配合公差 規格表
3種規格資料
配合是規定軸與孔之間尺寸關係的公差設計概念。間隙配合用於旋轉/滑動部位；過盈配合用於永久固定；過渡配合用於定位。正確指定ISO 286配合組合才能保證裝配品質。
常見問題 (FAQ)
What is the difference between H7/g6, H7/k6, and H7/p6?
H7/g6 is clearance fit (rotation/sliding), H7/k6 is transition (positioning), H7/p6 is interference (press fit). Higher deviation letters indicate tighter interference.
How do I choose a fit tolerance?
Choose clearance (g–h) where disassembly is needed, transition (j–k) for precise positioning, and interference (m–u) for permanent fixing. Also consider thermal expansion, material, and load.
