Aeronavtika - Varnostni obroči za osno pritrditev v okrogle odprtine, jekleni, fosfatirani
Ta standard določa lastnosti jeklenih fosfatiranih varnostnih obročev za osno pritrditev v okrogle odprtine za uporabo v aeronavtiki. Fosfatiranje omejuje uporabo na temperature, ki ne presegajo 200 °C.
General Information
Overview
EN 3382:2012 is a CEN aerospace series standard that defines the characteristics of internal, axial-mounting retaining rings made of steel, phosphated for aerospace applications. The document specifies geometric configuration, dimensional tables (diameter codes), material hardness, surface treatment and storage protection. Because of the phosphating, the rings are restricted to service temperatures not exceeding 200 °C.
Key topics and requirements
- Product type: Axial mounting internal retaining rings (retaining rings for bores).
- Materials: Spring steel with specified hardness:
- Diameter codes 008–038: 480–530 HV
- Diameter codes 040–165: 440–510 HV
- Surface treatment: Phosphate coating to EN 2793 (class A). Rings must be protected with grease or oil prior to storage.
- Dimensions and mass: Detailed tables and figure in EN 3382 give nominal bore (diameter code), ring dimensions (A, B, D1…D4, P, S, R), tolerances and approximate mass per 1 000 pieces.
- Designation and marking: Example designation format - RETAINING RING, INTERNAL, AXIAL MOUNTING EN 3382 – 016. Marking to be applied per EN 2424 (style G).
- Associated technical rules: Technical specification and mounting guidance are referenced - see EN 3380 for technical specification and EN 3425 for groove dimensions for axial internal rings.
- Limitations: Phosphated surface imposes a maximum recommended temperature of 200 °C; details and requirements for mounting and groove dimensions are covered by referenced standards.
Applications
- Used wherever positive axial retention of components on a shaft or within a bore is required in aerospace assemblies - for example, securing bearings, spacers, washers and other locking elements in aircraft and space systems.
- Typical users include design engineers specifying retention hardware, manufacturing and components suppliers producing spring-steel retaining rings, procurement teams sourcing aerospace parts, and quality/maintenance teams verifying compliance.
Who would use EN 3382:2012
- Aerospace component manufacturers and fastener suppliers
- Mechanical and aerospace design engineers
- Quality assurance and procurement in aviation and space industries
- Maintenance, repair and overhaul (MRO) organizations verifying part conformity
