I-V-belt isebenta njani

I-V-belt idlulisa emandla ngekuhuhuta emkhatsini wetinhlangotsi tayo nemabondza e-groove ye-pulley. Ayisebenti phansi ku-groove. Njengoba kucina kudonsela i-belt ngekhatsi ku-V, i-wedge iphindzaphindza emandla asetinhlangotsini: nge-angle ye-groove lecishe ibe ngu-38°, kuhuhuta lokusebentako kucishe kuphindvwe katsatfu kunalokwe-flat belt ku-pulley lefanako. Yingako i-V-belt ingatfwala emandla lamakhulu ngekucina lokulinganiselwe, futsi yingako i-belt lesigugile yaze yatsintsa phansi ku-groove icala ngekushesha kutsi i-slip.

Umbono lomkhuluEmandla lengawatfwala ancike ku-sekhishini, ku-diameter ye-pulley lencane, kulijubane nase-arc of contact. Ema-pulley lamancane lamakhudlwana atfwala emandla lamanyenti nge-belt ngayinye futsi aphilisa i-belt sikhatsi lesidze, ngoba i-belt igoba kancane.

Classical V-belt (Z, A, B, C, D, E)

I-V-belt yasekucaleni, lenebubanti lobuphindvwe cishe ka-1.6 kunekuphakama. Isatfolakala kuma-plant lamanyenti lamadzala, emishinini yemapulazi, kuma-pump nakuma-compressor. Emasekhishini la-classical alandzela i-DIN 2215 / ISO 4184 (metric) ne-RMA/MPTA IP-20 (inch, lapho A, B, C alingana ngebukhulu).

Emandla ayo: iyabeketela, ishibhile, itfolakala yonkhe indzawo, ikhona kubeketelela kungalingani lokuncane nekushaywa.
Imikhawulo: emandla lambalwa nge-belt ngayinye kunema-wedge belt; ema-drive adzinga ema-belt lamanyenti nobe ema-pulley labanti.
Lijubane lelikhulu levamile: cishe 30 m/s.

Sinika ema-classical belt etinhlobo te-Turboflex V-belts, wrapped ne-raw-edge cogged.

Narrow wedge belt (SPZ, SPA, SPB, SPC ne-3V/5V/8V)

Ema-narrow (wedge) belt ajulile uma kucatsaniswa nebubanti bawo (cishe 1.2). Imicu ihlala etulu kakhulu futsi incenye lenkhulu ye-sekhishini isekelwa ngemabondza e-groove, ngako-ke bubanti lobufanako butfwala emandla lamanyenti kakhulu kune-classical belt. Emasekhishini la-SP alandzela i-DIN 7753 / ISO 4184; ema-3V, 5V na-8V alandzela i-RMA/MPTA IP-22.

Emandla ayo: emandla lamanyenti endzaweni lencane: ema-belt lambalwa, ema-pulley lancane, umtfwalo lomncane ku-shaft.
Lijubane lelikhulu levamile: cishe 40 m/s (cinisekisa nalowenta kuma-raw-edge).
Caphela: ema-SP belt kufanele asebente kuma-groove e-SP. Ema-classical nema-narrow belt lanebubanti lobufanako (sib. B na-SPB) akashintjwa ngaphandle kwekuhlola i-groove.

KutfutfukisaKwakha kabusha i-drive lendzala ye-classical lenema-belt lamanyenti ngema-wedge belt kuvame kunciphisa linani lema-belt nebubanti be-pulley. Sebentisa umakhi we-drive nobe usicele kuhlolwa kwe-drive.

Bukhulu bemasekhishini

Bukhulu lobujwayelekile. I-datum width bubanti be-belt ku-datum line yayo, lehlala ku-datum diameter ye-pulley: i-diameter lesetjentiswa kuko konkhe kubala kwelijubane nebudze.

Ema-diameter lamancane ema-pulley nesisindvo ngemitha tinombolo letivamile letisetjentiswa ekubaleni; i-catalogue yalowenta iyona leyinhloko. Ema-banded nema-cogged avumela ema-pulley lamancane kulamanye emasekhishini.

