键槽 规格表
2种规格数据
键槽是在轴和轮毂上加工的用于安装键传递扭矩的槽。KS B 1311规定了各键公称尺寸的轴和轮毂槽深。配合组合——键-轴N9/P9、键-轮毂Js9/D10——根据载荷特性选择。
常见问题 (FAQ)
What are the machining methods for keyways?
Shaft keyways are machined by milling or slotting (shaping); hub keyways are typically broached. End-mill machining creates a rounded keyway end; slotting creates a square end.
What is the difference between keyway fit tolerances N9, Js9, and P9?
N9 (normal) for general power transmission; Js9 (sliding) for easy key insertion and removal; P9 (interference) for heavy shock loads. Both shaft and hub keyway tolerances must be considered together.
