Chishandiso chetsvimbo yekutungamirira uye trapezoids yemotokari

Iwo marevhisi nematanda anowanikwa mushure mebipod yeworm steering mechanism uye rack uye pinion zvinobuda zvinobatanidza zvinogadzira inotungamira dhiraivha system yemavhiri anotungamirwa. Kana makanika ese ari pamusoro payo achingoita basa rekugadzira simba rinodiwa, kutungamira kwaro uye ukuru hwekufamba, ipapo matanda ekutungamirira uye anobatsira marevhera anoumba geometry yevhiri rimwe nerimwe rinotevera gwara rayo. Basa racho harisi nyore, kana tikayeuka kuti mavhiri anofamba pamwe chete nemaarcs avo emadenderedzwa, ayo akasiyana mu radii nehukuru hwemotokari yemotokari. Saizvozvo, makona ekutendeuka anofanira kunge akasiyana, kana zvisina kudaro rubha inotanga kutsvedza, kupera simba, uye mota yese haizopindure zvakakwana kutonga.

Chii chinonzi magetsi ekufambisa?

Iyo rack uye pinion uye worm gears ane akasiyana dhizaini edhiraivha tsvimbo. Muchiitiko chechipiri, itsika kuitumidza kuti trapezoid, uye kune "ndebvu" dzakareruka dzinobuda kubva muchitima, zita pfupi harina kugadzirwa.

Rack uye pinion tie tsvimbo

Kureruka kwenjanji kwakaratidzwawo mukugadzirwa kweiyo traction system. Kunze kwezvombo zvekuzunungusa, izvo zvine hukama zvakanyanya nekumiswa, iyo yese seti ine zvinhu zvina - matanda maviri ane bhora majoini uye maviri ekutungamira matipi, zvakare ekugadzirwa kwebhora, asi zvakasiyana-siyana. Nezve ruzivo rwemunhu, iyo nomenclature yakakura:

• matanda ekutungamirira, kazhinji akafanana kuruboshwe uye kurudyi, anopiwa nemazano e spherical;
• kubva kunze kwemaitiro, hinges yematanda inodzivirirwa nemarara anthers, pamutengo dzimwe nguva unofananidzwa nematanda;
• pakati petsvimbo uye chidimbu pane chigunwe-chinogadzirisa clutch nekiyi yekiyi;
• iyo inotungamira muromo kazhinji isinga patsanurwe, iyo yekurudyi mufananidzo wegirazi weruboshwe, inosanganisira muviri, pini ine sphere, inopinza, chitubu uye rubber boot.

Iyo geometry inobvumira mavhiri kutenderera pamakona akasiyana, sezvatsanangurwa pamusoro apa.

Kutungamira trapezoid worm kana screw gearboxes

Apa ndipo panobva panyanya kuoma zvinhu:

• matanda ekutungamirira anowanzova matatu, kuruboshwe, kurudyi uye pakati, kunewo mamwe maitiro akaoma;
• tsvimbo imwe neimwe inotanga uye inopera nemazano ekutungamirira bhora, uye iyo yakanyanyisa inoitwa collapsible nekuda kwekuvapo kwezvigunwe zvakafanana zvekugadzirisa zvigunwe muchikamu, saka hatigoni kutaura pamusoro pematanda maviri akanyanyisa, asi pamusoro pemazano mana ekutungamirira, dzimwe nguva ivo. anopiwa mune iyi fomu, akakamurwa mukati, kunze, kuruboshwe uye kurudyi;
• chimwezve chinhu chakaunzwa mudhizaini, ichiita trapezoid symmetrical, kubva padivi rakatarisana neiyo longitudinal axis yemuviri kubva pabipod yegiya bhokisi guru, pendulum lever ine bipod yakafanana inoiswa, iyo yepakati uye yakanyanyisa kurovera yakasungirirwa. kwairi.

Iyo trapezium yakafanana yakabatana nemaoko ekuzununguka, yakagadzika yakasungirirwa pazvibhakera zvehub node. Kutenderera kwezvibhakera kunoitwa mumabhora maviri ekumisa.

Majoini ebhora rekutungamirira

Hwaro hwemajoini ese edhiraivha majoini ebhora (SHS), ayo anogona kutenderera maererano neaxis yemunwe uye kutenderera mundege dzese, zvakasimba kuendesa simba chete munzira kwayo.

Mumagadzirirwo ekare, zvishwe zvakaitwa kuti zviputse, izvo zvaireva kugadziridzwa kwavo nekutsiviwa kwenaironi liner. Ipapo iyi pfungwa yakasiiwa, pamwe nekuvapo kwegiresi fittings pachiuno kuti udzore lubricant. Iyo muromo inoonekwa seinodyiwa, iri nyore kutsiva uye isingadhure, saka kugadzirisa kunoonekwa sekusingashande. Panguva imwecheteyo, kuvhiyiwa kwejekiseni yenguva dzose yehinges kwakabviswa kubva pakurongwa kwekugadzirisa. Saka inovimbika zvakanyanya uye yakachengeteka, kutyaira uine hinge yakagadziriswa kuzere nekudimburwa kwekusundira nekumhanya nemhedzisiro ine njodzi.

Iyo yakajairika kesi yekugadzirisa ndeyekugadzirisa dhiraivha nekutsiviwa kwese zvishwe, mushure meiyo sisitimu inogadziridzwa zvizere uye chengetedzo inovimbiswa. Izvo zvinongodiwa kutarisisa kuchengetedzeka kwevhavha yerubha paunenge uchiongorora chassis panguva yekugara uchigadzirisa. Kuora mwoyo kwemazano ebhora pakarepo kunotungamirira kukukundikana kwavo, sezvo mukati mune lubricant iyo inokurumidza kukwezva guruva rinoputika nemvura. Backlash inoonekwa mune matipi, chassis inotanga kugogodza, zvinova nengozi kutyaira mberi.
