定义
A precision-engineered metal housing component designed to encase and protect the sealing elements of a propeller shaft seal assembly. It serves as the primary structural interface between the seal and the surrounding mechanical system, ensuring proper alignment, retention, and protection against external contaminants while withstanding operational stresses including vibration, thermal cycling, and mechanical loads.
工作原理
The metal case functions by providing a rigid, dimensionally stable enclosure that securely positions the sealing lip or element against the rotating shaft. It transfers mounting forces evenly, maintains seal geometry under pressure, and acts as a barrier against dirt, moisture, and debris. Its design ensures consistent contact pressure and alignment to prevent leakage and premature wear.
材料
Typically manufactured from cold-rolled steel (CRS)stainless steel (grades 304 or 316 for corrosion resistance)or aluminum alloys (e.g.6061-T6 for lightweight applications). Surface treatments may include zinc platingphosphate coatingor powder coating for enhanced durability and corrosion protection.
Hardness
70-90 HRB for steel
Outer Diameter
50-200 mm (varies by application)
Wall Thickness
1.5-3.0 mm
Pressure Rating
Up to 10 bar static
Temperature Range
-40°C to +150°C
标准
ISO 6194DIN 3760
