Hukama huripo pakati pekusarudza bhora remuchina weroller chain nekumhanya kwaro

Mumaindasitiri ekutumira zvinhu, kukwira kwecheni yeroller uye kumhanya ndizvo zvinhu zvikuru zvinosarudza kushanda zvakanaka kwekutumira zvinhu, hupenyu hwemichina, uye kugadzikana kwekushanda. Mainjiniya mazhinji nevashandi vekutenga zvinhu, vanonyanya kutarisa kugona kwekutakura zvinhu panguva yekusarudza, vanowanzo kanganwa kuenderana kwezvinhu zviviri izvi. Izvi zvinozopedzisira zvaita kuti cheni iparare uye iparare, uye kunyange nguva yese yekushanda kwemutsetse wekugadzira. Chinyorwa chino chichatsanangura misimboti iri pasi uye hukama huripo pakati pekukwira nekumhanya, zvichipa nzira dzekusarudza dzinoshanda kuti dzikubatsire kusarudza cheni yeroller yakakodzera mamiriro akasiyana ekushanda.

I. Kunzwisisa Pfungwa Mbiri Dzinokosha: Tsananguro uye Kukosha Kweindasitiri kweKukwira Kwenzwi uye Kumhanya

Usati waongorora hukama huripo pakati pezviviri izvi, zvakakosha kujekesa tsananguro huru—izvi zvakakosha kudzivirira zvikanganiso zvekusarudza. Ingave uchishandisa ANSI (American Standard), ISO (International Standard), kana GB (National Standard) roller chains, simba guru repitch nekumhanya rinoramba rakafanana.

1. Kukwira kweRoller Chain: Kunoona "Kukwanisa Kutakura" uye "Kushanda Kwakatsetseka"

Pitch ndiyo core dimension ye roller chain, zvichireva daro riri pakati pepakati pe roller mbiri dziri pedyo (dzinoratidzwa nechiratidzo chekuti "p" uye dzinowanzo kuyerwa mu mm kana inches). Inosarudza zvakananga hunhu huviri hwe key chain:

Kukwanisa Kutakura: Kukwira kukuru kunowanzoita kuti pave nezvinhu zvakakura zvecheni zvakaita semaplate nemapini, uye mutoro wakakwira (wese usingachinji uye unoshanduka) unogona kutakurwa, zvichiita kuti zvikwanise kushandiswa pamabasa anorema (senge michina yekuchera migodhi nemidziyo inorema yekutakura zvinhu).

Kufamba Kwakatsetseka: Kurira kudiki kunoderedza "kumhanya kwemhedzisiro" kana cheni ikabatana ne sprocket, zvichikonzera kudedera kushoma uye ruzha panguva yekutumira. Izvi zvinoita kuti ive yakakodzera kune zvishandiso zvinoda kugadzikana kwakanyanya (senge maturusi emuchina chaiwo uye michina yekurongedza chikafu).

2. Kumhanya Kwekutenderera: Kunoona "Kushushikana Kwakasimba" uye "Kukurumidza Kupfeka"

Kumhanya kwekutenderera pano kunoreva kumhanya kwe sprocket inotyaira iyo cheni yakabatana nayo (inoratidzwa nechiratidzo "n" uye inowanzo kuyerwa mu r/min), kwete kumhanya kwemugumo unotyaira. Kukanganisa kwayo pacheni kunonyanya kuratidzwa muzvikamu zviviri:
Kushushikana kwesimba: Kumhanya kwakakwira, simba re centrifugal rinogadzirwa neketani panguva yekushanda rinowedzerawo "mutoro weimpact" kana cheni ikabatana nemazino e sprocket (zvakafanana nekukanganiswa kwemotokari ichifamba pamusoro pe speed bump nekumhanya kwakanyanya).
Kufamba kwecheni: Kana kumhanya kwacho kwakakwira, ndipo panowedzera kutenderera kwecheni ne sprocket uye kutenderera kwema rollers nema pini. Huwandu hwese hwekupfeka munguva imwe chete hunowedzera zvakaenzana, zvichipfupisa hupenyu hwecheni.

II. Pfungwa Yepfungwa: Nheyo ye "Inverse Matching" yePitch neSpeed

Maindasitiri akawanda akasimbisa kuti kukwira kwe "roller chain pitch" nekumhanya zvine hukama hwakajeka hwe "inverse matching" - ndiko kuti, kumhanya kwakakwira, kukwira kwe "pitch" kunofanira kuva kudiki, nepo kumhanya kwakaderera, kukwira kwe "pitch" kunogona kuva kukuru. Chinangwa chikuru cheiyi nheyo ndechekuenzanisa "zvinodiwa nemutoro" ne "dynamic stress risk." Izvi zvinogona kupatsanurwa kuita zvikamu zvitatu:

1. Kushanda nekukurumidza (kazhinji n > 1500 r/min): Kurira kudiki kwakakosha.
Kana kumhanya kwe sprocket yedhiraivha kuchidarika 1500 r/min (sekunge mumafeni nema small motor drives), simba rekumanikidzwa rinoshanduka uye simba re centrifugal pacheni rinowedzera zvakanyanya. Kushandisa cheni ine pitch yakakura mumamiriro ezvinhu aya kunogona kukonzera matambudziko maviri akakosha:

Kurema kwemutoro weimpact: Maketani makuru ane malink akakura, zvichikonzera nzvimbo yakakura yekubata uye simba reimpact nemazino esprocket panguva yekuisa mesh. Izvi zvinogona kukonzera "link jump" kana "sprocket tooth breakage" nekumhanya kwakanyanya.

