The work of preparing International Standards is normally carried out through ISO tech
13、nical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
14、 with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of
15、 the member bodies casting a vote. International Standard ISO10792-2 was prepared by Technical Committee ISO/TC20, Aircraft and space vehicles, Subcommittee SC 15, Airframe bearings. ISO 10792 consists of the following parts, under the general title Aerospace Airframe spherical plain bearings in cor
16、rosion-resisting steel with self-lubricating liner: Part 1: Metric series; Part 2: Inch series; Part 3: Technical specification. Annex A of this part of ISO10792 is for information only.iv blankISO10792-2:1995(E) BSI 01-2000 1 1 Scope This part of ISO10792 specifies the characteristics of spherical
17、plain bearings in corrosion-resisting steel with self-lubricating liner, narrow and wide series, for elevated loads at ambient temperature, for use in fixed or moving parts of the aircraft structure and control mechanisms at temperatures of55 C to+163 C. It is applicable to self-lubricating spherica
18、l plain bearings (without rolling elements) consisting of an outer ring having a concave sphered sliding contact surface with self-lubricating liner and inner ring having a matched convex sphered sliding contact surface. At the time that this part of ISO10792 was developed, airframe spherical plain
19、bearings with dimensions originally specified in Imperial units were dominant in world application. For this part of ISO10792, the dimensions of these bearings have been converted into metric units with the original characteristics given inAnnex A for information only. For new applications, the use
20、of the bearings specified in ISO10792-1 is recommended. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO10792.
