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=190.6 mm
K_a:=43 i:=i_red i=3.2 :=1.15 0.25 T₃=477.70 N m
GOST 2185-66 Standarti bo’yicha a_w:=200 mm deb qabul qilamiz.


3.Normalmodulnianiqlaymiz.
m_n:=(0.01 0.02) a_w m_n:=(0.01 0.02) 200 m_n:=(2 4)
GOST 9563-60 Standarti bo’yicha m_n:=2.5 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*2.5=5.625
2) Tishning uchini balandligi h_a=m_n=2.5
3) Tish tubining balandligi h_f=1.25*m_n=1.25*2.5=3.125
4) Bo’luvchi aylana diametri d=m_n*z₂=2.5*122=305
5) Tish uchi aylanasining diametri d_a=m_n(z₂+2)=2.5*(122+2)=310
6) Tish tubi aylanasining diametri d_s=m_n(z₂-2.5)=2.5*(122-2.5)=298.75
7) Obod qalinligi va diametri ₀=(2.5…4)*m_{n 0}=8
2.5*2.5=6.25 d_ob=d_a-8.5*m_n=310-(8.5*2.5)=288.75
4*2.5=10
8) Obod tub qismi aylanasining diametri
D₀= d_a-2*(h+ ₀)=310-2(5.6+8)=4188.8
9) Tish uzunligi b=(6…8)*m_n b=16
6*2.5=15
8*2.5=20
10) Disk qalinligi c=(0.2…0.3)*b c=4.2
0.2*16=3.2
0.3*16=4.8
11) Val uchun tishik diametri d_b=0.2*d_a=0.2*310=62
12) Stupitsa:diametri va uzinligi d_cm=1.6*d_b=1.6*62=99.2
l_cm=1.1*b=1.1*16=17.6
13) Diskni yengillashtiruvchi teshiklar markazlarining diametri
D₁=0.5*(D₀+d_cm)=0.5*(4188.8+99.2)=2144
