Peek inotsiva simbi uye inotanga kushandiswa mumvumo-benz gearbox ges

Yakakwirira-poly plastiki dzakadai sePolyeethethertone (peek) inopa mikana yakawanda inobatsira yekuvandudza gear kugadzirisa. GeEK maGees anoshandiswa kekutanga muMercedes-Benz Gearboxes.

Mass Balancer Gears akagadzirwa neVetsakeep 5000 g ndiyo yekutanga mapurasitiki magiya kuti ishandiswe muMercedes-benz kutapurirana. Inotsiva iyo yaimboshandiswa simbi geya

Magiya epurasitiki ari kutsiva zvishoma nezvishoma masimbi ehutsinye mune dzakawanda zvekushandisa zvekushandisa nekuti ivo vakareruka, vanonyadzisira, vane froria rakaoma, vane zvakapfava, uye vanogona kugadzirwa zvakanaka. Zvigadzirwa zvakagadzirwa zvakakwirira-polycics zvakadai sePolyethetherkettone (peek) zvinowanzoitika zvakamira, zvakarongeka pane maGearing mapuranga uye nekudaro akagonesa mutoro wekutakura anoganhurira. Chinhu chakakosha preerequisite iyi ndeyekuenderana nekuongorora uye yakakodzera chikamu chechimiro cherudzi rwepurasitiki.

In 2018, a Competence Center for Tribology was founded in Darmstadt, Germany, for the development of high-performance plastics for the production of components subject to frictional stress, such as: PEEK, polyamide 12 (PA12) and polyimide (PI ). Pamusoro penzira dzakajairika dzakadai sepini-pane-diski uye bhora-pane-disk bvunzo (kuburikidza ne mini matters), vakaisa mhando yetsiva yebvunzo rig (Fig. 1).

Iko kupfekedzwa uye kupfeka maitiro emagiya kuomarara uye kunoenderana nezvakananga kushushikana mukubatana neine simbi pinion uye mamiriro ekunze panguva yekushanda. Kusvika parizvino, hapana bvunzo yemhando dzakadai sePin-On-disc bvunzo kana musanganiswa wezvetsika uye zvine simba zvekufungidzira zvakakwanisika kuongorora maitiro epurasitiki emagiya mukushanda nekuda kwemamiriro ezvinhu akasarudzika emagiya. Panzvimbo iyoyo, chikamu-chakanangana nehunhu hunhu hwekugadzira zvinogona kutsanangurwa pamapurasitiki maGears muCompoon bvunzo paGear bvunzo rig. DYNAMIC STRICK uye Mechancal Internating mitoro inoiswa kuburikidza nesimbi inotyisidzirwa pinion kune mapurasitiki emeno mazino akanyorwa neTorque mutoro, kumhanyisa uye tembiricha. Mapurasitiki maGears akanyungudika nemafuta kana mafuta etc. anogona kufananidzwa kuti ome kumhanya mapepa epurasitiki.



Muedzo unoitwa maererano neGerman Vdi 2736-4-4- "thermoplastic magiya: Kutsunga kweGear Kubhadhara hunhu") Kuti uzive iyo yekukanda madhiri uye kupfeka zvinoenderana nemutoro wakasiyana. Mhedzisiro iyi inoshandiswa seyakagadzirwa data mune nyanzvi giya gidhi dhizaini simulation zvirongwa zvekubatsira vatengi vanokwanisa kuronga magadzirirwo. Kuedzwa kazhinji kunoenderera kusvikira gear kuchakundikana nekuda kwekupfeka kupfeka kana mazino midzi kupwanya. Tooth Roga tembiricha inokanganisa kusiyana kwemutauro inogona kumira, saka inogona kuyerwa uye kudzorwa ne infrared (IR) sensors pane zviripo muedzo uripo.

Kugonesa michina yezvimiro uye kumakemikari kuramba kwe peek

Paunenge uchikudziridza polymers yakakwirira-perymers yemigadha, izvo zvakanangana nemuchina, zvekupokana uye zvezvematunhu zvinofanirwa kuwirirana zvakanyanya sezvinobvira zvinoenderana nekushushikana kunobatanidzwa. Zvimwe zvekugadzirisa zvinhu zvinogona kukanganisa maitiro egiya. Semuenzaniso, vanowedzera dzimwe nguva vanoshandiswa kuvandudza midziyo yeanti-kupfeka kana kuderedza kupokana nehunhu hwemagetsi ).

Kuenzaniswa neinjiniya mapurasitiki senge polyoxymymylene (POM), PAM uye PA6 uye PALO.CLANCE PLASSILE PLAZI ine zvakawanda zvakanakira kana zvakashandiswa seganda. Kunyanya, kunogona kutamisa zvakare mirefu yakakwirira pakupisa kwakanyanya. Nekuda kwekunyura kwayo kwemvura uye kuderera uye kuderera-shrinkage, zvakaumbwa zvikamu zvakagadziriswa, uye zvichibva pamanyorerwo emidziyo yemidziyo yeTernMplastic, iyo zvakare inodzivirira nemakemikari. Izvi zvivakwa zvinonyanya kukosha kana magiya akaiswa mafuta nemota mafuta kana kutapudza mvura, iyo inzvimbo yakashata yemapurasitiki mazhinji.
