buyurtma to ta'minlash ta'minlash mumkin mashina yoki komponentlar barqaror yig'ilishi mumkin va bajarish shartlari belgilangan da ko'rsatilgan dizayn, va bu disassembly va montaj qulay%% 2c the montaj tuzilishi orasidagi the parts must the yig'uvchi jarayon talablariga javob berishi kerak. Shuning uchun loyihalash va chizish montaj chizmalari, oqilona yig'ish tuzilishi va jarayon masalalari ko'rib chiqilishi kerak kerak.

1. Raqam of kontakt yuzalari
1. The number of contact surfaces. Two parts can only have one pair of contact surfaces in the same direction (lateral, vertical or radial). This can not only ensure good contact, but also reduce processing requirements. Otherwise, processing will be difficult and it will not be possible. will be contacted at the same time. As shown in Figure 1, a >a ishlangan bo'lishi kerak.

2. The fit between the journal and the hole is as shown in Figure 2. Since the margin φA has already formed a fit, φB and φC should no longer form a matching relationship, that is, φB>�% 86C boʻlishi kerak saqlash.
3. Cone surface fit Since the cone surface fit can simultaneously determine the axial and radial positions, when the taper hole is blocked, there must be a gap between the top of the cone and the bottom of the taper hole. As shown in Figure 2, L2>L1 must be maintained, other a stable fit will not be ed. The standard values of cone taper and taper angle.

4. The Contact surfaces of structural parts in in both directions at the turnning point be chamfered, yumaloq yoki grooved to ta'minlash yaxshi kontakt ikkala yo'nalishda ikkala yo'nalishda. The burilish nuqtalari kerak kerak yo'nalishlar. The burilish nuqtalari kerak yo'nalishlarda bo'lishi kerak emas be ishlanmagan o'ng burchak burchak yoki yumaloq burchaklar of of the same size, chunki bu sabab aralashuv at at the da the burilish nuqtalari yig'ilishi davomida 2c natijada noto'g'ri kontakt va ta'sir montaj aniqligi. As ko'rsatilgan in in Shakl 3.

2. Oqilona tuzilma ning ipli ulanishi tartibi tartibi uchun qattiq 2c an undercut groove bo'lishi kerak chap da bo'lishi kerak ishlang the the screw hole, ko'rsatilgan teshik, sifatida ko'rsatilgan shakl 4. In tartibi uchun yaxshi kontakt oralig'ida bog'lovchi bo'lak va ulangan bo'lak, ulangan bo'lak 2c bo'lishi kerak a qarshi yoki boshliq, as sifatida bo'lishi kerak bo'lishi shakl 4da ko'rsatilgan. The diameter of the hole of the connected parts be katta katta diametr of the thread or the diameter of the vida to oson yig'ish.

3. Oqilona struktura uchun axial fiksatsiya of rolling bearings. In order to prevent axial movement of rolling bearings, a certain structure must used to fix the same ring and seat ring. Commonly used axial fixed structural forms include include : shaft yelka, yelka, yelka, yelka, elastik qoldiruvchi halqa, to'g'irlash partiyasi qopqoq qopqog'i flange, round nut and backstop yuvuvchi, va shaft end retaining ring, ko'rsatilgan shakl 5. The standard dimensions of retaining rings for holes and shaftoli can found found in the standards. In order make the rolling bearing rotate flexibly and prevent to prevent to getting yopishib keyin termik kengayish, a kichik miqdori axial clearance bo'lishi kerak chapga (umumiy %{0}.%2-0.3mm). Keng ishlatiladigan sozlash usullari ichiga 3a o'rnini metall gaskets of turli qalinliklar yoki yordamida vida thrust plitalar, etc. .

4. Leak-qarshi tuzilishi mashina yoki komponent normal ishlashi mumkin bog'liq bog'liq katta kengligi ga bog'liq muhr yoki chiqish-qarshi tuzilish. Buning sababi, a narsalar quti (kulvert) tez-tez yasalgan bo'ladi a to'ldirish qutisi (kulvert) bu erda bu aylanuvchi shaft va suzuvchi tayoq (val rod, piston rod, va boshqalar)) of the machine or component protrude from the box (or valve body) and filled with soft materials with special properties. For packing, use a bez or nut to compress the packing to lariga yopishqoqligi shaft (tayoq) bilan mos bosim, shunday ki as to to sqinlik harakat ning harakati uchun shaft tayoqcha va oldini olish ish o rta (suyuqlik yoki gaz) dan harakatlanish uchun shaft (tayoq). ) sızıntı, shunday oynash bilan uchun tayoqcharoli sızdırmazlık va sızdırmazlık oldini olish, shaklida ko'rsatilgan shakl 6. Qachon chizilgan rasm 2c da bezi chizilgan bo'ladi bu erda qadoqlash to'ldirilgan to ldirilgan va to plash boshlanadi qattiqlashtirilgan.
