1、ASME B29.300-1998AGRICULTURAL,DETACHABLE, AND PINTLECHAINS, ATTACHMENTS,AND SPROCKETSIncorporating ASME B29.6, B29.19, and B29.25AN AMERICAN NATIONAL STANDARD2%! ASME B29.19, Agricultural Roller Chains, Attachments, andSprockets; and ASME B29.25, Open Barrel Steel Pintle-Type Conveyor Chains, Attach

2、ments,and Sprockets. The new Standard was designated ASME B29.300, and entitled Agricultural,Detachable, and Pintle Chains, Attachments, and Sprockets. The new Standard has beenassigned to Subcommittee 4 Agricultural, Detachable, and Pintle Chains.The 1998 revisions of B29.6, B29.19, and B29.25 have

3、 been designed to integrate theagricultural-type chains found in each of these three Standards.B29.6 Steel Detachable Link Chains, Attachments, and SprocketsDetachable link power transmission chains have been used almost exclusively by agriculturalimplement manufacturers for power transmission and c

4、onveyors on manure spreaders, cornpickers, planters, hay rakes, potato diggers, elevators, and many other types of machines.The first steel detachable link chain was manufactured in 1897. This steel chain is madefrom special analysis steel strip, and is heat treated after forming to withstand wear a

5、ndprovide strength and toughness.Early in 1950, agricultural equipment manufacturers realized the need for a standard onsteel detachable link chains. In May 1951, a subcommittee of ASA Sectional CommitteeB29 was appointed with members from the agricultural implement industry and the steeldetachable

6、link chain industry to develop a standard for steel detachable link chains.During the 1960 revision, certain sizes of chains and attachments were deleted from theStandard with the intent of eliminating those of low popularity that were also closely similarto other existing sizes, thereby strengtheni

7、ng the Standard. In addition, several popularchains, attachments, and couplers were added. Some attachment designs were slightly revised.The coupler and coupler pin designs were revised to the currently more popular style,which allows any link to be used either right-handed or left-handed.This Stand

8、ard establishes, in the main, only those dimensions that will provide forinterchangeability of the chains in use without restricting the chain manufacturers in theiroverall design. The 1983 revision included the sprocket dimension controlling the surfacesthat must properly engage or clear the chain.

9、 The 1994 edition updated the Standard tothe current ANSI standards format and symbols covering chains. Number 45 and No. 67were deleted from the Standard since they are no longer manufactured. The definition ofMinimum Ultimate Tensile Strength (M.U.T.S.) was also updated.In this edition, the symbol

10、s and sprocket information sections were revised to provideconsistency throughout the consolidated B29.300 Standard.B29.19 Agricultural Roller Chains, Attachments, and SprocketsAgricultural replacement roller chains, introduced around 1956, provide implement engineerswith an upgrade from cast or ste

11、el detachable chains. These chains offer increased strengthand durability, and can be used with the same sprockets.iiiThe agricultural replacement roller chains are available in both drive series (A550 andA620) and conveyor series (CA550 and CA620). They have replaced No. 55 and No. 62detachable cha

12、ins in many applications and have found use in light-duty industrial conveyors.The Standard establishes essentially only those dimensions that will provide for interchange-ability of the chains in use without restricting the chain manufacturers in their overalldesigns.The B29 Committee agrees that t

13、he CA550 and CA620 chains may be used on No. 55and No. 62 detachable chain sprockets, respectively; however, the sprocket data includedin this Standard is for sprockets designed specifically for CA550 and CA620 chains. Thedifference in sprocket design is necessary because of the difference in roller

14、 diameters.The 1993 revision included updating to the current ANSI standards format and symbolscovering chains and sprockets. Minimum Ultimate Tensile Strength (M.U.T.S.) was redefined.The 1996 revision changed the name of the Standard from “A and CA550 and 620Roller Chains, Attachments, and Sprocke

15、ts” to “Agricultural Roller Chains, Attachments,and Sprockets.” Also, two new chains for both drive series (A555 and A557) and conveyorseries (CA555 and CA557), as well as several associated attachments, were added to theStandard.In this edition, the sprocket tooth form was modified to be identical

16、with the form usedin the other two chains.B29.25 Open Barrel Steel Pintle-Type Conveyor Chains, Attachments,and SprocketsThe open barrel steel pintle chain was originally developed in 1962 for the agriculturalimplement industry. The original sizes were developed to run on the same sprockets astheir

17、detachable chain counterparts of ANSI B29.6. In later years, sizes were developed toaccomodate industrial applications as well.The steel pintle chain is primarily used as a conveyor chain and, in limited use, as a powertransmission chain. Typical conveyor speeds are under 300 ft/min. Consult manufac

18、turers fordetails.The 1994 revision incorporated a restatement of the definition of Minimum UltimateTensile Strength (M.U.T.S.), and an addition of footnotes in Tables 3 and 4 regarding holesizes in certain attachments.In this edition, Tables 1 and 2 were combined for simplicity, and the sprocket to

19、othform was modified to be identical with the form used for the other two chains.Suggestions for improvement of these three Standards are welcome. They should be sentto The American Society of Mechanical Engineers; Secretary, B29 Main Committee; ThreePark Avenue; New York, NY 10016-5990.ASME B29.6,

41、undamaged chain could failwhen subjected to a single tensile loading test.WARNING: The Minimum Ultimate Tensile Strength is NOT a“working load.” The M.U.T.S. greatly exceeds the maximumforce that may be safely applied to the chain.(a) Test Procedure. A tensile force is slowly applied,in a uniaxial d

42、irection, to the ends of the chain sample.(b) The tensile test is a destructive test. Even thoughthe chain may not visibly fail when subjected to theM.U.T.S., it will have been damaged and will be untfor service.CAUTION: This load is beyond the yield strength of the chainand would render the chain u

43、nsuitable for application.3(c) For application guidance, consult the manufactur-ers catalogs or the American Chain Associationshandbook, Chains for Power Transmission and MaterialHandling.4 ATTACHMENTSSee Tables 1 through 11 of B29.6 for tolerancesand dimensions for the following attachments: plainl

Wearresistance

45、is frequently designed into the material ofthe tooth faces. Sprocket bodies are of many congura-tions (e.g., plate, arm, web, at, or dished). When hubscontaining the sprocket mounting bore are employed,they may project from either side or from both sidesof the sprocket body.This Standard covers only

46、 the dimensions controllingthe surfaces that must properly engage or clear thechain.Dimensions are given in a decimal inch system. Themetric dimensions given are recommended conversionsfrom the decimal inch system. In some cases theconversion is not exact; the decimal inch system istherefore to be t

47、aken as the base control dimension.Sprockets with standard tooth forms are capable oftransmitting chain loads in systems operating undera wide variety of conditions such as the followingcombination:(a) maximum peak tension in chain as great as 0.20of the ultimate breaking strength of the chain;(b) s

48、lack strand tensions as small as 0.25% of theworking tension in the chain;(c) friction between the chain and the sprocket toothfaces as low as 10%; and(d) the number of chain links in contact with theperiphery of the sprocket as few as 0.5 (N 1).STEEL DETACHABLE LINK CHAINS,ATTACHMENTS, AND SPROCKET
