齿轮激光淬火硬化层的快速估算及背面回火问题

Fast Evaluation on the Case Depth of Laser Hardening Gear and the Gear Back Temper

采用平面瞬时热源法研究激光作用后轮齿内部的瞬态温度场分布，导出了实用的齿轮硬化层分布的快速估算公式，同时还讨论了齿轮的背面回火问题。

With plane transient heat source's solution,this paper analyzes the transient temperature field in a gear tooth induced by laser beam. And the formula used to fast evaluate the gear case depth is presented. The problem of gear back-temper of laser beam hardening is also discussed in the paper.
