Podshipnikni mustaxkamlikka xisobi

Ft2= Fa1 = = = 5560 H


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.


Ishlash soati

Uk buyicha radial reaksion podshipnikda kuchlanish


Podshipnik №7204 ye=0,36 S=21,0 kN
Podshipnik №7212 ye=0,35 S=78 kN

S1=ePr1 = 0.36 461.6 = 166 H


S2=ePr2 = 0.36 523.6 = 188 H

Xisobiy ishlash soati

Lh= = = 18698 soat.
