Keyed mabapi. Sekotjana dikgokelo - GOST. Tolerances keyways metsoako

Keyed mabapi - e mosa ea pono telegraph likarolo tse peli gasketed. Ho ke ke bohlokwa. Tabeng ena, lintho tse amanang le elements ba thusang - senotlolo.

lekala la kopo

bohle ntle e bonolo tabeng ena. Ho hlokehang keyed mabapi bakeng jointing theko le setsi. E leng, ho ba thibela ho sebedisana le manakana a potolohang nakong phetiso torque. Hape, metsoako tsena di a sebelisa, le hoja e se ho pharaletseng, ho thibela ho battlefield tsa likarolo sefofane. Ka seo latelang re nahana feela ka taba ea pele.

mefuta e

mabapi senotlolo ba arotsoe ka lihlopha tse 'maloa:

1. Ho itšetlehile ka tekanyo e sa tsamaiso. Sena ke e bath bohlokoa. Tabeng ena, ke hlaheletseng:

• The mabapi nkehang. Tabeng ena, e le Sliding tataiso kapa beaker.
• Leha ho le joalo komponeng.

2. Ka sehlopha bobeli e nkoa e le matla a eo sebetsang sebakeng sa hae ka kopanelo. Ho na le mefuta e 'meli:

• Tsitsipano. Ka matla ana a mabapi e hlahisoang nakong kopano. E teng ka thoko ho tswa ho workload ena.
• Unstressed. Ka matla ana a mabapi e hlahisoang feela ha workload ena.

3. metsoako ba arohantsoe ke mofuta oa dowels sebediswa. e leng:

• Prismatic.
• Karolo.
• Cylindrical.
• Chesele.
• Bose.

Ho ekelletsa moo khethollang e mong le mofuta oa senotlolo ka thoko. Ntlha ea pele, leha ho le joalo, e lokela ho boleloa hore likarolo tsena tse haholo-holo etsoa ka boleng bo phahameng, tsoarellang Steel Medium: 45, 50, 55. Sena ke ha e le hantle 'nete. E le hore ho eketsa matla a dowels e, mekoallo bakeng proizvodnje bona ba ka kakaretso tlas'a kalafo mogote. Ho ntlafatsa boleng ba bona.

e tšoanang le senotlolo

karolo ena ke ea mefuta e meraro. Hore e arotsoe itsebisa, mortgages le sisinyeha. Ka lebaka la 'nete ea hore keyways tšoanang le thata ho nka sebaka e mong le tse ling tse ka lebaka la ho tloaela sebaka motho, ha ba sebelisoa tlhahiso khōlō. Sena ke drawback bona tse khōlō. mosing 'ngoe tabeng ena ke bokhoni ba ho rōlela fetang nakong qhoaele.

Woodruff senotlolo

mofuta ona ha ba le go tlhoka mesola kang oa pele. Kahoo ba ile ba ba ho le bonolo ho e sebelisa ka tlhahiso. Empa ba na le mosing hore ba fetohe ho pharaletseng sebediswa - e 'se le leholo sefapano karolo ya theko e. Ho ke ke ha khoneha ho kenya bona ka kabelo ea kotlobaneng ea theko laela.

cylindrical senotlolo

Ena ke mefuta e 'ngoe ea bohlokoa. Di sebediswa haholo-holo ho ea lipheletsong tsa theko e. ho sebelisa ha bona ho hloka hore thepa kopantswe tse fapaneng ka segokanyipalo le thatafala. Sena se thibela tšebeliso e sa tšoaneng ea mofuta ona wa linotlolo tlhahiso khōlō.

bose senotlolo

karolo ena e na le likarolo tse peli. Ea mofuta ona e chesele prismatic e nang le likhutlo li 'nè a cross-karolo ya. Theha bose lipara senotlolo sa le hlaha ka lehlakoreng le ya likhato 120-180. Ka ba molemo ho litho tsena ke hore boitsebiso bona sebetsa ka compression le hape mona ho na le mofuta o molemo ka ho fetisisa hara groove lekanang khahlanong le mahloriso e lekanang ya likhatello. The bothata ba ho jwalo senotlolo, o ka ho nka e le sesebelisoa rarahaneng. Sebetsa likarolo tsena ka mechine e boima.

chesele senotlolo

Ba Point a tšoaetsanoang ka ho sebelisa mabotho a frictional.

Pluses tsa likarolo ile a re:

- mabapi keyed tabeng ena a ka mamella e nyenyane axial mojaro.

- Ho na le e ne e le mosebetsi o motle le tlas'a tšusumetso ea mejaro polygonal.

- Ke ho sa hlokahale ho sebelisa likarolo tse eketsehileng tse tla ahlola khahlanong le mokhatlo oa axial tsa hubs ena.

Moseho oa linotlolo ke tse latelang:

- The rarahana ha disassembly nakong lokisa.

- Matla koala ho tloha bohareng ba setsi ka ho tshwana le theko a selekane. Sena ke 'nete ea bohlokoa.

- In ho ba teng ha bolelele lekgutshwanyane hoa khoneha Kit mohlomong skew le runout sa thoko karolo eo e tsitsitseng (pulley, Gear).

