11、OREWORDThis Standard is a consolidation of two ASME standards,ASME B29.11M-1994(CombinationChains,Attachments,and Sprocket Teeth)and ASME B29.14M-1996(H Type Mill Chains,Attachments,and Sprocket Teeth).These two standards were combined into one because of thesimilarity of construction and the unusua
12、l applications for the two types of chains.B29.11M Combination Chains,Attachments,and Sprocket TeethIn 1886 a patent was granted for a chain comprised of cast metal block links,fitted with bronzebushings,and connected with wrought steel sidebars and removable pins.This chain was theforerunner of the
13、 present combination chain(B29.11M),later placed on the market around 1900.Many sizes and types of combination chains were developed and marketed in the next severalyears.During World War I,the War Industries Board insisted that chain manufacture be confined tothe necessary sizes.This caused elimina
14、tion of several types and sizes,and planted the seed forfuture standardization.Following World War I,the Malleable Chain Manufacturers Institute wasformed,and this group did considerable work on standardization of chain and sprocket dimen-sions for combination chains of the more popular sizes.There
15、were still dimensional variationsthat would not permit universal intercoupling of chains of different manufacture,necessitatingrepairs made with chains of the original manufacturer.The ASCMA(now the American Chain Association),recognizing the need for a completestandard providing intercoupling and d
16、irect replacement of chains of different manufacture,established this Standard utilizing the minimum number of chains to meet requirements ofindustry for the chains widely used in conveyor and elevator applications.To facilitate the use of this Standard in the international market,the metric equivalents of alldimensions are given.This Standard was presented to the USASI(now the American National Standards Institute)B29 Committee in December 1963 and,upon approval by the USASI on May 24,1968,was
