10、f Mechanical EngineersThree Park Avenue, New York, NY 10016-5990Copyright 2001 byTHE AMERICAN SOCIETY OF MECHANICAL ENGINEERSAll Rights ReservedPrinted in U.S.A.FOREWORDThe need for a standard covering machine pins was recognized by industry as far backas March, 1926, when the Sectional Committee on
11、 the Standardization of Machine Pinswas organized under the procedure of the American Standards Association (later the UnitedStates of America Standards Institute and as of October 6, 1969, the American NationalStandards Institute, Inc.), with the Society of Automotive Engineers and the AmericanSoci
12、ety of Mechanical Engineers as joint sponsors.For the next year or two, an effort was made via correspondance to develop a basis onwhich a standard for straight, taper, split, and dowel pins might be established. Thiscorrespondence developed a distinct difference of opinion on the part of the manufa
13、cturersand users of taper machine pins, which fact seemed to discourage the members of thecommittee from attempting standardization on any of the types of pins within its scope.The sponsor organizations made frequent efforts to revive this project through letters andthe distribution of technical lit
14、erature on this general subject, without avail.In December, 1941, in its periodic review of standards projects for which the Societyis sponsor, the ASME Standardization Committee decided that there was little hope forreviving this project and voted, subject to acceptance by the sponsors, to suggest
15、to theASA the transfer of this project to Sectional Commitee B5 on the Standardization of SmallTools and Machine Tool Elements. The sponsors agreed and on July 7, 1942, the ASAsanctioned this action and Sectional Committee B43 was discharged and the project wasofficially transferred to Sectional Com
16、mittee B5.At its meeting in December, 1942, Sectional Committee B5 voted to enlarge its scopeto include machine pins. Technical Committee No. 23 was subsequently established andcharged with the responsibility for technical content of standards covering machine pins.This group held its first meeting
17、on November 30, 1943, at which time a Subgroup onCorrelation and Recommendations was appointed and it was voted to include clevis pinsin addition to the other pin types already under consideration. Several drafts were preparedby the subgroup, distributed for critical comment to users, manufacturers,
18、 and generalinterests, and revised and resubmitted for comments. This action finally resulted in acceptanceby Technical Committee 23 of a draft dated November, 1945, which was duplicated inprinters proof form, under a date of October, 1946, and distributed to the members ofSectional Committee B5 for
19、 letter ballot approval. Subsequent to the approval of the SectionalCommittee, the proposal was next approved by the sponsor bodies, and presented to theAmerican Standards Association for approval as an American Standard. This designationwas granted on July 7, 1947.Following the issuance of the stan
20、dard, it became apparent that the table on cotter pinsneeded revision. Accordingly, in 1953 a proposed revision was submitted to the SectionalCommittee. After attaining Sectional Committee and sponsor approval, this revision wasapproved by the American Standards Association on July 9, 1954 as ASA B5
21、.20-1954.In 1956 and 1957, in response to requests from industry, extensive changes wereincorporated into a proposed revision. These included revisions to chamfer values andtolerances on straight pins and unhardened ground dowel pins; revisions to under head tohole, pin end dimensions, and hole size
22、s tolerances on clevis pins; addition of chisel pointto cotter pin end styles and the incorporation of coverage on grooved pins. FollowingiiiSectional Committee and sponsor approvals, this revision was adopted by the AmericanStandards Association on March 25, 1958, as ASA B5.20-1958.Late in 1961, Se
23、ctional Committee B5 suggested that Sectional Committee B18 on thestandardization of bolts, nuts, rivets, screws, and similar fasteners assume jurisdiction overstandards for pins. Recognizing that the bulk of the products covered in the ASA B5.20standards were fastener rather than machine oriented,
24、this recommendation was supportedby the B18 Committee and officially endorsed by the sponsor organizations. Consequently,at the September 14, 1962 meeting of this Committee it was decreed that Subcommittee231should be formed to undertake a review and updating of the pin standard.At the initial meeti
25、ng of Subcommittee 23 held on June 3, 1964, it was decided to addstandards for spring pins (inch series) and to establish seven subgroups, each of whichwould have technical responsibility for specific pin products, and to publish respectiveproducts under separate cover as projects were completed.Ove
26、r the ensuing several years, work by Subgroups 2, 3, 4, 5, and 6 culminated in thedevelopment of a proposal for revision of the standards covering taper, dowel, straight, andgrooved pins and including coverage of spring pins (inch series) which was approved byletter ballot of Subcommittee 8 on Febru
27、ary 24, 1977. Subsequent to acceptance by AmericanNational Standards Committee B18 and the sponsor organizations, this document was dulysubmitted to the American National Standards Institute for approval as an American NationalStandard. This was granted on April 5, 1978 and the standard was publishe
28、d under thedesignation ANSI B18.8.2, superseding in part the coverage provided in ASA B5.20-1958.ASME B18.8.2 was revised and approved by ANSI on April 5, 1994.In response to increased user demand as well as to the federally endorsed metricationprogram, a metric standard was developed for spring pin
29、s coiled type, spring pins slotted, machine dowel pins hardened ground, and grooved pins.In December 1988, Subcommittee 8 proposed B18.8.3M, covering spring pins, coiledtype, metric series for B18 Main Committee approval.In May 1993, Subcommittee 8 proposed B18.8.4M, covering spring pins, slotted, m
30、etricseries for B18 Main Committee approval.In May 1993, Subcommittee 8 proposed B18.8.5M, covering hardened ground machinedowel pins, metric series, for B18 Main Committee approval.In April 1997, Subcommittee 8 submitted proposed standard B18.8.9M, covering groovedpins, metric series, for B18 Main
31、Committee approval.In April 1999, Subcommittee 8 proposed B18.8.3M, B18.8.4M, B18.8.5M, and B18.8.9Mbe consolidated into B18.8.100M.ASME B18.8.100M-2000 was approved by the American National Standards Institute(ANSI) on June 22, 2000.1As of April 1, 1966, Subcommittee 23 was redesignated Subcommitte

