Ft1= Fa2 = = = 556 H
Radial kuch
Fr2= Fr1 =Ft2 tga =5560 tg =2001 H
Chervyak vali
l1= daM2=440 mm, =100 mm
xz tekisligi
Rx1= Rx2= = = 278 H
yz tekisligi
-Ry1 l1 + Fr1 – Fa1 = 0
Ry1= =368,6 H
Ry2 l1 + Fr1 – Fa1 = 0
Ry2= = 1632,4 H
Tekshirish:
Ry1+Ry2 –Fr1 = 368,6 +1632,4- 2001= 0
R1= Pr1= = =461,6 H
R2= Pr2= = =523,6H
Endi chervyak vali uchun epyuralarini kuramiz.
