The work of preparing International Standards is normally carried out through I

21、S0 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-governmental, in liaison with ISO, also take part in the work. IS0 collaborates

22、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, Pari 3. Draft International Standards adopted by the technical committees are circula

23、ted to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IS0 shall not be h

25、link systems 1 Scope This International Standard specifies the minimum level of requirements for construction, operation and installation of geared link steering systems on all types of small craft of hull length up to 24 m. It excludes steering systems covered by IS0 8848 and IS0 9775. 2 Terms and

26、definitions For the purposes of this International Standard, the following terms and definitions apply. 2.1 geared link system system in which rotation of the steering wheel positions the rudder blade by means of gearboxes, which converts the rotary motion to a push/pull force on the rudder operatin

27、g lever, via a draglink assembly 2.2 draglink component linking the rack operating lever to the rudder operating lever, which transmits the push and pull forces and allows rotational and angular misalignment 2.3 rudder operating lever component fixed to the rudder, transmitting the torque to the rud

28、der shaft from the steering system 2.4 rack operating lever component fixed to the shaft of a steering system which rotates in relationship to movement of the steering wheel and achieves a corresponding movement of the rudder operating lever via the draglink 2.5 maximum output force force that the s

29、ystem can supply upon application of a 450 N force tangentially to the wheel 1 3 Illustration of a geared link steering system Figure 1 shows a geared link system and remotely mounted direct link system.

The

31、 manufacturers specification for the maximum permissible output torque shall be used to determine the tangential torque tests as specified in 6.3. 4.1.2 Fasteners All threaded fasteners whose integrity affects safe operation of the steering system shall be provided with a means for locking. 4.1.3 Ma

32、terials The choice and combination of materials shall be such as to minimize the risk of corrosion and galvanic action. 4.2 Specific 4.2.1 Rudder angle The steering system manufacturer shall specify the maximum rudder angle. 4.2.2 Compass interference Materiais used in the various components of the

33、steering system as supplied shall not affect the accuracy and reliability of a compass mounted on the pedestal, if used, whatever the steering angle may be. 4.2.3 Draglink The construction of the draglink shall be such that it will allow k 20 mm of length adjustment and a minimum of 15“ angular misa

34、lignment. Means shall be provided to secure the draglink after adjustments (see Figure 2). Where the rudder lever and the operating lever are in the same plane and there is no angular misalignment, a clevis fitting is permissible. 3 STD.BSI ES EN IS0 13929-ENGL 2001 m 1624669 0697242 089 EN IS0 1392
