Foreword
GB/T 34633 "plain bearing shell bearing" is divided into three parts.
--- Part 1. Block type plain bearings;
--- Part 2. Offset flanged plain bearings;
--- Part 3. Central flange bearing.
This section GB/T 34633 Part 3.
This section uses redrafted law to amend the use of international standards ISO 11687-3.1995 "sliding bearing shell bearing plain bearings
Part 3. Central Flanged Bearings ".
This part of ISO 11687-3.1995 technical differences.
--- On the normative references, this section made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation
Concentration reflected in Chapter 2 "Normative references", the specific adjustments are as follows.
● Equivalent to the international standard GB/T 131 instead of ISO 1302;
● Equivalent to the international standard GB/T 1184 instead of ISO 2768-2;
● Equivalent to the international standard GB/T 1804 instead of ISO 2768-1;
● Equivalent to the international standard GB/T 6414 instead of ISO 8062;
● Equivalent to the use of international standards GB/T 9439 instead of ISO 185;
● GB/T 11352 modified to adopt international standards instead of ISO 3755;
--- Chapter 3 increased the form of bearing insulation code to improve the description of the bearing type;
--- Chapter 6 "Materials", as a result of ISO 630.1980, ISO 683-11.1987, ISO 426-1.1983, ISO 426-2.1983
Obsolete, and there is no corresponding material grades in our country, so the domestic industry is using our standard GB/T 699,
GB/T 1174, GB/T 1348, GB/T 8740 and GB/T 17107 in the material grades instead of the corresponding material in the international standard
Material grades, in order to adapt to the actual production and use of the country; in this standard reference to the contents of national standards and international standards Corresponding content
The same conditions, the use of non-equivalent national standards GB/T 9439 and GB/T 11352, respectively, instead of international standards
ISO 185 and ISO 3755, to meet the needs of the exchange of standardization work.
--- According to China's actual production and use, an increase of 35,45 models of the central flange-type plain bearings and shaft design
Features to expand the standard applicability.
This part is proposed by China Machinery Industry Federation.
This part of the National Standardization Technical Committee of the sliding bearing (SAC/TC236) centralized.
