鍵和鍵連接分頁導(dǎo)航平鍵
普通平鍵(摘自GB/T 1095-2003往蚕， GB/T 1096-2003)
注：1．在工作圖中铭懂，軸槽深用d-t或t標(biāo)注松摘，轂槽深用d+tl標(biāo)注督垮。(d-t)和(d+t1)尺寸偏差按相應(yīng)的t和t1的偏差選取，但(d-t)偏差取負(fù)號(-)乳栈。
2．當(dāng)鍵長大于500mm時(shí)影啸，其長度應(yīng)按GB／T321-1980優(yōu)先數(shù)和優(yōu)先數(shù)系的R20系列選取。
3．表中每l00mm長的質(zhì)量系指B型鍵组伤。
4. 較高的偏差對于B型鍵應(yīng)為h9羡财。
5．當(dāng)需要時(shí)监镰，鍵允許帶起鍵螺孔，起鍵螺孔的尺寸按鍵寬參考表6.3-6中的d0選取伐怀。螺孔的位置距鍵端為b～2b俐芬，較長的鍵可以采用兩個(gè)對稱的起鍵螺孔。
6. 標(biāo)記示例：圓頭普通平鍵（A型）细溅，b=10mm,h=8mm,l=25mm
鍵 10×25 GB/T 1096-2003
對于同一尺寸的圓頭普通平鍵（B型）或單圓頭普通平鍵（C型）,標(biāo)記為：
鍵 B10×25 GB/T 1096-2003
鍵 C10×25 GB/T 1096-2003
7. 本表的單位是mm褥傍。
