The zida mphutsi. Mfundo ntchito

zida mbozi otembenuka zoyenda pa maziko a aŵiri wachiwiri kapena anapambutsa ndege. kusiyana A wapangidwa yaitali ndi diameters koyamba zonenepa. Pole chinkhoswe ndi koyamba kukhudza mfundo yamphamvu kwambiri.

zida mbozi chikuphatikizapo wononga (wotchedwa nyongolotsi) ndipo gudumu. Njingayo mating migodi wononga ndi mawilo angakhale osiyana. Komabe, nthawi zambiri ndi madigiri nainte. zida mbozi ali ndi mwayi pa pachithandara ndi wononga. Zikuoneka kuti poyamba kukhudzana mayunitsi ikuchitika osati pa mfundo koma ndi mzere. Gudumu felemu womwenso zida nyongolotsi, ali mawonekedwe concave. wononga ulusi akhoza lamanja kapena lamanzere, osakwatiwa-chiphaso kapena Mipikisano chiyambi.

Nyongolotsi kusiyana ndi mawonekedwe pamwamba, mmene ulusi aumbike. Monga pali cylindrical ndi globoid mogwirizana. Popeza mawonekedwe a mbiri ya amadziŵika yokhota kumapeto ndipo molunjika masitaelo. Mphutsi ambiri amaonedwa kukhala cylindrical. M'madera ndi mbiri molunjika mu gawo mtanda popereka ankasinthana wa mwauzimu Archimedean. Choncho, iwo amatchedwa Archimedean mphutsi. Iwo amafanana ndi wononga kutsogolera ndi trapezoidal ulusi. Iwo akhoza kudula mu aliyense rezbofrezernom ochiritsira lathe.

Khalani zasonyeza kuti zida galimoto nyongolotsi amatha mkulu ntchito, anapereka kuwonjezeka kuuma ulusi. M'zaka zaposachedwapa, mochulukirachulukira mkulu mbali zovuta pansi. Pakuti processing wa mankhwala ntchito yapadera mawilo umapezeka ndi mbiri mphako. Komabe, n'zovuta pokonza ndi Sachita molondola opangira. Pa nkhani imeneyi, zotsimikizira windings Archimedean nyongolotsi ikuchitika ndi sanali pansi. Pakuti zinthu kwambiri okhwima kukonzedwa ntchito mbali involute ndi ziwalo mbiri nkhope gawo. The mwayi waukulu mphutsi awa ndi kuthekera kuchita umapezeka ankasinthana ntchito m'mbali mwa bwalo. Koma nthawi yomweyo pamafunika makina wapadera.

NMRV helical gearbox ndi mota wapadera. Ubwino wa tsatanetsatane mu kukula yaying'ono, otsika phokoso ndipo uyende. Chifukwa cha yovomerezeka ogwiritsa miyeso angagwiritsidwe ntchito m'malo kuchepetsa wa mayunitsi zida kuchokera opanga ena. Chifukwa kukodzedwa pansi pa mwachindunji ngodya linanena bungwe kutsinde dongosolo ndi thupi chilengedwe penapake modernized, item akhoza adzaikidwa mu malo lachitsanzo ndi coaxial kutsinde sakhoza kukhazikika. Zikomo masiku ano jekeseni akamaumba zipangizo zatsopano mayunitsi chitsanzo chopangidwa lero.

Gudumu nyongolotsi Kadulidwa cutters kake. Amachita zomangira zofanana. Komabe, wodula kukhala ndi m'mimba mwake kunja, ndi kudula m'mbali kwa kukula awiri wamkulu kuposa chilolezo zozungulira. Pamene kudula workpiece ndi wodula gudumu zoyenda wachibale amachitidwa pa mfundo imene zida mbozi.
