14、 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 committee has been established has the right to be represented on that committee. International organizations, governmental and non-
15、governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part
16、3. The main task of technical committees is to prepare International Standards. 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 least 75 % of the member bodies casting a
17、 vote. Attention is drawn to the possibility that some of the elements of this part of ISO 8579 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8579-1 was prepared by Technical Committee ISO/TC 60, Gears. This second edition c
18、ancels and replaces the first edition (ISO 8579-1:1993), which has been technically revised. ISO 8579 consists of the following parts, under the general title Acceptance code for gear units: Part 1: Test code for airborne sound Part 2: Determination of mechanical vibrations of gear units during acce

BS ISO 85791:2002 iv Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 04:28:16 GMT+00:00 2006, Uncontrolled Copy, (c) BSI IS-9758 O1:(2002)E I SO 2002 All irthgs ersedevr v Introduction The sound emitted by a
20、gear unit or gearmotor can be radiated by the casing of the gear unit, the driving system (e.g. motor, coupling, another gear unit), and the connected structures included in the gear-drive system. On-site and on the shop test stand, the perceived sound can be significantly increased by reverberation
21、 effects or by the radiation of extraneous sources. Depending on the type of gear unit or gearmotor, as well as on the requirement of the purchaser, it may be necessary for the manufacturer or supplier to know a) the sound emitted by the gear unit, excluding the sound from the driver/motor, driven s
22、ystem and transmission elements, b) the sound emitted by the gearmotor, including the motor and the transmission elements, c) the sound emitted by subsystems or auxiliaries, for example, the lubrication system, and d) the sound emitted by each of those elements in respect of a given requirement, or
23、in view of an efficient sound-proofing of the installation. This part of ISO 8759 describes methods for the determination of the sound emitted by a gear unit alone, a gearmotor or a gear-drive system. Sound emission is expressed in terms of the sound power level of the transmission system and the em
24、ission sound pressure level at the relevant work station (see 6.2). Annex A provides examples of practical microphone positions on the measurement plane for different gear types and sizes. Annex B gives typical sound-pressure and sound power levels for different gear types and sizes. Annex C, develo
