目前工厂使用的锻压、剪切设备,大部分采用曲柄或偏心轮连杆机构(如冲床、前床等)。曲柄或偏心轮连杆机构通过拐点时所需能量是由设备中的飞轮(一般为大齿轮或大皮带轮)供给的。但当飞轮泄放能量时,一部分供给曲栖或偏心轮连杆机构通过拐点;而另一部分能量将引起没备产生振动等。为消除有害部分能量,在其相对位置上安装一对磨擦轮(箍环、箍轮,见图21)。箍轮通过踺与传动轴一起运动,此种结构一般用于冲压力60T以下冲床及剪料厚度3mm、长度1.5M以下的剪床中。但它有下述毛病:一般箍环的材质为铸铁(或钢),而箍轮材质为钢,两者的磨擦系数较小,吸收能量的潜力不大。两者
At present the factory used forging, cutting equipment, most of the crank or eccentric linkages (such as punch, bed, etc.). The energy required to pass the crank or eccentric link mechanism through the inflection point is supplied by the flywheel (typically a large gear or a large pulley) in the device. However, when the flywheel releases the energy, a part of the supply of the crank or eccentric link mechanism passes the inflection point; and the other part of the energy will cause the equipment to generate vibration. To eliminate harmful part of the energy, a pair of friction wheels (hoops, hoops, see Figure 21) are mounted at their relative positions. Hoop wheel 传 with the drive shaft through the movement, this structure is generally used for punching force 60T the following punching and trimming thickness 3mm, length of 1.5M in the following shear. However, it has the following defects: The material of a general hoop ring is made of cast iron (or steel), while the material of the hoop wheel is steel. The friction coefficient of the two is small and the potential for energy absorption is small. Both
