コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to general-purpose cylindrical gear grinding machines. It specifies the basic safeguarding technical requirements and measures, along with verification methods, to address the main hazards associated with these machine tools. It is mandatory for manufacturers producing gear grinding equipment for the Chinese market. The standard references GB 15760-2004 for general metal-cutting machine tool safety.

技術要求

The standard outlines comprehensive safety requirements to mitigate mechanical hazards, such as crushing, shearing, and entanglement risks associated with moving parts like grinding wheels and worktables. Manufacturers must ensure that moving parts do not create pinch points or shear hazards. It also addresses the prevention of component ejection and requires reliable clamping devices for grinding wheels and workpieces. Regarding electrical and control systems, the standard mandates compliance with GB 5226.1 for electrical equipment. It specifies requirements for control devices, start/stop mechanisms, and emergency stop functions to prevent unexpected start-up or hazardous movements during system failures. Control systems must be designed to fail-safe conditions. The document also covers noise limits, hazardous substance emissions (such as dust and oil mist), and fire/explosion prevention. It includes specific ergonomic requirements for operator interfaces, such as maximum operating forces for handwheels and appropriate installation heights for control panels, referencing GB/T 14775 and GB/T 16251. Furthermore, the standard details requirements for safeguarding devices, including fixed, movable, and adjustable guards, as well as interlocking mechanisms. Proper safety signs and user information must be provided to warn operators of residual risks.

試験方法

Verification methods primarily involve visual inspection, functional checks, and measurement of specific parameters. Key tests include measuring noise sound pressure levels under no-load conditions (referencing GB/T 16769), testing oil mist concentration (referencing GB/T 23574), and verifying dust concentration (referencing GB/T 23573). Functional tests are also required for control systems, interlocking devices, and emergency stop functions.
