WebSep 15, 2024 · As an example, the principal features of the determination and inspection of the design parameters of a gear and a mating pinion that directly affect the gear mesh efficiency are considered in this paper. WebThis makes the gear tooth physically larger and reduces bending stress to an acceptable level. Of course, this increases specific sliding and reduces contact ratio and gear mesh efficiency, but this is better than broken teeth. There are two general approaches to reducing bending stress for the given tooth size.
