Full title and description

GOST 34510-2018 — Колеса зубчатые тяговых передач тягового подвижного состава. Методы определения изгибной и контактной усталостной прочности. Standard defining laboratory and bench methods to determine bending and contact fatigue strength of gear wheels used in traction transmissions of railway rolling stock (locomotives and powered units).

Abstract

This standard specifies test procedures, specimen preparation and conditioning, required test equipment and loading schemes to evaluate bending fatigue (endurance of individual teeth under repeated bending) and contact fatigue (pitting/contact failure of gear flank surfaces) for cylindrical (involute) gears used in traction transmissions. It includes base test cycle counts, environmental and conditioning requirements, measurement and reporting formats.

Scope

Applies to gear wheels of traction transmissions used in rolling stock and establishes laboratory/bench test methods to determine: (1) bending fatigue strength of gear teeth under cyclic loading, and (2) contact fatigue (surface pitting/wear) strength under repeated contact stresses. The standard sets sample conditioning, ambient test conditions, required loading equipment and schemes (including rolling without slip, rolling with slip and rolling with tangential external load), minimum numbers of tested tooth pairs and base cycle counts for endurance evaluation.

Key topics and requirements

• Definitions and types of gear wheels covered: involute cylindrical gears (straight, helical and herringbone) used in traction transmissions.
• Specimen preparation and conditioning (conditioning time at test temperature, sample selection and witness specimens).
• Test equipment and accuracy requirements (e.g., universal testing machines/stands with specified dynamic load capacity and measurement tolerances; typical equipment referenced: machines with up to 600 kN dynamic load capability and automatic shutdown controls for defects and lubricant failure).
• Loading schemes: rolling without slip, rolling with slip, rolling with external tangential load; procedures for applying load to tooth pair(s).
• Base cycle counts and end-point criteria: typical bending test base 4·10^6 cycles; typical contact fatigue base 10^8 cycles; procedures for increasing load until failure or until base cycles are reached.
• Measurement, evaluation and reporting: recording load amplitude, number of cycles to failure, location and type of failure; processing test results and filling the test protocol form included in the annexes.
• Normative references and cross-references to gear design and strength calculation standards used for interpretation of results (examples cited in the text).

Typical use and users

Used by railway equipment designers, manufacturers of traction gearboxes and gear wheels, materials and heat-treatment engineers, independent and factory test laboratories, certification bodies and maintenance departments to qualify gear designs, validate heat-treatment and surface treatments, and to support acceptance testing and failure investigations of traction gears.

Related standards

Standard references and related documents include national and industry gear and testing standards such as ГОСТ 21354-87 (strength calculation of involute cylindrical gears) and standards addressing precision, materials and testing practices (for example, ГОСТ 30803-2014 and other railway material/component standards). The standard is intended to be used together with general gear design and fatigue assessment documents.
