2、, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers warping heads used withwindlass, winch, and capstan

Dimensions, Mass, and Permissible Variations7.1 Principal dimensions, tolerances, and str
34、ength require-ments for Types I and II are shown in Fig. 1 and Fig. 2,respectively. These requirements are considered standard andwill govern unless special features are required and described(see 5.1.8).7.2 Commonly acceptable warping head sizes for variousfiber ropes are shown in Table 1 for gener
35、al guidance only. TheTABLE 1 Warping Head Size and Suggested Rope SizeNOTE 1The following table is provided for guidance subject tovariations in breaking strengths and friction characteristics of specificropes.

38、rope is acceptedpractice. Some synthetic fiber ropes, because of reducedfriction, require additional wraps. The equivalent sizes ofsynthetic fiber ropes shown in Table 1 are reduced on the basisof breaking strength and provide additional space on the barrelfor increased wraps.7.3 The strength of the
39、 barrel, flanges, webs, and dia-phragms shall withstand the maximum rope pull shown in Fig.1 and Fig. 2, applied tangent to the barrel, normal to the shaft,at the midpoint of the barrel, and wrapped around the barrel,with the combined stress not exceeding 75 % of the tensileyield point of the materi
40、al. Compressive forces on the barrel,torsional shear forces between hub and barrel, and the wedgingforces against the flanges, shall be considered. This require-ment does not imply a similar requirement for drive horse-power or brake capacity in the drive unit.8. Workmanship, Finish, and Appearance8
41、.1 Welds shall be extended around ends of members and befree of pockets and irregularities that would tend to trap water.8.2 Welds shall be ground flush to match the surroundingsurface in areas of rope contact.8.3 Component parts, formed by rolling or flanging, shall bevisually examined during fabri
42、cation to ensure freedom fromcracks.8.4 Castings shall be smooth, of fine grain, and free ofcracks, hot tears, and blow holes, detrimental to end use.8.5 Castings shall have all flash material, vents, and gatesremoved and ground flush to match the surrounding surfaces.8.6 Weldments and castings shal
43、l be free of sharp edges andburrs that could cut or snag fiber rope coming in contact withany accessible portion of the rotating warping head.8.7 Rope contact surfaces of Grades 3 and 4 warping headsshall be finished to an average surface roughness of 125 to 160in. (3175 to 4064 mm) in accordance wi
44、th ANSI StandardASA B46.1.NOTE 1Local flaws (holes) no larger than316 in. (4.7 mm) indiameter are acceptable when they have no sharp edges or burrs thatwould cut fiber rope, providing the total area of flaws (holes) does notexceed 5 % of the total rope contact surface.8.8 Weldments and castings shal
45、l be cleaned by sandblasting, shot blast, or equivalent methods to remove all loosescale or slag.9. Inspection9.1 The completed warping head shall be visually inspectedfor workmanship, dimensions, surface hardness (when appli-cable), finish and appearance, after cleaning.10. Product Marking10.1 Ship
46、pingEach warping head, when furnished as aseparate component, shall be marked with the ASTM standarddesignation, type and grade, purchase order, and item number.Product marking shall be by paint or weatherproof tag.11. Packaging and Package Marking11.1 Warping heads, when furnished as a separate com
47、po-nent, shall be crated, skidded, or attached to a pallet in amanner acceptable for handling by common carrier. Whenwarping head is furnished with machined bore or hub, ma-chined surfaces shall be protected against corrosion in openweather storage for a period of at least one year.12. Keywords12.1
