Upangiri Wathunthu wa V-Belt Pulleys: Katswiri Wothandizira

1. V-Belt Pulley Construction ndi Anatomy

Core Components

Grooved Rim

Imakhala ndi ma grooves opangidwa bwino ndi V ofananira ndi mbiri ya malamba

Makona amasiyana malinga ndi muyezo (38° wa classical, 40° pagawo lopapatiza)

Kumaliza kwapamwamba ndikofunikira kuti mugwire bwino lamba komanso mawonekedwe amavalidwe

Hub Assembly

Chigawo chapakati chokwera cholumikizira ku shaft yoyendetsa

Itha kuphatikizira makiyi, zomangira, kapena makina apadera okhoma

Kulekerera kwabwino kumasungidwa ku miyezo ya ISO kapena ANSI

Kapangidwe

Solid Hub Pulleys: Kupanga kwachidutswa chimodzi chokhala ndi zinthu zopitilira pakati pa hub ndi rim

Spoked Pulleys: Mawonekedwe a mikono yozungulira yolumikizana ndi nthiti

Ma Pulleys Opanga Webusaiti: Disiki yopyapyala, yolimba pakati pa hub ndi rim

Zofunikira Zakuthupi

Cast Iron (GG25/GGG40)
Zinthu zodziwika bwino zamafakitale zomwe zimapereka kugwedera kwabwino kwambiri

Chitsulo (C45/St52)
Kwa ma torque apamwamba omwe amafunikira mphamvu zapamwamba

Aluminium (AlSi10Mg)
Njira yopepuka yogwiritsira ntchito mothamanga kwambiri

Polyamide (PA6-GF30)
Amagwiritsidwa ntchito pazakudya komanso m'malo osamva phokoso

2. Miyezo ya Padziko Lonse ndi Zigawo

American Standard (RMA/MPTA)

Zojambula Zapamwamba za V-Belt
Osankhidwa ndi zilembo A (1/2"), B (21/32"), C (7/8"), D (1-1/4"), E (1-1/2")

Makona a groove: 38° ± 0.5°

Zomwe zimagwiritsidwa ntchito: Zoyendetsa mafakitale, zida zaulimi

Narrow Gawo Pulleys
3V (3/8"), 5V (5/8"), 8V (1") mbiri

Kuchulukana kwamphamvu kuposa malamba akale

Zodziwika m'makina a HVAC komanso ma drive apamwamba kwambiri

European Standard (DIN/ISO)

SPZ, SPA, SPB, SPC Pulleys
Ma metric amafanana ndi mndandanda wazakale zaku America

SPZ ≈ gawo, SPA ≈ AX gawo, SPB ≈ B gawo, SPC ≈ C gawo

Makona a Groove: 34 ° kwa SPZ, 36 ° kwa SPA/SPB/SPC

Narrow Mbiri Pulleys
XPZ, XPA, XPB, XPC mayina

Zogwirizana ndi 3V, 5V, 8V mbiri yokhala ndi miyeso ya metric

Amagwiritsidwa ntchito kwambiri m'mafakitale aku Europe

3. Zolemba Zaumisiri ndi Deta ya Umisiri

Makulidwe Ovuta

Parameter	Tanthauzo	Kuyeza
Pitch Diameter	Kugwira ntchito m'mimba mwake	Kuyezedwa pamzere wa belt pitch
Kunja Diameter	Chidutswa chonse cha pulley	Zofunikira pakuwongolera nyumba
Bore Diameter	Kuyika shaft kukula	Kulekerera kwa H7 wamba
Kuzama kwa Groove	Malo okhala lamba	Zimasiyanasiyana ndi lamba
Hub Protrusion	Axial positioning reference	Kumatsimikizira kulondola koyenera

Makhalidwe Antchito

Kuchepetsa Liwiro
Kuchuluka kwa RPM kumawerengeredwa potengera zinthu ndi m'mimba mwake

Chitsulo choponyera: ≤ 6,500 RPM (kutengera kukula)

Chitsulo: ≤ 8,000 RPM

Aluminiyamu: ≤ 10,000 RPM

Mphamvu ya Torque
Zimatsimikiziridwa ndi groove count ndi lamba gawo

Malamba akale: 0.5-50 HP pa poyambira

Malamba opapatiza: 1-100 HP pa poyambira

4. Mounting Systems ndi Kuyika

Zosintha za Bore

Plain Bore

Imafunika makiyi ndi zomangira

Yankho lachuma kwambiri

Zodziwika pamapulogalamu okhazikika

Taper-Lock® Bushings

Makina okwera mwachangu amakampani

Imakhala ndi miyeso yosiyanasiyana ya shaft

Imathetsa kufunika kwa makiyi

Zithunzi za QD

Mapangidwe osavuta kuchotsa

Zodziwika m'malo okonza-zolemera

Zimafunika kufananiza shaft diameter

Kukhazikitsa Njira Zabwino Kwambiri

Njira Zogwirizanitsa
Kuyanjanitsa kwa laser kumalimbikitsidwa pama drive ovuta

Kusintha kwa angular ≤ 0.5 °

Parallel kuchepetsa ≤ 0.1mm pa 100mm kutalika

Njira Zolimbitsa Thupi
Kuvuta koyenera ndikofunikira pakuchita bwino

Muyeso wokhotakhota mwamphamvu

Sonic tension mita kuti muthe kulondola

5. Maupangiri a Umisiri Wantchito

Njira Zosankhira

Dziwani Zofunikira Zamagetsi

Werengetsani kapangidwe ka HP kuphatikiza zinthu zantchito

Akaunti yoyambira nsonga za torque

Dziwani Zolepheretsa Malo

Kuchepetsa mtunda wapakati

Zoletsa za envulopu ya nyumba

Kuganizira Zachilengedwe

Kutentha kosiyanasiyana

Kuwonekera kwa mankhwala

Tinthu toyambitsa matenda

Ntchito Zokhudza Makampani

HVAC Systems
Ma pulleys a SPB okhala ndi kusanja kosinthika

Kukonza Chakudya
Kupanga kwachitsulo chosapanga dzimbiri kapena polyamide

Zida Zamigodi
Mapuleti olemera a SPC okhala ndi ma taper-lock bushings

6. Kusamalira ndi Kuthetsa Mavuto

Common Kulephera Modes

Mitundu ya Groove Wear

Kuvala kosiyana kumawonetsa kusalinganika

Miyendo yopukutidwa ikuwonetsa kutsetsereka

Kupirira Zolephera
Nthawi zambiri zimayamba chifukwa cha kukanika kwa lamba kosayenera

Yang'anirani kuchuluka kwa ma radial

Kusamalira Kuteteza

Kuyang'ana kowoneka bwino

Kusanthula kwa vibration kwa ma drive ovuta

Machitidwe owunikira ma lamba

Kuti mudziwe zambiri zaukadaulo kapena kufunsa kalozera kamangidwe ka uinjiniya, chonde lemberanigulu lothandizira luso. Mainjiniya athu alipo kuti akuthandizeni kufotokoza njira yoyenera ya pulley pazofunikira zanu.
