Tishli uzatma aniqlik darajasini tanlashni yaxshilang. Ko&#39;pgina ko&#39;taruvchi kranlar 8-darajali ishlab chiqarilgan spiral tishli g&#39;ildiraklardan foydalanadilar. Oddiy kran reduktorlari keyingi aniq pardozlashni hisobga olmaydi, shuning uchun eksantriklik xatosi yuqori nurlanish shovqiniga olib kelishi mumkin. Agar oxirgi pardozlash bosqichida so&#39;ndirish va tishli g&#39;ildiraklarni silliqlash, tish yuzasini tekislash yoki shunga o&#39;xshash ishlov berish ko&#39;rib chiqilsa, 7 yoki 6-darajali aniqlikka erishish mumkin. Bu shovqinni nazorat qilish talablari qat&#39;iyroq bo&#39;lgan ustaxonalar uchun yaxshiroq variant bo&#39;lishi mumkin.<\/p>\n\n\n\n<p>2. Tishli uzatmalar tizimini optimallashtiring. Uzatish tizimi nuqtai nazaridan, yopiq tishli uzatmalar bilan aloqa charchoq kuchi, uzatish nisbati va yuz kengligi koeffitsienti kabi cheklovlarni hisobga olish kerak. Reduktorning shovqin uzatish chastotasi inson eshitishiga sezgir bo&#39;lgan diapazondan uzoqroq tutilishi uchun, bu cheklovlarni sezilarli darajada o&#39;zgartirmasdan, tishli uzatmalar moduli, tish kengligi va harakatlantiruvchi tishli uzatmalar tish raqamini biroz sozlash uchun genetik algoritmdan foydalanish mumkin.

Korpusni optimallashtirishning asosiy maqsadi uning tabiiy chastotasini yaxshilashdir. Ko&#39;p bosqichli parallel valli uzatish tizimining dastlabki o&#39;nta tabiiy chastotasi odatda past, odatda 50-500 Gts oralig&#39;ida bo&#39;ladi va harakatlantiruvchi mexanizmning aylanish chastotasi va uning garmonikalari bilan osongina mos kelishi mumkin, bu esa rezonansga olib keladi. Reduktor tuzilishiga asoslanib, materialni ma&#39;lum pozitsiyalardan olib tashlash mumkin. Bu nafaqat material narxini tejashga, balki reduktorning tabiiy chastotasini oshirishga va eksantriklik xatosi tufayli yuzaga keladigan g&#39;ayritabiiy shovqinni samarali ravishda kamaytirishga yordam beradi.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"4-conclusion\">4 Xulosa<\/h2>\n\n\n\n<p>Ushbu maqolada ko&#39;taruvchi kran va uning reduktori tadqiqot ob&#39;ekti sifatida olinadi va reduktorning g&#39;ayritabiiy shovqiniga reduktor juftligining eksantrikligi xatosining ta&#39;siri tahlil qilinadi. Xulosalar quyidagicha:<\/p>\n\n\n\n<p>1. Eksentsisitet xatosi hisobga olinganda, boshqariladigan tishli g&#39;ildirakning burchak tezligi muntazam tebranishlarni ko&#39;rsatadi.
