Ukuthwala izindandatho ezibulewe ikakhulukazi kwakhiwa indandatho ephezulu, indandatho ephansi nebhola eligcwele eliphelele. Lonke umklamo wendandatho yokubulala usetshenziselwa ukujikeleza izixazululo ngejubane eliphansi nemithwalo ekhanyayo. Imiklamo emibili emibili kanye nemiklamo eluhlaza okomule kabili, kanye lula izimbobo zokukhwela ezihlanjululwe ngaphambili.

Empilweni yangempela yokuqina kokuqina, umehluko wesisindo wokwenza okubandayo ungalawulwa ngo-1%, ukujula kokuwohloka kungu-0.5mm, ukufakwa kobuso bokuphela kungaphansi kwama-2 ° 30, futhi umehluko wesisindo ngokukhanya okushisayo kungakapheli ama-3 °.

Ukuphoqa ukufutheka kufa, okungukuthi, ukukhawulela i-warpage, ukunyakaza kwe-axial, futhi usike ukugcwala kwebha ngokuqina kwe-radial. Ezinye zalezi zindlela ziqiniswa kuphela ekugcineni kommese ohleliwe, kanti ezinye ziqiniswa ekugcineni kommese ohleliwe kanye nokuphela kommese oshukumisekayo. Izindlela zokuqinisa zifaka uhlobo lwe-cylinder kanye nendlela yokuxhumana.

Ukuqina okubulewe kungummeleli ophethe ukuhanjiswa okuhlukahlukene okusetshenziswayo. Isetshenziselwa ijubane eliphezulu noma ijubane eliphezulu kakhulu futhi lihlala isikhathi eside kakhulu. Lolu hlobo lokuthwala lunempikiswano ephansi, isivinini esikhulu somkhawulo, isakhiwo esilula, izindleko eziphansi, futhi kulula ukufeza ukunemba okuphezulu kokukhiqiza.

Ukuthwala izindandatho ezibule futhi kunekhono elithile lekhono lokugxila. Lapho kuthambekele kuma-degree ayi-10 ahlobene nomgodi wezindlu, kusasebenza ngokujwayelekile, kepha kunomthelela othile empilweni yomthwalo. Ama-Slew WELWEng Ring ethwele amakheji amakheji ensimbi ahlanganiswe kakhulu, futhi amabhere amakhulu ikakhulukazi amakheji aqinile ezemidlalo aqinile. Ukubekwa uphawu kokuqina kwendandatho ebunzi bokuvimbela ukugcwala amafutha agcwaliswe kungavuza ngakolunye uhlangothi, futhi ngakolunye uhlangothi ukuvimba uthuli lwangaphandle, ukungcola kanye nomswakama kusuka ekungeneni okungaphakathi kokuthwala nokuthinta ukusebenza okujwayelekile.

Njengoba ukugeleza okubungu okuningi kusebenza ngaphansi komthwalo osindayo kanye nesivinini esiphansi, uhlobo lokubopha uphawu lokwamukela izakhiwo ezimbili: uphawu lwe-rubber seal ring seal kanye nophawu lwe-labyrinth. I-Rubber Seal Ring Seal ngokwayo inesakhiwo esilula. Kusetshenziswe kabanzi ngenxa yokusebenza kwayo okuncane kwesikhala nokusebenza okuthembekile kokusebenza uphawu. Kodwa-ke, ukushiyeka kwalo ukuthi izindebe zokubopha irabha zithambekele ekugugeni kusenesikhathi ekushiseni okuphezulu futhi kulahlekelwa ukusebenza kwalo kokubekwa uphawu. Ngakho-ke, izindandatho ezibulewe ezithwala ezisebenza ngaphansi kwezimo zokushisa eziphakeme zifanele ukusetshenziswa kwe-labyrinth seal.
