Ulusi ndi chiyani?

Ulusindi: pamwamba pa yamphamvu kapena chulucho, ndi kozungulira liniya mawonekedwe, ndi yeniyeni mtanda gawo la mosalekeza mbali otukukirani.

Ulusiwo umagawidwa mu cylindrical ulusi ndi taper ulusi malinga ndi mawonekedwe a kholo lake;

Malinga ndi udindo wake mu mayi anawagawa kunja ulusi, mkati ulusi, malinga ndi mawonekedwe ake gawo (dzino mtundu) anawagawa makona atatu ulusi, amakona anayi ulusi, trapezoid ulusi, serrated ulusi ndi zina zapadera mawonekedwe ulusi.

Njira yoyezera:

①Kuyeza kwa angle ya ulusi

Ngongole pakati pa ulusi imatchedwanso Kongono ya mano.

Ngongole ya ulusi ikhoza kuyezedwa poyeza mbali ya Ulusi, yomwe ili pakati pa mbali ya ulusi ndi nkhope yoima ya ulusi.

Mano a ulusi amafanana ndi mizere yozungulira mbali zonse za ulusi, ndipo mfundo zotsatsira zimayikidwa ndi mizere yocheperako.

②Kuyeza kwa phula

Phokoso limatanthawuza mtunda wapakati pa mfundo pa ulusi ndi mfundo yofananira pa mano oyandikana nawo. Kuyeza kuyenera kukhala kofanana ndi ulusi wozungulira.

③Kuyeza kwa diameter ya ulusi

Dera lapakati la ulusi ndi mtunda wa mzere wapakati wapakati perpendicular kwa olamulira, ndipo mzere wapakati wapakati ndi mzere wongoganizira.

Ntchito zazikulu za ulusi:

1.kugwirizana makina ndi kukonza

Ulusi ndi mtundu wa chinthu cholumikizira makina, chomwe chimatha kuzindikira kulumikizana ndi kukonza magawo mosavuta komanso mwachangu kudzera mu kulumikizana kwa ulusi. Kulumikizana kwa ulusi komwe kumagwiritsidwa ntchito nthawi zambiri kumakhala ndi mitundu iwiri ya ulusi wamkati ndi ulusi wakunja, ulusi wamkati nthawi zambiri umagwiritsidwa ntchito polumikizana ndi magawo, ndipo ulusi wakunja umagwiritsidwa ntchito polumikizana pakati pa magawo.

2.sinthani chipangizocho

Ulusi ukhoza kugwiritsidwanso ntchito ngati chipangizo chosinthira, mwachitsanzo, mtedza ukhoza kusintha kutalika kwa lever kuti ukwaniritse cholinga chokonzekera kutalika kwa ndodo, kuti ukwaniritse kusintha kolondola pakati pa zigawo za makina.

3. Kusamutsa mphamvu

Ulusiwu ungagwiritsidwenso ntchito ngati chigawo chotumizira mphamvu, monga makina opangira screw drive. Pankhani yopanga makina, zida zomwe zimagwiritsidwa ntchito kwambiri popatsirana ma spiral ndi zida zolumikizira, zida za nyongolotsi ndi mphutsi zoyendetsa, zoyendetsa zowongolera, ndi zina. Zida izi zimasinthira kusuntha kwa mzere kapena kusuntha kwa mzere kukhala kusuntha kozungulira kudzera mu mfundo yogwirira ntchito ya helix. .

4. Kuyeza ndi kulamulira

Ulusi ungagwiritsidwenso ntchito poyeza ndi kuwongolera. Mwachitsanzo, spiral micrometer ndi chipangizo choyezera chomwe nthawi zambiri chimagwiritsidwa ntchito poyeza kutalika, makulidwe, kuya, m'mimba mwake ndi zina zambiri. Kuphatikiza apo, ulusi ukhoza kugwiritsidwanso ntchito kusintha ndikuwongolera momwe makina amagwirira ntchito molondola monga zida zamagetsi ndi zida zowonera.

Mwachidule, ntchito yaikulu ya ulusi ndi m'munda wa kupanga makina, zamagetsi, optics, etc., kukwaniritsa kugwirizana, kusintha, kufala, kuyeza ndi kulamulira ntchito pakati pa zigawo. Kaya m'munda wopanga makina kapena magawo ena, ulusi ndi gawo lofunikira pamakina.
