ANSI #40 thiab ISO 08B Ob leeg 1/2 Nti Pitch - Thiab Lawv Tsis Hloov
Transmission chain thiab matched sprockets
Lub hom phiaj lo lus tseem ceeb:ANSI vs ISO cov menyuam saw
Secondary:08B vs 40 saw, DIN 8187 cov menyuam saw, cov menyuam saw loj daim ntawv
Meta piav qhia:ANSI #40 thiab ISO 08B qhia 12.70 hli suab tab sis txawv ntawm cov menyuam txoj kab uas hla thiab sab hauv dav. Tag nrho qhov ntev ntawm lub rooj rau ob qho tib si qauv thiab yog vim li cas kev hloov pauv puas sprockets.
Tus neeg yuav khoom xaj "ib nrab-inch pitch chain." Tus neeg xa khoom nkoj 08B. Lub tshuab tau tsim nyob ib ncig ntawm # 40 sprockets. Txhua yam ntsuas 12.70 mm suab, yog li nws mus.
Peb lub lis piam tom qab cov hniav sprocket tau hnav rau hauv hooks thiab cov saw hlau dhia.
Ob leeg chains yog tiag tiag 12.70 mm suab. Ob leeg haum rau ntawm ncej. Thiab lawv tsis tuaj yeem hloov pauv tau, vim lub suab tsuas yog ib qho ntawm plaub qhov loj me uas yuav tsum sib phim.
Ob tus qauv
ANSI / ASME B29.1yog Asmeskas tus qauv, qhov ntau thiab tsawg los ntawm tus lej: # 25, # 35, # 40, # 50, # 60, # 80 thiab siab dua. Tus lej yog lub suab hauv yim ntawm ib nti - #40 yog 4/8", #80 yog 8/8".
ISO 606 / DIN 8187 Cov Ntawv Pov Thawjyog European B-series, xaiv 04B, 05B, 06B, 08B, 10B, 12B, 16B, 20B, 24B. Ntawm no tus lej yog suab hauv kaum rau ntawm ib nti - 08B yog 8/16"=1/2".
Ob leeg tuaj txog ntawm 1/2 nti. Lawv tau txais nrog sib txawv internal proportions.

Plaub qhov ntev. Ib qhov sib tw.
Qhov sib txawv ntawm cov menyuam txoj kab uas hla yog ib qho uas wrecks sprockets. Ib tug sprocket hniav hnab yog txiav rau lub rooj rau ib tug tshwj xeeb cov menyuam txoj kab uas hla. Muab cov menyuam 8.51 hli tso rau hauv lub hnab tsho profiled rau 7.95 mm thiab cov menyuam caij siab rau ntawm tus hniav flank es tsis txhob zaum hauv lub hauv paus. Kev sib cuag thaj chaw tawg mus rau ib txoj kab, tiv tauj kev ntxhov siab ntau ntxiv, thiab cov hniav hnav mus rau hauv qhov profile hauv lub lis piam.
Qhov dav sab hauv qhov sib txawv ua haujlwm rau lwm txoj hauv kev - 08B yog 0.10 hli nqaim, yog li cov saw hlau haum tshaj li # 40 sprocket nrog me ntsis clearance dua li qhov xav tau, uas tseem ceeb rau kev sib haum xeeb thiab kev nkag mus rau roj nplua nyeem.
A-series tsis meej pem
Muaj ib tsev neeg thib peb uas ua rau qhov no tsis zoo: ISO 606 kuj txhais ib qhoA -series- 08A, 10A, 12A, 16A - uasuasib haum rau ANSI qhov ntau thiab tsawg. 08A qhov sib tw #40, 10A qhov sib tw #50, 12A qhov sib tw #60, 16A sib tw #80.
Yog li hauv ISO nomenclature:
08A= ANSI #40 qhov ntev
08B= British/European 1/2" saw, txawv qhov ntev
Ib tsab ntawv. Cov saw sib txawv kiag li. Yog tias tus neeg muag khoom hais "08 saw" yam tsis muaj tsab ntawv, nug.
Vim li cas 08B thiaj li muaj zog
Saib dua: 18,200 N piv rau 14,800 N, hauv tib lub suab. B-series ua tiav qhov ntawd nrog tus pin loj dua (4.45 vs 3.96 mm) thiab cov menyuam loj dua.
Daim duab 2. ANSI B29.1 yam tsawg kawg nkaus tensile zog los ntawm qhov loj me.
Qhov ntawd tsis yog qhov tau txais dawb. Cov pins loj dua txhais tau tias cov khoom siv ntau dua hauv kev hnav khaub ncaws thiab ntau dua - muaj peev xwm sib koom ua ke, tab sis B- cov saw hlau ntawm tib lub suab hnyav dua thiab muaj cov yam ntxwv sib txawv. Ob tus qauv sawv cev sib txawv engineering cuam tshuam los ntawm kev lag luam sib txawv, tsis zoo dua thiab tsis zoo dua ntawm tib yam.
Multi-strand: transverse pitch tseem ceeb heev

Ob qhov kev soj ntsuam muaj txiaj ntsig.
