Mujaho webhora

Panguva ino ini ndinokurudzira kuti ugadzire chishandiso chiri nyore asi chinoshanda chekirasi yefizikisi. Ichange iri nhangemutange yebhora. Imwe mukana weiyo track dhizaini ndeyekuti inorembera pamadziro pasina kutora nzvimbo yakawanda uye inogara yakagadzirira kuratidza kunze kwechiitiko chemujaho. Mabhora matatu anotanga panguva imwe chete kubva pamapoinzi ari pahurefu hwakafanana. Mota yekufambisa yakanyatsogadzirwa ichatibatsira neizvi. Mabhora achamhanya nenzira nhatu dzakasiyana.

Chigadzirwa chacho chinoratidzika sebhodhi rakarembera pamadziro. Matatu machubhu akajeka anonamirwa kubhodhi, nzira dzinofamba nadzo mabhora. Mutsetse wekutanga ndiwo mupfupi uye une chimiro yendege yakarerekera. Chechipiri chikamu chedenderedzwa. Bhandi rechitatu riri muchimiro chechidimbu che cycloid. Wese munhu anoziva kuti denderedzwa chii, asi havazive kuti rinotaridzika sei uye kuti cycloid inobva kupi. Rega ndikuyeuchidze kuti cycloid icurve inodhonzwa nenzvimbo yakamisikidzwa pamwe nedenderedzwa, ichikunguruka nemutsara wakatwasuka pasina kutsvedza.

Ngatimbofungidzira kuti tinoisa doti jena patai rebhasikoro uye tokumbira mumwe munhu kuti asunda bhasikoro kana kuritasva zvishoma nezvishoma mumutsara wakatwasuka, asi iye zvino tichacherechedza kufamba kwedoti. Nzira yepoindi yakasungirirwa bhazi inotenderedza cycloid. Iwe haufanire kuita iyi kuyedza, nekuti mumufananidzo tinogona kutoona cycloid yakarongwa pamepu uye nzira dzese dzakagadzirirwa kuti mabhora amhanye. Kuti tiite zvakanaka pane yekutanga, isu tichavaka yakapusa lever yekutangisa iyo inova nechokwadi chekuti mabhora matatu atanga zvakaenzana. Nekukweva chitsigiro, mabhora akarova mugwagwa panguva imwe chete.

Kazhinji intuition yedu inotitaurira kuti bhora rinotevera nzira yakananga, kureva, ndege yakarerekera, ichava inokurumidza uye inokunda. Asi hapana fizikisi kana hupenyu huri nyore. Zvionere wega nekuunganidza iyi yekuedza mudziyo. Wokushanda. Zvishandiso. Chidimbu chine rectangular cheplywood chinoyera 600 ne 400 millimeters kana corkboard yehukuru hwakafanana kana isingasviki mamita maviri epachena epurasitiki pombi ine dhayamita yemamirimita gumi, pepa realuminium 10 millimeter gobvu, waya 1 millimita muhupamhi. , mabhora matatu akafanana anofanira kufamba akasununguka mukati memachubhu. Unogona kushandisa mabhora esimbi akatyoka, lead shot, kana mabhora epfuti, zvichienderana nedhayamita yemukati yepombi yako. Tichaturika mudziyo wedu pamadziro uye nekuda kweizvi tinoda zvibatiso zviviri zvekuturika mifananidzo. Iwe unogona kutenga kana kugadzira zvibatiso zvewaya nemaoko ako pachako kubva kwatiri.

zvishandiso. Saw, banga rinopinza, hot glue gun, drill, sheet metal cutter, pliers, penzura, puncher, drill, wood file uye dremel zvinoita kuti basa rive nyore. Base. Pabepa, tichadhirowa nzira nhatu dzekufamba dzakafanotaurwa pachiyero che1: 1 zvinoenderana nedhirowa mutsamba yedu. Yekutanga yakatwasuka. Chikamu chechipiri denderedzwa. Nzira yechitatu ndeye cycloids. Tinozviona mumufananidzo. Iyo chaiyo yekudhirowa kwematinji inoda kudhirowewa pabhesi bhodhi, kuti isu gare gare tizive pekunamira mapaipi anozova maturu emabhora.

Nzira dzebhora. Machubhu epurasitiki anofanira kuve akajeka, unogona kuona mafambiro edu mabhora mavari. Machubhu epurasitiki akachipa uye ari nyore kuwana muchitoro. Tichacheka hurefu hunodiwa hwepombi, angangoita 600 millimeters, tobva tapfupisa zvishoma, zvakakodzera uye kuyedza purojekiti yako.

Track kutanga rutsigiro. Muchivharo chehuni chinoyera 80x140x15 millimeters, chera maburi matatu ane dhayamita yemachubhu. Gomba ratinonamatira nzira yekutanga, i.e. inoratidza kuenzana, inofanira kuchekwa uye kuumbwa sezvakaratidzwa mumufananidzo. Ichokwadi ndechokuti chubhu haikotami pakona yakarurama uye inobata chimiro chendege zvakanyanya sezvinobvira. Iyo chubhu pachayo inochekwawo pakona iyo inoumba. Namadza machubhu akakodzera mumaburi ese ari mubhuroko.

