Foreword
GB/T 12613 "Plain bearings - hub" consists of the following seven parts.
--- Part 1. Dimensions;
--- Part 2. outside and inside diameter of the test data;
--- Part 3. Lubrication holes, grooves and pockets;
--- Part 4. Materials;
--- Part 5. diameter test;
--- Part 6. inner diameter of the test;
--- Part 7. Measurement of wall thickness of thin-walled sleeve.
This part of GB/T 12613 Part 2.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 12613.2-2002 "Plain bearings - Wrapped bushes - Part 2. outside and inside diameter of the test data." versus
GB/T 12613.2-2002 compared to major changes are as follows.
--- Chapter 2 normative references deleted GB/T 18331.1-2001, ISO 12307-2;
--- Increased flange diameter symbol Dfl, housing bore diameter symbol DH, bend radius flange symbol r, symbol flange thickness, diameter
Do symbol limit deviations from the "T" to "ΔDo";
--- Increased flanged bushings inside and outside diameter Figure;
--- 1 comments added provisions "nominal wall thickness of the steel backing layer thickness of 0.5mm removing the smallest chamfer part is 0.2mm." And
"Rmax = s3";
--- Increased Table 3 "sleeve wall thickness s3, steel back thickness s1, s2 bearing material layer of nominal size";
--- Refine and increase the effective cross-sectional area of \u200b\u200bthe formulas applicable type of material;
--- Fixed sample calculation test mode diameter dch, calculation data 1 (2002 edition as 30.072 mm, this edition is
34.072mm);
--- Test Method B increased provisions applicable to the sleeve outer diameter of 120mm or less;
--- Test Method C increase in provisions applicable to the inner diameter of 120mm below the hub;
--- Test Method C through increased regulation and the only regulation size calculation formula;
--- Increase the inner diameter of the ring is calculated (Excerpts tables 6) Test Method C time;
--- Modifies the data sample of test method C;
--- Revised test method D data showing the example of FIG.
This section uses the translation method identical with the international standard ISO 3547-2.2006 "Plain bearings - Wrapped bushes - Part 2. outside and
The inner diameter of the test data. "

Plain bearings - Wrapped bushes
Part 2. outside and inside diameter of the test data
1 Scope
GB/T 12613 provisions of this part of the single-layer and multi-layer material rolled into a bush outside and inside diameters of the test data, and provides
Test methods, labeling methods.
Since the sleeve wall thickness measurement is carried out in a free state, the figure does not specify test requirements (according to GB/T 12613.5 and
GB/T 12613.6).
Note 1. Due to the manufacturing method of rolling bush, on the outer surface of the sleeve will be a slight depression; similarly, there Lubrication holes, grooves and indentations appear hub
Deformation. Therefore, measuring the wall thickness of the sleeve should avoid these locations.
Note 2. In addition to the marked and designated special units, GB/T 12613 in this section All dimensions are in millimeters.
