摘要
介绍了低温透平膨胀机工作轮、风机轮的超速工装设计和钎接轮的超速试验过程。得出选用ＬＤ２作为材质的钎接轮外形尺寸超差时的转速高于钎接焊缝处新裂纹产生时的转速这一实验结果。
This text tells of the designing of overspeeds frock of low temperature turbineexpansion-gear)s working wheels, fan wheels and the overspeef test process of braze-weldingwheels. The test results can be drawn as follow: When their form dimensions exceed the tolerance, the rotate speed of the braze-welding wheels whose material is LD2 will be higher than thatwhen the new flaws appear at the braze-welding seams.
