Description

Technical Field

[0001] The utility model relates to the technical field of air floating sliders, in particular to a marble air static pressure air floating slider. Background Art

[0002] The working principle of the marble air static pressure air floating slider is based on air static pressure technology. When the high-pressure gas is injected into the throttle hole through the air channel inside the air floating support, the gas flows out of the throttle hole and enters the pressure equalizing cavity in the air film gap. It is throttled again at the edge of the pressure equalizing cavity, and then enters the air film and diffuses radially. In this way, a lubricating air film is formed between the air floating support and the marble thrust surface, realizing non-contact support and sliding.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: most of the marble air static pressure floating sliders need to be used in conjunction with special slide rails, and there is no direct contact between the air floating slider and the guide rail, so the influence of the micro-convexities on the surface of the guide rail on the sliding accuracy can be eliminated, thereby achieving high-precision sliding; since the slider needs to be maintained during long-term use, and the traditional slider fixing method is relatively cumbersome, it is easy to cause inconvenience in disassembly and assembly during actual maintenance; therefore, a marble air static pressure floating slider is proposed to address the above problems.
