FOREWORD

[This Foreword is not part of American National Standa rd, Inverted Tooth (Si lent)

Chains and Sprockets, AN SI 829.2M-1982.1

Preparatory work during the late 1930’s and early 1940’s by the Silent Chain Division of the

Association of Roller and Silent Chain Manufacturers (ARSCM) (now the American Chain

Association) resulted in agreement on stand ardiz ation of silent chain primarily on the basis of

standardizedspro cket ooth design. Since individual chain man ufac turersemployed various

chain join t designs, it was agreed that stan dard s on chain detail wo uld be limite d to insure inter-

changeability of chains on sprockets ofany number of teeth. At a meeting of representatives of

all major American silent chain manu facturers in Septembe r 1944, unde r the auspices of the

ARSCM , recommend ed “Engineering S tand ards for Industrial Silent Chain and Sprock ets” were

agreed upon. Formulas for sprocket design were expan ded nto tables which were approved

andadoptedby he ARSCM in April 1945. Supplementary nformationonsprocket ooth

cutters was added and all of the data were incorporated in a comprehensive repor t, Industrial

Standards for Industrial Silent Chains, Sprock ets and Cutters. This report, with further refine-

ments by minor revisions in 1949 and 1950, was then submitted to the Sectional Committee for

review and approval as an American Stand ard.

The Sectional C omm ittee accepted the recommendation s with some minor revisions in 1950,

and referred it to TheAmerican Soci ety of Mechanical Engineers and the Society of Automo tive

Engineers for their approval as sponsors of the Comm ittee, and subsequen t transmission to th e

American S tand ards Association for final acceptance as an American Standar d. Afte r approval

by ASME and SAE, it was acceptedby ASA on Novem ber 9, 1950, as American Standard

B29.2.

In 1956, the Sectional Committee authorized

a

revision to the standard to bring it up to date .

The revised standard was approved by the Am erican Standards Association o n July 11 ,

1957.

This revision has been in use for man y years, and was reaffirmed by th e American National

Standards Institute on January 4 , 1971 . (ASA became ANSI in 1 969.)

In 1945, the formulation of a recommended standard for “small pitch” silent chain (pitch

sizes less than 3 / ~ n.) and sprocket tooth form became a matter of consideration by ARSCM’s

Silent Chain Division. As in the case of the larger chain series, th e objective was to provide

interchangeability of chains on sprockets, and th e development of recommended practices for

power transmission ratings and selection procedure. Afte r a num ber

of

years of usage as an

ARSCM Industrial Stand ard, the recomm endations became American Standard B29.9 in 1958.

Although it was originally anticipated that there might be a need for tw o

or

three pitch sizes of

the miniature silent chains, only one, the /1.5 in. size, has been developed.

The nformation whichhas heretofore beenpublished as B29.9 was incorporated in the

basic Silent Chain Standard, B29.2, as part of this present revision and mod ernization of both

documents.

This Standard was approved by the American N ational S tandard Institute December 21,1982.

CHAINS ANDSPROCKETS

SILENT CHAINS

1.1 Nomenclature

( a )

Silent chain is a series of toothed links alternately

assembled with pins or acombination of joint com-

ponents in such a way that the jointarticulates between

adjoining pitches.

As

shown in Fig. l .l(a )-1 , side guide

silent chain has guide links which straddle the sprocket

sides to con trol the chain laterally. As shown in Fig.

l.l(a )-2, center guide silent chain has guide links which

run within a circum ferential groove or grooves for lateral

control.

( b ) Typical Links. Since joint com ponents, connectors,

and offset sections vary with each manufacturer, these

items are no t included in this standardization. See Fig.

1 l(b)

for examples of typical

links.

1.2

General Configuration

Link contour may vary but must engage standard

sprocket teeth

so

that joint centers lie on sprocket

pitch circle.

(a ) in. Pitch ChainandLarger.

Chain widths equal

to, or exceeding,

2

times the pitch have center guides.

Narrower chains may be side guide or center guide.

Chain widths exceeding

16

times the pitch are not

recommended.

( b ) 3II6

in. Pitch Chain.

Chainmaybesideguide

or

center gu ide as indicated in Tables

1.8-1

and 1.8-2.

(c) Maximum chain width should be limited to ap-

proximately 8 times the pitch.

1.3 Numbering System

( a ) 318 in Pitch Chain and Larger. Two letters SC as a

prefm, o ne or two numerals indicating pitch in eighths

of an inch, and two or three num erals indicating nominal

chain width in quarters of

an

inch. Thus SC302 desig-

nates

a

silent chain,

3/8

in. pitch by l/2 in. nominal width,

and SC1012 designates a silent chain, 11/4 in. pitch by

3 in. nominal width.

( b ) 3/16 in. Pitch Chain.

Two letters SCas a prefix, a

zero followed by a numeral indicating pitch in sixteenths

of an inch, and two numerals indicating nominal width

of chain in thirty-seconds

of

an inch. Thus SC0309

designates a silent chain,

3/16

in. pitch by

9/32

in. nominal

width.

NOTE: Where links are all of equal thickness 0.030 in.

(0.76

mm), it is understood tha t the width ndication

also designates the otal number of links across the

width of the chain.

1.4

Tolerance

for

Chain

Length

( a ) 318 in. Pitch Chain and Larger.

Chains will be de-

signed and manufactured to fit gage sprockets. Tolerance

for chain length for new chains may beover nominal

length 0.030 in./ft (0.76 mm/ft), but must not be under-

length.

( b )

3 / 26

in. Pitch Chain. Chain length tolerance is 0.020

in./ft (0.5 1 mm /ft) over nominal length, but m ust no t be

underlength.

1.5

Measuring Loads

( a )

318 in.

Pitch Chain and Larger.

Chain should be

measured under load of 25 lb

X

pitch in inches X width

in inches

t 2 0

lb (0.1724

N

X

pitch in mm

X

width in

mm +89 N). Length measurements are to be taken over

a length of at least 12 in. (300 mm).

( b ) 3/16

in. Pitch Chain.

The measu ring load for 3/16 in.

pitch silent chain shall be approximately equal to

1

lb

(4.45 N) for each link in the total chain width, Le., the

load for SC 0315 would be 15 lb (67 N). Length mea-

surements are

to

be taken over a length of at least 12

in.

(300 mm).
