Iyo flat kiyi kiyi inotsamira pamativi maviri senzvimbo yekushanda, uye torque inofambiswa neextrusion yekiyi uye padivi pekiyi nzira.
Zvinoenderana nekushandiswa kwakasiyana, kiyi yeflat inogona kukamurwa kuita mhando ina: yakajairwa flat kiyi, nhete flat kiyi, yekutungamira kiyi yekutsvedza uye kiyi yekutsvedza.Pakati pavo, iyo yakajairwa flat kiyi uye yakatetepa flat kiyi inoshandiswa kune static yekubatanidza, uye inotungamira flat kiyi inoshandiswa kune ine simba yekubatanidza.
DIN6885 common flat kiyi yakakamurwa kuita flat kiyi yakatenderedza musoro mhando A, flat kiyi square musoro rudzi B, flat kiyi imwe yakatenderera musoro mhando C. Mamiriro makuru ezvimiro zveakajairwa makiyi akafuratira ibhondi hupamhi b, bond urefu h, uye bond kureba L. .
Rudzi rweA: Musoro wakatenderedza, anti-kutenderera, kiyi nzira inogadzirwa neguyo rekupedzisira uye ine chimiro chakafanana negorofu, uye pane mukaha pakati pepamusoro pekiyi uye hubhu.
Type B: musoro wakatsetseka, wakamisikidzwa nema screws, shaft keyway inofanirwa kugadzirwa ne disc milling cutter, uye migumo miviri haina kusimbiswa mushure mekusangana.
Type C: Imwe magumo yakatenderedza uye imwe magumo ikwere, inogadziriswa nekuguma milling cutter, inoshandiswa kubatanidza iyo shaft yekupedzisira uye hub.
Iyo DIN6885 flat kiyi inoreva iyo yeGerman DIN6885 standard, iyo inoenderana neyenyika standard GB/T1096-2003.Chiyero chinotsanangudza akajairwa A-mhando, B-mhando, uye C-mhando flat kiyi ane hupamhi hwe b=2mm-100mm.
Kumaka nzira yeflat kiyi
Nzira yekunyora yekiyi yakafuratirwa ine zita, kiyi fomu, kiyi hupamhi b× kiyi kureba h × kiyi urefu L, DIN6885.
Semuyenzaniso: Type A yakajairika flat kiyi, b = 8, h = 7, L = 25, yakanyorwa se: Flat kiyi A mhando 8×7×25 DIN6885, kana iri B mhando yakajairwa kiyi, saizi yakafanana ne pamusoro, ipapo yakanyorwa se: flat Key B mhando 8×7×25 DIN6885.
DIN6885 flat kiyi dzakagadzirwa nekabhoni simbi uye simbi isina tsvina.Kiyi yakafuratirwa yakapihwa neScrew Street yakagadzirwa nesimbi isina tsvina, yakagadzirwa neSUS304 simbi isina tsvina, ine simba rakawanda uye yakasimba inodzivirira ngura.
Izvo zvinhu zvekiyi yeflat zvine hukama kune zvinhu zve shaft uye zvimwe zvikamu zve rotor.Kazhinji, No. 45 simbi inogona kushandiswa kana pasina ngura, asi munzvimbo ine corrosion, chiitiko uye tsime rekuora kwekiyi yeflat inofanirwa kutariswa, senge liquid For flat keys inosangana neanehasha media, the corrosiveness. zvezvenhau zvinofanirwa kutariswa, uye zvinhu zvinoenderana zvinofanirwa kusarudzwa, kunyanya munzvimbo dzine acidic.Kusarudzwa kwezvinhu zvakakosha zvikuru.Asidhi akasiyana uye maasidhi akasanganiswa ane misiyano mikuru mumidziyo inoenderana, saka kutarisisa kunofanirwa kubhadharwa.
Iyo yekusimba simba reDIN6885 flat kiyi haifanirwe kunge iri pasi pe590MPa.
DIN6885 yakajairwa flat kiyi ine yakanaka kusarerekera, yakakwirira chinzvimbo kurongeka, yakapusa dhizaini uye nyore disassembly uye kusangana, asi haigone kuwana axial fixation yezvikamu pane shaft, uye inoshandiswa kune yakakwira-kumhanya shafts kana shafts inomira zvinokanganisa uye mitoro inoshanduka.
Iyo A-type flat kiyi inoshandisa chigayo kugadzirisa kiyi pashaft.Kiyi inogadziriswa mu groove uye kushushikana kwakanyanyisa.Ndiyo inonyanya kushandiswa uye inowanzo shandiswa mumafasteners muindasitiri yemagetsi.Iyo B-mhando kiyi inoshandisa disc milling cutter kugadzirisa kiyi pane shaft, uye kushushikana kwekushushikana kudiki.Iyo C-mhando kiyi inowanzo shandiswa kune shaft kupera.
Flat kiyi saizi sarudzo: saizi yechikamu b × h yekiyi flat inosarudzwa kubva pachiyero zvinoenderana nedhayamita d ye shaft.Kureba L kwekiyi kunowanzo kutariswa maererano nehupamhi hwehubhu, uye kureba kwekiyi kunodiwa kuve kupfupika zvishoma pane hubhu ne5 ~ 10 mm, uye inowirirana nehurefu hwekutevedza kukosha.
Nyanzvi mukugadzirwa kweDIN6855 makiyi akapfava ane zvirevo zvakakwana uye yakavimbika mhando, unogamuchirwa kubvunza uye kutenga.
