Keyed kubatana. Slot kwokubatana - GOST. Tolerances keyways yeimwe

Keyed kubatana - rudzi maviri maonero pokusvika gasketed zvikamu. Zvakakosha. Muchiitiko chino, zvinhu zvaiva nechokuita ebetsero chinhu - kiyi.

zvoupenyu chikumbiro

zvose runako nyore panyaya iyi. Zvinoshanda keyed kubatana kuti jointing mugodhi uye nomusimboti. Kureva, kwakavatadzisa co-kutenderera panguva torque hutachiwana. Uyewo, yeimwe izvi anoshandiswa, kunyange asina zvikuru, kudzivisa kuchinja kuti ndege zvikamu. In zvinotevera isu funga chete nyaya yokutanga.

mhando

kubatanidza Key vanokamurwa muzvikwata akawanda:

1. Zvichienderana mwero mufambo. Izvi zvinokosha noruzhinji. Panyaya iyi, Munokudzwa:

• The chinjwa kubatana. Muchiitiko chino, pane zvishoma nezvishoma mumatope mutungamiriri kana spigot.
• Still akakura.

2. yechipiri boka anoonekwa samba anoita pavanoparidza. Pane mhando mbiri:

• Chezvirikuitika. In ichi kubatana simba iri kunotangira panguva gungano. It ariko aparadzane Batsiranai mabasa.
• Unstressed. In ichi kubatana simba iri vanowanika kana Batsiranai mabasa chete.

3. Compounds dzakaparadzaniswa mhando vakashandisa dowels. zvinoti:

• Prismatic.
• Chidimbu.
• Cylindrical.
• Wedge.
• Tangential.

Uyezve maitiro neimwe mhando kiyi yoga. Chokutanga, zvisinei, zvinofanira kutaurwa kuti zvikamu izvi Anonyanyowanika yakagadzirwa yepamusoro, hunogara Steel Medium: 45, 50, 55 Ichi chinhu chechokwadi chokwadi. Kuti awedzere simba dowels, nembariro kuti gadzira yavo kazhinji pasi chafariz kurapwa. It kunonatsiridza unhu hwavo.

Parallel kiyi

Chikamu ichi ndicho nezvezvikwata matatu. Kuti rakakamurwa vakapofumara, mortgages uye kufambisa. Nokuti kuti kufanana keyways zvakaoma kutsiva mumwe nokuda kwomunhu kwadzakabva, havasi kushandiswa pamwero mukuru kugadzirwa. Ichi drawback yavo huru. Chimwe chinetso hazvisi kukwanisa kufamba pamusoro panguva kusakara.

Woodruff kiyi

Izvi mhando asina payakaipira dzakadai wokutanga. Saka ivo nyore kushandisa mukurima. Asi vane zvakaipira kuti tigove kushandiswa chaizvo - ndiwo muchinjikwa-chikamu chikuru nomubato. Hazvikwanisiki yokugadza navo hwakakungwa chikamu nomubato akatakura.

cylindrical kiyi

Ichi chimwe mhuka inokosha. Ivo anoshandiswa kunyanya panguva kumigumo mugodhi. Kushandiswa yavo inoda kuti zvinhu zvabatanidzwa akasiyana mune arambe achirema neukukutu. Kanoita akasiyana kushandisa kwaiita makiyi pamwero mukuru kugadzirwa.

tangential kiyi

Chikamu ichi une zvikamu zviviri. pamusoro prismatic achikanganisa mhando iyi ine rectangular muchinjikwa-chikamu. Simbisai tangential anokosha maviri panguva necheparutivi pamusoro 120-180 inegumi. Kunakisa zvikamu izvi ndechokuti kwavo zvinhu inoshanda compression nepano pane akanakisisa chimiro pamberi runoenzanirana paburi pamusoro runoenzanirana Kuwanda kunetseka. The Zvakashatira kiyi akadaro, unogona kufunga izvozvo kunzwisisa zano. Shandisa zvikamu izvi muna rinorema michina.

anokosha achikanganisa

Ivo Point zvitange kushandisa frictional mauto.

Pluses pamusoro akati zvikamu:

- keyed kubatana mune iyi angakudzivisai chiduku axial mutoro.

- Paiva basa rakanaka pasi pokudzora shanduka zvinorema.

- Hazvina zvakafanira kushandisa zvimwe zvikamu kuti achabatwa pamusoro axial kwebasa hubs.

Outs zvaungaita ndeinotevera:

- The Kuoma kunzwisisa disassembly panguva kugadziriswa.

- Strong zvaizopedza kubva pakati nomusimboti hama kuti mugodhi akabatana. Uyu chinokosha chokwadi.

- In pamberi pfupi kureba zvinokwanisika Kit nouchapupu skew uye runout dziripowo chikamu iyo wakaiswa (chisimudziso, giya).

