Nne-Pointi Mawasiliano Mpira fani
Utangulizi
Mipira ya miguso yenye pointi nne ni fani za mpira wa mgusano wa safu mlalo moja yenye njia za mbio ambazo zimeundwa kuhimili mizigo ya axia katika pande zote mbili.Kwa mzigo fulani wa axial, mzigo mdogo wa radial pia unaweza kuungwa mkono.Fani zinaweza kutenganishwa, yaani, pete ya nje iliyo na mpira na mkusanyiko wa ngome inaweza kuwekwa kando na nusu mbili za pete za ndani.
Nusu zote mbili za pete za ndani za fani za mpira wa mgusano wa pointi nne zina bega lililowekwa nyuma.Hii inaboresha mtiririko wa mafuta wakati kuzaa kunatumiwa pamoja na kuzaa kwa roller cylindrical.Kwa kuongeza, mapumziko haya yanaweza kutumika kuwezesha kushuka.
Vipengele na Faida
- ●Inachukua mizigo ya axial katika pande zote mbili
- ● Nafasi ndogo ya axial
Fani hizi huchukua nafasi ndogo sana ya axial kuliko fani za safu mbili. - ●Uwezo wa juu wa kubeba mizigo
Idadi kubwa ya mipira imeingizwa, ikitoa kubeba uwezo wake wa juu wa kubeba mzigo. - ● Muundo unaoweza kutenganishwa
Pete ya ndani iliyogawanyika inaongoza kwa upandaji rahisi na kushuka kwa kuzaa. - ●Flo iliyoboreshwa ya mafuta
- Ubadilishaji mdogo wa pete ya ndani wakati unakabiliwa na nguvu za juu za kushinikiza.
Kazi
Wakati mizigo safi tu ya axial inatumiwa, mpira na pete huunda mawasiliano ya pointi mbili yenye uwezo wa kubeba mizigo ya axial ya pande mbili.Vipimo vinne vya kugusa mpira ni sawa.
Inayo mzigo wa torque, ina kazi za kuzaa kwa mpira wa mgusano wa safu ya mstari mmoja na kuzaa kwa safu mbili za mpira wa mguso wa angular.Kuzaa kwa mpira wa alama nne kunaweza kufanya kazi kwa kawaida tu wakati mawasiliano ya pointi mbili yanapoundwa.Kwa hiyo, ni kwa ujumla yanafaa kwa ajili ya wale safi axial mzigo au kubwa axial mzigo chini ya mzigo Composite ya kuwasiliana na pointi mbili, nne kumweka kuwasiliana mpira kuzaa kikomo kasi ni ya juu, lakini pia yanafaa kwa ajili ya matukio hayo ya kasi ya operesheni.
Sifa
Kuzaa kwa mpira wa alama nne ni muundo unaoweza kutenganishwa, na kuzaa moja kunaweza kuchukua nafasi ya kuzaa kwa mpira wa angular na mchanganyiko wa mbele au mchanganyiko wa nyuma.
Inaweza kubeba mzigo wa radial na mzigo wa axial wa pande mbili, na inaweza kupunguza uhamishaji wa axial katika pande mbili, lakini inachukua nafasi ndogo ya axia kuliko vipimo vya sasa vya safu mbili za kuzaa mpira wa mguso wa angular.
Ikilinganishwa na fani nyingine za mpira, fani za mpira wa kugusa wa pointi nne zina kibali kidogo cha axial na kasi ya juu ya kikomo wakati kibali cha radial ni sawa.
Fani za mpira wa alama nne zinafaa kwa kubeba mizigo safi ya axial au mizigo ya pamoja ya axial na radial kulingana na mizigo ya axial.Kutokana na pete ya ndani ya nusu (au pete ya nje), idadi ya mipira imeongezeka na uwezo wa kuzaa ni mkubwa.
Chini ya hali ya kawaida ya kazi, aina hii ya kuzaa inaweza kuunda angle ya kuwasiliana wakati wa kubeba mzigo wa axial katika mwelekeo wowote, na mpira wa chuma unawasiliana na njia za ndani na nje za mbio kwa wakati mmoja ili kuepuka msuguano mkubwa wa sliding katika eneo la mawasiliano.Kwa hiyo, kuzaa haipaswi kuwa chini ya nguvu za radial na mizigo.
