摘要： An improved drive system for machines incorporating air bearings is disclosed. The drive system eliminates backlash, introduces no vibrations or noise into the moving structures, requires no lubrication and excells in being compact and simple. The drive system essentially includes a stationary bar mounted in one axis of motion of the machine, a wedge member mounted for drivingly engaging the bar on one side, a preloader mounted for operatively engaging the bar on the opposite side, and a pair of springs urging the preloader to urge the wedge member into driving engagement with the bar. The drive system is coupled to a positioning servo system, which provides control of the drive system's position and speed. Preferably, the wedge angle of the wedge member is from about 15.degree. to about 30.degree.. Preferably, both the bar and the wedge member are formed from a group of materials possessing at least about 65 Rockwell hardness.

摘要： A linear test gage for testing the accuracy of machine tools is operable for out of roundness measurements as well as long-range linear measurements. The test gage consists of a linear guide assembly, first and second reference elements, and a long-range linear measurement device. The linear guide assembly includes an elongated guide profile, a guide rail secured to the guide profile, and a slide which is slidably movable relative to the guide rail. The first reference element is attached to the first end of the guide profile and the second reference element is attached to the slide so that the reference elements are relatively movable over a length of about 30-40 inches. A first knuckle assembly secures the first reference element in a fixed position relative to the machine tool. A second knuckle assembly secures the second reference element to an active element of the machine tool. During testing, the active machine element is programmed to move the second reference element along a predetermined trajectory wherein the linear guide assembly permits co-linear movement of the reference elements as the active element moves the second reference. The long-range linear measuring device measures the distance between the reference elements as the second reference element is moved. The long range measurement capability allows use of the device in both circular and linear measurements. The test gage further includes a counter weight assembly and an anti-rotation device.
摘要翻译：用于测试机床精度的线性测试仪可用于圆度测量以及远程线性测量。测试仪由直线导向组件，第一和第二参考元件以及远程线性测量装置组成。线性引导组件包括细长的引导轮廓，固定到引导轮廓的导轨和相对于导轨可滑动地移动的滑块。第一参考元件附接到引导轮廓的第一端，并且第二参考元件附接到滑块，使得参考元件可在约30-40英寸的长度上相对移动。第一关节组件将第一参考元件固定在相对于机床的固定位置。第二转向节组件将第二参考元件固定到机床的有源元件。在测试期间，有源机器元件被编程为沿着预定轨迹移动第二参考元件，其中当有源元件移动第二参考时，线性引导组件允许参考元件的共线运动。当第二参考元件移动时，远程线性测量装置测量参考元件之间的距离。长距离测量功能允许在圆形和线性测量中使用该设备。测试计进一步包括配重组件和防旋转装置。
