Chains of the type covered by this Standard were introduced in the United States late in the 19th Century. As their popularity increased, the number of chains and manufacturers gr

10、ew. As one manufacturer developed a successful size chain, or family of chains, others soon duplicated it and a large number of chains came into being. In spite of efforts at standardization, the Corps of Engineers, United States Army, found during the Korean incident of 1950-53 that lack of adequat

11、e standardization of power transmission chains still resulted in the incapacitation of many cranes and shovels. For this reason, the Corps of Engineers requested the Society of Automotive Engineers to expand the scope of ASA Sectional Committee B29 to cover this group of chains. On May 13, 1956, the

12、 Corps of Engineers request was approved by the ASA B29 Committee and the ASA B29. I O Subcommittee was formed. Upon approval by the American Standards Association in April 1962, the first standard for ASA B29.10 chains and sprockets was published. The Standard described the physical dimensions of t

13、he chain components and sprockets, and defined the minimum static properties for the chains. In 1970, this Standard was revised to include Drive Selection information in a Supplementary Section and to convert fractions to decimal-inch, and include metric dimensions in SI Units. In September 1962, th

14、e Engineering Steel Chain Division of the ACA began a research program to develop ratings for the ANSI B29.10 chains. Capacity information on the smaller B29.1 chains already developed in research programs sponsored by the Roller Chain Division of the ACA was made available to the Engineering Steel

15、Chain Division. Member companies contributed information from their own research programs. Special dynamic test equipment was built to enable obtaining wear and capacity data on very large chains. The horsepower capacities published as supplementary information in this Standard resulted from this co

16、mbined research effort; they are considerably higher than previously accepted by the industry. At all speeds and for all sprocket sizes, the capabilities of ANSI B29.10 chain drives exceeded those previously accepted by the industry. This Standard was approved as an American National Standard on Dec

17、ember 27, 1972. The 1981 revision included updating to the current ANSI standards format covering chains and sprockets. In the process of updating, the supplemental information (Appendices A and B) was reviewed and found to be inadequate with respect to selection information. The information was inc

18、omplete and could result in an unsatisfactory selection. Chain standards generally contained only dimensional and strength information to allow chains to be intercoupled. Therefore, the horsepower capacity information was deleted. The American National Standards Institute approved that revision on A

19、pril 3, 1981. The 1991 revision added definitions for minimum ultimate strength (para. 2.2), measuring load (para. 2.3), and strand length tolerance (para. 2.4). M.U.T.S. values for chains 4020, 4824, and 5628 were increased. Other clarifications were made without changing the basic content. The 199

20、4 revision was approved by the American National Standards Institute on November 17, 1994. This 1997 revision of ASME B29.10M was approved by the American National Standards Institute on July 22, 1997. . 111 ASME COMMITTEE B29 Chains, Attachments, and Sprockets for Power Transmission and Conveying (

27、re free to turn on the bushings. Pins and bushings are fixed in their respective sidebar holes Fig. 1, sketches (a) and (b). In addition to press fits, other types of locks such as flats are sometimes used to prevent rotation of pins and bushings in their respective sidebar holes. 2 GENERAL CHAIN DE

28、SIGNATORS 2.1 Dimensions for Chain Links To assure interchangeability of links as produced by different makers of chain, standard maximum and minimum dimensions are adopted. They are not actual dimensions used in manufacturing, but limiting dimen- sions, maximum or minimum, required to assure the de

29、sired interchangeability. All dimensions are given in a decimal-inch system. The metric equivalent dimensions are for reference only. 2.2 Numbering System The standard chain numbers were based upon the inch system. The first two, or left hand digits in the chain designation denote the number of in.

30、in the pitch. The last two, or right hand digits, denote the number of 1/16 in. in the pin diameter. 2.3 Minimum Ultimate 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

31、when subjected to a single tensile loading test. WARNING: (a) The minimum ultimfe fende strength is not a “working load.” The M.U.T.S. greatly exceeds the maximum force that may be safely applied to the chain. (b) Test Procedure: A tensile force is slowly applied, in uniaxial direction, to the ends

32、of the chain sample. FIG. 1 HEAVY DUTY OFFSET SIDEBAR POWER TRANSMISSION ROLLER CHAINS (c) The tensile test is a destructive test. Even though the chain may not visibly fail when subjected to the “Minimum Ultimate Tensile Force,” it will have been damaged and will be unfit for service. CAUTION: This

33、 load is beyond the yield strength of the chain and would render the chain unsuitable for application. For application guidance, consult manufacturers catalogs or the American Chain Association Handbook, “Engineering Steel Chains for Conveyors, Elevators and Drives. 2.4 Measuring Load The measuring

34、load, in pounds (or kilonewtons) in Table 1, is the load under which a dry or lightly lubricated chain should be measured for length. ASME B29.1 OM-I 997 HEAVY DUTY OFFSET SIDEBAR POWER TRANSMISSION ROLLER CHAINS AND SPROCKET TEETH 2.5 Strand Length Tolerance The length of new chains subject to the

35、specified measuring load must fali within the plus and minus tolerances. Specific maximum and minimum strand lengths are shown in Table I, for each chain. 3 CHAIN ASSEMBLY See Fig. 2 and Tables 1, 2, and 3 4 SPROCKET TOOTH FORM See Fig. 3. 2 STD-ASME B27-LOM-ENGL 1997 E 0759b70 0587374 9bT = HEAVY D
