混合支承结构是指在转子系统的一个支承结构中同时并联或串联使用滚动轴承和滑动轴承。结合国内外现有的混合支承结构,对转子系统中混合支承的工作原理和工作特点进行了分析,并给出了混合支承的应用背景和设计准则,指出采用混合支承结构的转子系统能够满足大承载、高转速、启、制动频繁的工作条件,具有启动力矩小、承载能力大等独特的优点,可在单独使用滚动轴承或者滑动轴承时,转子支承的可靠性和工作性能无法得到保障的条件下,使转子系统具有良好的工作性能和更长的使用寿命。
Hybrid support structures refer to the use of rolling bearings and plain bearings in parallel or in series in one support structure of a rotor system. Combining the existing hybrid support structures at home and abroad, the working principle and working characteristics of hybrid support in rotor system are analyzed. The application background and design criteria of hybrid support are given. The rotor system with hybrid support structure can meet the requirements of large Bearing, high speed, Kai, brake frequent working conditions, with a small starting torque, bearing capacity and other unique advantages, can be used alone in rolling bearings or plain bearings, rotor support reliability and performance can not be guaranteed conditions Under, so that the rotor system has good working performance and longer service life.
