18、而使另一個(gè)元件固定不動(dòng)，或使其運(yùn)動(dòng)受一定的約束（即該元件的轉(zhuǎn)速為某定值），則機(jī)構(gòu)只有一個(gè)自由度，整個(gè)輪系以一定的傳動(dòng)比傳遞動(dòng)力.下面分別討論三種情況。</p><p>　　1、齒圈固定，太陽輪為主動(dòng)件且順時(shí)針轉(zhuǎn)動(dòng)，而行星架則為被動(dòng)件。太陽輪順時(shí)針轉(zhuǎn)動(dòng)時(shí)，太陽輪輪齒必給行星輪齒A一個(gè)推力F1，則行星輪應(yīng)為逆時(shí)針轉(zhuǎn)動(dòng)，但由于齒圈固定，所以齒圈輪齒必給行星輪齒B一個(gè)反作用力F2,行星輪在F1和 F2合力作用下必繞太陽輪

19、順時(shí)針旋轉(zhuǎn)，結(jié)果行星輪不僅存在逆時(shí)針自轉(zhuǎn)，并且在行星架的帶動(dòng)下，繞太陽輪中心軸線順時(shí)針公轉(zhuǎn)。在這種狀態(tài)下，就出現(xiàn)了行星齒輪機(jī)構(gòu)作用的傳動(dòng)方式，而且被動(dòng)件行星架的旋轉(zhuǎn)方向與主動(dòng)件同方向。在這里，太陽輪是主動(dòng)件而且是小齒輪，被動(dòng)件行星架沒有具體齒數(shù)的傳動(dòng)關(guān)系，因此定義行星架的當(dāng)量齒數(shù)等于太陽輪和齒圈齒數(shù)之和。這樣，太陽輪帶動(dòng)行星架轉(zhuǎn)動(dòng)仍屬于小齒輪帶動(dòng)最大的齒輪，是一種減速運(yùn)動(dòng)且有最大的傳動(dòng)比。</p><p>　　2

20、、太陽輪固定，行星架為主動(dòng)件且順時(shí)針轉(zhuǎn)動(dòng)，齒圈為被動(dòng)件。當(dāng)行星架順時(shí)轉(zhuǎn)動(dòng)時(shí)，勢必造成行星輪的順時(shí)針轉(zhuǎn)動(dòng)，但因太陽輪制動(dòng)，太陽輪齒給行星輪齒 B齒一個(gè)反作用力F1,行星輪在F1的作用下順時(shí)針旋轉(zhuǎn)，其輪齒給齒圈輪齒A一個(gè)F2的推力，齒圈在F2的作用下順時(shí)針旋轉(zhuǎn)。在這里，主動(dòng)件行星架的旋轉(zhuǎn)方向和被</p><p>　　動(dòng)件齒圈相同。由于行星架是一個(gè)當(dāng)量齒數(shù)最大齒輪，因此被動(dòng)的齒圈以增速的方式輸出，兩者間傳動(dòng)比小于1。因
