Kunyamula zinthu ndi magwiridwe antchito

Chingwe cholumikizira ndi chozungulira cha chogwirira chozungulira chimayikidwa mobwerezabwereza ndi mphamvu yayikulu yolumikizana pamene chikugwira ntchito yozungulira ndi kutsetsereka. Chosungiracho chimakhala cholumikizana ndi mbali imodzi ya chingwe cholumikizira ndi chogwirira, kapena mbali imodzi yake, ndipo chimalandira mphamvu yogwirana ndi kugwedezeka mbali imodzi. Chifukwa chake, chidziwitso, magwiridwe antchito, ndi zofunikira zofunika pa chingwe cholumikizira, chogwirira ndi khola ndi izi.

1. Magwiridwe ntchito opemphedwa ndi deta ya ferrule ndi rolling element: mphamvu yogoba yotopa, kuuma kwambiri, kukana kuvala kwambiri
2. Magwiridwe antchito opemphedwa ndi deta ya rack yokonza: kukhazikika kwabwino, mphamvu yayikulu yamakina
3. Kuphatikiza apo, imafunika kukonzedwa. Kutengera ndi momwe imagwiritsidwira ntchito, imafunikanso kukhala ndi kukana kwabwino kwa kukhudza, kukana kutentha komanso kukana dzimbiri.
4. Zambiri zokhudza ma ferrule ndi zinthu zozungulira: ma ferrule ndi zinthu zozungulira nthawi zambiri zimapangidwa ndi chitsulo chokhala ndi chromium yambiri ya kaboni. Ma bearing ambiri amagwiritsa ntchito SUJ2 mu chitsulo cha JIS. Ma bearing akuluakulu amagwiritsa ntchito SUJ3.

Kapangidwe ka mankhwala ka SUJ2 kasinthidwa kukhala chinthu cholumikizira m'maiko osiyanasiyana padziko lonse lapansi. Mwachitsanzo, ndi mtundu womwewo wa chitsulo monga AISL52100 (USA), DIN100Cr6 (West Germany), BS535a99 (UK).
Kuphatikiza apo, pankhani yokana kugwedezeka, chitsulo cha chrome, chitsulo cha chrome molybdenum, chitsulo cha nickel chrome molybdenum, ndi kuuma kwa kaboni zimagwiritsidwa ntchito ngati deta yolumikizira kuti chitsulocho chikhale ndi gawo lofewa kuyambira pakuwoneka mpaka kuzama koyenera. Bearing yolumikizidwa ndi carburing yokhala ndi kuzama koyenera kofewa, kapangidwe kake kabwino, kuuma koyenera komanso kuuma kwapakati kumakhala ndi kukana kwakukulu kokhudzana ndi kugwedezeka poyerekeza ndi chitsulo cholumikizira bearing, komanso kapangidwe ka mankhwala a chitsulo cholumikizira carburing. NSK yakhazikitsa vacuum degassing, kotero deta yomwe imagwiritsidwa ntchito ndi yoyera kwambiri, mpweya wochepa komanso yabwino. Kenako, njira yoyenera yotenthetsera yatengedwa kuti ikonze kwambiri moyo wotopa wa bearing.
Kuwonjezera pa zitsulo zomwe zatchulidwa pamwambapa, chitsulo chothamanga kwambiri chomwe chimalimbana ndi kutentha komanso chitsulo chosapanga dzimbiri chomwe chimalimbana ndi dzimbiri chimagwiritsidwa ntchito kutengera momwe chimagwiritsidwira ntchito.
