本刊第七期“机床主轴和轴承的设计”一文介绍的轴承头,是由一种结构特殊的UKF双列滚珠轴承(图1a )和其它部件所组成,这种轴承的外形与DIN616单列滚珠轴承相同。其承载荷的滚珠1不用保持器支持,而用直径较小的隔离滚珠 2隔开,这些滚珠滚动在导向坏3上。内、外环上各有两条滚珠

The seventh issue of “Machine Tool Spindle and Bearing Design,” a presentation of the bearing head, is composed of a special structure UKF double row ball bearings (Figure 1a) and other components formed, the bearing shape and DIN616 single row ball The same bearing. The load-bearing balls 1 are separated by smaller cage balls 2 without retainer support and these balls roll on the guide rails 3. Inside and outside the ring has two balls
