11、 ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical

12、 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 with the International Electrotechnical Commission (IEC) on all matters of elec

13、trotechnical 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 the member bodies casting a vote. International Standard ISO10792-1 was prepare

14、d by Technical Committee ISO/TC20, Aircraft and space vehicles, Subcommittee SC15, Airframe bearings. ISO 10792 consists of the following parts, under the general title Aerospace Airframe spherical plain bearings in corrosion-resisting steel with self-lubricating liner: Part 1: Metric series; Part 2

15、: Inch series; Part 3: Technical specification.iv blankISO10792-1:1995(E) BSI 11-1999 1 1 Scope This part of ISO10792 specifies the characteristics of spherical plain bearings in corrosion-resisting steel with self-lubricating liner, narrow and wide series, for elevated loads at ambient temperature,

16、 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 spherical plain bearings (without rolling elements) consisting of an outer ring having a concave sphered sliding contact surface with self-lubricat

17、ing liner and inner ring having a matched convex sphered sliding contact surface. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO10792. At the time of publication, the editions indicated were valid. Al

18、l standards are subject to revision, and parties to agreements based on this part of ISO10792 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
