Full title and description
GOST 13755-2015 — "Основные нормы взаимозаменяемости. Передачи зубчатые цилиндрические эвольвентные. Исходные контуры" (English: Basic norm of interchangeability — Cylindrical involute gears for general and heavy engineering. Standard basic rack tooth profile). The standard establishes the nominal (standard) basic contour of teeth for cylindrical involute gears (external or internal) with module 1 mm and above.
Abstract
This standard defines the geometric parameters and reference (basic) rack tooth profiles used as the source contour for design and interchangeability of cylindrical involute gears used in general and heavy engineering (module ≥ 1 mm). It updates and replaces the previous edition (GOST 13755‑81) and aligns national requirements with corresponding international references.

Scope
The standard applies to cylindrical involute gear pairs (external and internal) intended for general and heavy engineering with module of 1 mm and above. It specifies the parameters of the standard basic rack (source contour) tooth profile used as the reference geometry for design, manufacturing drawings and interchangeability assessments; it also references related national norms (for example GOST 9563 for module definitions) and aligns with relevant ISO/IEC terminology where applicable.
Key topics and requirements
- Definition of the standard basic rack tooth profile (nominal/source contour) for cylindrical involute gears.
- Geometric parameters and dimensions for the basic contour applicable to modules ≥ 1 mm.
- Rules for applying the basic contour to external and internal gear teeth and for constructing coincident/standard matching contours.
- References and harmonization with related national and international standards (replaced earlier GOST 13755‑81 and notes correspondence with ISO documents).
- Normative definitions, terms and figures illustrating the standard contour and its use in drawings and calculations.
Typical use and users
Primary users include gear designers, mechanical engineers, manufacturing engineers, quality and metrology laboratories, tooling and hob manufacturers, standards specialists, and technical libraries in heavy and general engineering sectors. The standard is used when specifying gear tooth geometry on drawings, for compatibility/interchangeability assessments, and to ensure consistent reference geometry for calculation and inspection.
Related standards
Key related and referenced standards include the superseded GOST 13755‑81 (previous edition), GOST 9563 (modules of gears), and related GOSTs covering gear accuracy, strength calculation and terminology (examples: GOST 1643‑81, GOST 21354‑87 and national references to the ISO gear committee documents cited in the text).