Tolerances keyways metsoako

tlhaloso ena ke nemaloznachimym. Ho etsa bonnete ba boleng ba tolerances balletsweng keyways metsoako. Ho bohlokoa ho tseba. E hlalosa keyed GOST 2.308-79 "tsamaiso momahaneng tsa ditokomane moralo. Hlokomela ka litšoantšo mefuta e meng ea tolerances le bokaholimo ". Sena se lumellana le videong botlaaseng.

The entsprechen tlhamiwe beha sebakeng tolerances mabapi le likamano tse latelang: T (PR) = tse 0.6 T (! Br); T (sim0) = 4.0 T (w Le).

Moo litlotla tsena li kenyeletsa:

- T (! Br) - mamello keyed sekotjana bophara b.

- C (mouoane) - itse paramethara parallelism.

- T (SIM) - setshwani mamello boleng ba boleng le bophara ba.

The entsprechen balwa ya data e haufi le litlhaloso e tloaelehileng. Tataisoang bakeng sa ho GOST 24643.

Lema metsoako keyways

Ho nepahala ha ho likolohisa likarolo faneng ka khetha kgetho ena. Ke habohlokoa ho nahana ka. Tolerances hlalosa mefuta e meraro ea metsoako kapa landings. E laoloa ke melao-motheo ea. Ka mor'a moo, sheba mong le mofuta oa ho qaqileng.

mahala komponeng

lulisa ena sebediswa tlas'a maemo a thata le tšoanang likopano tsa mejaro. Sebediswa bakeng sa dikgokelo selefouno feela khanya mosebetsi mosebetsi.

mabapi tloaelehile

Tšoauoa e le ho tshitsiso loketse, ha a hloke squabbles khafetsa. Ntle u ahele maemo a fapaneng.

junctions thata

Ba ikemiselitse kgonego ya fumana hoo e ka bang le tsoanang interferences nyenyane ka dowel fapaneng jointing le dikarolo tse peli (beetsweng bona). phutheho e sebediswa ka palo e fokolang ea mejaro etsolla.

Boikemisetso ba metsoako tsena

Joalokaha ho se ho boletsoe ka holimo, leleme le hantle a entsoe ka steels boleng bo phahameng le matla a mahareng (55, 50, 45). Ho eketsa matla a ea karolo letho bakeng sa bona a atisa ho tlas'a ho futhumatsa kalafo, eo ntlafatsa boleng ba bona.

Ha ba le mabapi keyed, eo pele ho atamela ho fihlela, le bophahamo le bophara karolo e sebelisa molao-motheo GOST 2336-7, nahane ka bophara tsa theko e. Tabeng ena, ha ho letho ho le thata. Bolelele ea leleme nka ho itšetlehile ka setsi sa. Bapisa sena le melao ea tsamaiso tekanyetso tshwaneleha. Tlhopho ya itseng entsprechen senotlolo hlahloba ka ho sebelisa manolotsoeng bohlokoa senotlolo mabapi matla. Ha ho baloa ena ho na u sebetsane khōlō. Ka mohlala, boemo ba matla tabeng ena ke moralo tse latelang:

σsm = f1 / ACM ≤ [σsm].

Mona, f1 - paramethara circumferential lebotho la ho pulley (H). AFM ke sebakeng kuta (mm²). boleng ena e laolwang ke moralo tse latelang: (0,94h-T1) gumanthong.

Tabeng ena, LP = k-in ea bohlokoa ke bolelele sebetsa le lipheletsong lekaneng. paramethara ena e lekanngoa ka millimeters. k - e keyed bolelele feletseng.

Maemo a, H, T1 tse boholo bo tekanyetso ho latela GOST 23360 - 78.

[Σsm] - behela lumeletsoe gagamalo putlama ka (N / mm²). Ha u sebelisa tšepe Kit [σsm] e fumaneng ka ho mefuta e fapaneng itseng 55 ... 95 N / mm².

Sebetsa bolelele senotlolo e balwa ka tsela e latelang:

gumanthong = 32 - 6 = 26 limilimithara.

Boikemisetso ba sithabetsa sebakeng:

ACM = (0.94 · 6 - 3,5) · 26 = 55,64 mm².

Boleng ba f1 amohela litekanyo fumana. Tabeng ena, f1 = 1200 H.

Ka lebaka leo, le manolotsoeng tsa gagamalo rated e tla ba:

σsm = 1200 / 55,64 = 21,56 N / mm².

Sena se bontša hore boemo ba matla:

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

Menyetla mabapi senotlolo

Mona e bone ho latelang:

• Meralo e ka tšeptjoang le tsoarellang.
• Ba ho le bonolo ho bokana le ho qhaqholla.
• Varaa.
• Ba bonolo ho proizvodnje.

mefokolo

Ka tsela ena, lemoha lintho tse latelang:

• Keyway fokola karolo ya theko le setsi sa.
• Ka metsoako tse ngata ha ho lule hantle ha lesapo. Ke hore, displacement a lekanyelitsoeng ea selekane setsi theko le halofo diametrical rengwa.
• Likhutlong keyway phahameng gagamalo boemong ba.
