Kuphepha kucala
- Cima uphindze uvale i-motor ku-isolator, bhala i-tag, bese uzama kuyicalisa kute uciniseke kutsi ayisebenti.
- Khulula emandla lagciniwe: yekela ema-flywheel nema-fan ame; vimbela konkhe lokungajikeleta ngenca yesisindvo, umoya (ema-fan) nobe i-pressure (ema-pump); khulula ema-tensioner e-pneumatic nobe e-spring.
- Khipha i-guard kuphela emvakwekucima. Yigcine eceleni kwemshini.
Ungazeuhlole kucina, ulalele umsindvo nobe "utive" ema-belt i-drive isasebenta, futsi ungaze usebentise i-drive ngaphandle kwe-guard.
Kukhipha ema-belt lamadzala
- Khulula i-base ye-motor nobe i-tensioner kuze ema-belt aphume ngesandla. Ungaze ukhiphe (nobe ufake) ema-belt nge-screwdriver nobe ngensimbi: kuphula imicu futsi kuchuma i-pulley.
- Ngaphambi kwekuwalahla, buka ema-belt lamadzala: indlela lagugile ngayo ikutjela kutsi bekunani lokungasiko. Buka kulungisa tinkinga.
- Shintja onkhe ema-belt ku-drive lenema-belt lamanyenti kanyekanye. Ema-belt lamadzala anwebekile; i-belt lensha ku-set lendzala itfwala umtfwalo lomkhulu bese iphuka masinyane.
Hlola ema-pulley
- Kugugeka kwema-groove: sebentisa i-groove gauge ye-sekhishini. Phansi kwe-groove lokucwebezelako, i-belt lehamba phansi, nobe emabondza lagobile (kukhanya kuyabonakala emkhatsini we-gauge nelibondza) kusho kutsi i-pulley kufanele ishintjwe. Ema-belt lamasha kuma-groove lagugile aphila sikhatsi lesincane kakhulu.
- Kulimala: ema-flange lachumekile, kuciteka, ema-burr nobe kugwala emabondzeni e-groove.
- Kungena ku-shaft: tikulufo te-taper bush nge-torque lefanele, i-key ikhona, akukho kunyakata.
- Hlanza ema-groove ekugwala, emafutsa nelutfuli lwe-rubber ngendvwangu leyomile nobe i-wire brush. Ungasebentisi ema-solvent lashiya lucwecwe.
Lokunyenti: kugugeka kwema-pulley nekuhlola nge-gauge.
Kufaka ema-belt lamasha
- Hlola ema-belt: sekhishini nebudze lokufanele, kusuka ku-set yinye lefananako (ikhodi yinye nobe entelwe kufanana).
- Sondzetisa i-motor kuze ema-belt angene kuma-groove ngesandla, onkhe ema-belt ngelicala linye (kukhululeka ngelicala linye).
- Susa kukhululeka ngalokulinganako. Gcina i-motor ilungile: shintja ema-jack-screw omabili ngalokulinganako.
- Linganisa (sigaba lesilandzelako), bese uyacinisa.
Kulinganisa
Kunetindlela letintsatfu i-drive lengahle ingalingani ngato:
| Luhlobo | Kuyini | Kubonakala njani |
|---|---|---|
| Parallel (offset) | Ema-shaft ayalingana kodvwa ema-pulley akekho endzaweni yinye. | I-straight edge itsintsa buso be-pulley yinye kodvwa hhayi lenye kuto tonkhe tindzawo. |
| Angular (horizontal) | Ema-shaft akalingani nawubuka phetulu. | I-straight edge itsintsa emaphoyinti lamabili langekho endzaweni yinye; kuvuleka sikhala ngalokunye. |
| Twist (vertical angular) | Ema-shaft akalingani nawubuka eceleni: kuvame kuba ngu-soft foot nobe i-base lengalingani. | I-straight edge nobe umugca we-laser ugobile ebusweni be-pulley. |
Imikhawulo (sicondziso semkhakha)Ema-V-belt nema-wedge belt: kungalingani konkhe kungengci cishe ½°. Ema-timing, ema-poly-V nema-urethane belt: kungengci cishe ¼°. Hlanganisa kungalingani kwe-angular nekwe-parallel: kuhlehla kwa-x mm ku-centre distance ya-C mm yi-angle ye-atan(x/C). ½° icishe ibe ngu-8.7 mm emitheni ngayinye; ¼° cishe 4.4 mm emitheni. Labanye labenta ema-belt babeka imikhawulo lelukhuni kulamanye ema-belt.
Emathulusi
- I-straight edge nobe intsambo lecinile ebusweni bema-pulley omabili (naka bubanti lobehlukene: linganisa kusuka emkhatsini wema-groove).
- Lithulusi lekulinganisa le-laser lelingena ku-groove: lisheshisa futsi lichanekile, likhombisa onkhe emaphutsa lamatsatfu kanye. Liyafaneleka kunoma nguyiphi i-drive lebalulekile nobe lenkhulu.
Lungisa i-twist kucala (faka ema-shim etinyaweni te-motor, hlola i-soft foot), bese i-angular, bese i-parallel (hambisa i-pulley ku-shaft nobe uhambise i-motor).
