Ama-roller bearings e-needle alignment e-PNA12/28, anendandatho yangaphakathi
Ama-bearings e-needle roller anendandatho yangaphandle enobuso obungaphandle obuyindilinga. Amasongo amabili okuhlala e-polymer ane-inside surface e-sphere afakwe esikhwameni sensimbi esidwetshiwe futhi afakwe phezu kwendandatho yangaphandle. Lo mklamo wenza i-bearings ikwazi ukwamukela ukungalungi kahle kwe-shaft maqondana ne-housing. Ezisetshenzisweni lapho i-shaft ingenakuqiniswa futhi igaywe, ama-bearings ane-inside ring kufanele asetshenziswe. Ukufuduka kwe-axial okuvunyelwe kwe-shaft maqondana ne-housing kunqunyelwe kuma-bearings ane-inside ring. Uma ukufuduka kwe-axial okuvunyelwe okuhlinzekwa yi-inside ring ejwayelekile kunganele, kungenzeka ukusebenzisa i-inside ring ende.
Ama-bearings angenandandatho yangaphakathi ayisinqumo esihle kakhulu sokulungiselela ama-bearings amancane, uma umgodi ungaqiniswa futhi ugaywe.
Izici ze-PNA12/28 Alignment needle roller bearings
Vumela ukungalungi kahle kwe-static: Ama-roller bearings e-needle ahambisanayo ayazilungisa ngokwawo aze afike ku-3° wokungalungi kahle kwe-static.
Ingxenye ephansi yesiphambano: Ezinhlelweni zokusebenza lapho isikhala sincane khona, ama-roller bearings e-needle ahambisanayo anikeza ikhambi elincane.
Umthamo wokuthwala ophezulu: Ngenxa yenani elikhulu lama-roller, ama-roller bearings e-alignment anesisindo esikhulu sokuthwala umthwalo.