Wrapped vs raw-edge cogged

Kwakhiwa	Kuyini	Kuhle ku
Wrapped	Lindvwangu lelisongela yonkhe i-belt.	Umsebenti lovamile, kushaywa, ema-drive ema-clutch, tindzawo letinelutfuli lapho lindvwangu livikela ekhatsi.
Raw-edge	Tinhlangotsi letisikiwe letingenalo lindvwangu: i-rubber ibamba i-groove ngco.	Kubamba lokukhulu, kusebenta kupholile.
Raw-edge cogged ("XP")	Raw-edge nemanochi ngaphansi.	Ema-pulley lamancane, lijubane lelikhulu, kushisa. Igoba kalula, ipholile futsi isebenta kahle cishe nga-2 % kune-wrapped belt (US DOE). Ema-pulley lafanako ne-sekhishini ye-wrapped.

Banded belt (ema-V-belt lahlanganisiwe)

Ema-V nobe ema-wedge belt lamabili kuya kulasihlanu (nobe ngetulu) lahlanganiswe yi-band ngetulu. I-band ivimbela ema-belt kutsi aphenduke nobe aveke ngaphandle ngemitfwalo leshaya-shayako.

Sebentisa ku: ema-head-rig ema-sawmill, ema-chipper, ema-crusher, ema-hammer mill, ema-piston compressor, ema-drive lanema-centre distance lamadze nobe ema-shaft lamile, kanye nanoma nguyiphi i-drive lapho ema-belt laphendukile kuma-groove.

Simo sema-groove sibaluleke kakhuluI-banded belt ayikhoni kulungisa ema-groove lagugile ngalokungalingani njengema-belt lahlukene. Hlola ema-groove nge-gauge ngaphambi kwekufaka.

Double-V (hexagonal) belt

Sekhishini lenetinhlangotsi letisitfupha lesebenta ngetinhlangotsi tombili. Isetjentiswa kuma-serpentine drive lanema-pulley ngetinhlangotsi tombili te-belt: ema-harvester, leminye imishini yemapulazi nema-drive lanema-shaft lamanyenti.

Poly-V (ribbed) belt

I-belt leyi-flat lencane lenema-rib e-V ngebudze (ema-profile PH, PJ, PK, PL, PM; ISO 9982). Ihlanganisa kugoba kwe-flat belt nekubamba kwema-rib e-V.

Sebentisa ku: ema-drive lamancane lane-ratio lenkhulu, ema-pulley lamancane, lijubane lelikhulu, ema-fan, imishini yekugcwalisa emabhodlela nekupakisha, ema-machine tool.
Caphela: kulinganisa kufanele kube ngcono kunema-V-belt (cishe ¼°). Cacisa nge-profile, linani lema-rib nebudze, sib. PJ 1016 × 8 ribs.

Variable-speed belt

Ema-belt labanti lancane lasebenta kuma-variable-pitch (variator) pulley, lapho tincenye te-pulley tihlukana nobe tisondzelana kute tishintje i-diameter nelijubane. Acaciswa ngebubanti phetulu, i-angle nebudze (luhla lwe-RMA lwema-inch nobe lwe-DIN lwe-metric). Atfolakala kuma-harvester, kuma-variator lamadzala nakulamanye ema-feeder.

Timing (synchronous) belt

Ema-belt lanemazinyo labamba ema-pulley lanemazinyo: ayi-slip, i-ratio ayishintji, asebenta kahle cishe nga-98 % sonkhe sikhatsi sekuphila kwe-belt (US DOE). Asetjentiswa lapho sikhatsi sibalulekile (imishini yekupakisha, ema-sizer kuma-packhouse, kuphrinta, i-automation) futsi nyalo nekonga gesi kuma-drive langashintji.

