V-belt e šoma bjang

V-belt e fetiša maatla ka go šidinyana magareng ga mahlakore a yona le maboto a groove ya pulley. Ga e šome fase ka groove. Ge go tiiša go goga belt ka gare ga V, wedge e oketša maatla a mahlakoreng: ka angle ya groove ya go ka ba 38°, go šidinyana mo go šomago go ka ba makga a mararo go feta ga flat belt go pulley ye e swanago. Ke ka fao V-belt e kgonago go rwala maatla a magolo ka go tiiša mo go lekanetšego, gomme ke ka fao belt ye e jegilego go fihla e kgwatha fase ga groove e thomago go thellela ka pela.

Kgopolo ye bohlokwaMaatla ao e ka a rwalago a ithekgile ka sekšene, diameter ya pulley ye nnyane, lebelo le arc of contact. Dipulley tše nnyane tše kgolwanyana di rwala maatla a mantši ka belt gomme di phediša belt nako ye telele, ka gobane belt e kobega ganyane.

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

V-belt ya mathomo, yeo bophara bja yona bo lekanago le bophagamo makga a ka bago 1.6. E sa hwetšwa di-plant tše ntši tša kgale, metšheneng ya dipolase, di-pump le di-compressor. Disekšene tša classical di latela DIN 2215 / ISO 4184 (metric) le RMA/MPTA IP-20 (inch, moo A, B, C di lekanago ka bogolo).

Maatla a yona: e a kgotlelela, e theko ya fase, e hwetšwa gohle, e kgotlelela go se lekane mo gonnyane le go betwa.
Mellwane: maatla a mannyane ka belt go feta di-wedge belt; di-drive di nyaka dibelt tše ntši goba dipulley tše dipharephare.
Lebelo le legolo le le tlwaelegilego: go ka ba 30 m/s.

Re fa di-classical belt tša mehuta ya Turboflex V-belts, wrapped le raw-edge cogged.

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

Di-narrow (wedge) belt di tseneletše ge di bapetšwa le bophara bja tšona (go ka ba 1.2). Methapo e dula godimo kudu gomme karolo ye kgolo ya sekšene e thekgwa ke maboto a groove, ka gona bophara bjo bo swanago bo rwala maatla a mantši kudu go feta classical belt. Disekšene tša SP di latela DIN 7753 / ISO 4184; 3V, 5V le 8V di latela RMA/MPTA IP-22.

Maatla a yona: maatla a mantši lefelong le lennyane: dibelt tše mmalwa, dipulley tše dinnyane, morwalo wo monnyane go shaft.
Lebelo le legolo le le tlwaelegilego: go ka ba 40 m/s (netefatša le modiri go di-raw-edge).
Hlokomela: di-SP belt di swanetše go šoma go di-groove tša SP. Di-classical le di-narrow belt tša bophara bjo bo swanago (mohl. B le SPB) ga di fetošwe ntle le go lekola groove.

Go kaonafatšaGo dira lefsa drive ya kgale ya classical ya dibelt tše ntši ka di-wedge belt gantši go fokotša palo ya dibelt le bophara bja pulley. Diriša modiri wa drive goba o re kgopele tekolo ya drive.

Bogolo bja disekšene

Bogolo bjo bo tlwaelegilego. Datum width ke bophara bja belt go datum line ya yona, ye e dulago go datum diameter ya pulley: diameter ye e šomišwago go dipalo ka moka tša lebelo le botelele.

Di-diameter tše nnyane tša dipulley le boima ka mitara ke dipalo tše di tlwaelegilego tše di šomišwago go bala; khatalogo ya modiri ke yona ye bohlokwa. Di-banded le di-cogged di dumelela dipulley tše nnyane go disekšene tše dingwe.

Wrapped vs raw-edge cogged

Go agwa	Ke eng	E loketše
Wrapped	Lešela leo le phuthelago belt ka moka.	Mošomo wa kakaretšo, go betwa, di-drive tša di-clutch, mafelo a lerole moo lešela le šireletšago ka gare.
Raw-edge	Mahlakore a a sehilwego ao a se nago lešela: rubber e swara groove thwi.	Go swara mo go golo, go šoma go tonya.
Raw-edge cogged ("XP")	Raw-edge le dinotšhe ka fase.	Dipulley tše nnyane, lebelo le legolo, phišo. E kobega gabonolo, e šoma e tonya gomme e šoma gabotse ka go ka ba 2 % go feta wrapped belt (US DOE). Dipulley tše di swanago le tša sekšene ya wrapped.

Banded belt (di-V-belt tše di kopantšwego)

Di-V goba di-wedge belt tše pedi go ya go tše hlano (goba go feta) tše di kopantšwego ke band godimo. Band e thibela dibelt gore di se retologe goba di se tšwe ka merwalo ye e betago.

