關於平鍵

平鍵(Key)嵌在軸與輪轂的鍵槽之間傳遞扭力,是最常見、成本最低的軸轂連接方式。分平行鍵(方鍵/角鍵)、圓頭鍵、半圓鍵(伍德鍵);材質與熱處理決定它能傳多大扭力。

平鍵常見問題

平鍵、平行鍵、方鍵、鍵條有什麼不同?

平行鍵(Parallel Key)是正式名稱,台灣多叫平鍵;寬與高相等的俗稱方鍵。鍵條是還沒裁切的長條料(常見 300mm 或 350mm 一支),買回去依輪轂寬度自行裁切。

平鍵的規格怎麼看?

寫成「寬 × 高 × 長」,例如 6*6*20。寬與高依軸徑決定:依 DIN 6885,軸徑超過 17 到 22mm 用 6×6,超過 22 到 30mm 用 8×7,超過 30 到 38mm 用 10×8。

單圓鍵、雙圓鍵、平頭鍵怎麼分?

看兩端的形狀:兩端都是圓弧的是雙圓鍵(DIN 6885 A 型),兩端都是平的是平頭鍵(B 型),一端圓一端平的是單圓鍵(C 型)。