Umndeni	Ema-profile	Emanotsi
Trapezoidal, inch	MXL, XL, L, H, XH, XXH	Imishini lemidzala, umsebenti lolula kuya kulophakatsi. ISO 5296.
Trapezoidal, metric	T2.5, T5, T10, T20; AT5, AT10, AT20	Ema-belt e-PU nemicu ye-steel nobe ye-aramid. AT = lizinyo lelinzima.
Curvilinear (HTD)	3M, 5M, 8M, 14M, 20M	Emazinyo layindingilizi: i-torque lenkhulu, kweca lokuncane. ISO 13050.
Modified curvilinear (STD)	S3M, S5M, S8M, S14M	Umsindvo lomncane, kubeka lokuchanekile.
Lakhetsekile	Double-sided, open-end (asikiwe ngema-clamp), coated (sib. Linatex nobe ema-grip coat), roller-mill	Kutfwala, kunyakata ngco, ema-serpentine drive. Budze nema-coating kwentiwa ngekuvuma kwakho.

Cacisa njengaku: pitch length nobe linani lemazinyo, i-profile, bubanti, sib. 1600-8M-30 = 1 600 mm pitch length, HTD pitch ya-8 mm, bubanti ba-30 mm. Sebentisa lithulusi lekubala ema-timing belt.

Akusiko kushintja njeEma-timing belt aqinile futsi anemsindvo lomkhulu, adlulisa kushaywa nekunyakatisa, futsi adzinga kulinganisa lokuchanekile (≈ ¼°). Akakahle kuma-drive lashaywa kakhulu. Kuma-centrifugal fan nema-pump, kususa i-slip kwenyusa lijubane nemandla: phindze uhlole bukhulu bema-pulley.

PU belt leyi-round (Polycord)

Intsambo leyi-round ye-polyurethane, leshiselwa ebudzeni lobufunako emsebentini. Yona lesisekelo sema-packline etitselo: ema-singulator, ema-roller table, ema-sizer drive nema-conveyor lalula. Itfolakala ibushelelezi nobe imahhadla, nangema-diameter nebulukhuni lobehlukene.

Budze bubekwa ngekunwebeka: i-belt leyi-round ivame kusikwa imfisha ngemaphesenti lambalwa kunendlela leyihambako; landzela linani lekunwebeka lalowenta ku-diameter nebulukhuni.
Shisela nge-blade yekushisela ne-clamp lefanele kute kuhlanganisa kube ngco futsi kungancipheki. Kuphuka lokunyenti kwema-belt la-round kudalwa kushisela lokubi.
Gcina intsambo leyengetiwe nelikhithi lekushisela eceleni kwe-line ngesikhatsi sesizini.

Ema-belt la-flat nema-conveyor belt

Ema-flat belt (lentiwe nge-polyamide nobe nge-elastomer) asebenta kahle ngelijubane lelikhulu kuma-pulley lagobile: ema-tangential drive kuma-textile mill, ema-folder-gluer, kupakisha. Ema-conveyor belt lalula atfwala umkhicito kuma-line ekupakisha nekudla, kuma-packhouse nakuma-warehouse; cacisa bubanti, budze, indzawo yetulu (lebushelelezi, lebambako, yekudla), luhlobo lwekuhlanganisa (i-finger splice, ema-fastener) ne-carcass.

Kutfola i-belt

Fundza timphawu emuva ku-belt lendzala (tsatsa sitfombe ekukhanyeni lokuhle; jikisa i-belt utfole indzawo lehlantekile).
Kute timphawu? Linganisa bubanti phetulu ne-kuphakama nge-vernier bese ucatsanisa ne-thebula yemasekhishini. Kuphakama lokucishe kube ngu-0.6 × bubanti → classical; cishe 0.8 × bubanti → narrow wedge.
Budze: linganisa budze bangaphandle be-belt lendzala nge-tape (itawube inwebekile), nobe kuncono, linganisa ema-pulley ne-centre distance emshinini bese usebentisa lithulusi lekutfola i-belt.
Hlola i-groove nge-groove gauge kute ucinisekise i-classical nobe i-SP.
Sitfumelele titfombe netinombolo nge-WhatsApp; sitawuyitfola.