Diriša go: di-head-rig tša di-sawmill, di-chipper, di-crusher, di-hammer mill, di-piston compressor, di-drive tša centre distance ye telele goba di-shaft tše di emego, le drive efe goba efe moo dibelt di retologilego go di-groove.

Seemo sa di-groove se bohlokwa kuduBanded belt ga e kgone go lokiša di-groove tše di jegilego ka go se lekane bjalo ka dibelt tše di arogantšwego. Lekola di-groove ka gauge pele o tsenya.

Double-V (hexagonal) belt

Sekšene ya mahlakore a selelago ye e šomago ka mahlakore ka moka a mabedi. E šomišwa go di-serpentine drive tšeo di nago le dipulley mahlakoreng ka moka a belt: di-harvester, metšhene ye mengwe ya dipolase le di-drive tša di-shaft tše ntši.

Poly-V (ribbed) belt

Belt ye phaphathi ye tshesane ye e nago le di-rib tša V ka botelele (di-profile PH, PJ, PK, PL, PM; ISO 9982). E kopanya go kobega ga flat belt le go swara ga di-rib tša V.

Diriša go: di-drive tše nnyane tša ratio ye kgolo, dipulley tše nnyane, lebelo le legolo, di-fan, metšhene ya go tlatša mabotlelo le go phuthela, di-machine tool.
Hlokomela: go lekanetša go swanetše go nepagala kudu go feta di-V-belt (go ka ba ¼°). Hlaloša ka profile, palo ya di-rib le botelele, mohl. PJ 1016 × 8 ribs.

Variable-speed belt

Dibelt tše dipharephare tše tshesane tše di šomago go di-variable-pitch (variator) pulley, moo dikarolo tša pulley di arogana goba di batamelana go fetoša diameter le lebelo. Di hlalošwa ka bophara bja godimo, angle le botelele (lenaneo la RMA la inch goba la DIN la metric). Di hwetšwa go di-harvester, di-variator tša kgale le di-feeder tše dingwe.

Timing (synchronous) belt

Dibelt tše di nago le meno tše di swarago dipulley tše di nago le meno: ga di thellele, ratio ga e fetoge, di šoma gabotse ka go ka ba 98 % nako ka moka ya bophelo bja belt (US DOE). Di šomišwa moo nako e lego bohlokwa (metšhene ya go phuthela, di-sizer go di-packhouse, go gatiša, automation) gomme bjale gape le go boloka enetši go di-drive tše di sa fetogego.

Hlaloša bjalo ka: pitch length goba palo ya meno, profile, bophara, mohl. 1600-8M-30 = 1 600 mm pitch length, HTD pitch ya 8 mm, bophara bja 30 mm. Diriša sedirišwa sa go bala di-timing belt.

Ga se go fetoša felaDi-timing belt di tiile gomme di na le lešata le legolo, di fetiša go betwa le go šikinyega, gomme di nyaka go lekanetšwa mo go nepagetšego (≈ ¼°). Ga di loketše di-drive tše di betwago kudu. Go di-centrifugal fan le di-pump, go tloša slip go oketša lebelo le maatla: lekola gape bogolo bja dipulley.

PU belt ye nkgokolo (Polycord)

Thapo ye nkgokolo ya polyurethane, ye e tšhumišwago go ya ka botelele mošomong. Ke motheo wa di-packline tša dienywa: di-singulator, di-roller table, di-sizer drive le di-conveyor tše bofefo. E hwetšwa e boreledi goba e le makgwakgwa, le ka di-diameter le bothata bjo bo fapanego.

Botelele bo bewa ka go namologa: belt ye nkgokolo gantši e segwa e kopana ka diphesente tše mmalwa go feta tsela ye e e sepelago; latela palo ya go namologa ya modiri go diameter le bothata.
Tšhuma ka blade ya go tšhuma le clamp ye e swanetšego gore kopano e be thwi e sa fokotšege. Go robega mo gontši ga dibelt tše nkgokolo go bakwa ke go tšhuma gabe.

Dibelt tše phaphathi le di-conveyor belt

Di-flat belt (tše di dirilwego ka polyamide goba elastomer) di šoma gabotse ka lebelo le legolo go dipulley tše di kobilego: di-tangential drive go di-textile mill, di-folder-gluer, go phuthela. Di-conveyor belt tše bofefo di rwala setšweletšwa go di-line tša go phuthela le dijo, di-packhouse le di-warehouse; hlaloša bophara, botelele, bokagodimo (bo boreledi, bo swarago, bja dijo), mohuta wa kopano (finger splice, di-fastener) le carcass.
