高速电主轴永磁体减振装置
摘要：
高速电主轴永磁体减振装置是涉及一种高速电主轴永磁体减振装置结构的改进。本发明提供了一种结构简单、可降低电主轴振动，延长电主轴轴承寿命的高速电主轴永磁体减振装置。本发明包括壳体，壳体内两端设置有轴承，具有转子的电主轴设置于轴承上，定子相应于转子设置于壳体内部，其结构要点电主轴上位于转子与两侧的轴承之间分别设置有内磁圈；相应于内磁圈的壳体内侧设置有外磁圈；内磁圈与外磁圈的南极方向设置为一致。
摘要（英）：

The invention relates to an improvement of a permanent magnet damping device structure for a high-speed motorized spindle, and provides a permanent magnet damping device for a high-speed motorized spindle. The permanent magnet damping device for the high-speed motorized spindle is simple in structure and capable of reducing vibration of the motorized spindle and prolonging service life of motorized spindle bearings. The permanent magnet damping device for the high-speed motorized spindle comprises a shell, bearings are arranged at two inner ends of the shell, the motorized spindle with a rotor is arranged on the bearings, and a stator corresponding to the rotor is arranged inside the shell. The permanent magnet damping device for the high-speed motorized spindle is structurally characterized in that an inner magnetic ring is arranged, between the rotor and each of the bearings on two sides, on the motorized spindle, outer magnetic rings are arranged on the inner side, corresponding to the inner magnetic rings, of the shell, and directions of south poles of the inner magnetic rings and the outer magnetic rings are set to be consistent.
