Uxhumano Keyed. Slot uxhumano - GOST. Tolerances keyways compounds

uxhumano Keyed - uhlobo umbono docking izingxenye ezimbili gasketed. Kubalulekile. Kulokhu, izinto ezihlangene element asizayo - Ukhiye.

sphere kwesicelo

zonke lilula kule ndaba. Kusebenza uxhumano keyed ngoba jointing shaft futhi ihabhu. Okungukuthi, ukuze zingasivimbi ukuba co-ligijima ngesikhathi torque engu yokudlulisela. Futhi, asetshenziswa lezi zakhi, nakuba ayengazi kabanzi, ukuvimbela shift indiza izingxenye. Ngayiphi kulandela sicabanga kuphela icala lokuqala.

zinhlobo

uxhumano Key zihlukaniswe amaqembu amaningana:

1. Kuye ngezinga ukuhamba. Lena isici esibalulekile. Kule ndaba, ababonakali ngezikhundla:

• Uxhumano ngezinhlamvu ezihlelwa ngesandla. Kulokhu, a beya Umhlahlandlela noma spigot.
• Namanje kwenezele.

2. Eqenjini lesibili kubhekwa ibutho okuyinto ethatha ngokuhlangana. Kunezinhlobo ezimbili zama:

• Lesengcile. Kulesi amandla uxhumano ekhiqizwa phakathi kwenhlangano. It ikhona eceleni kusuka umsebenzi.
• Unstressed. Kulesi amandla uxhumano ekhiqizwa kuphela uma umsebenzi.

3. compounds zihlukaniswe hlobo dowels esetshenziswa. okungukuthi:

• Prismatic.
• Ingxenye.
• Cylindrical.
• Wedge.
• Tangential.

Ngaphezu kwalokho elichaza uhlobo ikhi ngayinye eceleni. Nokho, okokuqala kumelwe kuthiwe laba izingxenye akhiwa ikakhulu abantu abasuke ephezulu, eliqinile le Steel okulingene: 45, 50, 55. Lona Eqinisweni kweqiniso. Ukuze kwandiswe amandla dowels, nemishayo ekukhiqizeni kwabo ngokuvamile baphathwa ezishisayo. Ithuthukisa izinga yabo.

ukhiye Parallel

Le ngxenye iyona ezintathu izinhlobo. Ukuthi ihlukaniswe yaba iziqondiso, mortgages and ezihambayo. Ngenxa yokuthi i-keyways parallel nzima esikhundleni nomunye ngenxa lithathelwe ngazinye, kungukuthi asetshenziswa ekukhiqizeni emikhulu. Lena ethile zabo eziyinhloko. Enye kusimo Kulokhu yikhono phenduka ngesikhathi bafake.

ukhiye Woodruff

Lolu hlobo akanayo nebubi ezifana kuqala. Ngakho ba kulula ukusebenzisa ekukhiqizeni. Kodwa bafunela kusimo ukuthi zihlale asetshenziswa kabanzi - kungcono cross-section enkulu shaft. Akunakwenzeka ukuzifaka engxenyeni izimisele shaft ukulayishwa.

ukhiye cylindrical

Lena enye eziphilayo ezibalulekile. Zisetshenziswa ikakhulu enisemikhawulweni kushaft. Ukusebenzisa kwabo kudinga ukuthi izinto kuhlanganiswe zihlukile kwabantu kanye ubulukhuni. Lokhu kuvimbela ukusetshenziswa ebanzi lolu hlobo okhiye ekukhiqizeni emikhulu.

ukhiye tangential

Le ngxenye inezingxenye ezimbili. Lolu hlobo nhlonhlo prismatic elinendawo unxande cross-section. Sungula ngazimbili tangential ukhiye i-engela 120-180 degrees. Inzuzo yalezi izingxenye ukuthi impahla yabo isebenza kokucindezelwa futhi lapha kukhona indlela engcono kakhulu yo- inkatho okuhambisanayo ngokumelene lokuhlushwa ohambelana ekucindezelekeni. Yini embi ngalo ukhiye ezinjalo, ungase ucabangele ke idivayisi eziyinkimbinkimbi. Sebenzisa lezi zinguquko izingxenye e imishini esindayo.

nesigaxa ukhiye

Bona ikhomba ngocansi sisebenzisa amandla kokukhuhlana.

Pluses izingxenye wathi:

- uxhumano keyed kulokhu ekwazi ukumelana umthwalo encane Axial.

- Kube umsebenzi omuhle ngaphansi kwethonya imithwalo onhlobonhlobo.

- Akubalulekile ukusebenzisa izingxenye ezengeziwe izobamba ngokumelene ukunyakaza Axial ka Izikhumulo.

Outs izihluthulelo zimi kanje:

- Ukuba yinkimbinkimbi kwayo disassembly phakathi ukulungisa.

- Strong offset kusukela maphakathi isihlobo labaculi eksisi kushaft. Lena qiniso libalulekile.

- Ngiyaqinisa phambi obuphelele iDemo kungenzeka Kit skew eningi futhi runout hhayi ingxenye ayifakiwe lapho eqondiswa (isondo lokugijimisa indiphi elenzelwe into esindayo, igiya).

