Basic dataStandard ID: GB/T 18325.1-2001 (GB/T18325.1-2001)Description (Translated English): Plain bearings. Bearing fatigue. Plain bearings in test rigs and in application under conditions of hydrodynamic lubrication Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: J12 Classification of International Standard: 21.100.10 Word Count Estimation: 12,182 Date of Issue: 2001-02-26 Date of Implementation: 2001-09-01 Quoted Standard: GB/T 1031-1995; ISO 7902-1; ISO 7902-2; ISO 7902-3; Adopted Standard: ISO 7905-1-1995; IDT Issuing agency(ies): State Quality and Technical Supervision Summary: This standard specifies: by calculating fatigue to improve the comparability of stress test results - Method sliding bearing alloy layer. In applications also require an equally calculation, hydrodynamic oil film because the stress generated stress caused -, so must complete to clarify operation and lubrication conditions, addition to dynamic load, outside dimensions and operating characteristics, also fatigue system to make the following detailed requirements: a) under dynamic loading conditions, varies with time and location bearing minimum film thickness when the run, should ensure not due to the mixed lubrication or overheating in localized shear, b) moving Under load conditions, over time in the circumferential direction and in the axial direction the pressure distribution, c) generated in the bearing alloy layer varies with time and location stress, particular maximum alternating stress. In addition, sliding bearing fatigue strength may be subject to produce mixed lubrication, abrasion, dirt, and other chemical reactions friction in use influence, thus fatigue complicated. Therefore, fatigue strength of this standard will be strictly limited entirely by the hydrodynamic bearing surface of the lubricant film separating conditions. This standard applies to: run at full pressure lubrication hydrodynamic conditions in test bench and applications oil lubricated cylindrical bearings, It includes the bi-metal and metallic multilayer plain bearings Dynamic load.
