Mashinasozlik turli sohalarni taraqqiy etishi uchun zarur bo‘lgan texnikaviy baza yaratadi

Podshipnikni mustaxkamlikka xisobi

F_t2= F_a1 = = = 5560 H

F_t1= F_a2 = = = 556 H

Radial kuch

F_r2= F_r1 =F_t2 tga =5560 tg =2001 H

Chervyak vali

l₁= d_aM2=440 mm, =100 mm

xz tekisligi


R_x1= R_x2= = = 278 H


yz tekisligi

-R_y1 l₁ + F_r1 – F_a1 = 0

R_y1= =368,6 H

R_y2 l₁ + F_r1 – F_a1 = 0

R_y2= = 1632,4 H

Tekshirish:

R_y1+R_y2 –F_r1 = 368,6 +1632,4- 2001= 0

R₁= P_r1= = =461,6 H

R₂= P_r2= = =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=eP_r1 = 0.36 461.6 = 166 H

S₂=eP_r2 = 0.36 523.6 = 188 H
