing pedestals at the two ends of the drum shaft are independent of a lifting box body and fixed to a lifting mechanism equipment platform; the lifting box body is connectedto the lifting mechanism equipment platform through a hinge structure; the first planetary gear box and the second planetary gear box are symmetrically arranged on the two sides of the lifting box body, and an output small gear shaft of each planetary gear box drives the lifting drum large gear; eccentric parts are arranged in mounting flange mounting holes of the planetary gear boxes and the centers of the planetary gear boxes, and eccentric sleeves are arranged on gear shaft bearings of the output small gear shafts. The device solves the difficulty that a lifting mechanism adjusts contact of gear pairs on the two sides of the lifting drum large gear by adjusting a drum shaft support and meets the design requirement at the same time, solves the problem that a lifting box body is deformedand damaged by bearing the tension of a drum, solves the problem that a drum shaft bearing is damaged, solves the problem that an excavator shed is disassembled when spare parts are replaced, and improves the reliability of an excavator.
本发明公开了一种大型挖掘机提升机构的主传动装置，包括提升卷筒大齿轮、相互独立的第一和第二行星齿轮箱，提升卷筒大齿轮与卷筒轴联接，卷筒轴两端轴承座独立于提升箱体并固定于提升机构设备平台，提升箱体通过铰接结构连接于提升机构设备平台；第一和第二行星齿轮箱对称布置在提升箱体的两侧，行星齿轮箱的输出小齿轴驱动提升卷筒大齿轮；行星齿轮箱的安装法兰安装孔与行星齿轮箱的中心设置有偏心，输出小齿轴的齿轴轴承设置有偏心套。本发明的装置解决了提升机构通过调整卷筒轴支撑来调整提升卷筒大齿轮两边齿轮副接触同时满足设计要求的困难，解决了提升箱体受卷筒拉力变形损坏的问题，解决了卷筒轴轴承损坏的问题，解决了更换备件时拆掉挖掘机机棚的问题，提高了挖掘机的可靠性。