Kurembera kunokonzerwa nesimba reCentrifugal: Maketani makuru ane huremu hwakakura, uye simba reCentrifugal rinogadzirwa nekumhanya kwakanyanya rinogona kukonzera kuti cheni ibve pamazino esprocket, zvichikonzera "kudonha kwecheni" kana "kutsvedza kwedhiraivha." Muzviitiko zvakakomba, izvi zvinogona kukonzera kubonderana kwemidziyo. Saka, pakushandisa nekukurumidza, cheni dzine pitch ye12.7mm (1/2 inch) kana pasi dzinowanzo sarudzwa, dzakadai seANSI #40 ne #50 series, kana ISO 08B ne 10B series.

2. Mashandisirwo ekumhanya kwepakati nepakati (kazhinji 500 r/min < n ≤ 1500 r/min): Sarudza kukwirira kwepakati nepakati.
Kushandiswa kwekukurumidza kuri pakati nepakati kunonyanya kushandiswa mumaindasitiri (senge maconveyor, machine tool spindles, uye michina yekurima). Kuenzana pakati pezvinodiwa zvemutoro nezvinodiwa zvekupfava kwakakosha.
Kune zvinhu zvine mwero (sezvinoita ma conveyor light ane simba re10kW kana pasi), cheni dzine pitch ye12.7mm kusvika 19.05mm (1/2 inch kusvika 3/4 inch) dzinokurudzirwa, dzakadai seANSI #60 ne #80 series. Kune zvinhu zvakawanda (senge machine tools epakati nepakati ane simba re10kW-20kW), cheni ine pitch ye19.05mm-25.4mm (3/4-inch kusvika 1-inch), dzakadai seANSI #100 ne #120 series, zvinogona kusarudzwa. Zvisinei, kuongororwa kwekuwedzera kwehupamhi hwezino re sprocket kunodiwa kudzivirira kusagadzikana kwe meshing.

3. Kushanda nekukurumidza zvishoma (kazhinji n ≤ 500 r/min): Cheni huru yekukanda inogona kusarudzwa.

Mumamiriro ezvinhu asinganyanyi kumhanya (sekuchekesa simbi dzekuchera nedzekusimudza zvinhu zvine simba guru), simba remagetsi recheni uye simba repakati pesimbi hazvina kunyanya kusimba. Kukwanisa kutakura zvinhu kunova chinhu chikuru chinodiwa, uye zvakanakira cheni ine simba guru zvinogona kushandiswa zvizere:
Maketani makuru anopa simba guru rezvikamu uye anogona kutsungirira kukuvara kwemazana ekN, zvichidzivirira kutyoka kweplate yeketani uye kukotama kwepini pasi pemitoro inorema.
Kupera kwesimbi kwakaderera kana uchimhanya zvishoma, zvichibvumira cheni dzine maburi makuru kuti dzirambe dzakareba zvinoenderana nehupenyu hwese hwemidziyo, zvichibvisa kudiwa kwekutsiviwa kakawanda (kazhinji makore 2-3). Cheni dzine maburi ≥ 25.4mm (1 inch), dzakadai seANSI #140 ne #160 series, kana cheni dzine maburi makuru dzakagadzirwa, dzinorema, dzinowanzo shandiswa mumamiriro ezvinhu aya.

III. Gwaro Rinoshanda: Enzanisa Kukwira Kwenzwi Nekumhanya Nemazvo muNhanho 4

Mushure mekunzwisisa dzidziso iyi, inguva yekuishandisa kuburikidza nemaitiro akajairwa. Matanho mana anotevera achakubatsira kusarudza nekukurumidza cheni yakakodzera uye kudzivirira zvikanganiso zvinokonzerwa nekuvimba neruzivo:

Danho 1: Ziva MaParameters Makuru - Unganidza Data Remakiyi Matatu Kutanga

Usati wasarudza cheni, unofanirwa kuwana aya matatu ma parameter epakati emuchina; hapana kana chimwe chazvo chinogona kusiiwa:

Kumhanya kwe sprocket yekutyaira (n): Tora izvi zvakananga kubva mubhuku remagineti kana redhiraivha. Kana kumhanya kwekupedzisira kwedhiraivha kuripo chete, verenga uchishandisa fomura inoti “Transmission ratio = nhamba yemeno ari pa sprocket yekutyaira / nhamba yemeno ari pa sprocket yekutyaira.”

Simba rekuchinjisa rakayerwa (P): Iri ndiro simba (mu kW) rinodiwa kuti rifambiswe nemidziyo panguva yekushanda kwayo kwakajairika. Izvi zvinosanganisira zvinhu zvinorema zvakanyanya (zvakadai sezvinhu zvinorema panguva yekutanga, izvo zvinowanzoverengerwa se1.2-1.5 nguva yesimba rakayerwa).
Nzvimbo yekushandira: Tarisa guruva, oiri, tembiricha yepamusoro (>80°C), kana magasi anoparadza. Kana nzvimbo dzakaoma, sarudza cheni dzine magirobhu ekuzora uye machira anodzivirira ngura. Nzvimbo yacho inofanira kuwedzerwa ne10%-20% kuti ikwanise kupfekwa.

Danho rechipiri: Kusarudza Nzvimbo Yekutanga Yekukanda Pitch Zvichienderana Nekumhanya
Tarisa tafura iri pazasi kuti uone huwandu hwepitch yekutanga zvichienderana nekumhanya kwesprocket yedhiraivha (uchishandisa ANSI standard chain semuenzaniso; mimwe mitemo inogona kushandurwa zvinoenderana nazvo):