loading muchina. Kubva pane pepa realuminium 1 mm gobvu, tinocheka maviri rectangles ane zviyero, sezvakaratidzwa mumufananidzo. Mune yekutanga neyechipiri, tinochera maburi matatu ane dhayamita ye7 millimeters coaxially nehurongwa hwakafanana semakomba akacherwa mumatanda emapuranga anoumba kutanga kwemakwara. Maburi aya ndiwo achange ari matendere ekutanga emabhora. Dhonza maburi mundiro yechipiri nehupamhi hwemamirimita gumi nemaviri. Namata zvimedu zvidiki zvikaita rectangular zveshizha resimbi kumapendero akanyanyisa eplate yepasi uye kune iwo epamusoro ndiro ine maburi madiki. Ngatitarisei kurongeka kwezvinhu izvi. Iyo 12 x 45 mm ndiro yepakati inofanira kukwana pakati pemahwendefa epamusoro nepasi uye inokwanisa kutsvedza kuvhara nekuvhura maburi. Mahwendefa madiki akanamirwa kuzasi uye mahwendefa epamusoro anozoganhurira kufamba kwepashure kweplate yepakati kuitira kuti ikwanise kufamba kuruboshwe uye kurudyi nekufamba kwerevheti. Tinochera gomba mundiro iyi, inoonekwa mumufananidzo, iyo iyo lever ichaiswa.

lever ruoko. Isu tichaikotamisa kubva kune waya ine dhayamita yemamirimita maviri. Waya inogona kuwanikwa nyore nyore nekucheka kureba kwe2 mm kubva kune waya hanger. Kazhinji tinowana hanger yakadaro pamwe chete nembatya dzakachena kubva pakushambidzika, uye inova sosi yakanakisa yewaya yakatwasuka uye gobvu nekuda kwezvinangwa zvedu. Bend imwe mugumo wewaya pakona yekurudyi pachinhambwe chemamirimita gumi nemashanu. Imwe magumo inogona kuchengetedzwa nekuisa mubato wehuni pairi.

Lever rutsigiro. Yakagadzirwa nebhuroko rinoyera 30x30x35 millimeters kureba. Pakati pechivharo, tinochera gomba remapofu nehupamhi hwema 2 millimeters, umo muromo we lever uchashanda. End. Pakupedzisira, tinofanira kubata mabhora neimwe nzira. Gonye rimwe nerimwe rinopera nekubata. Anodiwa kuti tisatsvage mabhora mukamuri yese mushure mechikamu chimwe nechimwe chemutambo. Isu tichaita kubatwa kubva pa50 mm chidimbu chepombi. Kune rimwe divi, cheka chubhu pakona kuti ugadzire madziro akareba ayo bhora richarova kuti upedze nzira. Kune imwe mugumo wechubhu, cheka slot umo isu tichaisa ndiro yevhavha. Ndiro haitenderi bhora kuti rirege kutonga pane imwe nzvimbo. Kune rumwe rutivi, patinongobudisa ndiro, bhora pacharo richawira mumaoko edu.

Kuisa mudziyo. Mukona yepamusoro yekurudyi yebhodhi, panzvimbo yakatarwa yenzira dzose, namatidza chivharo chedu chemapuranga umo takanamira machubhu kunheyo. Sungai machubhu ne glue inopisa kubhodhi maererano nemitsetse yakadhirowa. Iyo cycloidal nzira iri kure kure kubva pamusoro peiyo slab inotsigirwa neavhareji kureba nemuti wehuni 35 mm kureba.

Namadza mahwendefa egomba kune yekumusoro track inotsigira block kuitira kuti ikwane mumakomba ehuni block pasina kukanganisa. Isu tinoisa chivharo mugomba repakati peplate uye imwe mukati me casing yemuchina wekutanga. Isu tinoisa magumo evhavha mumotokari uye zvino tinogona kutara nzvimbo iyo ngoro inofanira kusungirirwa kubhodhi. Iyo mechanic inofanira kushanda nenzira yekuti kana lever yatendeudzirwa kuruboshwe, maburi ese anozaruka. Maka nzvimbo yakawanikwa nepenzura uye pakupedzisira nama rutsigiro neglue inopisa.

Fun. Isu tinorembera njanji uye panguva imwechete mudziyo wesainzi pamadziro. Mabhora ehuremu hwakafanana uye dhayamita anoiswa panzvimbo dzawo dzekutanga. Tendeukira kuruboshwe uye mabhora anotanga kufamba panguva imwe chete. Isu taifunga here kuti bhora rinomhanya kwazvo patambo yekupedzisa raizove iro riri papfupi 500mm track? Kuziva kwedu kwakatadza isu. Apa hazvina kudaro. Iye ari wechitatu patambo. Zvinoshamisa kuti ichokwadi.

Bhora rinomhanya zvakanyanya nderekuti rinofamba munzira yecycloidal, kunyangwe nzira yaro iri 550 millimeters, uye imwe yacho ndiyo inofamba nechikamu chedenderedzwa. Ko zvamboitika sei kuti paitangira mabhora ese ane sipidhi yakafanana? Kune ese mabhora, iyo yakafanana inogona simba mutsauko yakashandurwa kuita kinetic simba. Sainzi ichatiudza kuti musiyano wenguva dzekupedza unobva kupi.

Anotsanangura maitiro aya emabhora nezvikonzero zvine simba. Mabhora ari pasi pemamwe masimba, anonzi reaction forces, achiita pamabhora kubva kudivi remakwara. Iyo yakachinjika chikamu cheiyo reaction force, paavhareji, yakakura kune cycloid. Izvo zvakare zvinokonzeresa yakakura avhareji yakatwasuka kumhanyisa kwebhora iroro. Icho ichokwadi chesainzi kuti pamacurve ese anobatanidza chero mapoinzi maviri edikita regiravhiti, nguva yekudonha yecycloid ndiyo ipfupi. Unogona kukurukura mubvunzo uyu unonakidza pane chimwe chezvidzidzo zvefizikisi. Zvichida izvi zvichaisa parutivi rimwe remapeji anotyisa.
