为了满足电机换向器铣槽的需要,我厂设计制造了一台换向器自动铣槽专用设备.按照工艺要求,设备铣槽时铣头拖板应慢速进刀,当整条槽铣削完毕,铣头拖板应快速退刀返回。如为简化设备结构,采用等速进、退刀,则必然影响专用设备的效率;如采用电气变速,则会增加电气控制系统的复杂系数。为此我们设计制造了一套独特的机械变速结构。它由电机轴。传动盘、输出轴和两对齿轮组成.由图可知:在传动盘上有一销孔,沿C、D两面向相反方向开成斜槽形式(?)传动盘还有键槽与电机轴联结,见附图。齿轮Z_(?)与Z_(?)上各有一滚销。当交流电机正转时,齿轮Z_(?)的滚销沿C面插入传动盘带动齿轮Z_1及Z_(?)转动,输出 In order to meet the needs of motor commutator milling slot, I design and manufacture a commutator automatic milling slot for equipment. According to process requirements, the milling slot Milling machine should be slow feed, when the entire groove milling Finished, milling head carriage should be quickly retracted back. Such as to simplify the structure of the device, the use of equal speed, retraction, it will inevitably affect the efficiency of special equipment; such as the use of electrical variable speed, will increase the complexity of the electrical control system coefficient. To this end, we designed and manufactured a unique set of mechanical transmission structure. It consists of motor shaft. Drive shaft, output shaft and two pairs of gears.Figure shows: There is a pin hole in the drive plate, along the C, D both sides open in the opposite direction into a chute (?) Drive plate also has a keyway and motor shaft coupling, see Figure. Gear Z_ (?) And Z_ (?) On each have a roll pin. When the AC motor is rotating forward, the pin of the gear Z_ (?) Is inserted into the drive disk to drive the gear Z_1 and Z_ (?) Along the C surface, and the output
