ASME B29.15M:1997 pdf download STEEL ROLLER TYPE CONVEYOR CHAINS ATTACHMENTS, AND SPROCKET TEETH
1 DEFINITIONS
M.U.T.S.. Minimum Ultimate Tensile Strength,theminimum force at which an unused, undamaged chaincould fail when subjccted to a single tensile loading test.steel roller type conveyor chains; a series of rollerlinks having steel bushings with rollers to contactthe sprocket teeth, alternating with links comprised ofsidebars and pins, which articulate in the steel bushingsof the roller link (see Fig.I).
2 GENERAL CHAIN PROPORTIONS ANDDESIGNATIONS
2.1 M,U.T.S
(a) M.U.T.S.is not a working load. The MU.T.Sgrcatly excceds the maximum force that may be applicdto the chain.
(b) Test Procedure: A tensile force is slowly applied, in a uniaxial direction, to the ends of the chainsample.
(c) The tensile test is a destructive test. Even thoughthe chain may not visibly fail when subjected to theMinimumUltimate Tensile Force,it will have beendamaged and will be unfit for service.Pins and bushings are fixed in the sidebar pitch holesby either press fits and/or mechanical locks, such asflats, to prevent rotation of the pins and bushings inthe sidebar pitch holes.
2.2 Measuring Load
The measuring load in pounds or newtons, listed inTable l. is the load under which a dry or lightlylubricated chain should be measured for length.
2.3 Strand Length Tolerance
New chains under measuring load may be over thetheoretical length up to 0.38 in.in120 in.(9.7 min 3048 mm),butmust not be under the theoreticallength.Maximum and minimum strand lengths for eachchain are listed in Table l.
3 DIMENSIONS OF CHAIN LINKS
To assure interchangeability of links as produced bythe different makers of chain.standard maximum andminimum dimensions are listed in Tables 2 and 3They are not actual dimensions used in manufacturing.but limiting dimensions,maximum or minimum，required to assure the desired interchangeability. (Themetric equivalent dimensions are for reference only.)Dimensions are shown in Fig.2.wherc
B= inside diameter of bushing
D = pin diameter
F = overall chain height
H = roller diameter
J= pin head to centerline
pin end to centerlineK=
P= assembled chain pitch (this is a theoreticalreference dimension used for basic calculations)
T sidebar thickness
U= sidebar height
V sidebar end clearance radius
W inside width of roller link
X outside width of roller link
Z= width between outer sidebars
4ATTACHMENT DIMENSIONS
See Tables 4,5，6,7,and 8 for various attachmenttype dimensions.
5 SPROCKET TOOTH FORM
5.1 Nomenclature
Figure 3 and other parts of this Standard utilize thefollowing nomenclature (see also Tables 9 and 10):C。= undersize compensation (typically 0.06 in..1.5 mm)
Cchain clearance circle
chain clearance circle factor (see Table 10) pitch line clearance
0= bottom diameter
5.2 Sprocket Tooth Form Data
The elements of a chain sprocket and the tooth formmay be determined by the following:
