Parallel Key with Groove, Cartbon Steel, Stainless Steel

Chinsinsi chathyathyathya ndi fungulo lomwe limadalira mbali ziwiri monga malo ogwirira ntchito, ndipo torque imafalitsidwa ndi extrusion ya fungulo ndi mbali ya keyway.

Malinga ndi ntchito zosiyanasiyana, fungulo lathyathyathya litha kugawidwa m'mitundu inayi: kiyi wamba wamba, kiyi yopyapyala, kiyi yowongolera ndi kiyi yolowera.Pakati pawo, kiyi wamba wamba ndi kiyi yopyapyala imagwiritsidwa ntchito polumikizana ndi ma static, ndipo kiyi yowongolera imagwiritsidwa ntchito polumikizana mwamphamvu.

DIN6885 wamba fungulo lathyathyathya amagawidwa kukhala lathyathyathya fungulo lozungulira mutu A, lathyathyathya kiyi lalikulu lalikulu mutu mtundu B, lathyathyathya makiyi umodzi wozungulira mutu mtundu C. Miyeso yaikulu ya makiyi wamba lathyathyathya ndi m'lifupi mwake b, chomangira kutalika h, ndi chomangira kutalika L. .
Mtundu A: Mutu wozungulira, wotsutsa-kuzungulira, njira yachinsinsi imapangidwa ndi mphero yomaliza ndipo imakhala ndi mawonekedwe ofanana ndi groove, ndipo pali kusiyana pakati pa pamwamba pa keytop ndi hub.

Mtundu B: mutu wathyathyathya, wokhazikika ndi zomangira, fungulo la shaft liyenera kupangidwa ndi chodulira mphero, ndipo mbali ziwirizo sizimangika pambuyo pa msonkhano.

Mtundu C: Mapeto amodzi ndi ozungulira ndipo enawo ndi apakati, opangidwa ndi chodula mphero, chomwe chimagwiritsidwa ntchito kulumikiza kumapeto kwa shaft ndi likulu.

The DIN6885 lathyathyathya kiyi amatanthauza German DIN6885 muyezo, amene n'zogwirizana ndi dziko muyezo GB/T1096-2003.Muyezowu umatchula makiyi wamba amtundu wa A, mtundu wa B, ndi C wokhala ndi m'lifupi mwake b=2mm-100mm.

Njira yolembera makiyi a flat key
Njira yolembera ya fungulo lathyathyathya imakhala ndi dzina, mawonekedwe achinsinsi, fungulo m'lifupi b× fungulo kutalika h × fungulo kutalika L, DIN6885.

Mwachitsanzo: Lembani A kiyi wamba wamba, b = 8, h = 7, L = 25, yolembedwa kuti: Chinsinsi cha Flat A mtundu 8 × 7 × 25 DIN6885, ngati ndi B mtundu wa B makiyi wamba wamba, kukula kwake ndi kofanana ndi pamwamba, ndiye chizindikiro monga: lathyathyathya Chinsinsi B mtundu 8×7×25 DIN6885.

DIN6885 makiyi lathyathyathya amapangidwa ndi chitsulo cha carbon ndi chitsulo chosapanga dzimbiri.Kiyi yathyathyathya yoperekedwa ndi Screw Street imapangidwa ndi chitsulo chosapanga dzimbiri, chopangidwa ndi SUS304 chitsulo chosapanga dzimbiri, chokhala ndi mphamvu zambiri komanso kukana dzimbiri.

Zinthu za fungulo lathyathyathya zimagwirizana ndi zinthu za shaft ndi mbali zina za rotor.Nthawi zambiri, No. 45 chitsulo chingagwiritsidwe ntchito ngati palibe dzimbiri, koma m'malo owononga, nthawi ndi gwero la dzimbiri la fungulo lathyathyathya liyenera kuganiziridwa, monga madzi Kwa makiyi athyathyathya okhudzana ndi media aukali, kuwononga. atolankhani ayenera kuganiziridwa, ndi zipangizo zogwirizana ayenera kusankhidwa, makamaka m'madera acidic.Kusankhidwa kwa zipangizo ndizofunikira kwambiri.Ma asidi osiyanasiyana ndi ma asidi osakanikirana amakhala ndi kusiyana kwakukulu muzinthu zofananira, kotero chidwi chiyenera kulipidwa.

Mphamvu yolimba ya DIN6885 fungulo lathyathyathya sayenera kuchepera 590MPa.

DIN6885 wamba lathyathyathya kiyi ali ndi ndale zabwino, mkulu udindo kulondola, dongosolo losavuta ndi disassembly zosavuta ndi msonkhano, koma sangathe kukwaniritsa axial fixation wa mbali pa kutsinde, ndipo amagwiritsidwa ntchito nthiti mkulu-liwiro kapena shafts amene kupirira mphamvu ndi katundu osiyanasiyana.

Makiyi amtundu wa A-amagwiritsa ntchito mphero kukonza njira yolowera pa shaft.Mfungulo imakhazikika mu groove ndipo kupsinjika kumakhala kokhazikika.Ndiwogwiritsidwa ntchito kwambiri ndipo nthawi zambiri amagwiritsidwa ntchito popanga zomangira pamakina opanga makina.Kiyi yamtundu wa B imagwiritsa ntchito chodulira mphero kuti ikonze njira yolowera patsinde, ndipo kupsinjika kumakhala kochepa.Kiyi yamtundu wa C nthawi zambiri imagwiritsidwa ntchito kumapeto kwa shaft.

Kusankha kwa makiyi a Flat: kukula kwa gawo b × h la fungulo lathyathyathya limasankhidwa kuchokera mulingo molingana ndi mainchesi d a shaft.Utali wa L wa kiyi nthawi zambiri umatsimikiziridwa molingana ndi m'lifupi mwake, ndipo kutalika kwa fungulo kumafunika kukhala kofupikitsa pang'ono kuposa 5 ~ 10 mm, ndipo kumagwirizana ndi kutalika kwa mndandanda.

Okhazikika pakupanga makiyi athyathyathya a DIN6855 okhala ndi mawonekedwe athunthu komanso mtundu wodalirika, talandiridwa kuti mukambirane ndikugula.
