NOTEThe lubrication fittings are hereinaft
13、er referred to as fittings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO6392. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agr
14、eements based on this part of ISO6392 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 2081:1986, Metallic coatings Electroplated coatings of
15、zinc on iron or steel. ISO 6165: 1) , Earth-moving machinery Basic types Vocabulary. 3 Description Fittings for earth-moving machinery shall be of the types shown inFigure 1. 4 Material, design and manufacture 4.1 Material Unless otherwise specified, fittings shall be made from manufacturers standar
16、d steel. 4.2 Hardness Fittings used where there is a high frequency of greasing and/or direct contact with soil or sand shall have their heads surface hardened. In cases where surface-hardening is required, the minimum hardness shall be83HRA or55HR30N and shall have a minimum case depth of0,10mm. Wh
17、ere surface-hardened heads are not required, hardness is not specified in general. 4.3 Finish Bodies of fittings shall be electroplated with zinc and chromate treatment in accordance with ISO2081. The thickness of the coating shall be atleast5m. 4.4 Workmanship Fittings shall be free from burrs, loo
18、se scale, sharp edges, and any other defects that might affect their intended function. 4.5 Check valve Fittings shall be supplied with check valves which will provide a seal against the ingress of foreign material, but will admit lubricant under pressure and prevent its escape. 5 Shape, dimensions
19、and tolerances The shape, dimensions and tolerances of fittings shall conform to the requirements given inFigure 1 andFigure 2 andTable 1. The tabulated dimensions shall apply to the finished processed parts. 6 Proof pressure of fittings Fittings shall accept grease injection at an injection pressur
20、e of up to20MPa. 7 Required ambient space at the mounting position of fittings The required ambient space is such that a grease-gun nozzle, with18mm outer diameter, and its extension can be inclined to a minimum angle of25 in one direction (seeFigure 3). 1) To be published.
