扇齿发动机换向结构设计

Design of the sector-gear-motor's structure for director changing

扇齿发动机用齿轮齿条代替了传统的曲柄连杆机构,发动机的机械效率有望得到较大的提高,是我校申请的专利(ZL021336601)。对该发动机的工作原理进行了简要介绍,设计了槽和轮以保证发动机换向时能够较好地过渡。

The crank-rocker mechanism is instead by the sector gear and rack mechanism in the sector gear motor, so the mechanical efficiency could be much better（ China parent ZID21336601 ）. The principle of the motor was introduced. And a structure was designed for the motor＇s director changing to control the motion of the sector gear when the sector gear and the rack were completely disengaged.
