V-belt pulleys (inonziwo mashefu) zvinhu zvakakosha mumakanika ekufambisa simba masisitimu. Izvi zvakanyatso-engineered zvikamu zvinonyatso fambisa kutenderera kwekufamba uye simba pakati pemashaft uchishandisa trapezoidal V-mabhandi. Iyi nyanzvi yereferenzi inotungamira inopa ruzivo rwakakwana rwehunyanzvi nezve V-belt pulley magadzirirwo, zviyero, zvakatemwa, uye yakakodzera sarudzo maitiro.
1. V-Belt Pulley Kuvaka uye Anatomy
Core Components
Grooved Rim
Zvimiro zvakanyatsogadzirwa V-shaped grooves inoenderana nebhandi profiles
Makona eGroove anosiyana neyakajairwa (38° yeclassical, 40° yechikamu nhete)
Surface kupedzisa yakakosha kune yakakwana bhandi kubata uye kupfeka maitiro
Hub Assembly
Central mounting chikamu chekubatanidza kune drive shaft
Inogona kubatanidza makiyi, maseru masiruu, kana akasarudzika ekukiya nzira
Bore kushivirira kunochengetwa kune ISO kana ANSI zviyero
Chimiro
Solid Hub Pulleys: Imwe-chidimbu dhizaini ine inoenderera zvinhu pakati pehub uye rim
Spoked Pulleys: Inoratidza radial maoko anobatanidza hub kune rim
Webhu Dhizaini Pulleys: Yakatetepa, yakasimba disc pakati pehub uye rim
Zvinotaurwa Nezvinhu
Cast Iron (GG25/GGG40)
Yakawanda yakajairika maindasitiri zvinhu zvinopa yakanakisa vibration damping
Simbi (C45/St52)
Kune yakakwirira-torque yekushandisa inoda simba repamusoro
Aluminium (AlSi10Mg)
Huremu huremu hwemamwe maapplication akakwira-kumhanya
Polyamide (PA6-GF30)
Inoshandiswa munzvimbo dzekudya uye dzinonzwa ruzha
2. Global Standards uye Classifications
Chiyero cheAmerica (RMA/MPTA)
Classical V-Belt Pulleys
Yakasarudzwa nemabhii A (1/2"), B (21/32"), C (7/8"), D (1-1/4"), E (1-1/2")
Standard groove angles: 38° ± 0.5°
Typical applications: Industrial Drives, zvekurima zvekushandisa
Narrow Chikamu Pulleys
3V (3/8"), 5V (5/8"), 8V (1") nhoroondo
Higher power density kupfuura classical mabhandi
Yakajairika muHVAC masisitimu uye yakakwira-inoshanda madhiraivha
European Standard (DIN/ISO)
SPZ, SPA, SPB, SPC Pulleys
Metric inofananidzira kuAmerican classical series
SPZ ≈ A chikamu, SPA ≈ AX chikamu, SPB ≈ B chikamu, SPC ≈ C chikamu
Groove angles: 34 ° yeSPZ, 36 ° yeSPA/SPB/SPC
Narrow Profile Pulleys
XPZ, XPA, XPB, XPC mazita
Inopindirana ne3V, 5V, 8V profiles ine metric dimensions
Inoshandiswa zvakanyanya muEurope maindasitiri emidziyo
3. Zvinyorwa zveTechnical uye Engineering Data
Critical Dimensions
| Parameter | Tsanangudzo | Kuyera |
| Pitch Diameter | Kubudirira kushanda dhayamita | Yakayerwa pamutsetse webhandi |
| Kunze Diameter | Yakazara pulley dhayamita | Yakakosha pakuchenesa imba |
| Bore Diameter | Shaft mounting size | H7 kushivirira kwakajairika |
| Groove Depth | Belt seating position | Inosiyana nechikamu chebhandi |
| Hub Protrusion | Axial positioning reference | Inosimbisa kurongeka kwakaringana |
Performance Characteristics
Speed Limitations
Maximum RPM yakaverengerwa zvichibva pane zvinhu uye dhayamita
Cast iron: ≤ 6,500 RPM (zvinoenderana nekukura)
Simbi: ≤ 8,000 RPM
Aluminium: ≤ 10,000 RPM
Torque Capacity
Yakatemerwa negroove count uye bhandi chikamu
Classical mabhandi: 0.5-50 HP per groove
Mabhandi akamanikana: 1-100 HP pagorofu
4. Mounting Systems uye Installation
Bore Configurations
Plain Bore
Inoda keyway uye kuseta screws
Yakanyanya hupfumi mhinduro
Inowanikwa mune yakagadziriswa-speed application
Taper-Lock® Bushings
Indasitiri-yakajairwa inokurumidza-gomo system
Inogara akasiyana shaft saizi
Inobvisa kudiwa kwekiyi nzira
QD Bushings
Kurumidza-detachable design
Yakakurumbira mukuchengetedza-inorema nharaunda
Inoda kuenzanisa shaft dhayamita
Installation Best Practices
Kurongeka Matanho
Laser alignment inokurudzirwa kune yakakosha madhiraivha
Angular misalignment ≤ 0.5 °
Parallel offset ≤ 0.1mm per 100mm span
Tensioning Nzira
Kushushikana kwakakodzera kwakakosha pakuita
Chiyero chekumanikidza
Sonic tension metres yekunyatsoita
5. Mirayiridzo yekushandisa Injiniya
Sarudzo Methodology
Sarudza Simba Zvinodiwa
Verenga dhizaini HP inosanganisira sevhisi zvinhu
Account yekutanga-up torque peaks
Ziva Space Constraints
Pakati pekugumira
Zvirambidzo zvehamvuropu yedzimba
Mafungiro Ezvakatipoteredza
Tembiricha range
Kuratidzwa kwemakemikari
Particulate kusvibiswa
Indasitiri-Yakananga Applications
HVAC masisitimu
SPB pulleys ane dynamic balancing
Food Processing
Simbi isina tsvina kana polyamide kuvaka
Migodhi Equipment
Heavy-duty SPC pulleys ane taper-lock bushings
6. Maintenance uye Troubleshooting
Common Kukundikana Modes
Groove Wear Patterns
Kupfeka zvisina kuenzana kunoratidza kusarongeka
Mapolish grooves anoratidza kutsvedza
Kutakura Kukundikana
Kazhinji zvinokonzerwa nekusagadzikana kwebhanhire
Tarisa kune yakawandisa radial mitoro
Preventive Maintenance
Kuongororwa kwekuona nguva dzose
Vibration ongororo yeakakosha madhiraivha
Belt tension monitoring systems
Kuti uwane rumwe rubatsiro rwehunyanzvi kana kukumbira yedu engineering dhizaini gwara, ndapota taura neyedutechnical support team. Mainjiniya edu aripo kuti abatsire kutsanangura yakanakira pulley mhinduro kune yako chaiyo application zvinodiwa.
