摘要： An electric abrasive sharpener for sharpening edges having pairs of interlocking abrasive wheels formed with opposite abrasive helical threads. Each end of the threads respectively has lead-in section and lead-out section having chamfer edge portion to eliminate kickback. The abrasive wheels of the sharpener is driven by a single phase AC motor connected to a motor drive that steps down the rotational speed of the output shaft of the motor to rotate the abrasive wheels with increased torque.

摘要翻译： 一种用于磨边的电磨刀，具有形成有相对磨料螺旋螺纹的互锁砂轮对。 螺纹的每一端分别具有导入部分和导出部分，其具有倒角边缘部分以消除反冲。 磨刀器的磨轮由连接到电动机驱动器的单相AC电动机驱动，该电动机驱动器降低电动机的输出轴的转速，以使转轮以增加的转矩旋转。
