摘　　要：介绍了一种集成式高精度流量调节机构,针对固体冲压发动机的特殊空间和精度要求,进行了小型化、轻质化设计。将调节机构与控制驱动器进行集成式设计,有效利用空间尺寸;对末级直齿轮进行扇形设计,减小调节机构体积;采用特殊的花键连接和双齿轮消隙结构等连接方式,有效控制调节机构的传动间隙,提高调节机构的传动精度。通过试验验证,该调节机构方案设计合理、可行,并具有较高的传动精度和快速性,可以满足固体冲压发动机特殊空间和高精度的要求。An integrated and high precision flow regulation mechanism is introduced.For the special space and high precisionrequirement of the solid ramjet,a miniaturization and light-weight flow regulation mechanism is designed.The electronic controldriver are integrated into the regulation mechanism,effectively accommodating the installed space.To reduce the volume,the finalstraight gear is designed to be fan-shaped.By using the special spline connection and double-gear eliminating backlash structure,transmission clearances are well controlled and the transmission accuracy improved.The experimental result shows that the design isreasonable and feasible,having high transmission accuracy and speed and meeting the requirements.
