3. Asosiy kinematik parametrlarni aniqlash
2B56 – Radial parmalash dasgoxi asosida tezliklar qutisini loyixalash.
1. SHipindelning eng kichik aylanishlar soni – n_min=105 ayl/daq
2. SHipindelning eng katta aylanishlar soni – n_max=1600 ayl/daq
3. Tezliklar soni va formulasi – Z=24=2х4х3
4. Eng kata ishlov berish o‘ lchamlari – D = 36 mm
5. Ishlov beriladigon material - CЧ21, HB = 220
3.1 Dastgoh shpindelining n dan n_max gacha bo’lgan oraliqdagi aylanish chastotasi qatori hisoblanadi.
n_min=n₁;
n₂=n₁ ;
n₃=n₂ =n₁ =n₁ ²;
n₃=n₂ =n₁ =n₁ ²………………………….
n_max=n_z=n₁ ^z-1}
ketma ketlik bajarilishi kerak bo’lib u geometrik progressiyani tashkil qiladi.
Bu yerda geometrik progressiya maxraji bo’lib
ga teng.
Z=16=2*4*2 ekanligidan
Standardga yaqin qiymat =1.12 deb qabul qilamiz
Standart qiymat qabul qilamiz.
n`1 = 750 ayl/min
n_min= 105 ayl/min
n₂=105*1.12= 117 ayl/min
n₃= 117 *1.12= 131 ayl/min
n₄= 131 *1.12= 147 ayl/min
n₅= 147 *1.12= 165 ayl/min
n₆= 165 *1.12= 185 ayl/min
n₇= 185 * 1.12= 207 ayl/min
n₈= 207 *1.12 = 232 ayl/min
n₉= 232 *1.12= 259 ayl/min
n₁₀= 259 *1.12= 291 ayl/min
n₁₁= 291 *1.12= 326 ayl/min
n₁₂= 326 * 1.12= 365 ayl/min
n₁₃= 365 *1.12= 409 ayl/min
n₁₄= 409 *1.12= 458 ayl/min
n₁₅= 458 *1.12= 513 ayl/min
n₁₆= 513 *1.12= 574 ayl/min
n₁₇= 574 *1.12 = 643 ayl/min
n₁₈= 643 *1.12= 720 ayl/min
n₁₉= 720 * 1.12= 807 ayl/min
n₂₀= 807 *1.12= 904 ayl/min
n₂₁= 904 *1.12= 1012 ayl/min
n₂₂= 1012 *1.12= 1134 ayl/min
n₂₃= 1134 *1.12= 1270 ayl/min
n₂₄= 1270 *1.12= 1422 ayl/min

1-Holat uchun
I III II	X1 = 2 X2 = 3 X3 = 4 I – 1 II – X1 – 2 III – X1*X2 - 6

2-Holat uchun
I III II	X1 = 3 X2 = 2 X3 = 4 I – 1 II – X1 – 3 III – X1*X2 - 6

2 - uchun aylanishlar chastatasi grafigi quramiz.
