内齿轮的许多精度项目的检验均感困难,一般齿轮量仪诸如手携式周节仪、基节仪、公法线千分尺,乃至万能测齿仪都不能用于内齿轮,迄今尚无通用内齿轮量仪可供使用。针对这种情况,今介绍一种适用于生产现场的简易周节仪、基节仪、公法线长度仪,供参考。本文所述内齿轮量仪系采用北京量具刃具厂生产的杠杆千分表(分度值2μm]直接安装在自制的底板上,经极简单的改装而成(只须拆除一些外
Many of the internal gear precision test are difficult, general gear measuring instruments such as hand-held instrument week, instrument, common-law micrometer, and even universal tooth-detector can not be used for internal gear, there is no universal internal gear measuring instrument Available for use. In view of this situation, this article introduces a simple for the production of the week-week device, Ji Ji, the common-law length of the instrument for reference. This article describes the use of internal gear measuring instrument Beijing Measuring Tool & Cutter Lever dial gauge (graduation value 2μm] installed directly on the self-made floor, the very simple modification made (just remove some
