1.径向游隙的选择轴承的径向游隙并非越小越好,不是所有的轴承都要求最小的工作游隙,必须根据条件选用合适的游隙。国标GB4604- 93中,滚动轴承径向游隙共分5组,游隙值依次由小到大,其中0组为标准游隙。基本径向游隙组适合于一般的运转条件、常规温度及常用的过盈配合;在高温、高速、低噪声、低摩擦等特殊条件下工作的轴承则宜选用较大的径向游隙;对精密主轴用轴
1. The choice of radial clearance Radial clearance of bearings is not as small as possible, not all bearings require the minimum working clearance must be selected according to the conditions of the appropriate clearance. GB GB4604-93, the radial clearance of the rolling bearing is divided into 5 groups, the clearance values in turn from small to large, of which 0 group is the standard clearance. Basic radial clearance group suitable for general operating conditions, conventional temperature and commonly used interference fit; In high temperature, high speed, low noise, low friction and other special conditions of work bearing should choose a larger radial clearance; For precision spindle shaft
