Описание (английский):

Specifies the dimensional requirements and the surface roughnesses. The corresponding requirements of heavy freight vehicle axles or of axles for speeds under 100 kg/h shall be subject to agreement between the purchaser and manufacturer at the time of enquiry and order. In addition to this requirements, the general technical delivery requirements of ISO 404 apply.

Overview

ISO 1005-9:1986 - "Railway rolling stock material - Part 9: Axles for tractive and trailing stock - Dimensional requirements" defines the dimensional and surface-finish requirements for axles used in locomotive (tractive) and trailer (trailing) rolling stock. It complements the quality requirements in ISO 1005/3 and the general delivery rules of ISO 404. The standard ensures axles are produced with the tolerances, machining allowances and surface roughness needed for safe wheelset assembly and reliable in-service performance.

Key topics and technical requirements

Scope and purchaser data: Purchasers must specify the part number, drawing, intended speed range (Normal or High), degree of finish (unmachined, rough‑machined, half‑finished, finished, ready for assembly), machining allowances, deviations from the standard values, and any special geometric tolerances or inspection options.

Degrees of finish: Definitions for unmachined, rough machined, half finished, finished and ready for assembly conditions (see ISO 1005/3).

Dimensional requirements: Machining allowances and dimensional tolerances are given for wheel seats, journals, abutments and axle body; values differ by finish and speed class and some checks are mandatory while others are optional by agreement.

Geometrical tolerances: Form and positional requirements such as cylindricity, run‑out, straightness and journal/seat concentricity are specified to support correct wheel and bearing assembly. Typical cylindricity values are in the order of 0.015 mm (see tables in the standard).

Surface roughness: Arithmetic mean deviation R_a is specified for critical surfaces. For example, wheel and gear seats typically require a fine finish (about 0.8–1.6 μm R_a), while journals often require ≤ 0.8 μm R_a; axle body surfaces have larger allowable roughness (values up to several μm).

Inspection and verification: The standard specifies which checks are mandatory and which are subject to purchaser agreement. Verification plans (sample sizes, tests) must be agreed at enquiry/order time to ensure wheelset assembly without further machining.

Applications and users

Axle and wheelset manufacturers for production tolerancing and process control.

Rail vehicle designers and OEMs to specify acceptances and interfaces.

Procurement teams and purchasers to define order requirements (finish, tolerances, inspection).

Quality and inspection engineers for acceptance testing and supplier audits.

Maintenance and refurbishment workshops when reconditioning axles or preparing for wheel mounting.
