摘要： In a metrological or other sensitive apparatus, the transducer or other operative member (22) is mounted on a support structure (14 to 18) which is carried on a chassis (2) by a first set of dampers or isolating means (10) and the chassis (2) is mounted on the floor by a second set of dampers or isolating means (6). The two sets (10, 6) have different natural frequencies and the first set (10) is arranged so that any vibration of the support structure tends to be rotational centered in the zone of operation (21) of the transducer or other member. This is achieved by arranging that the stiffness of the first set of dampers (10) is higher in the direction (24) passing through the zone of operation (21) than in the transverse direction.

摘要： A bearing structure, preferably for supporting a rotary table (4) in metrological apparatus, includes both a journal bearing (34,36,38) and a thrust bearing (56,66). The journal bearing is made up of three dry pads (34,36,38), one (38) of which is radially adjustable, and the thrust bearing (56,66) comprises first and second air bearings. The axis of rotation of the bearing is vertical, and the lower (66) of the air bearings is less stiff than the upper one (56).

摘要： Metrological apparatus is provided with a turntable (4) which is movable horizontally and pivotally for centering and levelling. The turntable (4) is supported at three points (A,B,P), one (P) of which is fixed and the other two (A,B) of which are vertically movable by motorized jacks. Centering and levelling is achieved automatically by means of a computer (72) which calculates the required horizontal and pivotal movements of the turntable (4) from data obtained by sensing the workpiece surface with a transducer (12).

摘要： A metrological apparatus has a movable arm 15 which moves up and down between two bearing members 13, both of which define datum positions for the arm 15. The arm 15 has air bearings on the bearing members 13, so that it adopts a position equidistant between the bearing members 13. In this way, the position of the arm 15 contains the average of the errors in the two datum positions defined by the bearing members 13. Where the bearing members 13 have symmetric errors, these will be cancelled. Since the path of maximum straightness of movement of the arm 15 is spaced from the bearing members 13, it is possible to put a workpiece 3 in this path and a turntable 5 for supporting the workpiece 3 is arranged to have its rotational axis in line with the path of maximum straightness. The vertical position of each end of the arm 15 is measured using a respective grating 25 and the average of the measurements is taken to provide an accurate measurement of the height of the centre point of the arm 15 over the workpiece 3, substantially free of Abbe errors.
摘要翻译： PCT No.PCT / GB93 / 00037 Sec。 371日期：1994年7月8日 102（e）日期1994年7月8日PCT提交1993年1月8日PCT公布。出版物WO93 / 14367 日期1993年7月22日计量装置具有可移动臂15，该可动臂15在两个轴承构件13之间上下移动，两个轴承构件均限定了臂15的基准位置。臂15在轴承构件13上具有空气轴承，在轴承构件13之间采用等距离的位置。这样，臂15的位置包含由轴承构件13限定的两个基准位置中的误差的平均值。当轴承构件13具有对称误差时，这些将是取消。由于臂15的最大平直度的运动路径与轴承构件13间隔开，因此可以将工件3放置在该路径中，并且用于支撑工件3的转台5被布置成使其旋转轴线与最大直线的路径。使用相应的光栅25测量臂15的每个端部的垂直位置，并且采用测量的平均值来提供臂15在工件3上的中心点的高度的精确测量，基本上不含Abb + E，acu e + EE错误。
