解析法预计齿面刮伤通常基于临界温度的概念,认为在临界温度以上运转时出现破坏。目前刮伤分析把润滑液膜不适当的影响考虑进去了。齿轮啮合时轮齿滑动而产生摩擦热。当摩擦热超限时,润滑液膜失效,高速或重载齿轮齿面就会刮伤。润滑液膜失效使齿廓上很小的接触区域上金属与金属接触,产生金属瞬时熔合,引起齿面撕裂。 Analytical method is expected tooth flaking is usually based on the concept of critical temperature, that damage occurs when operating above the critical temperature. The current scratch analysis takes into account the inappropriate effects of the lubricant film. Tooth meshing gear teeth sliding friction heat generated. When the friction heat overrun, the lubricating film failure, high-speed or heavy gear tooth surface will scratch. The failure of the lubricating fluid film causes the metal to come into contact with the metal on the very small contact area on the tooth profile, resulting in a transient metal fusion that causes tearing of the tooth flank.
