Abstract

The invention provides a throttler for an air floatation part and an air floatation piston comprising the throttler. The air floatation part is provided with a mounting cavity for mounting the throttler and an air outlet hole which communicates with the mounting cavity; the local area or the whole area of the outer side face of the throttler is a rough surface, the throttler is fixedly connected to the air outlet hole in the mounting cavity in an interference fit connection mode, part of the rough surface of the throttler faces the air outlet hole, after air enter into the mounting cavity, and the air makes contact with the rough surface and flows into the air outlet hole through the rough surface to achieve gas throttling. Compared with single small hole throttling, the throttler has the advantages that the risk of dirt dust particle blockage can be reduced, the throttling reliability is improved, throttling is achieved through the rough surface, machining is easy, large-batch production and installation are convenient, and the cost is low.

Description

technical field [0001] The present application relates to the technical field of air-floating pistons, in particular to a restrictor for air-floating components and an air-floating piston including the restrictor. Background technique [0002] With the increasing application of gas lubricants, more and more attention has been paid to the research on air bearings, air bearings, pistons and other air bearings. Both the air-floating piston and the air-bearing bearing use a throttle to realize gas throttling and increase the gas flow rate, and then realize the throttling air-floating function of the air-floating piston and air-bearing. [0003] For air bearings, there are two kinds of restrictor structures commonly used, one is a small hole restrictor, and the other is a porous medium restrictor. Wherein, the structure of the small-hole restrictor is as follows: the small-hole restrictor is provided with a gas circulation channel with an open end, and the end of the gas circula...
