摘要: 锥齿轮大小端存在形状差异,传统单频电磁加热时锥齿轮表面淬火温度分布不均导致硬化层分布不均。为了解决该问题,设计了两种感应加热线圈结构(罩式线圈和仿形线圈),提出了基于异形线圈下的锥齿轮异步双频分段式迭代循环感应加热方法,构建了电-磁-热多参数耦合求解物理模型,并进行了感应加热试验验证。结果表明,罩式线圈可以对锥齿轮的齿底进行良好加热,仿形线圈可以对轮齿齿顶和齿面进行仿齿廓加热。在此基础上,建立的异步双频感应加热电-磁-热多场耦合模拟结果表明,异步双频感应加热循环状态对锥齿轮齿面温度分布的均匀性影响较大。异步双频感应加热总时间一定时,随着迭代次数的增加,有助于避免局部温度过高,提升仿齿廓和齿宽方向温度均匀性,当迭代循环到4次后,齿宽和齿廓方向上温差不再发生明显变化。随着中、高频感应加热时间比增加,锥齿轮齿面温度分布均匀性降低。对锥齿轮进行异步双频感应加热试验验证了所建温度场模型的正确性。

Abstract: Due to the shape differences between the large and small ends of bevel gears, uneven distribution of hardening layer was caused by uneven quenching temperature distribution on the surface of bevel gears during traditional single-frequency electromagnetic heating. To solve the problem, two induction heating coil structures (hood coil and profile coil) were designed, an asynchronous dual-frequency segmented iterative cyclic induction heating method for bevel gears based on profiled coil was proposed, a physical model of electric-magnetic-thermal multi-parameter coupling was constructed and verified by induction heating test. The results show that the hood coil can heat the tooth bottom of the bevel gear well, and the profile coil can profiling heat the top and surface of the gear tooth. On this basis, the simulation results of electric-magnetic-thermal multi-field coupling for asynchronous dual-frequency induction heating show that the cycle state of asynchronous dual-frequency induction heating has a large influence on the uniformity of the temperature distribution of the tooth surface of the bevel gear. When the total time of asynchronous dual-frequency induction heating is certain, with the increase of the number of iterations, it helps to avoid excessive local temperatures, and improve the uniformity of the temperature in the direction of the imitation tooth profile and tooth width, and when the iteration cycle is up to 4 times, the temperature difference in the direction of the tooth width and the tooth profile is no longer changed significantly. As the ratio of medium and high frequency induction heating time increases, the uniformity of temperature distribution on the tooth surface of the bevel gear decreases. The asynchronous dual-frequency induction heating test on the bevel gear verifies the correctness of the constructed temperature field model.
