A compact drum coupler for hoisting equipment and a connecting mode thereof comprise a speed reducer (1), a drum connecting flange (3), a drum body (4) and a drum coupler (2) connected between a spline shaft end of the speed reducer and the drum connecting flange (3). The device is characterized in that the end, connected with the speed reducer spline shaft, of the winding drum coupler (2) penetrates through a central shaft hole of the speed reducer spline shaft end flange (6), extends to the inner side of the speed reducer spline shaft end flange, makes contact with a speed reducer spline shaft positioning shoulder through a positioning check ring (8) and is axially positioned through a spline shaft end sealing plate (7). According to the lifting platform, the distance between the speed reducer and the winding drum is greatly reduced, and compact design of the lifting platform is achieved; the axial positioning of the drum coupler is ensured through the positioning check ring and the spline shaft end sealing plate; by arranging the lubricating oil channel in the drum coupler, the meshing state of the internal and external splines can be improved, and the service life of the internal and external splines is effectively prolonged.
一种起重设备用紧凑型卷筒联轴器及其连接方式,包括减速机(1)、卷筒连接法兰(3)、卷筒筒体(4)、连接在减速机花键轴端与卷筒连接法兰(3)之间的卷筒联轴器(2),其特征在于:所述卷筒联轴器(2)与减速机花键轴连接端穿过减速机花键轴端法兰(6)中心轴孔延伸至减速机花键轴端法兰内侧,通过定位挡圈(8)与减速机花键轴定位台肩相接触,并通过花键轴端密封板(7)实现轴向定位。本发明大幅缩减了减速机和卷筒之间的间距,实现起重平台的紧凑设计;通过定位挡圈和花键轴端密封板保证卷筒联轴器的轴向定位;通过在卷筒联轴器内部设置润滑油道,能够改善内外花键的啮合状态,有效提升内外花键的使用寿命。