41、D TYPE(METRIC SERIES)1 INTRODUCTORY NOTES1.1 Scope1.1.1 This Standard covers the dimensional andgeneral data for coiled spring pins recognized as Ameri-can National Standard, which are widely used in generalindustrial applications.1.1.2 The inclusion of dimensional data in thisStandard is not intend
42、ed to imply that all of the productsdescribed are stock production sizes. Consumers shouldconsult with suppliers concerning the availability ofthe product.1.2 DescriptionCoiled spring pins shall have straight cylindricalsides with both ends chamfered. They are available instandard duty, heavy duty,
43、and light duty to suit variousdesign requirements. Coiled type spring pins have multi-ple walls, are spirally wrapped from strip stock to adiameter larger than basic, and are heat treated asnecessary or cold worked. Upon installation, the pindiameters contract and the spring reaction against theside
44、s of the hole tends to retain the pin. Dimensionsof coiled type spring pins are given in Table 1.1.3 DimensionsAll dimensions in this Standard are in millimetersunless otherwise noted.1.4 OptionsOptions, where specified, shall be at the discretionof the supplier, unless otherwise agreed upon by thes
45、upplier and purchaser.1.5 TerminologyFor definitions of terms relating to fasteners or compo-nent features thereof used in this Standard, refer toASME B18.12.21.6 Comparison With ISO 8748, ISO 8750,and ISO 87511.6.1 ISO 8748, ISO 8750, and ISO 8751 wereprepared by Technical Committee ISO/TC2 and pub

This Standard includes all three duties.1.6.3 At this time, all three ISO documents covercarbon steel only. This Standard covers the followingmaterials:(a) 10701095 carbon steel

48、e pin hardness in the three ISO documentsfor carbon steel is listed as 420 to 520 HV. ThisStandard lists the hardness for carbon steel and alloysteel as 420 to 545 HV.