Tolerances keyways compounds

Lenchazelo nemaloznachimym. Ukuqinisekisa ikhwalithi tolerances ebekiwe compounds keyways. Kubalulekile ukwazi. Ichaza keyed GOST 2.308-79 "uhlelo Enobunye of design imibhalo. Inothi imidwebo amafomu we tolerances kanye evele ". Lokhu kuhambelana base documentary.

Amapharamitha zezinombolo ukusetha tolerances indawo mayelana nobudlelwano ezilandelayo: T (IzA) = 0.6 T (br); T (sim0) = 4.0 T (w).

Lapho lezi abizwa zihlanganisa:

- T (br) - ukubekezelelana keyed slot ububanzi b.

- C (umusi) - wathi ipharamitha impindamqondo.

- T (SIM) - wesimethri ukubekezelelana ukubaluleka ukubaluleka ubukhulu.

Amapharamitha ibalwa idatha eduze izincazelo ejwayelekile. Eqondiswa ukuze lokhu GOST 24643.

Ukutshala compounds keyways

Ukunemba wokugxilisa izingxenye enikeziwe ngokukhetha le ndlela. Kubalulekile ukucabangela. Tolerances ukuchaza izinhlobo ezintathu ezibangela noma lihlala. Lulawulwa amazinga. Senibheka uhlobo imininingwane ngamunye.

kwakwakhe khulula

Lokhu kokwehla isetshenziswa ngaphansi kwezimo ezinzima nge okufanayo yesifunda imithwalo. Isetshenziselwa uxhumano mobile enikeziwe ukukhanya umsebenzi oyisibopho.

uxhumano evamile

Libhekene njengethuba kufanelekile ukuphazamiseka, akudingi ngokuxabana njalo. Yakha Good izimo ezahlukene.

kokuhlangana Friend

Bazimisele ematfuba ethola lokhu kuphazamiseka ezincane cishe ezifanayo esikhathini dowel abafanele jointing nge izingxenye ezimbili (Slots zabo). Umhlangano isetshenziswa inombolo encane obuyela emuva imithwalo.

Ukunqunywa lezi zakhi

Njengoba sekushiwo ngenhla, nolimi ngokuyisisekelo ezenziwe eliphezulu namandla lezinsimbi medium (55, 50, 45). Ukwandisa amandla ingxenye blank ngabo kuvame owabeka ukufudumeza ukwelashwa, ethuthukisa izinga yabo.

Lapho ukwakha ubudlelwane keyed, okuyinto pre-ekubhaleni, ukuphakama futhi ububanzi engxenyeni usebenzisa GOST ejwayelekile 2336-7, ikhumbula ubukhulu shaft. Kulokhu, akukho nzima. Ubude ulimi ukuthatha kuye ihabhu. Qhathanisa lokhu iziqondiso namazinga afanele. Ukukhethwa nemingcele ethile ukhiye ihlolwe ngokusebenzisa amandla uxhumano ukubala ezibalulekile ukhiye. Ekubaleni lena akunandaba ngempela. Ngokwesibonelo, isimo amandla kulokhu ifomula elandelayo:

σsm = F1 / ACM ≤ [σsm].

Lapha, F1 - ipharamitha amandla circumferential a isondo lokugijimisa indiphi elenzelwe into esindayo (H). AFM ndawo phuca (mm²). Lokhu value kunqunywa fomula elandelayo: (0,94h-T1) LP.

Kulokhu, LP = l-key ubude noMnyango imikhawulo oyindilinga. Lokhu ipharamitha ulinganiswa ngamamilimitha. l - is keyed obugcwele.

Amanani e, h, T1 kukhona osayizi ejwayelekile ngokuhambisana GOST 23360 - 78.

[Σsm] - ukubekela kuvunyelwe voltage nciphisa ku (N / mm²). Lapho usebenzisa yensimbi Kit [σsm] sitholwa ebangeni elithile 55 ... 95 N / mm².

Ukusebenza obuphelele ukhiye ibalwa kanje:

LP = 32 - 6 = 26 mm.

Ukunqunywa endaweni kwasani:

ACM = (0.94 · 6 - 3.5) · 26 = 55,64 mm².

Inani F1 ukwamukela izilinganiso etholwe. Kulokhu, F1 = 1200 H.

Ngenxa yalokho, ukubala voltage ukalwe kuyoba:

σsm = 1200 / 55,64 = 21,56 N / mm².

Lokhu kubonisa ukuthi isimo amandla:

σsm = 21,56> [σsm] (55 ... 95 N / mm²).

Izinzuzo uxhumano ukhiye

Lapha ubonakala lokhu okulandelayo:

• Ukwakha okunokwethenjelwa futhi iqine.
• Ziyakwazi kulula zihlangana futhi ukuqaqa.
• eziphansi.
• Ziyakwazi kulula akhiqize.

amaphutha

Kulesi sici, bayaqonda okulandelayo:

• Keyway buthaka kwesigaba shaft futhi ihabhu.
• Ngo compounds eziningi kukhona misalignment. Okungukuthi, abangabantwana ukufuduka eyisihlobo eksisi ihabhu kushaft nohhafu imvume diametrical.
• Emagumbini keyway high voltage ezingeni.
