平鍵(jian)(jian)(jian)(jian)，是依靠(kao)兩個(ge)側面(mian)作(zuo)為工作(zuo)面(mian)，靠(kao)鍵(jian)(jian)(jian)(jian)與鍵(jian)(jian)(jian)(jian)槽(cao)側面(mian)的擠壓(ya)來(lai)傳遞轉(zhuan)矩(ju)的鍵(jian)(jian)(jian)(jian)。平鍵(jian)(jian)(jian)(jian)分為普(pu)通(tong)型平鍵(jian)(jian)(jian)(jian)、薄型平鍵(jian)(jian)(jian)(jian)、導向(xiang)型平鍵(jian)(jian)(jian)(jian)三種(zhong)。普(pu)通(tong)型平鍵(jian)(jian)(jian)(jian)對中性好(hao)，定位精度高(gao)，折裝方便，但(dan)無(wu)法實現(xian)軸(zhou)(zhou)上(shang)零(ling)件的軸(zhou)(zhou)向(xiang)固(gu)定，用于高(gao)速(su)或(huo)承受沖擊、變載荷的軸(zhou)(zhou)；薄型平鍵(jian)(jian)(jian)(jian)用于薄壁結(jie)構和傳遞轉(zhuan)矩(ju)較(jiao)小(xiao)的地方；導向(xiang)型平鍵(jian)(jian)(jian)(jian)用螺(luo)釘把(ba)鍵(jian)(jian)(jian)(jian)固(gu)定在軸(zhou)(zhou)上(shang)，用于軸(zhou)(zhou)上(shang)的零(ling)件沿軸(zhou)(zhou)移動量不(bu)大的場合。
