Kodi mphamvu ya ma bearing a gasi a granite ndi yotani?

Mu makampani opanga zinthu, zida zamakina ndi zida zofunika kwambiri zomwe zimathandiza kupanga zida ndi zida zolondola. Gawo limodzi lofunika kwambiri la zida zamakina ndi spindle, yomwe imanyamula chida chodulira ndikuzungulira mwachangu kwambiri kuti ichite ntchito zodulira. Spindle iyenera kuyikidwa pa mabearing omwe amatha kupirira kulemera kwake ndikupirira mphamvu zomwe zimapangidwa panthawi yodulira.

Mwachikhalidwe, ma bearing a mpira ndi ma roller bearing akhala mitundu yogwiritsidwa ntchito kwambiri ya ma bearing mu zida zamakina. Komabe, chifukwa cha kufunikira kwakukulu kwa kulondola ndi magwiridwe antchito, mitundu yatsopano ya ma bearing yapangidwa, monga ma bearing a gasi. Ma bearing a gasi ndi ma bearing osakhudzana omwe amagwiritsa ntchito filimu yopyapyala ya gasi, nthawi zambiri mpweya kapena nayitrogeni, kuti athandizire chinthu chozungulira. Amapereka zabwino zingapo kuposa ma bearing achikhalidwe, monga kupsinjika kochepa, kuthekera kwa liwiro lalikulu, komanso kunyowetsa bwino.

Chinthu chimodzi chomwe chagwiritsidwa ntchito bwino ngati chinthu chonyamulira mpweya mu zida zamakina ndi granite. Ma granite gas bearing ali ndi zinthu zingapo zapadera zomwe zimawapangitsa kukhala chisankho chokongola pakugwiritsa ntchito bwino kwambiri. Granite ndi chinthu chachilengedwe chomwe chimapangidwa kuchokera ku magma yozizira, ndipo chili ndi kapangidwe kake kakang'ono komanso kofanana. Izi zimapangitsa kuti ikhale yolimba kwambiri pakuwonongeka ndi kusinthika, ngakhale ikanyamula katundu wolemera komanso kuthamanga kwambiri.

Ma bearing a gasi a granite alinso ndi chiŵerengero chachikulu kwambiri cha kuuma ndi kulemera, zomwe zikutanthauza kuti amatha kuthandizira kulemera kwakukulu popanda kupotoka kwambiri. Izi ndizofunikira kwambiri pazida zamakina, komwe spindle imatha kulemera makilogalamu mazana angapo ndipo iyenera kuyikidwa molondola kwambiri. Kuphatikiza apo, granite ili ndi coefficient yochepa kwambiri ya kutentha, zomwe zikutanthauza kuti sichitha kusinthika chifukwa cha kusintha kwa kutentha. Izi ndizofunikira kwambiri pazida zamakina, komwe kusintha kwa kutentha kungayambitse kusintha kwakukulu pakukula kwa zigawo zomwe zikupangidwa.

Kuchuluka kwa mphamvu ya ma bearing a gasi a granite kumadalira zinthu zingapo, monga kukula ndi mawonekedwe a bearing, momwe imagwirira ntchito (liwiro, kutentha, kupanikizika), ndi mawonekedwe a granite. Kawirikawiri, ma bearing a gasi a granite amatha kunyamula katundu kuyambira ma Newton angapo mpaka ma kilo-Newton angapo, kutengera kukula ndi kapangidwe ka bearing. Amathanso kugwira ntchito pa liwiro lofika mpaka masauzande angapo a ma revolutions pamphindi, zomwe ndi zapamwamba kwambiri kuposa ma bearing achikhalidwe a ball or roller.

Pomaliza, ma granite gas bearing ndi ukadaulo wabwino kwambiri wogwiritsa ntchito mwachangu komanso molondola kwambiri mu zida zamakina. Amapereka zabwino zingapo kuposa ma bearing achikhalidwe, monga kupsinjika pang'ono, kuthekera kwa liwiro lalikulu, komanso kunyowetsa bwino. Mphamvu yonyamula ma granite gas bearing imadalira zinthu zingapo, koma imatha kuthandizira katundu wambiri ndikugwira ntchito mwachangu kwambiri. Ndi kafukufuku wopitilira ndi chitukuko, ma granite gas bearing akhoza kukhala gawo lokhazikika mu zida zamakina zamtsogolo.
