The invention discloses a superlift winch speed reducer matched with a crane, which belongs to the technical field of boom type crane parts and comprises a winding drum, three-stage planetary gear transmission is arranged in a drum cavity of the winding drum, an output stage adopts a transmission structure with larger transmission torque, and an input stage and a middle stage adopt transmission structures with smaller transmission torque. Through the layout design, the input stage, the middle stage and the rear supporting shaft can share part of axial installation space, the axial space requirement is further reduced, a large speed ratio can be obtained through a small-displacement motor in the limited assembling space of a crane boom, and the super-lifting function requirement of a crane is met.
本发明公开了一种配用于起重机的超起卷扬减速机,属于臂架型起重机部件技术领域,包括卷筒,在所述卷筒的筒腔内布局三级行星齿轮传动,其中输出级用传递扭矩较大的传动结构,输入级和中间级用传递扭矩较小的传动结构,通过布局设计使得输入级,中间级与后支撑轴可以共享部分轴向安装空间,进一步缩小轴向的空间需求,能在起重机臂架有限的装配空间内以小排量马达配出较大的速比,满足起重机的超起功能需求。
