I. Elektrodvigatel tanlash va yuritmaning kinematik xisobi

2. Tishlarning faol sirtlari kontakt mustahkamligi shartidan o’qlararo masofani hisoblaymiz.
a_w=K_a ( +1)
a_w= 43 (3.2+1)
a_w=159,6 mm
K_a:=43 i:=i_red i=4,46 :=1.05 0.36 T₃=391,55 N m
GOST 2185-66 Standarti bo’yicha a_w:=160 mm deb qabul qilamiz.


3.Normalmodulnianiqlaymiz.
m_n:=(0.01 0.02) a_w m_n:=(0.01 0.02) 200 m_n:=(1,6 3,2)
GOST 9563-60 Standarti bo’yicha m_n:=2 mm deb qabul qilamiz.


4.Shesternya va tishli g’ildirak sonini aniqlaymiz.

:= ; .
Shunda,

Qiya tishli va shervon tishli uzatmalar uchun umumiy tishlar sonini toppish formulasi:
z_w= = = =156.8
cos tishning qiyshiqlik burchagi =10
5.Silindrik tishli g’ildirakning konstruktiv o’lchamlarini aniqlash
1) Tishning balandligi h=2.25*m_n=2.25*2=4.5
2) Tishning uchini balandligi h_a=m_n=2
3) Tish tubining balandligi h_f=1.25*m_n=1.25*2=2.5
4) Bo’luvchi aylana diametri d=m_n*z₂=2*128=256
5) Tish uchi aylanasining diametri d_a=m_n(z₂+2)=2*(128+2)=260
6) Tish tubi aylanasining diametri d_s=m_n(z₂-2.5)=2*(128-2.5)=251
7) Obod qalinligi va diametri ₀=(2.5…4)*m_{n 0}=5
2.5*2=5 d_ob=d_a-8.5*m_n=260-(8.5*2)=243
4*2=8
8) Obod tub qismi aylanasining diametri
D₀= d_a-2*(h+ ₀)=260-2(4.5+5)=2451
9) Tish uzunligi b=(6…8)*m_n b=12
6*2=12
8*2=16
10) Disk qalinligi c=(0.2…0.3)*b c=2.4
0.2*12=2.4
0.3*12=3.6
11) Val uchun tishik diametri d_b=0.2*d_a=0.2*260=52
12) Stupitsa:diametri va uzinligi d_cm=1.6*d_b=1.6*52=83.2
l_cm=1.1*b=1.1*12=17.6
13) Diskni yengillashtiruvchi teshiklar markazlarining diametri
D₁=0.5*(D₀+d_cm)=0.5*(2451+83.2)=1267.1
