The planetary mechanism safety brake comprises a winding drum shaft, a locking nut, an electric brake, a planetary mechanism and a machine shell, one end of the machine shell is fixedly connected with the winding drum shaft through a bolt, the outer side of the machine shell is fixedly connected with a fixed winding drum support through a bolt, and the other end of the machine shell is fixedly provided with the electric brake through a long bolt; a connecting shaft connected with a drum shaft is rotationally connected into the machine shell, a sun wheel shaft is arranged at one end of the connecting shaft, a planetary mechanism is connected to the sun wheel shaft and comprises a center wheel, a planet wheel, a sun wheel and a gear ring, a locking nut located at one end of the planetary mechanism is arranged in the machine shell, and a friction plate is installed on the locking nut and installed on the sun wheel. According to the planetary mechanism safety brake, the structure can be installed on drum shafts at the tail ends of various lifting and winding drums, the occupied space is small, the braking torque is balanced, and the situation that the drums tilt and violently vibrate due to the fact that braking force is not uniform on the four sides of the drums is avoided.
本发明公开了一种行星机构安全制动器,包括卷筒轴、锁止螺母、电动制动器、行星机构和机壳,机壳的一端通过螺栓固定连接有卷筒轴,机壳的外侧通过螺栓固定连接有固定卷筒支架,机壳的另一端通过长螺栓固定安装有电动制动器,机壳内部转动连接有与卷筒轴连接的连接轴,连接轴的一端设有太阳轮轴,太阳轮轴上连接有行星机构,行星机构包括中心轮、行星轮、太阳轮和齿圈,机壳内部设有位于行星机构一端的锁止螺母,锁止螺母上安装有摩擦片,并安装在太阳轮上,本发明一种行星机构安全制动器,此结构可以安装到各类起升及卷扬滚筒末端的卷筒轴上,占用空间小而且制动扭矩均衡,不会因制动力在滚筒四边不均导致滚筒翘起,及剧烈震动。
