Preface

Goals, basic principles and main procedure of works on interstate standardization have been established in GOST 1.0−92 «interstate standardization system. Basic provisions» and GOST 1.2−97 «interstate standardization system. Interstate standards, rules and recommendations on interstate standardization. The procedure of development, adoption, application, renewal and cancellation"

Data on standard

1 PREPARED by the Russian research Institute of standardization and certification in engineering (VNIINMASH) of the Federal Agency for technical regulation and Metrology on the basis of their own authentic translation of the standard referred to in paragraph 4

2 recorded by the Interstate technical Committee for standardization MTK 344 «plain Bearings"

3 ACCEPTED by the Interstate Council for standardization, Metrology and certification (Protocol No. 29 of June 24, 2006)

The adoption voted:

4 this standard is identical with ISO 4383:2000 «plain Bearings. Multilayer materials for thin-walled plain bearings» (ISO 4383:2000 «Plain bearings. Multilayer materials for thin-walled plain bearings», IDT)

5 by Order of the Federal Agency for technical regulation and Metrology dated December 25, 2008 N 685-St interstate standard GOST ISO 4383:2006 promulgated as the national standard of the Russian Federation from July 1, 2009

1 Scope

This standard specifies the basic requirements for multilayer materials used for the manufacture of thin-walled plain bearings (liners, bushings, thrust washers). The layered material consists of steel backing and a layer of bearing material (cast, sintered, rolled). Possible running-the layer obtained by electrolytic deposition.

Note — the environmental Impact will limit the use of certain materials such as lead.

3 Technical requirements

3.1 Chemical composition of the bearing layer

The chemical composition of materials must meet the requirements listed in tables 1 to 5, where single numbers represent maximum values.


Table 1 — Alloys of lead and tin (see ISO 4381)

Table 2 — Alloys based on copper

Table 3 — Alloys based on aluminium

Table 4 — Run the surface of the sintered bronze with polymer

Table 5 — Bedded layers

3.2 Steel Foundation

Chemical composition of steel for the base is determined by agreement between the manufacturer and the consumer. Mainly used mild steel.

For composite materials, bronze / polymer indicated in table 4, as the basis can be used steel with a copper coating.

3.3 Bearing layer

Bearing layer based on tin and lead must meet the requirements specified in table 1.

The bearing layer of copper-base shall conform to the requirements specified in table 2.

Bearing layer on the basis of aluminum shall conform to the requirements specified in table 3.

Bearing layer on the basis of sintered bronze and polymers must meet the requirements specified in table 4.

Note — Developed new materials based on aluminum, containing aluminum and silicon or manganese, as well as soft materials such as lead or tin.

3.4 Running-the layer corresponding to the requirements specified in table 5, can be used for bearing layers, as shown in table A. 2.

The thickness of the running-layer and any intermediate layers between the bearing layer and running-in layer is determined by agreement between the manufacturer and the consumer.

3.5 Properties and selection of materials

Recommendations on the hardness of the bearing material in the form of a strip and the use of bearing materials is given in Appendix A.

4 Marking
