Numerically controlled gear teeth generator - has separate drive for tool and workpiece spindles with speed-setting planetary gearing

摘要

The generation of spur, bevel or other gears is ensured by a numerically controlled hobber drive of tool spindle workpiece spindle rotation. The same drive controls the linear advance of the tool spindle while the corresp. support of the hobber can turn around its axis. adjustment of the speed of the workpiece spindle is achieved with planetary gearing featuring a separate drive ensuring simplified handling of the machine. The numerical control enhances the accuracy of gears as well as improves machining efficiency.
