Maitiro ekudzora mota kumhanya nemapuru

Mapulleys, ayo ari chikamu chemhando yehubhu, kazhinji ane hukuru hukuru hwehukama. Iyo nzira yekugadzira inowanzoenderana nekukanda uye kuforoma. Maitiro ekudzikisa mota kumhanya nemapulleys. (Iyo yakajairika saizi dhizaini inogadzirwa nekukandira. Zvishandiso zvacho zvinowanzo kukanda simbi (yakanaka kukanda kuita), yakanyanya Ishoma yakakandwa simbi (simbi yekukanda kuita haina kunaka); uye kazhinji diki saizi, inogona kugadzirwa kuforoma, iyo simbi isimbi. ) Mapulley anonyanya kushandiswa kutapurirana magetsi ari kure, sekubuda kweinjini diki dzedhiziri, mota dzekurima, matirakita, mota, muchina wemigodhi, michina yekugadzira, machira emuchina, ekurongedza muchina, lathes, mibhedha yekufogisa, mamwe madiki midhudhudhu. Kuendesa, kutapurirana kwemagetsi emagetsi emagetsi, mhepo compressors, zvinoderedza, zvinoderedza, jenareta, gins, etc. Zvakakosha kuziva kuti kuchenesa kwekupedzisira pamberi pekusangana kwepulley kunofanira kushandisa peturu kuona kuti zvikamu zvakachena uye zvakaoma kuti zvive nechokwadi chokuti nzvimbo yekubatanidza yakamanikana uye haina mafuta, ine friction yakakwana.

Maitiro ekudzikisa mota kumhanya nemapulleys. Kumhanya kwemota kunowedzerwa nedhayamita yemota pulley, yakakamurwa nedhayamita yemuchina pulley, yakaenzana nekumhanya kwemuchina.

Zvakanakira mota pulley drive
1. Iyo pulley drive inogona kudzikisira kukanganiswa kwemutoro;
2. Iyo pulley drive inomhanya zvakanaka, ine ruzha rwakaderera uye yakaderera vibration; chimiro chepulley drive chiri nyore uye chiri nyore kugadzirisa;
3, iyo pulley drive yekugadzira uye yekumisikidza chokwadi chepulley haina kuomarara senge mesh drive;
4, iyo pulley drive ine basa rekudzivirira kuwandisa;
5. Kugadziriswa kwemaitiro maviri-axis centre kureba kwepulley drive yakakura.

1 kusarudza musimboti
Maitiro ekudzikisa mota kumhanya nemapulleys. Kusarudzwa kwezviratidzo zvakasiyana-siyana uye zvinhu zvepulley inobva pamutemo wekuti zvinhu zvakasvibirira zvinogona kuderedzwa, nzira yacho inogoneka, uye mari ndiyo yakaderera.

2 kutapurirana zvakanakira

Zvakanakira iyo pulley drive ndeiyi: iyo pulley drive inogona kudzikisira kukanganiswa kwemutoro;Maitiro ekudzikisa mota kumhanya nemapulleys. iyo pulley drive inomhanya zvakanaka, yakaderera ruzha uye yakaderera vibration; iyo pulley drive ine chimiro chakareruka uye nyore kugadzirisa; iyo pulley drive ine yakasimba kugadzira uye kuisirwa iko kurongeka kwepulley; iyo pulley drive Iine basa rekudzivirira zvakanyanya; iyo maviri-axis yepakati kuremerwa kureba kweiyo pulley drive yakakura.Maitiro ekudzikisa mota kumhanya nemapulleys.  Izvo zvisingabatsiri zvebhanhire dhiraivha ndezvekuti: iyo pulley drive ine elastic sliding uye inotsvedza, iyo yekufambisa inoshanda yakaderera uye yakaringana yekufambisa chiyero haigone kuchengetedzwa; apo iyo pulley inotumira iyo yakafanana yakakura circumferential simba, saizi ye contour uye on-shaft pressure yakakura kupfuura meshing transmission; Maitiro ekudzikisa mota kumhanya nemapulleys. iyo pulley drive bhandi Hupenyu hupfupi.

