匈牙利产的 VF 221立式铣床的进给系统,有 18种工作进给速度和一条单独的快速移动传动链,由一个 1.8 kW的马达驱动。工作进给和快速移动传动链上各有一只结构特殊的单向超越离合器。图1为快速移动传动链上的离合器的结构(简称“离快”);工作进给传动链上的离合器亦类似(简称“
The feed system of the Hungarian VF 221 vertical milling machine with 18 working feed rates and a separate fast moving drive chain is driven by a 1.8 kW motor. Working feed and fast moving drive chain each have a special one-way overrunning clutch. Figure 1 shows the structure of the clutch on the fast-moving drive chain (referred to as “quick-release”); the clutch on the working feed drive chain is also similar ("
