动静混合轴承是七十年代发展起来的一种新型技术,它综合了动压和静压的优点。混合轴承的刚性高而且在功耗小的情况下承载能力大。如果选择合理的参数,可使轴承的油膜在零速到最大转速或零偏心到最大偏心的范围内有很大的刚性。美国通用电机公司工程机械实验室的Rohde S.M.和Ezzat H.A.详细地研究了混合轴承的动态特性,特别注意了润滑油的压缩性,认为高的偏心振动频率会使轴承的刚度和阻尼发生很大的变化。 Dynamic and dynamic hybrid bearings developed in the seventies a new technology, which combines the advantages of dynamic and static pressure. High rigidity of hybrid bearings and load capacity in the case of small power consumption. If you choose a reasonable parameter, the bearing oil film in the zero speed to maximum speed or zero eccentricity to the maximum eccentric range has great rigidity. Rohde SM and Ezzat HA of General Motors Construction Machinery Laboratory studied the dynamic characteristics of hybrid bearings in detail, paying particular attention to the compressibility of the lubricating oil, and considered that the high eccentric vibration frequency would cause great stiffness and damping of the bearing Variety.