Duplex tensile yog raws nraim 2 × simplex thiab triplex yog raws nraim 3 × hauv cov duab luam tawm no. Hauv kev xyaum, kev sib faib ntawm cov strands yeej tsis zoo tag nrho - misalignment thiab manufacturing variation txhais tau tias ib txoj hlua nqa ntau dua. Tsis txhob tsim kom muaj ntau yam tsis muaj paj.
Thiab ib tug duplex sprocket yuav tsum phim ob lub saw lojthiablub transverse suab. A # 40 duplex sprocket yog txiav rau 14.38 hli strand spacing; ib qho 08B duplex sprocket raug txiav rau nws tus kheej tus nqi. Lwm txoj hauv kev uas ob tus qauv tsis hloov pauv.
Yam tsawg kawg tensile tsis yog ib qho kev ua haujlwm
Cov duab tensile saum toj no yogyam tsawg kawg nkaus tensile zog- lub load uas cov saw tawg nyob rau hauv ib tug rub. Lawv tsis ua haujlwm loads.
Kev sib raug zoo los ntawm cov ntaub ntawv ANSI luam tawm: tus qauv-series yam tsawg kawg nkaus ua raws li kwv yees li 12,500 × pitch² (pitch in inches). Kos nws - #40: 12,500 × 0.25=3,125 lb. #80: 12,500 × 1.0=12,500 lb. #160: 12,500 × 4.0=50,000 lb. Cov mis tuav hla cov koob.
Ob qho laj thawj tsis txhob loj rau UTS:
Kev qaug zog.Chain kev khiav hauj lwm ntawm ib feem ntawm qhov kawg lub zog tseem ua tsis tau los ntawm phaj qaug zog tom qab txaus cycles. Kev qaug zog txwv yog deb tshaj qhov kawg.
Dynamic loading.Chordal action, shock loads, thiab acceleration tag nrho ntxiv rau qhov nro tsis tu ncua. Cov ntaub ntawv luam tawm kuj qhia tau hais tias raugnruab nrabtensile khiav zoo tshaj qhov tsawg kawg nkaus - #40 nyob ib ncig ntawm 4,188 lb nruab nrab tiv thaiv 3,125 lb yam tsawg kawg nkaus - uas ntxias tib neeg los tsim kom ze rau qhov txwv. Tsim kom tsawg, tsis yog qhov nruab nrab.
Txheeb xyuas cov saw tsis muaj cim
Thaum lub tshuab tuaj txog nrog cov saw thiab tsis muaj ntaub ntawv:
Ntsuas suabtshaj 10 lossis 12 qhov txuas thiab faib - qhov tseeb dua li ib qhov txuas, thiab nws kuj qhia txog hnav elongation.
Ntsuas cov menyuam txoj kab uas hlanrog calipers. Qhov no yog qhov kev ntxub ntxaug: ntawm 1/2 "pitch, 7.92-7.95 mm txhais tau tias ANSI #40, 8.51 mm txhais tau tias 08B.
Ntsuas qhov dav sab hauvnruab nrab ntawm daim phiaj.
Ntsuas tus pin diampom qhov twg.
Cov menyuam txoj kab uas hla ib leeg daws cov teeb meem feem ntau, vim tias qhov ntawd yog qhov uas ob tus qauv sib txawv feem ntau thiab nws yooj yim los ntsuas.
FAQ
Kuv puas tuaj yeem khiav 08B saw ntawm #40 sprockets thaum muaj xwm ceev?
Nws yuav tig. Cov rollers yuav tsis zaum zoo, hnav sprocket yuav nrawm nrawm, thiab koj yuav tau hloov cov sprockets es tsis yog cov saw hlau xwb. Txais tau raws li qhov chaw nres tsheb rau cov xuab moos, tsis yog lub lis piam.
Qhov twg muaj zog dua, #40 lossis 08B?
08B - 18,200 N tawm tsam 14,800 N, los ntawm tus pin loj thiab cov menyuam.
08A yog dab tsi?
ISO A-series sib npaug ntawm ANSI #40. Tib qhov ntev li #40. Tsis zoo li 08B.
Vim li cas #25 thiab #35 tsis muaj chais?
Lawv yog cov bushing chains. Nyob rau ntawm cov me me pitches ib tug nyias muaj nyias ib txoj kev, yog li cov saw articulates ntawm bushing ncaj qha. Qhov no yog vim li cas lawv "cov menyuam txoj kab uas hla" daim duab yog bushing OD.
Puas yog #41 pheej yig dua #40?
Tsis yog - nws yog ib qho sib dua - txoj haujlwm saw nrog cov phaj nqaim thiab kwv yees li ib nrab ntawm lub zog tensile. Tib lub suab, cov chav kawm sib txawv.
Puas yog duplex chains ob zaug muaj zog li simplex?
Cov kev ntsuam xyuas luam tawm tau hais raws nraim 2 ×, tab sis kev sib koom thauj khoom tiag tiag ntawm cov hlua nyob ntawm kev sib haum xeeb thiab kev tsim khoom ntev. Khaws cov npoo.
Tianjin OuNaiDa Transmissions Technology manufactures kis tau tus mob saw thiab matched sprockets rau ob qho tib si ANSI B29.1 thiab ISO 606 / DIN 8187. Yog hais tias koj tsis paub meej uas tus qauv koj siv lub tshuab, xa peb cov menyuam txoj kab uas hla thiab puab dav thiab peb yuav txheeb xyuas nws.
