在水泥生产工艺流程中,球磨机是非常重要的机械设备,该产品的设计工作决定着其质量和经济效益的好坏,强度设计则是设计工作的核心.磨头(或磨尾)用螺栓固联到筒体法兰上,如图1所示,其上固定有中心传动机构的传动轴,或边缘传动装置的大齿轮.由此,在一端磨头的螺栓承受着最大的载荷.在磨头和筒体法兰上,安装有两种同直径的螺栓,其一是铰制螺栓,用来承受筒体重量和电机传至磨头扭矩的共同作用而产生的剪切力;其二是联接螺栓,主要承受轴向载荷.有关铰制螺栓的强度计算在这里就不介绍了.
In the cement production process, ball mill is a very important mechanical equipment, the design of the product determines its quality and economic benefits of good and bad, strength design is the core of the design work. Grinding (or grinding tail) with a bolt Coupled to the cylinder flange, as shown in Figure 1, on which the central drive mechanism is fixed on the drive shaft, or the edge gear of the gear, which ends at one end of the bolt to withstand the maximum load in the mill Head and cylinder flange, the installation of two kinds of bolts with the same diameter, one is the hinge bolt, used to withstand the weight of the cylinder and the motor to the grinding head torque generated by the shear force; the other is Coupling bolts, the main axial load to bear on the strength of the hinge bolts are not introduced here.
