13、ring Drawing and Related Documentation Practices, Mechanical Spring Representation, ANSI Y14.13M-1981.) Subcommittee 13 of the American National Standards Committee Y14, Standards for Engineering Drawing and Related Documentation Practices, was organized prior to 1963 for the purpose of determining
14、the need for a national drawing standard on mechanical springs. At that time, in addition to various proprietary industry design and drafting documents, two national standards existed: MIL-STD-29A and Section C3 of the SAE Aerospace-Automotive Drawing Standards. Both of these standards were replete
15、with design information. At the May 1972 meeting of the Y14 Committee, it was agreed that Subcommittee 13 should be reorganized and a new effort made to develop a national drawing standard for mechanical springs. This effort was made to first determine whether a standard was actually needed. The inv
16、estigation showed that MIL-STD-29A was being used in militasr programs requiring acquisition of springs from industry and showed that the Spring Manufacturers Institute and spring industry supported the need for establishing a standard for expressing functional requirements on engineering drawings (
17、corresponding to the existant manufacturing standard), Consequently, a first draft was produced using MIL-STD-29A as the basis and attempting to eliminate design information. Circulation of the first draft to various individuals in the manufacturing as well as the drawing preparation category occurr
18、ed late in February 1978. The comments that were received were considered in preparing subsequent drafts. This Standard does not presume to restrict drawing content to only that which appears herein. Drawings must convey design intent and be complete enough that a designated part can be produced fro
19、m them. This Standard does not intend to suggest that the types of springs presented herein are more important than those omitted. The choice of which types of springs to present was made on the basis of those types found in MILSTD-29A. This document has been prepared in a manner that is independent
20、 of the system of measure- ment to be used. Traditional terms (such as “load”) have been changed to technically correct terms (such as “force”). Suggestions for improvement of this Standard will be welcomed. They should be sent to the American National Standards Institute, 1430 Broadway, New York, N
21、ew York 10018. This Standard was approved by the American National Standards Institute on October 30, 1981. - iii O Copyright ASME International Provided by IHS under license with ASMENot for ResaleNo reproduction or networking permitted without license from IHS-,-ASME Y34.33M 83 AMERICAN NATIONAL S

30、plicable to all spring drawings are material specifications and inspection notes. 6.2.1 Material Specif cations. Material specifica- tions are designated in the space provided on the drawing.

FOR 6.4 Helical Compression Springs A compression spring is an open coil helical spring that offers resistance to a compressive force applied axially. Compression springs are generally cylindrical in form, although other form
37、s are available (such as conical, tapered, concave, or convex). Wire of circular cross section is normally used. However, where there is a design advantage, wire of square or rectangular cross section should be specified. Figure 1 illustrates several forms of helical compression springs. Copyright A

Gu
39、idelines which provide for helical compression spring design requirements on an en- gineering drawing (dimensionally and physically) and which allow maximum latitude in manufacturing are categorized as follows. (a) No Force Specqied. The design activity ac- cepts the responsibility for the capabilit
40、y of the spring. The manufacturer must furnish a spring that meets the dimensional data specified. The free length, the coil diameter, and the total number of coils are specified, each with a tolerance. The tolerance on the wire diameter conforms to the governing mate- rial specification. See Fig. 2
41、. (b) One Force Specified. This category has ap- plication where the spring is required to resist a force, within a specified tolerance, preferably at the initial assembled length. The spring is not normally sub- jected to further deflection in operation. The manu- facturer is required to meet physi
42、cal requirements, but the free length and the total number of coils are not restricted. The tolerance on the wire diameter conforms to the governing material specification and the specific coil diameter is dependent upon spring function. See Fig. 3. (c) Two Forces Specqied. This category has applica
43、tion where the spring is required to resist a force, within a specified tolerance, at each end of two definite compressed lengths, normally at the initial and the fial operating positions ir. the assembly. The manufacturer is required to meet the physical requirements, other spring characteristics b
44、eing designated as described in (b) above. See Fig. 4. (d) Spring Rate Specgied. This category has application in assemblies in which the spring rate is the most significant characteristic, for example, in calibrated scales. Because spring rate is not perfectly linear, the two lengths between which
45、the rate is to be checked should be specified. The manufacturer is required to meet a prescribed spring rate, but the free length and the total number of coils are permitted to vary. The tolerance on the wire diameter conforms to the governing material specification and the specific coil diameter is
46、 dependent upon the spring function. Additionally, where closer control of the force to be resisted at the initial assembled length is desired, one force, with a tolerance to be developed at the as- sembled length, should be specified. See Fig. 5. ANSI Y14.13M-1981 6.4.1.1 Coil Diameter. Depending u
47、pon the application of the spring, specify the following as required: (a) TO WORK OVER-MAX. DIAMETER ROD (b) TO WORK IN-MIN. DIAMETER BORE (c) I.D. (with tolerance) (d) O.D. (with tolerance) 6.4.1.2 Direction of Helix. Where governed by design requirements, specify the direction of helix as “LEFT HA
48、ND” (LH), or “RIGHT HA” (RH), as applicable; otherwise, specify the direction of helix as “OPTIONAL.” In most cases, the hand is not impor- tant except where a plug is screwed into the end or where one spring fits inside another. In the case of the latter, one spring should be designated left hand a
49、nd the other spring right hand. 6.4.1.3 Type of Ends. The type of ends having application to helical compression springs are illus- trated in Fig. 6. Specify the type of ends on the draw- ing. Where necessary, the ends should be dimen- sioned. 6.4.1.4 Solid Length. The maximum solid length shall be specified for any spring category where this parameter is essential to design require- ments. However, solid length should be omitted wherever practicable. Except where necessary to satisfy functio
