A protective ring component used in isolation barriers to prevent contact with hazardous machine parts.

技术定义与适配语境
典型 防护环 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A guard ring is a circular protective component integrated into isolation barriers on industrial machinery. It functions as a physical barrier that prevents accidental contact with moving parts, electrical components, or hazardous areas while allowing necessary operational access. Typically mounted around rotating shafts, gears, or other dangerous elements, it creates a safe perimeter that maintains isolation integrity.

定义
A guard ring is a circular protective component integrated into isolation barriers on industrial machinery. It functions as a physical barrier that prevents accidental contact with moving parts, electrical components, or hazardous areas while allowing necessary operational access. Typically mounted around rotating shafts, gears, or other dangerous elements, it creates a safe perimeter that maintains isolation integrity.
工作原理
The guard ring operates on the principle of physical obstruction and containment. It creates a fixed protective boundary around hazardous machine elements, preventing personnel from reaching into danger zones while allowing the machine to function normally. The ring's design ensures it maintains a consistent safety gap from moving parts, and it often incorporates features like smooth edges and secure mounting to prevent entanglement or dislodgement.
材料
Typically made from durable materials such as carbon steel (ASTM A36)stainless steel (304 or 316 grade)aluminum alloys (6061-T6)or engineering plastics (polycarbonatenylon) depending on application requirements. Materials must have appropriate strengthcorrosion resistanceand temperature tolerance.
Thickness
3-10 mm
Safety Gap
Minimum 6 mm from moving parts
Mounting Type
Bolted, welded, or clamped
Diameter Range
50-500 mm
Surface Finish
Smooth, deburred edges
Temperature Range
-20°C to +150°C
标准
ISO 14120DIN EN 953OSHA 1910.212
