(1) Bosimni kamaytirish
Bosimning pasayishi ishqalanish kuchini birlik maydoniga kamaytiradi. Kontakt maydonini oshirish va yukni kamaytirish bosimni kamaytirish uchun ishlatilishi mumkin. Masalan, hidoyat ray yuzasining tekisligini yaxshilash va sirt pürüzlülüğünü tozalash haqiqiy aloqa maydonini oshirishi mumkin. Qo'shimcha, hidoyat ray yuzasini kengaytirish va harakatlanuvchi hidoyat rayining uzunligini uzaytirish ham aloqa maydonini oshirishi mumkin, lekin bu qo'llab-quvvatlovchi strukturaning qattiqligiga moslashtirilishi kerak. Aks holda, yuklangandan keyin ortiqcha deformatsiya, notekis aloqa, va mahalliy bosim oshishi mumkin, yanada kengroq va uzunroq hidoyat relslarini samarasiz qiladi. Bundan tashqari, yo'naltiruvchi rayni uzaytirish va kengaytirish texnik qiyinchilikni oshiradi; yo'naltiruvchi temir yo'l yukini kamaytirish uchun tushirish usullarini qo'llash mumkin.
(2) Ishqalanish koeffitsientini kamaytiring
Sürgülü ishqalanish juftlarini dumaloq ishqalanish juftlari bilan almashtirish ishqalanish koeffitsienti va aşınmasını sezilarli darajada kamaytirishi mumkin., Bu tosh kesish mashinalarida kamdan-kam qo'llaniladi. Sürgülü juftliklarda, soqol yog'ini to'g'ri tanlash aralash koeffitsientni o'zgartirish orqali ishqalanish ko'rsatkichlarini optimallashtirishi mumkin. Qo'shimcha, soqol yog'ini toza saqlash juda muhim, chunki iflos yog' haddan tashqari aşınmaya olib kelishi mumkin. Sirkulyant moylash sovutish va yuvishni ta'minlagan holda etarli miqdorda moylashni ta'minlaydi. Samarali moylash uchun hidoyat ray yuzasiga moylash moyini teng ravishda taqsimlash, o'yiqlar hidoyat ray yuzasiga kesilishi mumkin. Yog 'viskozitesini to'g'ri tanlash ishqalanish koeffitsientini samarali ravishda kamaytirishi mumkin. Yo'naltiruvchi relsli moylash moyining yopishqoqligi ish sharoitlari va moylash usullariga qarab tanlanishi kerak.; masalan; misol uchun, 20# oil can be used for low-load (pressure > 0.1MPa), high-speed, small to medium-sized stone cutting machines feed guide rails; 30# yoki 40# oil can be used for medium-load (pressure > 0.2MPa), low to medium-speed machine guide rails (most feed guide rails fall into this category); heavy-duty, low-speed machinery guide rails can use 40#, 50#, yoki 70# oil (pressure > 0.4MPa); guide rails prone to dirt contamination should use low viscosity lubricating oil to prevent debris buildup and rail damage.
(3) Correct Selection and Heat Treatment of Friction Pair Materials
Proper selection of friction pair materials can lower the friction coefficient, while heat treatment can enhance wear resistance.
(4) Strengthen Protection
Enhanced protection effectively improves the wear resistance of friction pairs, preventing dust, abrasive particles, and water mist from entering the friction pair. One important method to prevent or reduce wear of guiding pairs is to protect guide rails. Statistics show that protected guide rails can reduce wear by about 60% compared to exposed guide rails. When designing and selecting protective devices for guide rails, the following requirements should be considered: seal the guide rail surface to isolate it from various abrasives; if sealing is not feasible, protective devices should thoroughly remove dust that falls on the guide rail to prevent it from entering the friction pair; the device should withstand coolant corrosion; the structure should facilitate easy installation and removal for cleaning the guide rail and should possess sufficient strength and rigidity, particularly for heavy-duty machinery guide rail protection devices.
Bundan tashqari, factors such as ease of manufacturing, arzon, uzoq xizmat muddati, va estetik ko'rinishga ham e'tibor qaratish lozim. Bir nechta umumiy himoya usullari joriy etilgan:
Scraper turi
Bu usul hidoyat rayidagi changni qirib tashlaydi va bilvosita himoya vositasidir.
Qopqoq plitasi turi
Qopqoq plitani himoya qilish moslamalarining ko'pchiligi harakatlanuvchi hidoyat rayining ikkala uchida ham plitalarni o'rnatadi. Ish stoli harakatlanayotganda, qopqoq plitalari ochiq hidoyat ray sirtlarini qoplaydi, chiplarning hidoyat ray yuzasiga tushishiga yo'l qo'ymaslik. Ushbu qurilma odatda qirg'ichdan himoya qilish moslamalari bilan birgalikda ishlatiladi.
