目前,由于生产的发展,各种热处理零件不仅数量多,而且质量要求较高。我厂生产的齿轮,是在自制的井式气体渗碳炉中渗碳处理的。风扇轴是气体渗碳炉中最易损坏的一个构件。风扇轴长期在900～950℃高温状态下工作,并以1450转/分的转速带动风扇旋转。新安装的风扇轴和风扇,虽然在专用动平衡机上经过了严格的校正,但在上述工况下,由于高温变形便失去了原有的平衡,从而使风扇轴受
At present, due to the development of production, not only a large number of heat treatment parts, and higher quality requirements. The gear produced by our factory is carburized in a self-made pit type gas carburizing furnace. The fan shaft is the most easily damaged component of a gas carburizing furnace. Fan shaft long-term work at 900 ~ 950 ℃ high temperature, and 1450 rev / min speed drive fan rotation. Although the newly installed fan shaft and fan have been rigorously calibrated on a dedicated balancing machine, the original balance is lost due to the high temperature deformation under the above conditions, so that the fan shaft
