高速轻载旋转机械的径向轴承是机器的关键部件之一。据国外一些资料统计,在若干台输送卤素碳氢化合物制冷剂的离心式冷冻压缩机的损坏零件中,径向轴承为损坏件总数的14%,占该类机器损坏件的第三位。因为沿用的圆柱轴承存在着振动大、温升高、易研易烧坏,特别易产生油膜自激振荡的问题,在使用中容易造成被迫停机或严重损坏设备,从而造成整个装置停产(离心压缩机一般无备用机组)的重大事故。因此,人们
Radial bearings for high-speed light-duty rotary machines are one of the key components of the machine. According to some statistics from abroad, among the damaged parts of several centrifugal refrigeration compressors delivering halogenated hydrocarbon refrigerants, the radial bearings are 14% of the total number of damaged parts and the third place of damaged parts of such machines. Cylindrical bearings are used because of the existence of vibration, high temperature, easy to research and easy to burn out, especially easy to produce oil film self-oscillation, the use of easily lead to forced shutdown or serious damage to equipment, resulting in the entire device shutdown (centrifuge Compressor generally no spare unit) a major accident.
