    摘要： A tool for the contact-free support of discs by gas streams impinging on discs when emerging from the supporting face of the tool at an acute angle to the disc surface, which comprises a body having a supporting face, bores within said body for connection with an extraneous gas reservoir, means in said body directed at an acute angle with respect to the supporting face for discharge of gas flowing from the reservoir, said flow-through means consisting of nozzles or recesses being position at equal distance from each other on the surface of a cone whose base is enclosed by a circle concentric with an imaginary circle on the supporting face, said circle having a diameter of 0.2-0.6 supporting face-diameters, the cone having an angle of 20.degree.-150.degree. at the apex, and wherein the distance of the flow-through means on the surface of the cone is from 2/3r.pi. to 0r, measured at the periphery of the circle, and the radial widths of the flow-through means in the supporting face are about 0.02-3% of the supporting face diameter.

    摘要翻译： 一种工具，用于当从工具的支撑面以与盘表面成锐角的方式撞击在盘上时由气流接触的盘的无接触支撑，所述工具包括具有支撑面的主体，用于连接所述主体内的孔 与外部气体储存器相关联的装置在所述主体中相对于支撑面以锐角指示，以排出从储存器流出的气体，所述流通装置由喷嘴或凹槽组成，其位置在彼此相等的距离上 其底部由支撑面上的假想圆同心圆的圆锥体的表面，所述圆的直径为支撑面直径的0.2-0.6，锥体在顶点具有20°-150°的角度， 并且其中所述锥体表面上的所述流通装置的距离在所述圆的周边处测量为2 / 3r pi至0r，并且所述支撑面中的所述流通装置的径向宽度为约 支撑面直径的0.02-3％。
