GOST 34385-2018 PDF

Full title and description

GOST 34385-2018 — "Буксы и адаптеры для колесных пар тележек грузовых вагонов. Общие технические условия" (English: "Axle-boxes and adapters for wheelsets of freight wagon bogies. General specifications"). The standard sets technical requirements, acceptance rules and test methods for axle-boxes (буксы), adapters and composite adapters used in freight-wagon bogies.

Abstract

This interstate standard establishes general specifications for axle-box housings and adapter components that sit between the outer rings of wheelset bearings and the support or thrust surfaces of wheelset openings in side frames of freight wagon bogies (primarily two-axle, three-piece bogies per GOST 9246). It defines material and mechanical requirements, dimensional and fitting rules, surface treatment and hardness, inspection and acceptance procedures, and test methods required for production and quality control. The standard may also be applied to components of three- and four-axle bogies where appropriate.

Scope

The standard applies to axle-boxes and their constituent parts, adapters and composite adapters, and any other components of two-axle three-piece freight-wagon bogies (per GOST 9246) located between the outer rings of wheelset bearings and the support and/or thrust surfaces of the wheelset openings in side frames. It establishes general technical requirements, acceptance rules and control (inspection and test) methods. Application to axle-box parts and adapters of three- and four-axle bogies is permitted where appropriate.

Key topics and requirements

• Scope and definitions for axle-box housings, adapters and composite adapter parts used in freight-wagon bogies.
• Material and metallurgy requirements (per applicable GOST material standards for steels and castings), including referenced steel grades and casting specifications.
• Dimensional tolerances, fits and seatings for bearing bores, adapter interfaces and mating surfaces in accordance with rolling-stock fitting rules.
• Hardness and surface-treatment requirements for bearing support surfaces and thrust surfaces (including specified hardness values and measurement methods).
• Non-destructive and destructive test methods, mechanical testing (tensile, impact where required) and sampling regimes for acceptance.
• Inspection, marking, packing and documentation required for delivery and storage of axle-boxes and adapters.
• Normative references and cross-references to related rolling-stock standards (e.g., GOST 9246, bearing and wheelset specifications).

Typical use and users

Manufacturers of axle-box housings, adapters and related bogie components; rolling-stock equipment designers and engineers; railway vehicle repair and maintenance depots; quality and testing laboratories; procurement and certification bodies in railway industry supply chains. The standard is used as a technical specification for production, acceptance, inspection and maintenance operations.
