双齿轮渐近同步驱动系统设计

为解决轨道拖拽、龙门设备、自动升降等大负载、长跨度设备的驱动功率不足、设备刚度差、结构尺寸较大等问题,提出了一种基于电气伺服驱动技术的双齿轮渐近同步驱动解决方案。该渐近同步驱动方案采用在一个主动齿轮驱动负载齿轮传动的基础上,逐渐添加其他主动齿轮以增大驱动功率的双齿轮同步驱动系统,实现了电气伺服同步驱动功能;采用台达数控系统,实现了双齿轮高精度同步控制。研究结果表明,该驱动方案具有同步可靠性高、控制方便、启停同步一致性强等特点。

Design for double gear of gradual synchronous driving system

In order to solve the problem of insufficient of driving power,poor stiffness and large-dimension structure of heavy load and long span frame device, such as orbital towing equipment, gantry device, raised and lowered automatically equipment, a double gear of gradual synchronous driving system based on electrical servo drive technology was introduced. A driving gear was adopted first to drive the load of a gear in the gradual synchronous driving system and then the other driving gear was adopted. Delta＇s CNC system was adopted to realize the double gear synchronous control system with high precision. The results indicate that, the system is featured by highly reliability, convenient control, start and stop with high synchronous precision.
