桥式起重机起升机构
Hoisting mechanism of bridge crane
桥式起重机的起升机构是通过电机带动制动轮的梅花联轴器与减速机的高速轴相联,制动器固定在减速箱体上,这样制动器和制动轮就不存在因小车架受再变形产生相对位移,从而保证制动器处于良好的工作状态,平衡滑轮组和动滑轮组通过铰轴与小车架相联,可以保证钢丝绳相对平衡滑轮平面的偏角为零,对动滑轮平面的偏角为最小,卷筒组由短轴式钢卷筒和轴承座等零件组成,两端的轴承座固定在小车架上。起升减速器之输出轴通过花键套装联接在卷筒轴上,其输入轴侧底则支撑在小车架上。
The bridge crane hoisting mechanism is high-speed shaft driven by the motor and reducer coupling brake wheel, brake fixed on the gear box, the brake and the brake wheel does not exist because of the small frame by re deformation relative displacement, so as to ensure the brakes in good working condition, balance pulleys and movable pulleys through a hinge shaft and a small frame is connected, can guarantee the relative balance of wire rope pulley plane angle is zero, the plane is the smallest angle of the movable pulley, reel group composed of short axis type steel drum and the bearing seat and other parts, the two ends of the bearing seat is fixed on the trolley frame. The output shaft of the lifting reducer is connected to the drum shaft through a spline set, and the bottom of the input shaft is supported on the small frame.
