開封輪邊減速器的速比怎樣計算啊?

    傳動(dong)比是機構(gou)(gou)(gou)中兩(liang)轉(zhuan)動(dong)構(gou)(gou)(gou)件角速(su)度(du)的比值,也(ye)稱速(su)比。構(gou)(gou)(gou)件a和(he)構(gou)(gou)(gou)件b的傳動(dong)比為(wei)i=ωa/ ωb=na/nb,式中ωa和(he) ωb分別為(wei)構(gou)(gou)(gou)件a和(he)b的角速(su)度(du)(弧度(du)/秒);na和(he)nb分別為(wei)構(gou)(gou)(gou)件a和(he)b的轉(zhuan)速(su)(轉(zhuan)/分)。

當式中的(de)(de)角速度為瞬時(shi)值時(shi),則求(qiu)得(de)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)為瞬時(shi)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)。當式中的(de)(de)角速度為平均(jun)(jun)值時(shi),則求(qiu)得(de)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)為平均(jun)(jun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)。理論上對(dui)(dui)于(yu)大多(duo)數漸(jian)開線齒(chi)廓正確(que)的(de)(de)齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),瞬時(shi)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)是(shi)不變的(de)(de);對(dui)(dui)于(yu)鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),瞬時(shi)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)是(shi)變化的(de)(de)。對(dui)(dui)于(yu)嚙合(he)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)可用(yong)(yong)a和(he)b輪(lun)的(de)(de)齒(chi)數Za和(he)Zb表示(shi)(shi),i=Zb/Za;對(dui)(dui)于(yu)摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)(bi)(bi)可用(yong)(yong)a和(he)b輪(lun)的(de)(de)直(zhi)徑(jing)Da和(he)Db表示(shi)(shi),i=Db/Da。

 

計算方法:

傳動比=使用扭(niu)矩(ju)÷9550÷電機功率×電機功率輸入轉數(shu)(shu)÷使用系數(shu)(shu)

傳動(dong)(dong)(dong)比=主動(dong)(dong)(dong)輪轉速(su)除(chu)以(yi)從動(dong)(dong)(dong)輪轉速(su)的值=它們分度圓直徑比值的倒數。即:i=n1/n2=D2/D1

i=n1/n2=z2/z1(齒輪的)

對于多級(ji)齒輪(lun)傳(chuan)動(dong)(dong):1.每兩軸之間的傳(chuan)動(dong)(dong)比按照上面的公式計算。 2.從第一軸到第n軸的總傳(chuan)動(dong)(dong)比等于各級(ji)傳(chuan)動(dong)(dong)比之積
