Kodi chimayambitsa phokosoli ndi chiyani?

Phokoso la m'mbali mwake lingayambitsidwe ndi zinthu zingapo, koma pafupifupi zonse zimagwirizana ndi kugwedezeka.Tiyeni's kukambiranamomwe mtundu, kusankha koyenera komanso koyenera mafuta kungakhudzire kuchuluka kwa kugwedezeka ndi phokoso mu mayendedwe.

 

Phokoso lochokera ku berelo nthawi zambiri limagwirizanitsidwa ndi mayendedwe owonongeka a magalimoto. Pamene mayendedwe a magudumu awonongeka, phokoso lambiri ndilo njira yosavuta yodziwira kuti mayendedwe athyoka. Koma, nanga bwanji ma bearings mu ntchito zina?

 

Mipira yokhala ndi mphete ndi mipira sizozungulira bwino. Ngakhale pambuyo popera bwino kwambiri ndi kupukuta, mipira ndi njira zothamanga sizikhala zosalala bwino. Zolakwika izi zimatha kuyambitsa kugwedezeka kosafunikira, komwe kungathe kuwononga mayendedwe ake nthawi yamoyo wake.

 

Nthawi zambiri, pamakhala zolakwika zamakina mwa mawonekedwe azovuta kapena zosagwirizana zomwe zimapangitsa mphete imodzi kusuntha kapena kusuntha mozungulira molingana ndi inzake. Kuchuluka ndi liwiro la kayendedwe kameneka kumathandizira kuchuluka kwa kugwedezeka kwa kunyamula ndi kubereka phokoso.

 

Mipira yoyipa kapena yowonongeka kapena njira zothamangira, mpira wosayenda bwino kapena msewu wothamanga, kuipitsidwa mkati mwa mayendedwe, kusakwanira kwamafuta, shaft yolakwika kapena zololera zanyumba komanso kusewerera kolakwika kwa ma radial kungayambitse kugwedezeka kwa chimbalangondo ndipo kenako, zitha kukhala zomwe zimapangitsa kuti phokoso lambiri.

 

Mukasaka chotengera chokhala ndi phokoso lotsika, kunyamula kwabwino kumakhala ndi mapeto abwino kwambiri pamipira ndi mpikisano. Panthawi yopanga, kuzungulira kwa mipira ndi mphete zonyamula zidzayendetsedwa kwambiri. Kusalala kapena chete kwa bere kumatha kuwunika ndi ma accelerometers omwe amayesa kugwedezeka kwa mphete yakunja, nthawi zambiri mphete yamkati imazungulira 1800 rpm.

 

Njira ina yothanirana ndi phokoso ndikutchula sewero la ma radial lomwe limalola kuti chiwonetserocho chizigwira ntchito pafupifupi zero sewero la radial likagwiritsidwa ntchito. Ngati kutsetsereka kwa shaft kapena nyumba sikuli kolakwika, kunyamula kumatha kukhala kolimba kwambiri, komwe kungayambitse phokoso lalikulu. Momwemonso, shaft yosauka kapena kuzungulira kwa nyumba kumatha kusokoneza mphete zonyamula, zomwe zimatha kukhudzanso kugwedezeka ndi phokoso la chotengera.

 

Kuyika koyenera ndi chinthu china chofunikira kuganizira. Kusakwanira kokwanira kumatha kuyambitsa madontho munjira zonyamula katundu zomwe zimawonjezera kugwedezeka. Momwemonso, zoipitsa m'ma bearings zimatha kuyambitsa kugwedezeka kosafunika.

 

Kuti phokoso likhale lochepa, chonyamulira chiyenera kukhala chopanda zowononga. Ngati kunyamula sikugwiritsidwa ntchito pamalo oyera kwambiri, chitetezo ku dothi, monga zisindikizo zolumikizirana, ziyenera kuganiziridwa.

 

Pamayendedwe abwino, mafuta opaka phokoso amalimbikitsidwanso. Monga momwe dzinalo likusonyezera, mafuta osasefedwa bwinowa adzalola kunyamula kuyenda mwakachetechete chifukwa chosowa tinthu tating'onoting'ono tolimba. Tsopano pali zosankha zambiri zokhudzana ndi mafuta otsika phokoso, ndi zosankha zingapo pamsika.
