The invention discloses a special speed-reducing winding drum for a crane, which comprises a winding drum body, a driving motor and a speed-reducing gear mechanism, the speed-reducing gear mechanism comprises a front-section planetary gear set and a rear-end reversing gear set, and the planetary gear set and the reversing gear set are respectively combined with a horizontal shaft bevel gear in a same closed-loop differential bevel gear train. Under the action of the revolution planetary gear train and the reversing planetary gear train, the rotating directions of the bevel gears are opposite, and the rotating speeds are different, so that the differential speed of the bevel gear train is realized. The transmission mode is a novel differential transmission speed reduction technology, the speed reducer can be directly installed in the winding drum, the installation space can be saved, due to the large transmission ratio of differential transmission, the mass of the speed reducer can be reduced, the cost is saved, and more possibilities are provided for reduction design of the crane.
本发明公开了一种起重机专用减速卷筒,包括卷筒体,驱动电机,减速齿轮机构,减速器齿轮机构包括前段行星齿轮组和后端换向齿轮组,行星齿轮组和换向齿轮组分别同一闭环差速锥齿轮系中的水平轴锥齿轮结合,经过公转行星轮系和换向行星轮系的作用实现了锥齿轮转向相反且转速不同,如此便实现了锥齿轮系的差速。上述传动方式为一种新颖的差速传动减速技术,减速器可直接安装于卷筒内部,不仅可节约安装空间,且由于差速传动较大的传动比,可降低减速器的质量并节约成本,为起重机的减量化设计提供了更多的可能。
