Hononga patopato. hononga Kāniwha - GOST. Ngā tukunga pūhui keyways

hononga patopato - he ahua o te tirohanga tāmau wāhanga e rua gasketed. He mea nui. I roto i tenei take, ngā tūemi hono ki te huānga pŭpŭ tauturu - matua.

poi o tono

katoa tino ohie i roto i tenei whakaaro. hononga patopato hāngai mō te jointing take me te hub. Ara, ki te ārai ratou i tahi-hurihuri i roto i taipana tuku. Ano, kei te whakamahia ēnei pūhui, ahakoa kahore whānui, ki te ārai i te neke o ngā wāhanga plane. I roto i te mea whai whakaaro tatou te take tuatahi anake.

momo

E wehea hononga matua ki te maha ngā rōpū:

1. Tei runga i te tohu o te nekeneke. Ko te ulungāanga nui tenei. I roto i tenei whakaaro, he he nunui:

• Ko te hononga turanga. I roto i tenei take, he aratohu spigot ranei retireti.
• Tonu pūhui.

2. I roto i te rōpū tuarua whakaaro te he ope e mahi i roto i te taha. E rua ngā momo:

• Kukū. I roto i tenei ope hononga i hanga te i roto i te whakaminenga. vai te reira i wehe i te mahi.
• Unstressed. I roto i tenei ope hononga i hanga te anake, ki te te mahi.

E wehea e te momo o dowels whakamahia 3. pūhui. ara:

• Prismatic.
• Wāhanga.
• Porotakaroa.
• Poro.
• Tangential.

I tua atu tohu ia momo o te matua motuhake. Tuatahi, Heoi, me mea te reira e e te nuinga hanga o-te kounga tiketike, roa Steel Waenga enei wahi: 45, 50, 55. Ko te meka pono tenei. I roto i te tikanga ki te whakapiki ake i te kaha o nga dowels, e te tikanga i raro tutaki mo ratou hanga ki te maimoatanga waiariki. whakapiki i te reira i to ratou kounga.

kī whakarara

Ko o toru nga tu tenei wahi. Kei te wehea e ki kaiarahi, mokete, me te pokarekarenga. Nā ki te meka e ki te keyways whakarara uaua whakakapi ia atu e tika ana ki te urutaunga takitahi, kahore e ratou whakamahia i roto i te hanga nui-tauine. Ko to ratou drawback matua tenei. Ko tētahi atu ngoikoretanga i roto i tenei take ko te kaha ki te hurihia i runga i roto i kākahu.

kī Woodruff

e kore e tenei momo i taua kino rite te tuatahi. Na e ngāwari ki te tono i roto i te hanga ratou. Ko to ratou i te rerekētanga e riro whānuitia ratou whakamahia - te reira i te ripeka-wāhanga nui o te take. Ehara i te mea e taea ki te tāuta ratou i runga i te wahi piko o te take utaina.

kī porotakaroa

Ko tetahi atu momo nui tenei. E whakamahia ratou nuinga i nga pito o te take. Ratou whakamahinga titau e he rerekē i roto i te mātotoru me te pakeke te rauemi ngā. ārai tenei whānui o tenei momo o taviri i roto i te hanga nui-tauine whakamahi.

kī tangential

Kei o rua nga wahi tenei wahi. Tenei ahua o te poro prismatic e he-wāhanga ripeka tapawhā. Whakapumautia takirua matua tangential i te koki o 120-180 nekehanga. Ko te painga o enei wahi ko e mahi ratou rauemi i roto i te kōpeketanga me hoki i konei i reira ko te ahua pai o te haehae hāngai ki te kukū hāngai o taumahatanga. Ko te mate o te kī i taua, ka taea e whakaaro e koe i te reira i te pūrere matatini. Te whakamahi i enei wahi i roto i te mīhini taimaha.

poro matua

A faaite tuku ratou te whakamahi i ope waku.

Pluses o ngā wāhanga i mea:

- hononga patopato i roto i tenei take e taea te te tu te kawenga axial iti.

- He ko he mahi pai i raro i te mana o kawenga tāupe.

- Ehara i te mea e tika ana ki te whakamahi i ngā wāhanga atu e ka mau ki te kaupapa axial o nga ä.

Kangatari o nga mau taviri e whai ake nei:

- Ko te whīwhiwhi o te disassembly i roto i te hanga.

- Kaha wāhikē i te pokapū o te whanaunga hub ki te tuaka take. Ko te meka nui tenei.

- I roto i te aroaro o te roa poto ko reira Kit taea Tipihori nui, me te runout kore wahi waho whakaritea nei (wīra, taputapu).