Iwo madhayamita emapulleys emarudzi ese emidziyo yemuchina zvese zvinoenderana nereshiyo yekudzikisa, uye akagadzirwa zvinoenderana nekumhanya kwekushanda uye kumhanya kwemota. Kushanda kumhanya / mota kumhanya = dhiraivha vhiri dhayamita / inotyairwa vhiri dhayamita * 0.98 (inotsvedza coefficient), sekushandiswa kwesimbi sechinhu chepulley, iyo inodiwa mutsara kumhanya haina kukwira kupfuura 40m / s, sekushandisa simbi yakakandwa zvinhu, iyo inodiwa mutsara kumhanya haina kukwira kupfuura 35m / s, mota kumhanya uye pulley dhayamita yekushandura reshiyo, kumhanya ratio = yekubuda kumhanya: yekupinza kumhanya = mutoro pulley pitch dhayamita: mota pulley pitch dhayamita. Kuwanda kwedenderedzwa repitch kwakafanana nedhayamita yedenderedzwa rereferensi. Iyo dhayamita ndeye -2h = the pitch diameter. h ndiko kudzika kwegorofu pamutsara wereferensi.

Maitiro ekudzikisa mota kumhanya nemapulleys. Iyo V-bhendi h yemhando dzakasiyana dzakasiyana. YZABCDE, kudzika kwegorofu pamutsetse wereferensi h=1.622. 753.54.88.19.6. Iyo dhayamita yepulley pitch denderedzwa ndeye theoretical dhayamita yeiyo pulley pitch line chinzvimbo, iyo yakati wandei senge indexing denderedzwa dhayamita yegiya. Iyo inowanzo ratidzwa nePD, uye denderedzwa rekunze rinowanzo miririrwa neOD. Yakasiyana groove mhando pitch madenderedzwa haana kufanana neyekunze denderedzwa rekushandura formula. Maitiro ekudzikisa mota kumhanya nemapulleys. Kazhinji, isu Zviri nyore kuyera denderedzwa rekunze repulley, uye kuverenga denderedzwa repitch maererano neformula. SPZ: OD = PD + 4; SPA: OD = PD + 5.5; SPB: OD = PD + 7; SPC: OD = PD + 9.6. Iyo shoma yekunze dhayamita yepulley yeA kana SPA ndeye 80mm. Kana iri diki pane saizi iyi, kunyanya kana iri kukurumidza kukurumidza, bhandi rinowanzoita delamination uye kuputika pasi.Maitiro ekudzikisa mota kumhanya nemapulleys. SPZ bhandi, vhiri duku anogona kuva asingasviki 63mm. Panguva imwecheteyo, teerera kune nzira uye kukakavara kwekuiswa kwebhanhire. Kana iri diki, inotsvedza nyore nyore. Kana yakakura, inokuvadza bhandi uye kutakura.

3 kugadzirwa zvinodiwa
1. Zvinhu zvinoshandiswa pamhepo inofefetera igrey cast iron HT200, HT250, zvichingodaro.Maitiro ekudzikisa mota kumhanya nemapulleys. (asi zvikamu zvesimbi, zvikamu zvemhangura, zvikamu zvealuminium, nezvimwewo zvinogonawo kushandiswa maererano nezvinodiwa nevatengi).

2. Iyo pulley inofanira kusangana: uremu huremu, yunifomu yakawanda kugovera, kubvisa kushushikana kwemukati kunogadzirwa panguva yekugadzira, uye pulley inofanira kugadziriswa statically.

4 bhandi tsanangudzo
Zvinyorwa zveV-bhandi zvakakamurwa nehupamhi hwemashure (pamusoro pehupamhi) uye kureba (ukobvu).Maitiro ekudzikisa mota kumhanya nemapulleys. Zvinoenderana nehupamhi hwemashure hwakasiyana (hupamhi hwepamusoro) uye urefu (ukobvu), chiyero chenyika chinotsanangura O, A yebhandi reV. , B, C, D, E uye mamwe maenzanisi, imwe neimwe yemhando yeV-belt ine hupamhi hwakasiyana, hupamhi hwepamusoro uye urefu, saka pulley inofanirawo kuitwa maererano nechimiro cheV-belt; Mhando ye groove inosarudza marudzi akasiyana-siyana emapulleys akadai seO-belt pulley, A-belt pulley, B-belt pulley, C-belt pulley, D-belt pulley uye E-belt pulley.
