用于热模锻生产的机械压力机,在其主轴(偏心轴)和传动轴的两端,分别固定着飞轮、传动小齿轮、离合器内套和制动器内套。它们和轴的固定方法大多采用键连接和机械锁紧连接,而西德Hasenclever公司生产的机械压力机系列产品(公称压力1600～12000tf)却一律采用了独特的连接方法一无键连接。无键连接也称液压锁紧技术,适用于任何要求和轴固定配合的零件。现以机械压力机主 Mechanical press for hot forging production, the main shaft (eccentric shaft) and the shaft ends, respectively, the fixed flywheel, drive pinion, clutch inner sleeve and the brake sleeve. They and the shaft are mostly fixed by key and mechanical locking connection, and West Germany Hasenclever company’s series of mechanical presses (nominal pressure 1600 ~ 12000tf) are always using a unique connection method without a key connection. The keyless connection, also known as hydraulic locking technology, is suitable for any part that requires a fixed fit with the shaft. Is the main mechanical press
