Mitundu 5 Yosiyanasiyana ya Zida ndi Ntchito Zake

Giya ndi gawo lapadera la makina lomwe lingazindikirike ndi mano ake opangidwa mozungulira pamwamba lomwe lili lozungulira, lopanda kanthu, kapena looneka ngati konokono ndipo lili ndi kufalikira kofanana. Zigawo ziwirizi zikalumikizidwa pamodzi, zimagwiritsidwa ntchito munjira yomwe imasamutsa kuzungulira ndi mphamvu kuchokera ku shaft yoyendetsera kupita ku shaft yodziwika. Mbiri yakale ya magiya ndi yakale, ndipo Archimedes amatanthauza kugwiritsidwa ntchito kwawo ku Greece wakale m'zaka za BC.

Tidzakuphunzitsani mitundu 5 yosiyanasiyana ya zida, monga magiya a spur, magiya a bevel, magiya a screw, ndi zina zotero.

 

Zida za Mitre

Izi ndi mitundu yofunikira kwambiri ya magiya a bevel, ndipo chiŵerengero chawo cha liwiro ndi 1. Amatha kusintha njira yotumizira mphamvu popanda kusokoneza liwiro la kutumiza. Akhoza kukhala ndi mawonekedwe a mzere kapena ozungulira. Popeza amapanga mphamvu yoyendetsera mbali ya axial, giya la mitre lozungulira nthawi zambiri limakhala ndi chogwirira cholumikizira. Magiya a mitre angular ndi ofanana ndi magiya a mitre wamba koma ali ndi ma shaft angles omwe si madigiri 90.

 

Zida Zothandizira

Ma shaft ofanana amagwiritsidwa ntchito kupereka mphamvu pogwiritsa ntchito ma spur gear. Mano onse pa seti ya ma spur gear amakhala pamzere wowongoka poyerekeza ndi shaft. Izi zikachitika, ma shaft amapanga radial reaction loads pa shaft koma palibe axial loads.

 

Ma spurs nthawi zambiri amakhala amphamvu kuposa ma helical gear omwe amagwira ntchito ndi mzere umodzi wolumikizana pakati pa mano. Mano ena akakhudzana ndi ukonde, mano enawo amathamanga kupita kwa iwo. Mphamvu imafalikira bwino m'magiya awa pamene mano angapo akukhudzana.

 

Magiya a Spur angagwiritsidwe ntchito pa liwiro lililonse ngati phokoso silikukhudza. Ntchito zosavuta komanso zochepa zimagwiritsa ntchito magiya awa.

 

Zida Zozungulira

Bevel ili ndi malo ozungulira ngati kononi ndipo ili ndi mano oyenda m'mbali mwa kononi. Izi zimagwiritsidwa ntchito kusamutsa mphamvu pakati pa ma shaft awiri mu dongosolo. Amayikidwa m'magulu otsatirawa: ma bevel ozungulira, ma giya ozungulira, ma bevel osapindika; ma bevel owongoka; ndi mitre.

 

Zida za Herringbone

Kugwira ntchito kwa zida za herringbone kungayerekezeredwe ndi kugwira magiya awiri a helical pamodzi. Chifukwa chake, dzina lina la izi ndi zida ziwiri za helical. Chimodzi mwa ubwino wa izi ndikuti zimateteza ku side thrust, mosiyana ndi magiya a helical, omwe amachititsa side thrust. Mtundu uwu wa zida sugwiritsa ntchito mphamvu ya thrust ku ma bearing.

 

Zida Zamkati

Mawilo a pinion awa amalumikizana ndi mawilo akunja ndipo ali ndi mano osema m'masilinda ndi ma cone. Awa amagwiritsidwa ntchito polumikiza magiya. Magiya a Involute ndi trochoid ali ndi magiya osiyanasiyana amkati ndi akunja kuti athetse mavuto ndi kuponderezedwa.
