FOREWORD (This Foreword is not p
9、art of ASME B29.12M-1997.) Chains of the type covered by this Standard were introduced early in the 20th century. The chains met with considerable success on material conveyors and elevators, and manufacturers developed and marketed many sizes and types in the next several years. The American Sprock
10、et Chain Manufacturers Association (now the American Chain Association) recognized the need for standards which would provide for interchangeability by intercoupling chains of various manufacture. In November 1960, a working group of produc- ers of the bushed rollerless chains was formed to accompli
11、sh standardization. This Standard is the result of the work of that group. This Standard was presented to the USA (now ANSI) Standards Committee B29 on December 12, 1967, and, upon approval by the USA Standards Institute (now American National Standards Institute, Inc.), on October 18, 1968, was ado
12、pted and published. The 1974 revision included minor changes in metric units and the addition of caution notes to Table 1. To facilitate the use of this Standard in the international market, the metric equivalents of all dimensions are given. The current revision includes the addition of chain numbe
13、rs S-856, S-857, S-859, and S-864 and attachments K-24, K-3, K-35, K-44, and K-443 for these chains. Also added is minimum bolt hole diameter required for the bolt diameter for a particular attachment. The Minimum Ultimate Tensile Strength definition (para. 2.1) has also been modified. This revision
14、 was approved by the American National Standards Institute, Inc., on March 25, 1997. iii ASME STANDARDS COMMllTEE B29 Chains, Attachments, and Sprockets for Power Transmission and Conveying (The following is the roster of the Committee at the time of approval of this Standard.)

Maximum and minimum strand lengths for each chain are listed in Table 1. 2 GENERAL CHAIN PROPORTIONS AND DESIGNATIONS 2.4 Dimensions of Chain Links 2.1 Minimum U
23、ltimate Tensile Strength (M.U.T.S.) Minimum Ultimate Tensile Strength (M.U.T.S.) for chain covered by this Standard is the minimum force at which an unused, undamaged chain could fail when sub- jected to a single tensile loading test. WARNING: The Minimum Ultimate Tensile Strength is NOT a “work- in
24、g load!” The M.U.T.S. greatly exceeds the maximum force that may be safely applied to the chain. (a) Test Procedure: A tensile force is slowly applied, in uniaxial direction, to the ends of the chain sample. (b) The tensile test is a destructive test. Even though the chain may not visibly fail when
25、subjected to the “Minimum Ultimate Tensile Force,” it will have been damaged and will be unfit for service! To assure interchangeability of either block links or connecting links as produced by different makers of chain, standard maximum and minimum dimensions are adopted. They are not actual dimens
26、ions used in manufacturing but limiting dimensions, maximum or minimum, required to assure the desired interchange- ability. In addition to the sprocket tooth form in this Standard, these chains can operate over sprockets de- signed to ASME B29.11M-1994 or combination chains, provided consideration
27、is given to strength and addi- tional sidebar clearance required for chain sizes S 11 1 and S 150. Dimensions are given in a decimal inch system essen- tially in accordance with ANSI B87.1-1965. The metric equivalent dimensions are for reference only in ANSI 2210.1-1972. 1 ASME B29.12M-1997 STEEL BU
