Measurement and Evaluation Method Study of Alignment Deviation of Double-helical Gear

Abstract The alignment deviation of the V-vertex two symmetrically arranged gears with different rotation directions is a unique geometric parameter double helical gears, which has an important effect on vibration, noise, and gear service life. Aiming to more accurately represent manufacturing accuracy their transmission performance, this paper proposes meaning v-vertex basis contact line tooth surface based apex characteristics gears. First, mathematical model flank established meshing theory. Secondly, method for measuring evaluating (full method) proposed. Eventually, validity convenience proposed measurement are verified by experiment. Experimental results showed that total evaluated full 0.0082 mm, meets design requirements in Reference 16. This provides new evaluation comprehensive accurate significant implications manufacture high-precision
