Practicable Methods of Measuring Helix Angle of Helical Gear

According to the experience from practice, this article sums up three practicable methods of measuring helix angle of helical gear. The method of rolling and tracing is simple and direct.The method of accuracy-measuring is comparatively accurate.While the method of machine-tool examining is capable of eliminating the errors caused by wear and tear,The above three methods are all easy to operate and each has its strong points.If they work in coordination,the effect is quite good.These methods are really feasible.
