直齿轮的可靠性设计

Gear with high efficiency, compact structure, reliable and stable transmission ratio and other characteristics, widely used in mechanical transmission. All the gear failure mode, the teeth surface contact strength and tooth root bending strength is a major failure in the form of two gears, gear reliability and therefore research is necessary, the article describes the contact strength of gear and tooth root bending strength the reliability of the design and calculation and comparison with the safety factor method, the reliability of the design and analysis of the pros and cons of traditional algorithms. To improve the reliability and service life of gear has important theoretical and engineering application.
