Kusanthula Kwathunthu kwa Ma Model Opangira Singano

Ma bereji ozungulira singanoamagwiritsidwa ntchito kwambiri popanga makina ndi kukonza zida chifukwa cha katundu wawo wambiri komanso kapangidwe kake kakang'ono. Komabe, akatswiri ambiri ndi mainjiniya ogulitsa akusokonezekabe ndi mayina ambiri a mitundu, kuphatikizapo NATR, NAKD, ndi KR. Nkhaniyi, yochokera pa muyezo wa dziko lonse wa GB/T 272, "Rolling Bearing Designation Method," ikupereka kusanthula kwakuya kwa malingaliro a needle roller bearing designation, kuthandiza akatswiri kudziwa bwino njira zosankhira.

 

1. Kuzindikira Chiyambi Cha Mawu: Tanthauzo la Ma Prefixes ndi Ma Basic Models

 

Singano yozungulira yozunguliraMa model saperekedwa mwachisawawa; amatsatira malamulo okhwima olembera. Ma core design nthawi zambiri amakhala ndi "ma significant design" otsatiridwa ndi suffix, pomwe ma significant design amavumbula mtundu wa bearing ndi mawonekedwe ake.

 

Mndandanda wa NA: ikuyimira mabearing a singano opanda mphete yamkati. Mabearing awa amagwiritsa ntchito shaft journal ngati msewu wamkati wa mphete, kusunga malo ndipo ndi oyenera kugwiritsidwa ntchito ndi malo olimba a shaft.

 

Mndandanda wa NK: mabearing a singano okhala ndi mphete yamkati amapereka kapangidwe kokhazikika ndipo ndi oyenera kuthamanga kwambiri kapena ngati shaft hardware si yoyenera kugwiritsidwa ntchito mwachindunji pa raceway.

 

Mndandanda wa KR: Amagwiritsa ntchito makamaka mabearing a roller needle roller okhala ndi ma shaft olumikizidwa. Amagwiritsidwa ntchito kwambiri ponyamula zida ndi njira zoyendetsera njanji, zomwe zimapangitsa kuti zikhale zosavuta kuyika komanso kuti katundu azinyamula katundu wambiri.

 

NATR / NATV:Izi ndi mabearing a singano okhala ndi mphete yakunja yopingasa komanso opanda mphete yamkati. TR imatanthauza mphete yakunja yopingasa komanso kapangidwe kopezera malo, pomwe V imayimira zowonjezera zonse za singano zopingasa (zopanda khola). Ndi oyenera kuthamanga pang'ono komanso katundu wolemera.

 

Langizo: Kusiyanitsa ngati chogwirira chili ndi mphete yamkati ndi gawo loyamba posankha chogwirira. Mitundu yopanda mphete yamkati imapereka ndalama zochepa komanso miyeso yaying'ono ya radial, koma imafuna kuuma kwa shaft komanso mtundu wapamwamba.

 

II. Khodi Yowonjezera: Chisindikizo, Khola, ndi Mtundu wa Mphete Yakunja

 

Kalata yomalizayi imafotokoza mwatsatanetsatane momwe bearing imagwirira ntchito ndipo imakhudza mwachindunji malo ogwirira ntchito komanso nthawi ya moyo.

 

Kugwiritsa Ntchito Tanthauzo la Chimangirizo

 

-2RS Zisindikizo za rabara za mbali ziwiri: Zosagwira fumbi ndi madzi, zoyenera malo okhala ndi chinyezi kapena fumbi.

 

-Z Chivundikiro cha fumbi cha mbale yachitsulo cha mbali imodzi: Chimateteza ku tinthu tating'onoting'ono tambiri ndipo chimapereka magwiridwe antchito apamwamba kwambiri poyerekeza ndi mitundu yotsekedwa.

 

Mphete yakunja ya X Cylindrical (yosaoneka ngati kamera): Yoyenera kugwiritsidwa ntchito pofunikira kulondola kwambiri.

 

Khola la TV Polyamide: Limachepetsa kulemera ndipo limawonjezera liwiro lalikulu.

 

Mwachitsanzo, NA4904-2RS imasonyeza chogwirira cha singano chamkati cha mainchesi 20 chomwe chilibe mphete yamkati, chokhala ndi zisindikizo za rabara za mbali ziwiri. Choyenera ma mota ang'onoang'ono kapena ma gearbox.

 

3. Kodi Mungagwirizanitse Bwanji Ma Modeli Mwachangu? Njira Yosankhira ya Masitepe Atatu

 

Dziwani zofunikira pa kapangidwe kake: Kodi flange ikufunika kuti ipezeke? Kodi shaft iloledwa kugwira ntchito ngati msewu wothamanga?

 

Chongani tebulo lokhala ndi miyeso: Sankhani chitsanzo choyambira kutengera malo oyika (m'mimba mwake wamkati, m'mimba mwake wakunja, ndi m'lifupi).

 

Onjezani mawu owonjezera kutengera momwe ntchito ikuyendera: Ganizirani zinthu monga kutseka, mafuta, ndi liwiro kuti musankhe mtundu woyenera.

 

Ndikofunikira kuyerekeza chithunzi cha kapangidwe ka magawo osiyanasiyana m'buku lazinthu ndi tebulo la magawo kuti mumvetse bwino kapangidwe ka mkati ndi njira yoyikira.

 

Kudziwa bwino dongosolo la kusankha anthumabearing a singanoSikuti zimangosonyeza luso laukadaulo komanso ndikofunikira kwambiri pakukweza ukatswiri wautumiki. Kumvetsetsa mfundo za uinjiniya zomwe zili kumbuyo kwa maudindo monga NA, KR, ndi -2RS kungathandize kwambiri kusankha, kugula, komanso kuthetsa mavuto.
