9、ASME B29.15M-1997.) Chains of the type covered by this Standard were introduced late in the nineteenth century. These chains met with considerable success on material conveyors and elevators. Manufacturers developed and marketed many sizes and types in the following years. In the 1920s, a working gr
10、oup from the producers of these chains was formed to standardize them. In 1972, a subcommittee of American National Standards Committee B29 was appointed with American Chain Association members from the engineering steel chain industry to expand and update the existing standards. The 1997 revision o
11、f this Standard incorporates the new definition of Minimum Ultimate Tensile Strength (M.U.T.S.), as well as updated sprocket symbols. This revision was approved by the American National Standards Institute on April 17, 1997. . 111 Intentionally left blank ASME STANDARDS COMMITTEE B29 Chains, Attachm

18、LER TYPE CONVEYOR CHAINS, ATTACHMENTS, 1 DEFINITIONS M. U.T.S.: Minimum Ultimate Tensile Strength, the minimum force at which an unused, undamaged chain could fail when subjected to a single tensile loading test. steel roller type conveyor chains: a series of roller links having steel bushings with
19、rollers to contact the sprocket teeth, alternating with links comprised of sidebars and pins, which articulate in the steel bushings of the roller link (see Fig. I). 2 GENERAL CHAIN PROPORTIONS AND DESIGNATIONS 2.1 M.U.T.S. (a) M.U.T.S. is not a working load. The M.U.T.S. greatly exceeds the maximum
20、 force that may be applied to the chain. (6) Test Procedure: A tensile force is slowly ap- plied, in a uniaxial direction, to the ends of the chain sample. (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
21、will have been damaged and will be unfit for service. Pins and bushings are fixed in the sidebar pitch holes by either press fits and/or mechanical locks, such as flats, to prevent rotation of the pins and bushings in the sidebar pitch holes. 2.2 Measuring Load The measuring load in pounds or newton
22、s, listed in Table 1, is the load under which a dry or lightly lubricated chain should be measured for length. 2.3 Strand Length Tolerance New chains under measuring load may be over the theoretical length up to 0.38 in. in 120 in. (9.7 mm in 3048 mm), but must not be under the theoretical length. M
23、aximum and minimum strand lengths for each chain are listed in Table I. AND SPROCKET TEETH 3 DIMENSIONS OF CHAIN LINKS To assure interchangeability of links as produced by the different makers of chain, standard maximum and minimum dimensions are listed in Tables 2 and 3. They are not actual dimensi
24、ons used in manufacturing, but limiting dimensions, maximum or minimum, re- quired to assure the desired interchangeability. (The metric equivalent dimensions are for reference only.)
