振动式空气轴承,是几年前机械技术公司为美国国家航空和宇宙航行局研制的。最近试用于机器上,运转结果很好。据该公司进一步试验表明,这种轴承能支承低速和高速主轴,摩擦很小,也可用在活塞上。从某些方面来看,可以认为是一种自压缩空气轴承,而且它还具有能够支承低速移动负载或静止负载的特点。 Vibratory air bearings were developed by NASA a few years ago for NASA. Recently tried on the machine, running very well. According to the company further tests show that this bearing can support low-speed and high-speed spindle, friction is small, can also be used on the piston. In some ways, it can be considered a self-contained air bearing, and it has the ability to support low-speed moving loads or stationary loads.
