Ema-diameter achazwa

Diameter	Kuyini	Isetjentiselwa
Datum Ø (d_d)	I-diameter ku-datum width ye-groove (lapho kuhamba khona i-datum line ye-belt).	Konkhe kubala kwelijubane, i-ratio nebudze kuma-SP nema-classical belt (ISO 4183).
Ø yangaphandle (d_e)	Ngetulu kwema-flange: yona kuphela lelinganiseka kalula.	Kulinganisa emsebentini. d_d ≈ d_e − 2b.
Pitch Ø	Kuma-timing pulley, i-diameter ye-pitch line ye-belt: p × z / π.	Kubala ema-timing drive.
Effective Ø	Luhlelo lwe-RMA (3V/5V/8V): lusekelwe ngaphandle kwe-belt.	Emathebula ema-narrow belt e-inch.

d_datum ≈ d_yangaphandle − 2 × b b (lokuncane, ISO 4183): Z/SPZ 2.0 · A/SPA 2.75 · B/SPB 3.5 · C/SPC 4.8 · D 8.1 · E 9.6 mm

Ema-groove profile

Ema-pulley e-classical nema-narrow alandzela i-ISO 4183 / DIN 2211 (narrow) ne-DIN 2217 (classical). I-angle ye-groove incike ku-diameter ye-pulley: ema-pulley lamancane asebentisa i-angle lencane (cishe 32–34°) futsi lamakhulu i-angle lenkhulu (cishe 36–38°), ngoba i-belt legoba ku-pulley lencane iyabanta phansi.

Ema-groove e-SP afanele ema-narrow (SP) belt, futsi kuvamile ne-classical belt lene-datum width lefanako. Ema-groove e-classical ajulile kancane kakhulu kuma-SP belt: ungaze ufake ema-SP belt kuma-groove e-classical ngaphandle kwekuhlola.
I-belt kufanele ihlale ilingana, nobe ingetulu kancane, kwetulu kwe-groove. I-belt lengekhatsi kakhulu isho i-groove lesigugile nobe i-belt lengasiyo.
I-belt akukafanele itsintse phansi ku-groove.

Kugugeka kwema-groove nekuhlola nge-gauge

Lutfuli, i-slip netindzawo letiguga (umoba, ematiyo, emalahle, sihlabatsi) kuguga emabondza e-groove kube nesimo sesitja. I-groove lesigugile ivumela i-belt kutsi ingene, ilahlekelwe kubamba kwe-wedge, i-slip; i-belt bese iyasha futsi icwebezele. Kufaka ema-belt lamasha kuma-groove lagugile kuyimbangela levame kakhulu ye-"lama-belt akaphili".

Sebentisa i-groove gauge (i-template) ye-sekhishini ne-diameter ye-pulley.
Yibambe ku-groove ubuke ekukhanyeni: i-gauge kufanele ihlale kahle emabondzeni omabili. Kukhanya emkhatsini we-gauge nelibondza, nobe sitebhisi nobe sitja lesibanjwa ngelulwanyana, kusho kutsi shintja i-pulley. Landzela umkhawulo walowenta i-gauge nangabe ukhona.
Phansi kwe-groove lokucwebezelako kusho kutsi i-belt beyitsintsa phansi: shintja.
Kugugeka lokungalingani emkhatsini wema-groove (lenye ijulile kunaletinye) nako kubulala ema-banded belt.

UmtsetfoNawushintja ema-belt ku-drive lebalulekile, hlola ema-pulley nge-gauge. Nawushintja i-pulley, shintja nema-belt.

Lijubane le-rim netinsimbi

Insimbi	Kusetjentiswa lokuvamile	Umkhawulo levamile welijubane le-rim
Grey cast iron	Ema-V-belt pulley lasesitokweni	≈ 30 m/s
Ductile (SG) iron / steel	Lijubane lelikhulu, umsebenti lonzima, ema-diameter lamakhulu	Ngetulu: ngekwemkhawulo nekulinganisa kwalowenta
Aluminium	Ema-timing pulley, ema-drive lalula	Ngekwemkhawulo walowenta
Steel (lehlanganisiwe)	Ema-pulley lamakhulu kakhulu, ema-profile lakhetsekile	Ngekwemklamo

Ingoti yekuciphitsekaEma-pulley e-grey cast iron angaciphitseka nangabe asebenta ngetulu kwemkhawulo welijubane le-rim, sibonelo nangabe i-pulley ye-fan ifakwa ku-motor lesheshako nobe i-VSD ibekwa ngetulu kwa-50 Hz. Hlola nge-lithulusi lekubala lijubane le-rim.

