   Loyihalanayotgan teplovoz yuk tortuvchi reduktori parametrlarining hisob-kitobi
   

Elektrodvigatelning yuk tortuvchi validagi aylanish jarayoni tishli silindrik reduktor orqali g‘ildiraklar juftligiga uzatiladi.
G‘ildirak – motor blokining yuk tortish xususiyatiga ta’sir ko‘rsatuvchi asosiy parametr ushbu reduktorning tishli uzatkichlari imkoniyatlariga bog‘liq.
G‘ildirak – motor blokining uzoq muddatli ish rejimida aniqlanadigan uzatkichlar soni μ g‘ildirak gardishidagi aylanish jarayonining yuk tortuvchi elektrodvigatel validagi jarayonga bo‘lgan munosabatni anglatadi.
μ =M_k/M_D∞ =F_D∞D_K/2M_D∞ (5)
µ_p^ayl= F_DaylD_K/2 M_D^ayl
µ_p^ayl= 45,67*1,05/2*8,3=2,89

µ_p^pr = F_DprD_K/2 M_D^pr
µ_p^pr = 46,46*1,05/2*8,42=2,89
F_D∞ – g‘ildirak – motor blokining uzoq muddatli yuk tortish kuchi, kN;
M_D∞ – yuk tortuvchi elektrodvigatelning uzoq muddatli aylanish jarayoni, kN ^. m;
D_K – g‘ildirak diametri, m.
F_D∞ va M_D∞ kattaliklari quyidagi tenglamalar yordamida aniqlanishi mumkin.
F_D∞ = 3,6P_D∞ /V_p; (6)


F_Dayl = 3,6 P_D^ayl /V_p
F_Dayl =3,6*307/24,2=45,67


F_Dpr = 3,6 P_D^pr7 /V_p
F_Dpr =3,6*312,3/24,2=46,46


M_D∞ = 9,5P_D∞ / n_D∞ (7)


M_D^ayl = 9,5 P_D^ayl/ n_D∞
M_D^ayl =9,5*307/352,3=8,3


M_D^pr = 9,5 P_D^pr / n_D∞
M_D^pr =9,5*312,3/352,3=8,42


n_D∞ =n_dmaxV_p /V_kon (8)
n_D∞ =1456*24,2/100=352,3
Bunda, P_D∞ – bitta yuk tortuvchi elektrodvigatelning quvvati, kVt;
V_p – teplovozning mo‘ljallangan harakat tezligi, km/s;
n_D∞ – yuk tortuvchi elektrodvigatel yakori aylanishining uzoq muddatli chastotasi, min^-1
n_dmax – yuk tortuvchi elektrodvigatel yakorining maksimal yo‘l qo‘yilishi mumkin bo‘lgan aylanish chastotasi. Bunda 2200/2300 min^-1ga teng bo‘lgan hisob-kitob e’tiborga olinadi.
(6, 7, 8) tenglamalarni formulaga (5) qo‘ygan holda quyidagi ko‘rsatkichni olamiz:
μ_pr =0,19n_dmax D_k/V_kon
µ_p =0,19*1456*1,05/100=2,9

YUqorida keltirilgan formula yordamida aniqlangan µ_p uzatuvchi son, teplovozning uzoq muddatli harakatiga mos keladigan, uzoq muddatli ish rejimida F_D∞ M_D∞ ko‘rsatkichlarini aniqlab berishdan tashqari, yuk tortuvchi elektrodvigatelning mustahkamlik shartini, yakorning konstruksion tezlikda yo‘l qo‘yilish mumkin bo‘lgan ko‘rsatkichdan n_dmax oshmaydigan aylanish chastotasini ta’minlaydi.

G‘ildiraklar juftligi va yuk tortuvchi elektrodvigatel yakorining o‘qi oralaridagi farqni ko‘rsatuvchi uzatuvchi sonning yakuniy qiymati, qabul qilingan A sentral uzunligini hisobga olgan holda qo‘yiladi.
A=(z₁+z₂)m/2;
A – sentralning uzunligi, mm;
m – tishsimon tishlashish (ilinish) moduli;
z₁ va z₂ harakatga keltiruvchi va harakatdagi shesternalar tishlarining soni.
Doiraning eng katta diametrining shesterna tishlariga nisbatidan iborat bo‘lgan, yuk tortuvchi teplovoz uzatkichlari uchun tishsimon tishlashish (ilinish) moduli m, 10ga teng deb olinadi.
TEP60, TEP70 va TEP 75 teplovozlari uchun sentral uzunligi 520mm.ga boshqa seriyadagi teplovozlar uchun 468,8mm.ga teng deb olinadi.
Harakatga keltiruvchi va unga ergashuvchi (ikkilamchi) shesternalar tishlarining soni z₁+z₂ quyidagi ikkita tenglamani birgalikda echish yo‘li bilan aniqlanadi.