Tolerances keyways yeimwe

Tsanangudzo Izvi nemaloznachimym. Kuti ave nechokwadi chokuti chatingatevedzera ushandiswe tolerances keyways yeimwe. Zvakakosha kuziva. Rinotsanangura keyed GOST 2.308-79 "Yakabatana hurongwa zvakagadzirwa mapepa. Ona zviri vanodhirowa siyana pakati tolerances uye hukawanika ". Izvi rinoenderana vhidhiyo chawo.

The kusanganiswa parameters kuisa nzvimbo tolerances panyaya inotevera ukama: T (Zvirevo) = 0,6 T (
); T (sim0) = 4.0 T (w).

Apo mazita aya anosanganisira:

- T (
) - shiviriro keyed slots upamhi b.

- C (chiutsi) - akati parameter parallelism.

- T (SIM) - symmetry kushivirira kukosha dhayamita ukoshi.

The vakaverenga parameters ari umboo pedyo tichienzanisa tsanangudzo. Kutungamirirwa nokuti izvi GOST 24643.

Kudyara keyways yeimwe

Kururama yokuisa zvikamu inopiwa kusarudza pfungwa iyi. Zvakakosha kuti funga. Tolerances kutsanangura mhando nhatu yeimwe kana landings. It hunodzorwa nemitemo. Next, tarira neimwe mhando zvizere.

vakasununguka remubatanidzwa

Izvi kumhara kushandiswa pasi ezvinhu akaoma pamwe chete nemagungano mitoro. Kushandiswa Mobile kwokubatana inopiwa chiedza basa basa.

Muzvarirwo kubatana

Paaiita kuti ive chipingaidzo akakodzera, haatarisiri kakawanda hadzimbotauri. Good akavaka akasiyana ezvinhu.

zvakasimba junctions

Vakatsunga mukana wokugamuchira anenge kufanana zviduku Inenge iri nhengo dowel jointing pamwe zvinoriumba maviri (cheap car insurance dzavo). Gungano inoshandiswa vashomanana Reverse mitoro.

Kutsunga yeimwe izvi

Sezvambotaurwa pamusoro, rurimi chaizvoizvo chakagadzirwa yepamusoro uye simba steels kuti svikiro (55, 50, 45). Kuwedzera simba chikamu amboita kwavari anowanzoshandurwa pasi kuti vakuchidzire kurapwa, izvo kunonatsiridza unhu hwavo.

Kana kuva keyed kubatana, izvo kwerubwinyo rwakagara rwuripo richiswedera kumusoro, kureba uye upamhi chikamu uchishandisa mureza GOST 2336-7, kufungisisa dhayamita yacho mugodhi. Muchiitiko chino, hapana chakaoma. Kureba rurimi kutora zvichienderana nomusimboti. Enzanisa izvi kuMudzidzisi mureza mitemo. Kusarudzwa zvimwe parameters kiyi achiongorora nokushandisa kukarukureta chinokosha kubatana simba. Pakuverenga ichi haisi hombe. Somuenzaniso, mamiriro ezvinhu simba hazvisi zvinotevera payakavakirwa:

σsm = F1 / ACM ≤ [σsm].

Pano, F1 - parameter circumferential simba kuti chisimudziso (H). AFM ndiye fura nzvimbo (mm²). ukoshi Izvi pakutsvaga mutoo: (0,94h-T1) LP.

Muchiitiko chino, LP = L-anokosha ndiwo nokushanda pakureba pamwe woita miromo. parameter ichi unotaurwa millimeters. k - iri keyed zvizere kureba.

Dziri, h, T1 vari mureza hukuru achitevedza GOST 23360 - 78.

[Σsm] - Ndokunyengetererai bvumidzwa voltage kuparara pamusoro (N / mm²). Kana kushandisa simbi Kit [σsm] ari kugamuchirwa mune imwe siyana 55 ... 95 N / mm².

Kushanda chinokosha kureba rinowanikwa sezvinotevera:

LP = 32 - 6 = 26 mm.

Kutsunga unorema nzvimbo:

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

Kukosha F1 kugamuchira vakachiwana kuyerwa. Muchiitiko chino, F1 = 1200 H.

Somugumisiro, dzemaitirwe of yavose sezvavakatarirwa voltage richava:

σsm = 1200 / 55,64 = 21,56 N / mm².

Izvi zvinoratidza kuti mamiriro simba:

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

Advantages anokosha kubatana

Pano inoonekwa zvinotevera:

• Kugadzira yakavimbika uye yakasimba.
• Ndivo nyore kuti vaungane nekukatanura.
• Low mutengo.
• Ndivo nyore kugadzira.

kutadza

Panyaya iyi, ndinoona zvinotevera:

• Keyway vakashaisa Chikamu nomubato uye nomusimboti.
• In yeimwe dzakawanda pane misalignment. Kureva hama misha yose nomusimboti mugodhi akabatana uye diametrical Clearance nehafu.
• Makona keyway yakakwirira voltage pamwero.
