減速機

      減(jian)速(su)器是一種由封閉在剛(gang)性殼(ke)體內的齒輪傳(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿(gan)傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪-蝸(gua)桿(gan)傳(chuan)(chuan)動(dong)(dong)(dong)所組成的獨立部件，常用作(zuo)(zuo)原動(dong)(dong)(dong)件與工(gong)作(zuo)(zuo)機(ji)之間的減(jian)速(su)傳(chuan)(chuan)動(dong)(dong)(dong)裝置 。在原動(dong)(dong)(dong)機(ji)和工(gong)作(zuo)(zuo)機(ji)或執行機(ji)構之間起(qi)匹配轉(zhuan)速(su)和傳(chuan)(chuan)遞轉(zhuan)矩的作(zuo)(zuo)用，在現(xian)代機(ji)械中應用極(ji)為廣泛。
