| Abstract: | 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. |
