安装注意事项 Warning
●摩擦片及衔铁表面不得有油污，必须保持清洁；
Friction disc and armature surface should be kept clean and free of grease.
●安装时必须保证气隙“δ”；
When fixing, the airgap "δ" should be kept to the specified value.
●齿轮套不得有轴向窜动。
The gear hub are not allowed to move along axially.
●安装后必须旋出空心螺栓锁紧在电机后端盖或法兰盘上。
Turn the hollow bolt so that it is fixed on the bake cover or the flange plate.
