Bayani dalla-dalla game da bearings na injin Aero

Siffofin gini:

Bearings na injin Aero: bisa ga ɓangaren amfani, ana iya raba shi zuwa rukuni uku: bearings na spindle, bearings na gearbox na kayan haɗi da bearings na gearbox mai ragewa.

1. Ƙarfin juyi

Bearings na spindle suna tallafawa rotors na fanka na injin, rotors na janareta na gas da rotors na turbine mai ƙarfi, yawanci suna amfani da haɗin bearings na ball contact bearings masu maki uku da bearings na cylindrical, bearings na ball contact bearings masu maki uku suna ɗaukar nauyin axial da nauyin radial na rotor, bearings na cylindrical na ɗaukar nauyin radial kawai, kuma halayen aiki na bearings na spindle shine babban saurin juyawa (ƙimar dn har zuwa 2.6 × 106 mm · r/min), babban zafin jiki (180 ~ 250 °C, na ɗan gajeren lokaci ya fi 300 °C), babban nauyin axial, nauyin haske na ɗan gajeren lokaci da nauyin lodi a cikin alkiblar radial, alkiblar canza nauyin axial da ƙaramin sararin shigarwa. Saboda haka, bearings na spindle suna da matakan haƙuri masu yawa, gabaɗaya ba su ƙasa da matakin P4 ba, kuma suna da tsauraran buƙatu don daidaiton injinan rollers na cylindrical; Bugu da ƙari, bearings na spindle galibi ana shafa mai a ƙarƙashin zobe, wanda ke buƙatar ƙira ta musamman da ta dace.

 

2 gearbox na watsawa na kayan haɗi

 

Bearing na gearbox transmission gear yana tallafawa gear rotor na tsarin transmission system, kuma halayen aikinsa sune ƙananan kaya, ƙarancin zafin jiki (120 ~ 150 °C), da ƙarancin saurin juyawa (ƙimar dn ba ta fi 1.5 × 106 mm · r/min ba)

 

3 Gearbox mai rage zafi

 

Haɗin gear mai ɗaukar nauyin gear mai rage nauyin gear, halayen aikinsa sune babban kaya, ƙarancin gudu da ƙarancin zafin jiki (120 ~ 150 °C).

 

Bukatun gabaɗaya

Saboda yanayin amfani da injinan aero, buƙatun gabaɗaya na bearings sun fi tsauri fiye da na bearings na yau da kullun, kuma buƙatun da suka dace sune kamar haka.

 

1. Yana jure wa zafin jiki mai yawa lokacin ajiye motoci

 

Idan injin yana aiki, ana shigar da iska mai sanyi don sanyaya ruwan wukake, bearings da sauran sassa, sannan kuma bearings ɗin ana sanyaya su ta hanyar shafa mai. Duk da haka, bayan rufewa, waɗannan matakan sanyaya ba sa aiki, kuma za a watsa zafin turbine zuwa bearings ta hanyar gidan bearings da shaft, wanda ke haifar da ƙaruwar zafin bearings cikin ɗan gajeren lokaci, musamman zafin bearings na ƙarshen zafi na injin zai tashi ba daidai ba, kuma wasu bayanai na sa ido kan injin sun nuna cewa zafin bearings zai kai kimanin 350 °C.

 

2. Ƙarfin man shafawa mai katsewa

 

Yanayin samar da mai mai na bearings na injin Aero galibi an raba su zuwa rukuni biyu:

1) Kafin injin ya fara aiki yadda ya kamata na tsarin mai mai shafawa, yana cikin yanayin sanyi, tare da ƙarancin gudu da ƙaramin kaya;

2) Idan injin yana aiki, idan tsarin mai mai shafawa ba zai iya ci gaba da samar da mai ba saboda dalilai na musamman, kuma injin yana buƙatar ci gaba da aiki na wani lokaci, mai mai zai kasance cikin mummunan yanayin man shafawa ko ma bushewar aiki, kuma ba za a iya shafa mai da kyau a sanyaya shi ba. Don tabbatar da amincin tashi, mai mai yana buƙatar samun ikon ci gaba da aiki akai-akai na wani lokaci ba tare da lalacewa ba tare da shafa mai ba.
