Kodi chosindikizira chosindikizidwa, chokhala ndi mtundu wa chisindikizo

 

Zomwe zimatchedwa kusindikizidwa kosindikizidwa ndizopanda fumbi, kotero kuti chiberekerocho chimasindikizidwa bwino kuti chisamalire bwino kuti chisamalire bwino komanso malo ogwirira ntchito, kupereka masewera onse ku ntchito yobereka, kuwonjezera moyo wautumiki wa kubereka, ndi khalani ndi chisindikizo choyenera cha kugubuduza kuti mupewe kutayikira kwa wothandizira wosalala komanso kuwukira kwa fumbi, nthunzi yamadzi kapena dothi lina. Izi zimathandizira chitetezo cha mthupi.

 

Mtundu wa Chisindikizo:

Tiye kusindikiza chipangizo dongosolo la mayendedwe akugudubuza makamaka ogaŵikana kukhudzana zisindikizo ndi sanali kukhudzana zisindikizo.

 

Kusindikiza kosalumikizana kwa ma bearings

 

Kukhala ndi kusindikiza kosalumikizana ndi njira yosindikizira yomwe imapanga kusiyana kochepa pakati pa shaft ndi chivundikiro chomaliza cha nyumba yonyamula katundu. Mtundu woterewu wosindikizira sukhudzana ndi shaft, kotero palibe kukangana ndi kuvala, ndipo ndi koyenera kusinthasintha kothamanga kwambiri. Kuti muwonjezere mphamvu yosindikiza, kusiyana kumatha kudzazidwa ndi mafuta. Kukhala ndi zisindikizo zomwe sizimalumikizana makamaka zimaphatikizapo: chisindikizo cha gap, seal groove seal, labyrinth seal, oil slinger seal, etc.

 

1. Kusindikiza malire

Chisindikizo cha kusiyana ndikusiya kagawo kakang'ono ka annular pakati pa shaft ndi chivundikiro chonyamula kudzera mu dzenje, kusiyana kwa radius ndi 0.1-0.3mm, kutalika kwake kumakhala kocheperako komanso kocheperako, kumapangitsanso kusindikiza bwino.

 

2. Kusindikiza poyambira mafuta

 

Chisindikizo chamafuta chimakonzedwa ndi groove yamafuta a annular pabowo lamkati la chivundikiro chosindikizira, ndipo poyambira mafuta amagawidwa mozungulira, ndipo mafuta aliwonse amalumikizana kudzera munjira yowongolera mafuta ndikulumikizana ndi thanki yamafuta. , ndi chiwerengero cha annular mafuta poyambira ndi mafuta kalozera groove zimatsimikiziridwa ndi kukula kwa chisindikizo mapeto chivundikirocho.

 

3. Kusindikiza kwa labyrinth

Mfundo yaikulu ya kusindikiza uku ndikupanga njira yothamanga pa chisindikizo ndi kukana kwakukulu kwa kutuluka. Mwamadongosolo, kagawo kakang'ono ka tortuous kamapangidwa pakati pa gawo loyima ndi gawo lozungulira kuti apange "labyrinth".

 

4. Kusindikiza kwa slinger yamafuta

 

Kulumikizana zisindikizo kwa bearings

Kusindikiza kusindikiza ndi njira yosindikizira kumapeto kapena kukhudzana ndi milomo ya rabara yopangidwa ndi vulcanized pa mafupa achitsulo, ndipo kusindikiza kwake kuli bwino kuposa kusindikiza kosalumikizana, koma kukangana ndikwambiri, ndipo kutentha kumakwera kwambiri. Malo olumikizirana a shaft ndi chisindikizo amayenera kupakidwa mafuta, nthawi zambiri ndi mafuta omwewo monga chonyamulira. Zisindikizo zolumikizirana makamaka zimaphatikizapo: kusindikiza mphete, kusindikiza mbale zachikopa, kusindikiza mphete, kusindikiza kwa mafupa, kusindikiza mphete, ndi zina.

 

1. Kusindikizidwa kwa mphete

Mphepete mwa trapezoidal imatsegulidwa pachivundikirocho, ndipo kamvekedwe kabwino ka mbali yamakona anayi amayikidwa mu trapezoidal groove kuti agwirizane ndi tsinde, kapena chithokomiro chimakanikizidwa mwamphamvu kuti mpheteyo imveke ndi kutulutsa mphamvu ya radial kuti igwire. kutsinde, kuti akwaniritse cholinga chosindikiza.

 

2.Chophimba chachikopa chatsekedwa

 

Chophimba chachikopa chosindikizidwa (chopangidwa ndi zinthu monga mphira wokokedwa ndi mafuta) chimayikidwa mu chivundikiro chonyamula ndikukanikizidwa molunjika ku shaft. Pofuna kupititsa patsogolo kusindikiza, kasupe wa mphete amakanikiza mphete yamkati ya mbale yachikopa, kuti mphete yamkati ya mbale yachikopa ikhale yolimba kwambiri ndi shaft..

 

3. Mphete yosindikiza imasindikizidwa

Zisindikizo nthawi zambiri zimapangidwa ndi mphira wachikopa, pulasitiki kapena mafuta ndipo amatha kupangidwa mosiyanasiyana malinga ndi momwe amafunira. Mphete yosindikizira yooneka ngati 0 ili ndi mbiri yozungulira, kudalira mphamvu yake yokhayokha kuti isindikize pa shaft, yokhala ndi mawonekedwe osavuta komanso kusonkhanitsa kosavuta ndi kupasuka. Zisindikizo zooneka ngati J komanso zooneka ngati U zimagwiritsidwanso ntchito kwambiri, ndipo zonsezi zimakhala ndi milomo yooneka ngati milomo.

 

4. Kusindikiza mafupa

 

Pofuna kupititsa patsogolo mphamvu zonse za chisindikizo cha mbale yachikopa, zitsulo zokhala ndi gawo lofanana ndi L ndi mawonekedwe a annular zimayikidwa mu rabara yosagwira mafuta, kotero kuti chisindikizo cha chikopa chikhale chosavuta kupunduka, ndi moyo wautumiki umakhala wabwinoPankhani ya <7m/s, mabokosi ambiri onyamula mapampu apakati pakali pano amasindikizidwa ndi mafupa.

 

5. Kusindikiza mphete yosindikiza

Uwu ndi mtundu wa chisindikizo cha annular chokhala ndi notch, chimayikidwa mumphepo yam'mphepete mwa manja, manjawo amazungulira pamodzi ndi shaft, ndipo mphete yosindikizira imakanikizidwa pakhoma lamkati la gawo loyima ndi kukhazikika komwe notch imakanikizidwa, ndipo imatha kugwira ntchito yosindikiza, ndipo kusindikiza kwamtunduwu kumakhala kovuta kwambiri.

 

Kusankhidwa kwa mawonekedwe osindikizira

 

Posankha kapangidwe ka chisindikizo chonyamulira, mfundo zazikuluzikulu zomwe muyenera kuziganizira ndi: mafuta, ndiko kuti, kaya ndi mafuta kapena mafuta; Liniya liwiro la kusindikiza zigawo; cholakwika cha kukhazikitsa shaft; Kukula ndi mtengo wa malo oyikapo, etc.