Ngā tukunga pūhui keyways

Ko te nemaloznachimym tenei whakamāramatanga. Ki te whakarite i te kounga o te tukunga i whakaritea pūhui keyways. He mea nui ki te mohio. Tautuhi patopato GOST 2.308-79 "pūnaha Unified o tuhinga hoahoa. Kia mōhio i roto i te tuhinga momo o te tukunga me te papa ". hāngai ana tēnei ki te turanga pakipūmeka.

Ko te tawhā tau whakaturia ngā tukunga wāhi ki te whakaaro ki nga whanaunga e whai ake nei: T (Pr) = 0.6 T (br); T (sim0) = 4.0 T (w).

Hea ngā enei iku'anga:

- T (br) - kātakí patopato whanui mokamoka b.

- C (te korohū) - ka mea tawhā parallelism.

- T (Sim) - hangarite uara kātakí o te uara diameter.

Ko te tawhā tātai o te raraunga ofi ange ki nga whakamāramatanga paerewa. Arahina hoki tenei ki a GOST 24643.

Whakatō pūhui keyways

Ko te tika o te faatumuraa i wahi whakaratohia mā te tīpako i tenei kōwhiringa. He mea nui ki te whakaaro. Ngā tukunga tautuhi toru ngā momo o pūhui ūnga ranei. Kei te faaterehia te reira e te mau ture. Next, titiro i ia momo o te taipitopito.

pūhui free

Tenei taunga whakamahia i raro i ngā āhuatanga uaua ki te taua hahi kawenga. Whakamahia hoki hononga pūkoro whakaratohia mahi ohipa marama.

hononga noa

Āhuatanga reira hei pai pokanoa, e kore e rapua e ngutungutu auau. āhuatanga rerekē hanga pai.

Junctions kikī

whakaritea ratou te tūponotanga o te fariiraa i interferences iti āhua ōrite i roto i te toko tēnā jointing ki e rua wāhanga (o ratou i'ai). whakamahia te whakaminenga e i roto i te maha iti o kawenga Whakamuri.

Whakatau i o enei pūhui

Ka rite ki kua whakahuatia i runga ake, te arero tino hanga o-te kounga tiketike, me te kaha steels o reo (55, 50, 45). Hei whakanui i te kaha o te wahi pātea hoki e te nuinga o i raro ratou ki wera maimoatanga, e whakapiki i to ratou kounga.

A, no te whakawhanake i te hononga patopato, i mua-tuhi ake, te teitei me te whānui o te wahi te whakamahi i GOST paerewa 2336-7, tango ki pūkete te diameter o te take. I roto i tenei take, kahore he mea uaua. Ko te roa o te arero tango i runga i te hub rānei. Whakatauritea tenei ki te ture paerewa e hāngai ana. Ko te kōwhiringa o etahi tawhā matua tirohia e tono tātai kaha hononga matua nui. I roto i te tātai i tēnei ko kahore mahi nui. Hei tauira, te huru o te kaha i roto i tenei take ko te tātai e whai ake:

σsm = F1 / ACM ≤ [σsm].

Here, F1 - tawhā kaha circumferential ki te wīra (H). Ko AFM te rohe kutikuti (mm²). takoto ana tēnei uara e te tātai e whai ake nei: (0,94h-T1) LP.

I roto i tenei take, LP = l-i roto i te matua, ko te roa mahi ki pito porotaka. whanganga ana tēnei tawhā te i roto i te mitamano. l - patopato te roa tonu.

Uara i roto i, h, T1 he rahi paerewa i roto i runga i te GOST 23360 - 78.

[Σsm] - te whakatakoto i te tiango ngaohiko whakaaetia i runga i (N / mm²). A, no te whakamahi rino Kit [σsm] e riro i roto i te tetahi ngā 55 ... 95 N / mm².

tatau mahi roa matua te e whai ake:

LP = 32 - 6 = 26 mm.

Whakatau i o te rohe kuru:

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

Ko te uara o F1 whakaae ki te inenga whiwhi. I roto i tenei take, F1 = 1200 H.

Ka rite ki te hua, ka hei te tātaitanga o te ngaohiko te tauanga:

σsm = 1200 / 55.64 = 21.56 N / mm².

tohu tenei e te huru o te kaha:

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

Huapai hononga matua

kitea i konei te te whai ake:

• Hoahoa pono, me te roa.
• He ngāwari ki te huihui me te wetewete i ratou.
• utu iti.
• He ngāwari ki te hanga ratou.

hapehape

I roto i te faatura i tenei, kite te whai ake:

• Keyway whakawarea wāhanga o te take, me te hub.
• I roto i te pūhui maha reira he misalignment. Ko, te displacement whanaunga o te tuaka take hub, me te hawhe whakawātea diametrical.
• Ko te koki te taumata ngaohiko keyway tiketike.
