This paper studied the meshing stiffness and elastic deformation of high speed and high load gears, impact of mesh - in and mesh - out, internal dynamic load, vibration and noise. The authors present formulations which calculate. The original point and pressure angle of tip relief, and reduce the relation between tooth profile normal tip relief and tangential tip relief.

本文分析了高速、重载齿轮啮合刚度的变化和弹性变形的影响,以及由此产生的啮人、啮出冲击,传动过程中瞬时角速度发生变化而引起的附加动载荷、振动和噪声,给出了修缘起始点的计算公式以及修缘渐开线压力角与齿廓法向修缘量和齿顶圆切向修缘量的关系式。

According to the request of tip clearance measurement, we put forward a new optical fiber sensor with a configuration of single-bundle optical fiber for transmitting laser beam, and multi-bundle optical fibers for receiving the scattered light. The transmitting fiber lies in the center, and multi-bundle receiving fibers are around it. Through ratio operation of light intensity of different receiving optical fibers, the sensor has completely eliminated the effect of tip surface reflectivity variation on measurement...

According to the request of tip clearance measurement, we put forward a new optical fiber sensor with a configuration of single-bundle optical fiber for transmitting laser beam, and multi-bundle optical fibers for receiving the scattered light. The transmitting fiber lies in the center, and multi-bundle receiving fibers are around it. Through ratio operation of light intensity of different receiving optical fibers, the sensor has completely eliminated the effect of tip surface reflectivity variation on measurement result as well as the effect of inter-angle of tip surface with sensor end surface on measurement result greatly. With the help of rotation synchronized sensor, it can measure all the blade tips in real-time. When the rotating speed of blade changes from 0-120000r/min, the measurement range of tip clearance is from 0-3mm, and the measurement precision is 25μm.

根据叶尖间隙测量的要求,设计了一种新型的光纤传感器。它采用了单光纤传光、多组光纤束接收散射光的结构。发射光纤位于中心,周围均布多组接收光纤。通过各组接收光纤光强的比值运算,消除了叶尖表面反射率变化对测量结果的影响,也可减小叶尖表面与传感器端面夹角给测量结果带来的影响。在转速同步传感器的配合下,该传感器可以实时测量所有叶片的叶尖间隙。当叶片转速在0-12000r/min之间变化时,叶尖间隙的测量范围为0-3mm,测量精度为25μm。
