| Summary | This standard specifies test roll sleeve OD (GB/T 12613. 2 of the test method A, B, D) requirements, but provides the necessary testing methods and testing equipment. Because stem diameter in the free state is elastic, but after the installation because stem diameter and housing bore size difference, bushings will greatly suit bore size. Thus, stem diameter detection equipment should be dedicated for applying a constant load. |

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 5.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 18331.1-2001 "Plain bearings - Wrapped bushes outside diameter detection." And GB/T 18331.1-2001
Compared main changes are as follows.
--- Remove obsolete and incorrect references;
--- Symbol test mode and positioning plug symbol by the subscript "c" to "ch";
--- Increasing the outer diameter of the ring symbol "do", added between mold inspection length, width, and two mold halves from the symbol "x", "y", "z", increase foreign
Diameter tolerance symbol "Do", increase the dial gauge reading "Δz", increase the girth indicator reading "ΔzD";
--- Remove the outer diameter of the elastic damping symbol "Ered", confidence symbol "Pzw", diameter tolerance symbol "T", the symbol of Measurement Uncertainty
Uncertainty symbol "u", the measuring device "uE", the first and second measurement readings symbol value difference "Δx", "Δx" flat
Mean symbol "Δx", the standard deviation of the symbol "σ", the standard deviation of the symbol Δx "σΔx";
--- Test Method A test module added to the technical requirements and positioning plug (edition 8.2), an increase of test mold base hole length and width
Degree requirements, the housing bore surface roughness test mode by the Ra1.6 to Ra0.2;
--- Test Method B ring size requirements change, the surface roughness Ra1 to Ra0.2;
--- Increased test method D (for GB/T 12613.2-2011 The test method D detailed provisions).
This section uses the translation method identical with the international standard ISO 3547-5.2007 "Plain bearings - Wrapped bushes - Part 5. OD inspection
Experience. "
And ISO 3547-5.2007 as compared to this section made the following editorial changes.
--- To increase the range. "Note 2. Except otherwise specified and the specified unit, GB/T 12613 in this section All dimensions in mm
Meter. "Delete the text on the table," millimeters ";
--- Equivalents adoption of international standards in place of the standard corresponding to international standards.
This part is proposed by China Machinery Industry Federation.
Bearing this in part by the National Standardization Technical Committee (SAC/TC236) centralized.

Plain bearings - Wrapped bushes
Part 5. OD inspection
1 Scope
GB/T 12613 in this section according to GB/T 27939-2011, the provisions of the outer diameter of the sleeve rolling test (GB/T 12613.2 in the specimen
Test method A, B, D) requirements, and provides the necessary testing methods and testing equipment.
Since the outer diameter of the sleeve in the free state is resilient, but after the installation due to differences in the outer diameter of the sleeve and the housing bore size, the pole sleeve
Earth adaptation seat hole size. Therefore, the detection of the outer diameter of the sleeve should apply a constant load on the special equipment to carry out.
Note 1. Wrapped bushes - Dimensions and tolerances in GB/T 12613.1 given wall thickness inspection GB/T 12613.7 specified in.
Note 2. In addition to the marked and designated special units, GB/T 12613 in this section All dimensions are in millimeters.
