Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 23339-2009 "Crankshaft technical conditions." This standard compared with GB/T 23339-2009,
In addition to editorial changes outside the main technical changes are as follows.
--- Modify the normative references (see Chapter 2,.2009 edition Chapter 2);
--- Modify the chemical composition of forged steel crankshaft requirements (see 3.2.1.2,.2009 edition 3.2.1.2.1);
--- Added "Class A non-quenched and tempered steel inclusions level determined by the supply and demand sides negotiated" (see 3.2.1.3);
--- Increasing the chemical composition of ductile iron crankshaft material, mechanical properties requirements (see 3.2.2.2, 3.2.2.3);
--- Modify the straightness technical requirements for the implementation of the provisions of the drawings (see 3.3.7, 3.4.6,.2009 version 3.3.6, 3.4.4);
--- Modify the grain size of crankshaft forgings (see 3.8.3.3.3.3.3.3,.2009 edition of 3.3.7.1, 3.3.7.3);
--- Modify the microstructure requirements (see 3.4.1.7,.2009 edition 3.4.5.1);
--- Modify the surface of the crankshaft to strengthen the choice of way (see 3.5.1.1,.2009 edition 3.5.1);
--- Modify forged steel crankshaft journal surface hardened layer depth and hardness requirements (see 3.5.1.2.1,.2009 edition 3.5.2.1);
--- Modify the requirements of journal quenching (see 3.5.1.2.3,.2009 edition 3.5.2.3);
--- Increased fillet rolling requirements (see 3.5.1.5);
--- Revised surface roughness requirements (see 3.5.2,.2009 version 3.6 of Table 2, 4.8.8);
--- Removed "6-cylinder engine and crankshaft above, allowing the use of intermediate support" (see.2009 version 3.7.5);
--- Increased torsional fatigue strength requirements and test methods (see 3.5.8,4.15);
--- Revised endurance test requirements (see 3.5.9,.2009 version 3.12);
--- Modify the sampling site requirements (see 4.4.1,.2009 edition 4.4.1);
--- Modify the hardened layer test method (see 4.2.2.2,.2009 edition 4.5.2.2);
--- Deleted "The total box must not exceed the total mass of 50kg (single package, not subject to this limit)" (see.2009 version 6.2).
