机床及机构的工作质量和稳定性在很大程度上取决于齿轮的制造精度。为了检验这些齿轮,广泛地采用着利用光电原理的各种装置。尽管这些装置有各种各样的结构特点,但它们都具有一个共同的原则—所规定的各点之间角度测量的必要性。角距可以用同被检齿轮连在一起的装置记录下来。但在这种情况下,角度变换器的不连续性不应超过给定的周节测量误差,它通常不应大于2″。由于成批生产的变换器至少具有
The quality and stability of the work of machine tools and mechanisms depend very much on the manufacturing precision of the gears. In order to test these gears, various devices using the principle of photoelectricity are widely used. Although these devices have a variety of structural features, they all share a common principle - the need for angular measurement between points. The angular distance can be recorded together with the device being inspected gear. However, in this case, the discontinuity of the angle transducer should not exceed the given measurement error of the circumference, which should normally not be greater than 2 ". Since mass-produced transducers have at least