Kucinisa
Nangabe kucina kuncane ema-belt a-slip, acwebezele, ashise futsi akhale. Nangabe kucina kukhulu kakhulu ulayisha kakhulu ema-bearing e-motor newemshini, ugoba ema-shaft futsi unweba ema-belt. Imitsetfo yesandla ("inch yinye yekudlala", "kuze kuyekele kukhala") iphutsa kuto tonkhe tinhlangotsi. Linganisa.
Indlela 1: force-deflection (i-tension gauge nobe i-spring balance)
- Linganisa budze be-span t (budze lobukhululekile emkhatsini wema-tangent point ema-pulley).
- I-deflection lekufanele uyisebentise yi-1/64 ye-span: 16 mm emitheni ngayinye.
- Emkhatsini we-span, cindzetela i-belt yinye ngco nge-gauge bese ufundza emandla nayihambe lelibanga (beka i-straight edge ngetulu kwema-belt njengesikhombo).
- Catsanisa nemandla lafunwako kulithebula lalowenta nobe ku-lithulusi lekubala kucina. Ngaphansi kwalokufunwako: cinisa. Ngetulu kwa-1.5× lokufunwako: khulula.
- Hlola onkhe ema-belt ku-set; kuma-banded belt cindzetela yonkhe i-band bese usebentisa emandla elinani lema-rib.
deflection = span / 64
emandla nge-belt F ≈ T_static / 16 (kusuka ku-F = 4·T·δ / span)
Indlela 2: frequency (i-sonic tension meter)
Shaya i-span bese ulinganisa i-frequency yayo nge-sonic meter nobe i-app ye-vibration. Iyaphindvwa, ayidzingi emandla, futsi ifanele ema-span lamafisha nema-timing belt.
T = 4 × m × L² × f² (m kg/m, L span nge-m, f nge-Hz)
Sebentisa lithulusi lekubala i-frequency kute ushintje kucina lokufunwako kube yi-frequency lefunwako.
Indlela 3: kunwebeka
Dvweba imigca lemibili ebangeni lelilinganisiwe ku-belt lekhululekile bese ucinisa kuze lelibanga likhule ngemaphesenti lashiwo ngulowenta. Kuvamile kuma-flat belt nakulamanye ema-PU belt la-round.
Kucala nekuphindze ucinise
- Ema-V-belt lamasha ahlala kuma-groove futsi alahlekelwa kucina ngekushesha. Labanyenti labenta bacinisa ema-belt lamasha kakhulu (cishe 1.3× kwalokuvamile), bese bayaphindze bahlole emvakwema-awa la-4 kuya ku-24 asebenta futsi bacinise kabusha kuye kulokuvamile.
- Phindze uhlole emvakwelisonto lekucala, bese ulandzela luhlelo lolujwayelekile (kunakekela).
- Cinisa i-base ye-motor emvakwekushintja ngakunye.
Ema-timing belt: lokwehlukile
- Ungaze ugoce nobe ugobe i-timing belt: kuyigoba kakhulu kunelibanga layo lelincane kuphula imicu ngaphandle kwekutsi kubonakale.
- Faka i-belt kuma-pulley ngekuhambisa ema-shaft, hhayi ngekuyidlulisa phetulu kwe-flange.
- Kulinganisa ≈ ¼°. Ema-pulley lanema-flange agcina i-belt, kodvwa i-belt lehuhuta ku-flange isho kungalingani.
- Cinisa ngalokushiwo ngulowenta. Kucina lokukhulu kwenta ema-timing belt ahhushe futsi kuguga emazinyo; kucina lokuncane kwenta aveke emazinyo nangabe alayishiwe.
- Kuvamile kungadzingeki kuphindze ucinise emvakwekucala, kodvwa hlola emvakwelilanga lekucala kuma-drive lanzima.
Ema-guard (eNingizimu Afrika)
I-Driven Machinery Regulations, 2015 (Notice R.540 ngaphansi kwe-Occupational Health and Safety Act, 85 ka-1993, isebenta kusukela nga-30 September 2015), umtsetfo 3, idzinga kutsi basebentisi:
- bavikele ema-shaft, ema-pulley, emasondvo, ema-gear, ema-sprocket, ema-coupling netincenye letijikelekako letifananako;
- bafihle nobe bavikele ema-set screw, ema-key nema-bolt etincenyeni letijikelekako njengema-pulley;
- bavikele ema-belt, tintsambo nema-chain ekushayela;
- bavikele ngaphansi kwema-belt langetulu kwetindlela nobe tindzawo tekusebenta kute i-belt lephukile ingaweli bantfu (umhloli angakuyekelisa loku kuma-belt lalula lahamba kancane).
Sebentisa ema-guard e-mesh lakuvumela kutsi ubone futsi uhlole i-drive, nemigodzi lencane kangangekutsi iminwe ingafinyeleli ngekhatsi. Shiya indzawo yekulinganisa kucina ngelifasitelo.
Lesi sifinyeto nje. Hlola imitsetfo lesebentako nyalo nemitsetfo yekuphepha yendzawo yakho.
