摘要
介绍了作者单位研制的一种高速大功率电主轴的结构。其中的创新点有铬锰弹簧钢转子内套的注油孔和环形内槽,方便了机床主轴和电动机转子的拆卸。另外在后轴档的轴承支承座外圈加一滚套的设计,解决了因主轴热变形导致的轴承预紧力过大的问题。
Author describes the development of a high speed motorized spindle.Innovation which have Cr-Mn steel rotor spring sets and the injection hole in the ring slot,the convenience of the machine tool spindle and the demolition of the motor rotor.Other files in the rear axle outer bearing blocks plus one roller set design,to solve due to thermal deformation caused by the spindle bearing preload are too extensive.
