切利亚宾斯克工厂研制出一种ПКЗВ型仪器。用它可保证提高直径达400mm,重15Kg多的齿圈的径向跳动的接触线方面的测量精确度。测量仪器包括;用来给径向和端面跳动小于等于0.003mm的齿圈作定位用的仪表台1;带锥心心轴的轴套2;正弦装置8;带由弹簧作用的
The Chelyabinsk factory developed a ПКЗВ-type instrument. Use it to ensure that the diameter of the ring up to 400mm, weighing more than 15Kg radial run-out contact line measurement accuracy. Measuring instruments include; instrument used to position the ring gear with radial and face runout less than or equal to 0.003mm; bushing with conical mandrel 2; sinusoidal device 8; with spring action
