GOST 6528-53 PDF

Full title and description

GOST 6528-53 — "Калибры для шлицевых валов и отверстий с эвольвентным профилем. Допуски" (English: "Gauges for splined shafts and holes with involute/evolute profile. Tolerances"). The standard specifies types and dimensional tolerances for gauges used to control splined shafts and matching holes (including measuring rollers for tooth thickness and groove width) for nominal outer diameters up to 150 mm and modules up to 5 mm.

Abstract

GOST 6528-53 establishes requirements for plug (go) and ring (no-go) gauges and measuring rollers intended for inspection of involute splined connections. It gives acceptable tolerances, classification of gauge types, and normative references necessary to ensure interchangeability and correct fit of splined shafts and mating holes in mechanical assemblies. The standard was introduced in the USSR in 1953 and remains a normative reference for spline gauge design and inspection in the post‑Soviet standards ecosystem.

General information

• Status: Active / действующий (standard retained and in force in national/regional catalogs).
• Publication date: Introduced 1953 (approved 11 March 1953; date of effect commonly cited as 01.07.1953 or 01.01.1954 in some registries).
• Publisher: Approved by the Administration for Standardization at the Council of Ministers of the USSR (Gosstandart-related authority); later reprints published by standard publishing houses.
• ICS / categories: ICS 17.040.30 (Linear and angular measurement; measuring instruments) — metrology and measuring instruments category; KGS group G28 (measuring gauges / industrial tool classification).
• Edition / version: Original 1953 edition; contains at least one recorded amendment (correction published in 1958). Reprints and later compilations exist.
• Number of pages: Commonly published in short form (about 11 pages in several electronic reprints); some library/catalog entries list 15 pages depending on publisher/reissue.

Scope

The standard applies to gauges for inspection of splined shafts and holes with involute (evolute) profiles where the nominal outside diameter does not exceed 150 mm and the module does not exceed 5 mm. It also covers measuring rollers used to control tooth thickness of shafts and groove width of holes, and references related profile and fit standards (notably GOST 6033-51 for spline connections). The standard is intended for use in manufacturing quality control and metrology laboratories to ensure interchangeability of splined connections.

Key topics and requirements

• Types of gauges specified: complex plug gauges (go/no-go), complex ring gauges, individual measuring rollers for tooth thickness and groove width.
• Dimensional tolerances and limit deviations for gauge elements appropriate to spline sizes up to 150 mm and module up to 5 mm.
• Normative references and cross‑references to spline geometry and fit standards (e.g., GOST 6033-51) and to tolerance/fit systems (relevant OST and GOST documents).
• Requirements for measuring rollers used to assess tooth thickness and groove width across all sizes specified in the referenced spline standard.
• Marking, inspection and acceptance criteria for gauges used in production and inspection. (General marking and metrological requirements typical of GOST gauge standards are applied.)

Typical use and users

Primary users are manufacturers of splined shafts and mating components (gearboxes, drives, couplings), inspection and calibration laboratories, toolmakers producing gauges, and design/quality engineers responsible for ensuring correct fits and interchangeability in mechanical assemblies. The standard supports production control, incoming inspection, and periodic gauge verification in industrial and repair settings.

Related standards

Key related normative documents include GOST 6033-51 (involute spline connections — dimensions and sizes), OST 1012 and OST NKM 1011 (tolerance/fit references cited by the standard), and general inter‑changeability norms such as GOST 6636‑69. The standard is part of the broader family of GOSTs covering gauges, thread and gear measurement, and metrological practices.

FAQ

Q: What is this standard?

A: GOST 6528-53 is a Soviet (interstate) standard that specifies gauge types and tolerances for inspection of involute splined shafts and matching holes (including measuring rollers). It was approved in 1953 and remains listed in national standards catalogs.

Q: What does it cover?

A: It covers dimensions, tolerance limits, and types of gauges (complex plug and ring gauges, measuring rollers) for splines with nominal outer diameters up to 150 mm and module up to 5 mm, plus applicable normative references for spline geometry and fits.

Q: Who typically uses it?

A: Toolmakers, manufacturers of splined components, metrology and quality control laboratories, and engineers responsible for inspection and verification of spline fits.

Q: Is it current or superseded?

A: Registry entries in multiple Russian and regional standards catalogs list GOST 6528-53 as действующий (active). Although originally published in 1953, it has been retained/reprinted in collections and may be used alongside newer national/regional standards where applicable. Users should check the latest national/regional standards catalogs for any modern replacements or updates before applying the standard.

Q: Is it part of a series?

A: It is part of the family of GOST standards addressing gauges, metrology and spline/gear connections (referencing GOST 6033-51 and other tolerance/fit documents). It is not a multi‑part numbered series by itself but sits within the broader GOST framework for measurement instruments and mechanical fits.

Q: What are the key keywords?

A: Spline gauges, splined shafts, involute profile, plug/ring gauges, measuring rollers, tolerances, metrology, GOST 6528-53.
