Rulmanning nosozligi - bu qimmat ishlamay qolish va ta'mirlashga olib keladigan keng tarqalgan muammo. Rulman ishdan chiqishiga bir qancha omillar sabab bo'lishi mumkin, ammo buning oldini olishning bir necha yo'li ham mavjud. Buning sabablarini tushunish va faol choralar ko'rish rulmanning ishlash muddatini uzaytirishga va uskunaning umumiy ishonchliligini oshirishga yordam beradi.
Rulman ishdan chiqishining eng keng tarqalgan sabablaridan biri noto'g'ri moylashdir. Rulman to'g'ri yog'lanmagan bo'lsa, u sirtning qurib qolishiga va ishqalanishga olib kelishi mumkin, bu esa erta aşınma va shikastlanishga olib kelishi mumkin. Buning oldini olish uchun rulmanni muntazam ravishda to'g'ri turdagi moylash materiallari bilan yaxshi yog'lanishini ta'minlash kerak. Bundan tashqari, moylash materialini toza va ifloslantiruvchi moddalardan tozalash muhim ahamiyatga ega, bu esa rulmanlarning ishdan chiqishiga yordam beradi.
Rulmanning ishdan chiqishiga olib kelishi mumkin bo'lgan yana bir omil - bu haddan tashqari issiqlik. Yuqori haroratlar rulmanning o'z imkoniyatlaridan tashqari kengayishiga olib kelishi mumkin, bu esa rulmanning ishdan chiqishiga olib keladi. Bunga turli omillar sabab bo'lishi mumkin, masalan, to'g'ri sovutish mexanizmlarining yo'qligi yoki rulmanga ortiqcha yuk. Haddan tashqari qizib ketishning oldini olish uchun rulmanning to'g'ri tekislanganligini va rulmanda ortiqcha kuchlanishni oldini olish uchun yukning teng taqsimlanishini ta'minlash kerak.
Noto'g'ri texnik xizmat ko'rsatish rulman etishmovchiligining yana bir keng tarqalgan sababidir. Rulmanlarni aşınma, shikastlanish yoki ifloslanish belgilari uchun muntazam ravishda tekshirish kerak. Muammoning yomonlashishiga yo'l qo'ymaslik uchun har qanday muammoni darhol hal qilish kerak. Muntazam parvarishlash va tozalash, shuningdek, rulmanning aşınmasına olib kelishi mumkin bo'lgan axlat va boshqa ifloslantiruvchi moddalarning to'planishining oldini oladi.
Ushbu omillarga qo'shimcha ravishda, birinchi navbatda, rulmanning to'g'ri o'rnatilishini ta'minlash kerak. Noto'g'ri o'rnatish rulmanda stressga olib kelishi mumkin, bu esa muddatidan oldin ishdan chiqishiga olib keladi. Rulmanlarni o'rnatish bo'yicha ishlab chiqaruvchining ko'rsatmalariga rioya qilish va rulmanni to'g'ri tekislash va mahkamlanganligini ta'minlash muhimdir.
Rulmanning ishdan chiqishini oldini olish uchun texnik xizmat ko'rsatish va ta'mirlashga faol yondashish muhimdir. Bunga muntazam tekshiruvlar, tozalash va moylash, shuningdek, yuzaga kelgan muammolarni tezda hal qilish kiradi. Ushbu qadamlarni qo'llash orqali siz podshipniklaringizning ishlash muddatini uzaytirishga va umumiy uskunaning ishonchliligini oshirishga yordam bera olasiz, bu esa operatsiyalaringiz muammosiz ishlashini ta'minlaydi.
