Kodi ntchito ya masika ndi chiyani?

Kuphulika kwa masikandi chigawo chophatikizika chomwe chimaphatikiza ntchito za zinthu zotanuka ndi ma bushings mu makina amakina. Amagwiritsidwa ntchito kwambiri pazinthu monga mayamwidwe owopsa, kusungitsa, kuyikika komanso kuchepetsa mikangano. Ntchito zake zazikulu zitha kufotokozedwa mwachidule motere:

1. Mayamwidwe owopsa ndi kusungidwa kwamphamvu
Zitsamba zam'madzi zimayamwa ma vibrate amakaniki ndi mphamvu nthawi yomweyo kudzera mu zotanuka (mongamphira, polyurethane kapena zitsulo masika masika). Mwachitsanzo, pamakina oyimitsa magalimoto amayikidwa pakati pa mkono wowongolera ndi chimango pamakina oyimitsa magalimoto, zomwe zimatha kutsitsa kugwedezeka komwe kumaperekedwa m'thupi ndi mabampu amsewu ndikuwongolera chitonthozo chokwera. Mawonekedwe ake osinthika amatha kusintha kugwedezeka kwapang'onopang'ono kukhala kutentha kwamphamvu ndikuchepetsa chiwopsezo cha resonance system.

2. Chepetsani kukangana ndi kuvala
Monga cholumikizira cha magawo osuntha, masika a masika amachepetsa kugundana kwapakati popatula kulumikizana kwachindunji pakati pa zitsulo. Mwachitsanzo, galimoto shaftbushingamagwiritsa ntchito wosanjikiza wothira mkati kapena zinthu zodzipangira okha (monga PTFE) kuti achepetse kukana kozungulira, ndikuteteza magazini kuti zisavale ndikuwonjezera moyo wa gawolo. M'makina obwerezabwereza, kusungunuka kwake kungathenso kubwezeranso kusokonezeka kwa axial ndikupewa kuvala kwachilendo chifukwa cha kusalinganika bwino.

3. Thandizo ndi kuika
Masamba a Spring amapereka chithandizo chosinthika cha magawo osuntha ndikukhala ndi ntchito zoyika. M'malo olumikizira maloboti amakampani, amatha kupirira katundu wa radial ndikulola kupotoza kwa ngodya zazing'ono, kuwonetsetsa kusuntha kwa mkono wa loboti ndikusunga bata. Kuphatikiza apo, mapangidwe a preload amatha kusintha kusiyana pakati pa zigawo kuti muteteze phokoso kapena kutayika kolondola komwe kumachitika chifukwa cha kumasula.

4. Kuwongolera phokoso
The mkulu damping katundu wa zotanuka zipangizo akhoza kupondereza kufalikira kwa kugwedera phokoso. Mwachitsanzo, kugwiritsa ntchitomatabwa a rabaram'munsi mwa makina apanyumba amatha kuchepetsa phokoso la 10-15 decibels. M'mabokosi a gear, masika akasupe amathanso kutsekereza njira yotumizira mamvekedwe amawu ndikuwongolera magwiridwe antchito a NVH (phokoso, kugwedezeka ndi nkhanza).

5. Kukulitsa moyo wa zida
Kudzera mwatsatanetsatane mayamwidwe mantha, kuchepetsa phokoso ndi kuchepetsa mikangano, masika bushings amachepetsa kwambiri mawotchi kutopa kuwonongeka. Ziwerengero zikuwonetsa kuti m'makina opangira uinjiniya, ma bushings okongoletsedwa amatha kuwonjezera moyo wazinthu zazikulu ndi 30%. Njira yake yolephereka nthawi zambiri imakhala kukalamba kwakuthupi m'malo mwa kuthyoka mwadzidzidzi, komwe ndikosavuta kukonzekereratu.

Kusankha kwazinthu ndi mapangidwe
- Rubber bushing: mtengo wotsika, ntchito yabwino yonyowetsa, koma kukana kutentha kwambiri (nthawi zambiri <100 ℃).
- Polyurethane bushing: kukana mwamphamvu kuvala, koyenera pazambiri zolemetsa, koma kosavuta kuphulika pakutentha kochepa.
- Metal spring bushing: kukana kutentha kwambiri, moyo wautali, womwe umagwiritsidwa ntchito kwambiri m'malo owopsa monga zakuthambo, koma zimafunikira makina opaka mafuta.

Zomwe zimagwiritsidwa ntchito
- Munda wamagalimoto: kuyimitsidwa kwa injini, ndodo yolumikizira kuyimitsidwa.
- Zida zamafakitale: Thandizo la mapaipi a valve, makina osindikizira chida cha nkhungu buffer.
- Zida zolondola: mawonekedwe owoneka bwino papulatifomu, kuyika zida za semiconductor.

Masamba a masika amapeza bwino pakati pa chithandizo chokhazikika ndikusintha kosinthika kudzera pakuphatikiza zimango zotanuka ndi sayansi yazinthu. Mapangidwe ake amayenera kuganizira mozama zamtundu wa katundu (static / dynamic), ma frequency angapo ndi zinthu zachilengedwe. Zomwe zikuchitika m'tsogolomu zitha kukhala zanzeru (monga ma magnetorheological elastomers) ndikusintha modularization kuti zigwirizane ndi zosowa zaukadaulo zovuta.
