At last conclude and introduce about the future prospects of the fans. Key words: Plane rocker。 transmission ratio。 Worm Gear。 Gear。 sports analysis。 dynamic demo目 錄 摘要i Abstractii 第一章 引言1 電風(fēng)扇發(fā)展現(xiàn)狀和前景展望 1 臺(tái)扇的結(jié)構(gòu)與工作原理1 第二章 電風(fēng)扇搖頭裝置機(jī)構(gòu)的設(shè)計(jì)3 電風(fēng)扇搖頭裝置機(jī)構(gòu)設(shè)計(jì)概述3 電風(fēng)扇搖頭裝置機(jī)構(gòu)設(shè)計(jì)原則3 方案擬定3 Ⅰ (離合式搖頭機(jī)構(gòu))3 Ⅱ (锨撥式搖頭機(jī)構(gòu))4 方案 Ⅲ (平面連桿搖頭機(jī)構(gòu))183
