测量斜齿轮的螺旋角,一般需要使用价格昂贵的仪器。我厂是个生产陶瓷机械的中小型工厂,没有这些设备,产品零件中的斜齿轮螺旋角,精度要求为4级,无法测量怎么办?在伟大的批林批孔运动中,狠批了林贼、孔老二鼓吹的“上智下愚”等反革命谬论,经过几个月的努力,我厂计量室终于自制成测量斜齿轮螺旋角的新工具——“螺旋角测定器”。该量具结构简单、使用方便,经过多次实验,效果良好,适合一般中小型机械厂的生产需要。螺旋角测定器的结构如图所示。在基板13上用两个螺钉14固装着刻度盘7,刻度盘上的螺钉穿
Measuring the helix angle helical gear, the general need to use expensive instruments. I plant is a small and medium-sized factory producing ceramic machinery, without these devices, helical gear helical angle of the product parts, accuracy requirements for the 4, can not measure how to do? , Kong Laos two advocated “wisdom on the fool” and other counter-revolutionary fallacies, after several months of efforts, I plant measurement room finally made self-measuring helix angle helical gear new tool - “helix angle detector.” The measuring tool has the advantages of simple structure, convenient use, good effect after many experiments, and is suitable for the production needs of general small and medium sized machinery factories. The structure of the helix angle detector is shown in the figure. A dial 7 is fastened to the base plate 13 by two screws 14, and a screw on the dial is worn