Balancing

Ema-pulley lasesitokweni avame kuba ne-static balance. Ema-pulley elijubane lelikhulu, ema-pulley labanti nema-pulley emishinini lenyakatako kalula (ema-fan, ema-centrifuge, ema-decanter) kufanele abe ne-dynamic balance ngebanga lelifanele ngekwe-ISO 21940 (leyayi-ISO 1940-1). Kungalingani kubonakala njengekunyakatisa nga-1× lijubane le-pulley. Kubhoboza i-bore lengekho emkhatsini nako kwenta i-pulley ingalingani.

Tinhlobo tema-pulley

Ema-taper-bore pulley atsatsa i-taper-lock bush: i-pulley yinye ingena kuma-shaft lamanyenti. Le yi-standard kuma-drive lamanyenti lamasha.
Ema-pilot-bore pulley ata ne-bore lencane lekufanele ibhobozwe ilingane ne-shaft, ne-keyway ne-set screw.
QD / split-taper (avamile emishinini ye-America) asebentisa i-bush lene-flange.
Ema-variable-pitch pulley kuma-variable-speed belt nekulungisa lijubane kancane.
Ema-pulley la-flat nalagobile kuma-flat belt.

Ema-pulley lentiwe ngekuvuma kwakho

Sinika ema-pulley lentiwe ngekwe-drawing nobe ngesibonelo sakho: ema-diameter langasiwo e-standard, ema-bore nema-keyway lakhetsekile, emasekhishini lamanyenti ku-hub yinye, ema-hub lamadze, nema-pulley ekushintja emishinini lemidzala levela phesheya. Sitfumelele sitfombe ne-diameter yangaphandle, linani neluhlobo lwema-groove, i-bore ne-keyway, nebudze be-hub.

Ema-timing pulley

Cacisa i-profile (sib. HTD 8M), linani lemazinyo, bubanti be-belt, ane-flange nobe akanayo, ne-bore (pilot nobe taper-lock).
I-pulley lencane ivame kuba nema-flange ngetinhlangotsi tombili; kuma-shaft lamile faka ema-flange nase-pulley lengaphansi.
Hlola emazinyo labambene: okungenani la-6 ku-pulley lencane.
Emazinyo e-timing pulley lagugile (agobile nobe acwebezelako) aguga ema-belt lamasha masinyane: wushintje kanyekanye.

Ema-taper-lock bush

I-taper-lock bush yi-sleeve lesikiwe, legobile lebopha i-pulley (nobe i-sprocket nobe i-coupling) ku-shaft. Kucinisa tikulufo kudonsela i-bush ngekhatsi ku-bore ye-pulley legobile, kuyicindzetele ku-shaft. I-pulley yinye ingena kuma-shaft lamanyenti ngekushintja nje i-bush.

Ikhodi yebukhulu: tinombolo letimbili tekugcina budze be-bush ngemashumi e-inch (2517 → 1.7″ ≈ 44 mm); letimbili tekucala tikhombisa bukhulu.
Bukhulu ngabunye bemukela ema-bore kuze kufike kulenkhulu, e-metric nobe e-inch, ne-keyway ngekwe-standard ye-shaft.
Faka i-bush ngalicala linye: hub-side (H) nobe face-side (F) kuye nge-pulley. Hlola ngaphambi kwekufaka kute tikulufo tifinyeleleke.

Tfola i-bush ye-shaft yakho: kutfola i-taper bush.

Kufaka i-bush

Hlanza tonkhe tindzawo: i-bore, i-shaft ne-taper ye-bush. Ungafaki emafutsa, i-grease nobe i-anti-seize kuma-taper nobe etikulufweni: kwenta i-bush icine kakhulu futsi kungaciphitsa i-pulley.
Beka i-bush ku-pulley, linganisa tigamu temigodzi, bese ufaka tikulufo ungaticinisi (gcoba emafutsa kancane etintsanjeni kuphela nangabe lowenta asho).
Faka konkhe ku-shaft (ne-key) bese ukubeka endzaweni.
Cinisa tikulufo ngekushintshana nangalokulinganako kuze kufike ku-torque leshiwo.
Shaya kancane licala lelikhulu le-bush nge-drift nesando lesitsambile, bese uphindze ucinise nge-torque. Phindza kuze i-torque ingabe isehla.
Gcwalisa imigodzi lengenalutfo nge-grease kute kungangeni kungcola.
Phindze uhlole i-torque emvakwekusebenta sikhashana.

Kukhipha i-bush

Khipha tonkhe tikulufo.
Gcoba emafutsa etintsanjeni nasekhanda lesikulufo sinye bese usifaka emgodzini wekukhipha (ligamu lemgodzi lelinentsambo ku-bush).
Sicinise: i-bush icindzetelwa iphume ku-taper futsi konkhe kuyakhululeka.

Lithebula lebukhulu bema-bush

Tinombolo letivamile tama-taper-lock lavamile (lwe-Fenner). Ema-torque ayinombolo levamile leshicilelwe: sebentisa njalo inombolo lebhalwe ku-bush nobe ephepheni lalowenta nangabe yehlukile.
