二、傳動(dòng)原理與結(jié)構(gòu)DRIVING PRINCIPLE & CONSTRUCTION
 

行星擺線針輪減速機(jī)的傳動(dòng)原理如圖1如示:

輸入軸1和轉(zhuǎn)臂3一起繞中心Ob順時(shí)針方向回轉(zhuǎn)時(shí)，擺線輪2即隨轉(zhuǎn)臂一道繞中心Ob公轉(zhuǎn)。由于固定在針齒殼5上的針齒的反作用使擺線輪繞其本身中心OC逆時(shí)針方向自轉(zhuǎn)，并通過銷套銷軸將其自轉(zhuǎn)等速傳遞給輸出軸4，故輸出軸就得到了與輸入軸相反轉(zhuǎn)向的運(yùn)動(dòng)(輸入軸轉(zhuǎn)動(dòng)一周，輸出軸擺線輪轉(zhuǎn)動(dòng)-I/EC周)，其減速比為:
The Driving Principle of Planet cycloidal pin gear reducer is showed in the diagram 1.When input shaft 1 and rotating arm 3 are rotating around the OB Axis in chocdwise the cycloidal gear 2 will rotate aroundthe Sxis OB togethert the rotating arm. The cycloidal gear wll self-rotating around OC in countclockwise due to the counteractiorof pin gear fixing in the pin gear shell 5, meanwhile, the self-rotation speed will be passed to output shaf 4 through pin shaft.as result, the output obtain the contrary movement against input shat. (When input shaf rotate one cycle, the output cycloidalgrat will rotate -1/EC cycle.), its velocity-reducing ratio is:
i=(Ec-Eb)/Ec=-I/Ec 其中:EC-Eb)=-1
i=(Ec-Eb)/Ec=-I/Ec among it:Ec-Eb=-1
Ec--擺線輪齒數(shù)  Eb--針齒齒數(shù)

Ec - Tooth No.If cycloidal gear, Eb-pin gear No

由上式可知當(dāng)輸入軸轉(zhuǎn)Ec轉(zhuǎn)時(shí)輸出軸則反向轉(zhuǎn)1轉(zhuǎn)
According to above formula, shen input shaft rotate Ec cycles, the output shaft wil rotate one cycle in counterdirection.

4、故障少，壽命長:本機(jī)主要轉(zhuǎn)動(dòng)嚙合件采用軸承鋼制造，因此機(jī)械性能好，耐磨性好，再加采用滾動(dòng)摩擦，故使之

故障少，壽命長。

5、運(yùn)轉(zhuǎn)可靠平穩(wěn)，本機(jī)傳動(dòng)過程中為多齒嚙合，所以使之運(yùn)轉(zhuǎn)平穩(wěn)可靠，噪聲小。

6、拆裝方便，容易維修:由于結(jié)構(gòu)設(shè)計(jì)合理拆裝簡(jiǎn)單便于維修。

7、本機(jī)還具有過載能力強(qiáng)，耐沖擊、慣性力矩小、適用于起動(dòng)頻繁和正反轉(zhuǎn)的特點(diǎn)。
2.High Driving efficiency: the driving effciency can reach above 90% due to adopting rolling engagement in falling-in part
3. Small volume, light weight: this machine has compacted structure,small volume and light weight because of adoptingthe priciple of planef driving so that the input shaft and output shaft in the same axis,moreover,they will integrated witrthe motor.

4, Few troubles,long life: this machine has good resistance to abrasion because the main driving engaging parts

are made of bearing steel and applying rolling friction.

5. Stable Running: For most driving procedure, we adopt multi-teeth falling-in. so the running will be stable and

little noise.

6. Convenient dismounting, easy maintanance: Due to reasonable structure and design.
7. This machine also are of the characteristics such as strong overloading ability, ability,anti-compact, Samll inertiamoment, which are suitable for frequently start and double-side rotation.
